The Hunter® Pro-C® P2C-400 is the step-up from a basic residential timer — same simple dial-and-button programming as the X-Core, but with a modular wiring bay that grows from 4 stations to 23 as the property grows. Plus two sensor inputs, an optional Wi-Fi module slot for app control, dedicated Solar Sync programming, IP44 outdoor-rated cabinet, and 120 VAC plug-in install — this is the controller pros stock when they need one box that handles a starter system today and a full property tomorrow.

Why Pros Specify the Pro-C

• 4-station base, modular expansion to 23 stations — add PCM-300 (3-station) or PCM-900 (9-station) modules in the wiring bay; no controller swap, no wire pull
• Hybrid EZ Decoder option up to 32 total stations — mix conventional + two-wire on the same controller (28 stations max if two-wire only)
• 3 independent programs, 4 start times each — turf, drip, ornamentals, and a hand-water override on one controller
• 2 sensor inputs (SEN-1 / SEN-2) — wire a Hunter Clik rain/freeze/wind sensor and a separate Solar Sync ET sensor simultaneously, no jumper acrobatics
• Dedicated Solar Sync® dial position — full ET-based weather adjustment built into the firmware; pair with Solar Sync transmitter (sold separately) to take over seasonal adjust
• Optional PC-WIFI module — drops into the controller slot to enable remote programming and monitoring via the Hydrawise™ app over 2.4 GHz Wi-Fi (WPA/WPA2 personal)
• SmartPort® remote harness — included; plug in any Hunter ROAM or ROAM XL for one-person zone testing
• Optional Seconds Mode — run times in 1-second increments for high-precision drip / micro-spray zones
• Large backlit LCD — programmable in any light, including outdoor twilight installs
• P/MV output for pump start relay or master valve — standard on every Pro-C, no module add-on
• Built-in surge protection & non-volatile memory — programs survive power loss indefinitely
• Pre-wired 120 VAC cord with U.S. plug — outlet install, no electrician needed for residential outdoor mounts
• IP44 cabinet rating — certified for outdoor wall mount on a stucco, brick, or wood substrate
• 2-year manufacturer warranty, UL Listed

Where It Shines

• Residential properties starting at 4–6 zones with planned future expansion (back yard build-out, drip retrofit, lighting circuit add)
• Light-commercial sites (HOAs, small commercial frontage, restaurants) where 6–23 stations fit on one cabinet
• Service-call swaps replacing Hunter SRC, Rain Bird ESP-RZX, Orbit B-hyve, or Toro EVOLUTION — same SENS terminal, same pre-wired transformer install, faster pull-and-replace
• Anyone who wants the Wi-Fi upgrade path without paying for a Hydrawise-only controller today — buy the Pro-C now, drop in the PC-WIFI module when ready
• Mixed indoor/outdoor installs — the IP44 cabinet handles eaves, soffits, garage exterior walls without a separate enclosure

Install Notes

Mount location: indoor or outdoor (IP44 rated). Typical installs: garage exterior wall, mechanical room, eave under cover, or interior utility closet. Mount with the included screws on stucco, brick, drywall, or wood.

Power: 120 VAC convenience outlet within reach of the pre-wired transformer cord. No hardwiring required for the base unit.

Valve wiring: 18 AWG multi-strand sprinkler wire from the valve box, common to the C terminal, station leads to stations 1–4.

Expansion: rotate the locking lever on the wiring bay to POWER OFF, slide in the PCM-300 (3-station) or PCM-900 (9-station) module, rotate back to POWER ON. Stations become live immediately, no reprogramming.

Sensors: wire each Hunter Clik sensor to SEN-1 or SEN-2 with the bypass switch in ACTIVE.

Wi-Fi (optional): Power off, slide the PC-WIFI module into the dedicated slot, restore power. Pair to your 2.4 GHz network via the Hydrawise app.
