Hunter's modular residential and light-commercial controller; the current P2C-400 generation replaced the original Pro-C in 2023 and is backward compatible with older PC-400 station modules.
Specs: 4-station base, conventional wiring to 23 stations with PCM-300/PCM-900/PCM-1600 modules; hybrid EZ Decoder (PC-DM) up to 32 stations (28 if two-wire only); 3 programs x 4 start times; 2 sensor inputs (Clik or Solar Sync); 1 P/MV output; optional Seconds Mode run times; 120 VAC in, 24 VAC 1 A out, 0.56 A per station, 0.28 A P/MV; IP44; optional PC-WIFI module (2.4 GHz only, WPA/WPA2) for Centralus software; SmartPort harness for ROAM remotes; warranty 2 years
Tech note: Only PC-400 panels dated March 2014 or newer accept the HPC-FP Hydrawise face panel (PC-300 is not compatible); PC-300 (2002-2006) used grey/black modules that are no longer available. The 9 V battery keeps time only; the controller cannot run valves without AC. Easy Retrieve saves a backup program that survives a reset.
Hunter's entry-level fixed-station residential controller with a dedicated Solar Sync dial position.
Specs: 2, 4, 6 or 8 stations (XC-200i/400i indoor; XC-400/600/800 outdoor with key lock); 3 programs x 4 start times, run times up to 4 hours; 1 sensor input; 1 P/MV; 120 VAC in, 24 VAC 1 A, 0.56 A station, 0.28 A P/MV; plastic IP54 outdoor; QuickCheck, Easy Retrieve, Cycle and Soak, Seasonal Adjust, Delay Between Stations, programmable rain delay; EPA WaterSense when paired with Solar Sync; warranty 2 years
Tech note: Replacement transformers: indoor 120/24 VAC P/N 526500, outdoor 120/24 VAC P/N 468000. Remove the battery contact insulator so the backup battery keeps time during outages. Full reset: hold the three front buttons, press RESET on the right side, release when DONE shows.
Hunter's current fixed-station controller that becomes a Hydrawise Wi-Fi controller when the plug-in WAND module (sold separately) is installed.

Hydrawise Wi-Fi version of the ICC2 for larger residential and commercial sites.
Specs: 8-station base to 38 or 54 stations depending on model (same 4/8/22-station modules as ICC2; up to 54 EZ decoder stations); plastic (IP55), metal, stainless wall mount or plastic pedestal (IP24); 120/230 VAC in, 24 VAC 1.4 A, 0.56 A station, 0.56 A P/MV; 2.4 GHz only; built-in milliamp sensor; HC Flow Meter support; ROAM/ROAM LR compatible; HCC-FPUP retrofit kit for ICC/ICC2; warranty 2 years
Tech note: Overcurrent threshold 1,200 mA. Only the HCC supports Wireless Valve Link alerts (low battery, unable to start).
Hunter's flagship 3/4" residential rotor with automatic arc return and a non-strippable, vandal-resistant drive.
Specs: Radius 17'-46'; flow 0.36-14.8 GPM; 3/4" NPT inlet; 34 nozzles (blue standard 1.5-8.0, gray low-angle 2.0-4.5, black short-radius 0.50-3.0, green 6.0-13.0, MPR-25/30/35 matched-precip); recommended 25-70 PSI, operating 20-100 PSI; ~0.4 in/hr; trajectory 25 deg standard / 13 deg low-angle; arc 50-360 deg, part- and full-circle in one unit; shrub, 4", 6", 12" bodies; optional drain check valve (CV) to 10' elevation; reclaimed (R) ID; warranty 5 years
Tech note: Headed/slotted set screw takes the Hunter wrench or a flat-blade screwdriver; radius screw P/N 180900. Riser seal kit (10 seals + spring seat) P/N 253400 fits PGP, PGP Ultra and I-20-12; seal only P/N 181500. The small hole on the riser side is a drain/flush hole and is supposed to drip.
The original PGP rotor, still sold, with a 40-360 deg arc and 12 red nozzles included.
Specs: Radius 22'-52'; flow 0.5-14.1 GPM; 3/4" inlet; 27 nozzle options (standard red, standard blue, gray low-angle); recommended 25-70 PSI, operating 20-100 PSI; ~0.4 in/hr; check valve available (4' check height); warranty 2 years
Tech note: Radius screw P/N 120300SP; turning it clockwise more than five full turns can eject the screw.
Compact 1/2" rotor that gives rotor coverage in spray-head sized areas.
Specs: Radius 15'-34'; flow 0.42-4.3 GPM; 1/2" inlet; 8 nozzles, 2.0 nozzle factory installed; recommended 30-50 PSI, operating 20-100 PSI; ~0.6 in/hr; trajectory ~14 deg; arc 40-360 deg; shrub (PGJ-00), 4", 6", 12"; -V models have factory drain check valve (to 7'), -R reclaimed; warranty 2 years
Tech note: Field check valve P/N 462078SP (not for PGJ-00); radius screw P/N 537900. Rubber cover and QuickCheck arc mechanism; adjusts with the same white Hunter wrench as the PGP.
Commercial-grade 3/4" rotor that shares PGP Ultra nozzles and adds FloStop, a standard check valve and optional stainless riser.
Specs: Radius 17'-46'; flow 0.36-14.8 GPM; 3/4" NPT; 34 nozzles (same racks as PGP Ultra); recommended 25-70 PSI, operating 20-100 PSI; ~0.4 in/hr; arc 50-360 deg; shrub, 4", 6", 12"; drain check valve standard (to 10'), NCV models without; SS stainless riser option; PRB pressure-regulated body option; rubber cover; warranty 5 years
Tech note: FloStop: with the zone running, insert the Hunter wrench in the hole in the center of the rubber cover and turn clockwise to shut that one head off for nozzle swaps. I-20 riser seal only P/N 252500.
Large-turf 1" rotor with high-torque gear drive and built-in check valve.
Specs: Radius 37'/40'-71'; flow 3.8-31.5 GPM; 1" NPT; 11 nozzles (five included; 4-28 available); operating 40-100 PSI; ~0.4 in/hr; trajectory 25 deg; arc 50-360 deg; 4" and 6" pop-up, plastic or stainless riser, high-speed (HS) and reclaimed options; warranty 5 years
Tech note: Automatic arc return and non-strippable drive like the PGP Ultra; needs at least 40 PSI, so it is rarely right for a residential 1" meter.
Hunter's economy short-range 1/2" rotor, a budget alternative to sprays.
Specs: Radius 15'-34'; flow 0.42-4.3 GPM; 1/2" inlet; 8 nozzles, 2.0 installed; recommended 30-50 PSI, operating 20-100 PSI; ~0.6 in/hr; arc 40-360 deg; SRM-04 (4") only, no check valve; warranty 1 year
Tech note: User-installed drain check valve P/N 462078SP (to 7'); same through-the-top arc adjustment as the PGJ.
Hunter's standard pop-up spray body that accepts female-threaded spray nozzles and MP Rotators.
Specs: 1/2" inlet; shrub adapter (PROS-00), 2", 3", 4", 6", 12" pop-ups; operating 15-100 PSI; check valve (CV) on 4", 6", 12" to 10' elevation; side-inlet (SI) 6" and 12"; reclaimed cap; warranty 5 years
Tech note: Accessories: shutoff cap P/N 213600SP, shutoff nozzle P/N 916400SP, reclaimed ID cap P/N 458520SP. Non-regulated, so spray nozzles mist at high pressure; Hunter pairs sprays with PRS30.
Pro-Spray body with an in-stem regulator that holds 30 PSI at the nozzle for conventional spray nozzles.
Specs: Brown cap; 1/2" inlet; shrub, 3", 4", 6", 12"; operational 15-100 PSI; CV option; FloGuard (-F) option on 4", 6", 12"; reclaimed (-R); warranty 5 years
Tech note: Use PRS30 under an MP Rotator only when you need the minimum radius (MP radius bottoms out at 30 PSI); Hunter says PRS bodies save up to 30% water versus unregulated bodies.
Pro-Spray body regulated to 40 PSI, the optimum pressure for MP Rotator nozzles.
Specs: Gray cap; 1/2" inlet; shrub, 3", 4", 6", 12"; CV option; FloGuard (-F) option; reclaimed (-R); side-inlet 6" and 12"; warranty 5 years
Tech note: Cap color is the field ID: gray = 40 PSI (MP Rotator), brown = 30 PSI (sprays).
Multi-stream rotating nozzle that fits any Pro-Spray body and applies water at about 0.4 in/hr, far slower than a fixed spray.
Specs: MP1000 8'-15' (maroon 90-210 deg, light blue 210-270, olive 360); MP2000 13'-21' (black 90-210, green 210-270, red 360); MP3000 22'-30' (blue 90-210); MP3500 31'-35' per Hunter cutsheet; MP-CORNER 8'-15', 45-105 deg, turquoise; ~0.4 in/hr; recommended 40 PSI, minimum radius at 30 PSI; radius reduction up to ~25%; female thread (HT = male thread); warranty 3 years
Tech note: Hunter states operating pressure above 55 PSI shortens nozzle life, speeds rotation, hurts uniformity and voids the trade warranty, so put MPs on PRS40 bodies. Arc only adjusts while popped up and running; a slip clutch stops you closing the radius fully. Removable inlet filter screen (MP3000 uses 20 mesh).
Higher-precipitation MP Rotator for small spaces and spray retrofits.
Specs: MP-800SR 6'-12' (gray/orange 90-210, gray/lime 360); MP-815 8'-16'; MP-820 15'-24'; 0.8 in/hr; recommended 40 PSI, minimum radius at 30 PSI; radius reduction ~25%; double-pop; warranty 3 years
Tech note: 0.8 in/hr does not match standard MPs at 0.4 in/hr; Hunter says zone MP800s separately. MP800SR-90 uses a finer 60-mesh screen.
MP Rotators for 5'-wide strips: side strip and left/right corner strips.
Specs: MP-SS-530 side strip 5' x 30' (brown); MP-LCS-515 left corner 5' x 15' (ivory); MP-RCS-515 right corner 5' x 15' (copper); recommended 40 PSI, minimum radius at 30 PSI; female (HT = male); warranty 3 years
Tech note: Factory arcs: side strip 180 deg, corner strips 90 deg. Match their precipitation to standard MPs (single row/triangular) or MP800s (rectangular) per Hunter's layout note.
Variable-arc spray nozzles for Pro-Spray bodies; only the 4' and 6' sizes remain current.
Specs: 4A (4') and 6A (6'), arc adjustable 0-360 deg, female thread; recommended 30 PSI; pair with PRS30; warranty 2 years
Tech note: 8A, 10A, 12A, 15A and 17A were phased out in 2026; Hunter names Pro High-Efficiency Nozzles as the replacement.
Fixed-arc spray nozzles in six radius families.
Specs: 5', 8', 10', 12', 15', 17' radius; Q = 90 deg, T = 120 deg, H = 180 deg, F = 360 deg (e.g. 15H = 15' half); radius can be reduced; female thread; recommended 30 PSI; pair with PRS30; warranty 2 years
Tech note: Hunter publishes performance data per nozzle; on a 30 PSI PRS30 body the stamped radius is the design radius.
Hunter's standard residential 1" solenoid valve, 100% factory water-tested.
Specs: Flow 0.2-40 GPM; recommended 20-150 PSI; 150 F; globe (G), angle (A), male x male (MM), male x barb (MB, 3/4" or 1 1/4" barb) bodies; -100 no flow control, -101 flow control; -S slip, -DC latching solenoid (P/N 458200), -LS no solenoid; 24 VAC solenoid 350 mA inrush / 190 mA holding at 60 Hz; reverse-flow solenoid; double-beaded diaphragm; Accu Sync regulator option; warranty 2 years
Tech note: Hunter valves need at least 20 PSI to close. Manual open: solenoid 1/4 turn CCW or bleed screw 1/4 turn; closes within 15 s when retightened. 1 1/2" PGV-151 = 20-120 GPM, 2" PGV-201 = 20-150 GPM. Diaphragm is interchangeable across PGV, SRV and ASV 1" valves.
1" PGV with a hand-threaded bonnet ring instead of bonnet screws for tool-free service.
Specs: Flow 0.2-40 GPM; 20-150 PSI; G/MM/MB bodies, slip (S) option; -100 no flow control, -101 flow control; same 24 VAC 350/190 mA solenoid; DC and LS options; warranty 2 years
Tech note: Hand-tighten the ring only; over-tightening damages the valve. Debris under the diaphragm is the number one cause of a weeping jar-top.
Hunter's commercial glass-filled-nylon globe valve for high pressure and dirty water.
Specs: 1", 1 1/2", 2", 3" (ICV-101G 0.1-40 GPM; 151G 0.1-150; 201G 0.1-200; 301 0.1-300 GPM); 20-220 PSI; flow control standard; Filter Sentry (FS) self-cleaning filter option, can be added to an installed valve; FS-R reclaimed with purple knob and chlorine-resistant diaphragm; DC and LS options; warranty 5 years
Tech note: Filter Sentry wipes the filter every time the valve opens, which is what to spec on well or pond water.
Rain sensor with Quick Response that interrupts the controller within minutes of rain starting rather than after a set depth.
Specs: RAIN-CLIK wired (25' of 20 AWG two-conductor wire), RAIN-CLIK-NO normally open, RFC rain/freeze, WR-CLIK wireless kit (sensor, receiver, aluminum mount); shutoff ~2-5 min, reset ~4 h in dry sun; 3 A switch at 24 VAC; wireless 433 MHz, 800' line of sight, freeze shutoff 37 F on wireless; warranty 5 years
Tech note: Test only in Manual All Stations or an automatic cycle; Manual Single Station overrides the sensor. Wireless: press the spindle, the LED should flash (battery good); after a power outage the receiver LED stays red until it resyncs (hold Test 5 s).
Classic cup-and-disc rain sensor with adjustable rainfall set point.
Specs: Adjustable 1/8" to 3/4" of rainfall; MINI-CLIK (25' wire, aluminum mount), MINI-CLIK-C conduit mount, MINI-CLIK-NO normally open; WM-CLIK wireless rain/freeze (37 F), 433 MHz, 800' line of sight; 3 A switch; warranty 5 years
Tech note: No maintenance and no winter removal needed. If the system never shuts off, move the cap to a more sensitive setting, check for overhangs or trees blocking rain, and confirm the SEN jumper was removed at the controller.
Soil-moisture probe and module that stops irrigation when the root zone is wet enough.
Specs: SC-PROBE probe + module; 5 A switch at 24 VAC; 100 mA input; up to 1,000' from module to probe on AC systems; connects to sensor inputs or interrupts the common wire of any 24 VAC controller; warranty 5 years
Tech note: Pairs with NODE-BT (probe only) and with Solar Sync for ET-plus-moisture control.
ET weather sensor that measures sunlight and temperature and rewrites the controller's Seasonal Adjust every day, with built-in Rain-Clik and Freeze-Clik shutoff.
Specs: SOLAR-SYNC-SEN wired (25' wire, gutter mount); WSS-SEN wireless (433 MHz, 800' LOS, receiver included); WSS-TR transmitter, WSSR receiver; freeze shutoff 37 F; Region 1-4 and Water Adjustment 1-10 (default 5); works with X-Core, Pro-C, X2, ICC2, HCC and most Hunter controllers; warranty 5 years from the date code
Tech note: The Bypass switch only disables the rain/freeze shutoff; it does not stop the automatic seasonal adjust. To remove it permanently you must 'uninstall' it at the Solar Sync dial position (dashes shown) or the controller shows 'No SS'.
Hydrawise flow sensor that reports per-zone flow and sends high-flow, low-flow and leak alerts.
Specs: HC-075-FLOW 3/4" (0.22 min / 15 rec / 21 max GPM), HC-100-FLOW 1" (0.3/30/34), HC-150-FLOW 1 1/2" (0.88/66/88), HC-200-FLOW 2" (1.98/105/132); male NPT; 230 PSI max; analog dial in U.S. gallons; wired with shielded 18 AWG up to 1,000'; W-HC-FLOW wireless kit 900 MHz, 500' line of sight; works with HPC, Pro-HC, HCC (and ICC2 via Centralus); NOT X2/WAND; warranty 2 years
Tech note: Install between master valve and zone valves, horizontal, arrow with flow, with 10 pipe diameters straight before and 5 after (1" meter = 10" / 5"). Picking the wrong model size in the app causes false alerts. Slow-leak alert threshold is 8 GPM over an hour; high-flow leak recommended at 1-3 GPM.
Hunter Dripline (HDL) is the current pressure-compensating inline dripline, described by Hunter as the upgrade to PLD.
Specs: 0.4, 0.6 or 0.9 GPH emitters; 12", 18" or 24" spacing; 0.660" OD x 0.560" ID; PC, PC with check valve (CV) and reclaimed (R) versions; blank tubing; up to 60 PSI; 120 mesh (125 micron) filtration; coils 100', 250', 500', 1,000'; warranty 5 years plus 2 for environmental stress cracking
Tech note: Uses PLD-LOC or 17 mm barb fittings. PLD fittings themselves carry a 1-year warranty; dripline needs a filter and regulator (ACZ/PCZ zone kits are 2-year items).
Subsurface system of fleece-wrapped dripline (Eco-Wrap) bonded to a capillary fleece mat for turf, gardens and green roofs.
Specs: 0.6 GPH emitters at 12" spacing, laterals 14" apart, ~0.83 in/hr; 32" wide; 100' mini roll (~250 sq ft) or 295' standard roll (~737 sq ft); 15-50 PSI; 120 mesh; check height 6'; holds 0.5 gal per square yard; install 4"-6" under turf, 4"-14" elsewhere; air relief on slopes over 6'; warranty 5 years plus 2 for stress cracking
Tech note: Install with the dripline on top of the mat; not for large plants whose roots exceed 12".
Hunter's residential handheld remote that plugs into any SmartPort-equipped controller to run stations from the yard.
Specs: 1,000' line-of-sight range; 433 MHz; receiver 24 VAC 0.010 A; 128 programmable addresses; ROAM-KIT = transmitter, receiver, SmartPort harness, 4 AAA; compatible with X-Core, X2, Pro-C, HPC, ICC2, HCC, I-Core, MCC, ACC, ACC2; manual runs 1-90 minutes without changing programs; warranty 2 years
Tech note: Transmitter and receiver must share the same address; if the receiver does not beep when plugged in, check the SmartPort wiring (red/white/blue to AC1/AC2/REM).
Long-range commercial remotes; ROAM XL was discontinued in 2025 and replaced by ROAM LR.
Specs: ROAM XL: up to 2 miles line of sight, 27 MHz, up to 240 stations, 4 AAA, SmartPort max 50' from controller, warranty 3 years; ROAM LR: same 2-mile range, warranty 3 years
Tech note: ROAM LR transmitters do not work with ROAM XL receivers (different frequencies).
The white Hunter wrench (3/32 Allen key plus plastic arc key) adjusts every Hunter rotor; the MPTOOL adjusts MP Rotator arc and radius.
Specs: Hunter wrench: 3/32" hex for radius, plastic key for arc, finger loops; MPTOOL or small flat-blade screwdriver for MP radius screw
Tech note: A plain 3/32" Allen key does radius only; arc needs the Hunter key.
The symptoms we hear on the phone most, what is usually behind them, and how our technicians handle each one.
What we do: Pull the internal assembly, clean the filter, check pressure; if it still stalls, swap the head (PGP Ultra internals are not field-serviceable).
What we do: Find and repair the leak, replace the riser seal (kit P/N 253400 for PGP/PGP Ultra/I-20-12), or flush/replace the valve diaphragm.
What we do: Remove and rinse the screen, open radius 4 turns and cycle the arc ring to flush, then verify pressure with an MP gauge and correct supply or body (PRS40).
What we do: Convert heads to PRS30 (sprays) or PRS40 (MP Rotators) bodies or throttle the valve flow control.
What we do: Shut the water, disassemble and rinse the valve, replace a damaged diaphragm, snug the solenoid and bleed screw, confirm the flow arrow points to the heads.
What we do: Open the bleed screw to prove water, meter the terminals and the splice, swap wires with a working zone to isolate controller vs field, clear the port with 18 AWG wire or replace the solenoid.
What we do: Add check valves (HCV or CV bodies/rotors) for low-head drainage; service the valve if it never stops.
What we do: Swap the wire to a good terminal to confirm, ohm the solenoid (20-30 ohms), repair the splice or replace the solenoid, then press any button to clear.
What we do: Leave one start time per program and delete the rest; Hunter calls this the most common cause of repeats.
What we do: Remove the jumper, set Active, lower the Mini-Clik set point, relocate the sensor, resync or replace the wireless transmitter.
What we do: Power-cycle, run Status > Connection Status > Check Connection, re-enter credentials on a 2.4 GHz SSID, add an extender, or factory-reset and re-add; keep an on-site rain sensor so the system still shuts off without internet.
What we do: Restore power, meter the transformer for 24-28 VAC, replace the transformer or panel; surge/lightning damage is excluded from Hunter's warranty.
What we do: Raise/lower Water Adjustment 1-10, step the Region up or down and restart at 5, or move the sensor into full sun; the Bypass switch does not stop the seasonal adjust.
What the display or app is telling you, and what it takes to clear it.
| Controller | Message | Meaning | Usual cause | What our tech does |
|---|---|---|---|---|
| Pro-C / X-Core / ICC2 / P2C | # ERR (e.g. 1 ERR) | Fault detected on that station's output (short-circuit protection tripped). | Shorted or nicked field wire, bad splice at the valve, or a failed solenoid on the station shown. | Press any button to clear, swap the faulting wire into a known-good terminal to confirm it is the field side, then ohm the circuit (solenoid should read 20-30 ohms), fix the splice or replace the solenoid. |
| Pro-C / X-Core / ICC2 / P2C | P ERR | The pump/master-valve (P/MV) circuit is drawing too much current. | Defective master-valve solenoid, incompatible or failed pump start relay, undersized or too-long wire to the relay. | Check for 24-28 VAC at the relay or MV, ohm the MV solenoid (20-30 ohms), verify relay specs do not exceed the controller's P/MV rating (0.28 A on Pro-C/X-Core/X2, 0.56 A on ICC2/HCC), repair wiring or replace relay/solenoid. |
| Pro-C / X-Core / ICC2 / P2C | SP ERR or ERR (no number) | SmartPort error: noise or miswiring on the remote-control port. | SmartPort harness bundled with field wires, wires on the wrong terminals (white next to blue on REM, red above ground), damaged harness, or a remote receiver set to the wrong station count. | Re-route the harness away from field wiring, correct the terminals, check the remote's max station setting, replace the SmartPort harness or receiver if the error stays. |
| Pro-C / X-Core / ICC2 / P2C | NO AC (or blank display) | Controller has lost 24 VAC and is running on the 9 V backup battery (time only, no watering). | Dead outlet, tripped GFI/breaker, failed transformer, loose AC terminal; a hardwired outdoor unit needs an electrician for the primary side. | Verify the outlet with a lamp, meter the transformer for 24-28 VAC at the AC terminals, replace the transformer (X-Core indoor P/N 526500, outdoor 468000) or, after a 4-5 minute power cycle still shows nothing, replace the panel/controller. |
| X-Core / P2C (Pro-C) | No SS | A Solar Sync sensor that was installed is no longer detected. | Solar Sync removed without uninstalling it, broken sensor wire, loose SEN terminals. | Re-land the sensor wires on SEN, or if it was removed on purpose press the reset button on the back of the panel (P2C) or turn to the Solar Sync position until dashes show (X-Core) to uninstall it. |
| X-Core / Pro-C with Solar Sync | Dashes at the Solar Sync dial position | No Solar Sync is connected, so there is no Region or Water Adjustment to show. | Sensor not wired, wire break or bad connection. | Connect the sensor to SEN, check the wire run, reset the controller; the display then shows Region and Water Adjustment. |
| ICC2 | E99 ERR | Internal circuit-board fault in the front panel. | Failed facepack electronics (often after a surge). | Replace the ICC2 front panel; station modules and cabinet stay. |
| ICC2 / X-Core | Frozen or garbled display | Processor glitch, usually after a power surge. | Lightning or line surge, electrical anomaly. | Reset the controller (Pro-C: hold PRG and press RESET until 12:00 am; X-Core: hold the three buttons and press RESET until DONE), then reprogram or restore with Easy Retrieve. |
| X-Core | Umbrella icon / flashing sprinkler icon with no zones running | Umbrella = rain sensor is holding irrigation off or the SEN jumper is missing; flashing sprinkler with no water = the controller thinks it is watering but nothing is running. | Wet sensor or missing jumper; water supply off, wiring short, or bad solenoid. | Slide the rain-sensor switch to BYPASS to test or install the jumper; for the flashing icon check the backflow/supply, field wiring and solenoids. |
| X2 with WAND | FAIL / bAd SSID OR PASS CodE / rouTer CONNECT FAIL / Cloud CONNECT FAIL / OFF LINE | Wi-Fi setup failed; wrong network name or password; cannot reach the router; cannot reach the Hydrawise server; was connected but Wi-Fi dropped or went out of range. | Typo in SSID/password, 5 GHz-only network, weak signal, ISP/DNS or certificate problem. | Confirm a 2.4 GHz network and re-enter credentials, move the router or add an extender, power-cycle (unplug 10 s), run Bluetooth Diagnostics in the Hydrawise app, and if needed hold the WAND button 5 s until 'Fdr' shows to factory-reset and re-pair. |
| Hydrawise (Pro-HC / HPC / HCC) | High Current (overcurrent) alert | The built-in milliamp sensor saw too much current on a zone and shut it off. | Wiring short or bad solenoid; thresholds are PHC 850 mA, HPC 900 mA, HCC 1,200 mA (a normal solenoid draws 200-400 mA, 300-500 mA with a master valve). Not available on the old HC. | Pull that zone wire (and the P/MV wire if all zones alert), run the zone manually, inspect the splice for corrosion, test the solenoid wired straight to the controller, replace the solenoid or repair the wire. |
| Hydrawise (Pro-HC / HPC / HCC) | Low Current alert | Current on the zone measured 0-70 mA, i.e. an open circuit; alert arrives after the cycle ends. | Broken wire, failed solenoid, or a non-Hunter solenoid/low-voltage lighting relay; a PXSYNC lighting transformer (34-39 mA) also triggers it. | Run the zone manually; if no water, trace the common and zone wire, test the solenoid directly on the terminals, replace the solenoid or repair the open. |
| Hydrawise touchscreen (HC / Pro-HC / HPC) Check Connection | Enable Wi-Fi / Wi-Fi 2.4gHz / Move Router Closer / Check DNS / NTP Fail / IOT Fail / HTTPS Fail | Controller is in Offline Mode; no 2.4 GHz network found; weak signal; ISP or router DNS problem; NTP blocked; TCP port 8883 blocked; HTTPS blocked. | Offline programming left on, 5 GHz-only router, distance/walls, router filtering or parental controls. | Re-enable Wi-Fi under Offline Programs and Settings, confirm a 2.4 GHz SSID and WPA2 password of 8+ characters, add a repeater, and have the customer's ISP/router open DNS, NTP, TCP 8883 and HTTPS. |

How to read the markings on your equipment, and Hunter’s published warranty terms for reference.
Factory warranty claims go through the dealer or distributor the product came from, not through Aqua Premier. Everything we supply and install carries our own 2-year parts-and-labor warranty.
Specifications, procedures and warranty terms above are summarized from Hunter’s published product pages, manuals and support site and may change; always confirm against the current Hunter documentation for your exact model. Hunter is a trademark of its owner; Aqua Premier is an independent contractor and is not affiliated with or authorized by Hunter.
Yes. Aqua Premier is a family-owned irrigation company based in Ponte Vedra with its shop in Nocatee, and Hunter equipment is part of our everyday work across St. Johns and Duval County.
Yes. If a Hunter part is discontinued or a different product fits your yard better, we’ll say so and give you an up-front quote either way — our 2-year warranty covers the parts we supply and our labor.
Yes. We work on Hunter equipment on homes, HOA common areas, office parks, churches and other commercial properties across St. Johns and Duval County — the same licensed crew, with an up-front written quote either way.

Hold the turret at the right stop and turn the plastic key of the Hunter wrench in the top socket: clockwise widens, counterclockwise narrows, 90 degrees per turn (50-360 on PGP Ultra, 40-360 on older PGP). The 3/32 hex end in the radius screw shortens the throw up to 25%. Aqua Premier adjusts arcs and radii on every head during a tune-up.
Hunter says the most common cause is debris in the filter at the base of the riser; low pressure and a contaminated gear drive are next. Cleaning the filter is the first step, and a rotor that still won't turn is replaced. Aqua Premier cleans or swaps stuck PGP, PGJ and I-20 rotors.
A station number plus ERR means the controller found a short on that zone's wire or solenoid; P ERR is the pump/master-valve circuit; SP ERR is the SmartPort remote wiring. Pressing any button clears the message but the short stays. Aqua Premier traces the wire and replaces the solenoid or splice.
The controller has lost 24 VAC and is only keeping time on its 9 V battery; it will not water. The outlet, GFI or the transformer (which should put out 24-28 VAC) is the usual culprit. Aqua Premier tests the transformer and replaces it or the controller.
Hold the PRG button, press and release RESET on the back of the face panel, and let go when 12:00 am appears; the X-Core uses its three front buttons plus the side RESET. Programs saved with Easy Retrieve survive the reset. Aqua Premier can reset and reprogram the controller for your yard.
With the zone running, turn the arc ring clockwise to widen or counterclockwise to narrow; turn the center screw clockwise (up to four turns) to shorten the radius. MP Rotators are designed for 40 PSI and reach minimum radius at 30 PSI. Aqua Premier dials in MPs and installs PRS40 bodies where pressure is too high.
Yes, MP Rotators thread onto any Pro-Spray body, but Hunter recommends converting the whole zone and running it longer because the 0.4 in/hr rate is much lower than sprays. Over 55 PSI the warranty is void, so a PRS40 regulated body is the right pairing. Aqua Premier converts spray zones to MP Rotators.
Debris caught between the diaphragm and seat is the top reason a PGV weeps or won't close; a torn diaphragm, a solenoid left open, or pressure under 20 PSI are others. Water that stops after a minute is low-head drainage, fixed with check valves, not the valve. Aqua Premier cleans or rebuilds the valve and adds check valves where needed.
Most often the jumper on the SEN terminals was never removed, the bypass switch is on, or not enough rain reached the sensor. Test it during a Manual All Stations run by pressing the spindle; a single-station run ignores the sensor. Aqua Premier tests and replaces Mini-Clik and Rain-Clik sensors.
Hydrawise needs a 2.4 GHz Wi-Fi network with a WPA2 password of at least 8 characters, a usable signal, and an ISP that is not blocking DNS, NTP or TCP port 8883; the controller's Check Connection screen reports which one failed. A power cycle is Hunter's first fix. Aqua Premier reconnects Pro-HC, HPC, HCC and X2/WAND controllers.
A PC-400 dated March 2014 or later, or a P2C-400, accepts the HPC-FP Hydrawise face panel; the older PC-300 cannot be upgraded. Hunter also sells the PC-WIFI module for Centralus on the P2C-400. Aqua Premier installs the upgrade panel and sets up the app.
Hunter's limited warranty runs from the date of manufacture: 5 years on PGP Ultra, I-20, Pro-Spray bodies, ICV, Clik sensors and Solar Sync; 3 years on MP Rotators; 2 years on PGV valves, X-Core, X2, Pro-C and Hydrawise controllers; 1 year on the SRM. It covers parts only, excludes lightning and surges, and goes through an authorized distributor for the original installer; retail or Amazon purchases are not eligible. Factory claims go through a Hunter distributor and cover parts only; anything Aqua Premier supplies and installs is covered by our own 2-year parts-and-labor warranty.
Both throw 17-46 feet with the same nozzles, but the I-20's rubber cover has a FloStop hole in the center and ships with a check valve; purple covers mean reclaimed water. The PGJ and SRM are the smaller 1/2-inch rotors and the I-25 is the 1-inch large-turf model. Aqua Premier identifies and matches replacement heads on site.
Shut off the water, unscrew the old solenoid counterclockwise, thread on the new 24 VAC Hunter solenoid hand-tight, and reconnect the two wires with waterproof splices; battery controllers need the DC-latching solenoid instead. A good solenoid reads 20-30 ohms. Aqua Premier replaces Hunter solenoids and diaphragms as part of a valve repair.
The sensor sets Seasonal Adjust every night from sunlight and temperature; you tune it with Region 1-4 and Water Adjustment 1-10 at the Solar Sync dial position. The Bypass switch only disables the rain/freeze shutoff, and a sensor must be uninstalled at the dial or the controller shows No SS. Aqua Premier installs and calibrates Solar Sync for North Florida.
OFF LINE means the WAND had Wi-Fi but lost it; FAIL or bAd SSID/PASS means the network name or password was wrong; rouTer CONNECT FAIL usually means the network is not 2.4 GHz. Holding the WAND button 5 seconds until Fdr shows factory-resets it. Aqua Premier re-pairs WAND modules and restores Hydrawise schedules.
