Hunter PC-400 4 Station Outdoor Modular Sprinkler Timer

  • Hunter Pro-C Modular Indoor/Outdoor Controller
  • 4 Stations
  • Modular Controller


Features & Benefits

The Pro-C has proven to be the most reliable and robust controller in the industry, with the flexibility to expand on demand due to its modular design. When expansion isn't necessary, the fixed 6 and 12 station models offer affordability in a high-end residential controller. Now, the Pro-C will easily accommodate Hunters Solar Sync without additional wiring. The new Solar Sync dial position makes it easy to upgrade and program any Pro-C to smart control. The Hunter Solar Sync is an EPA WaterSense labeled smart device which calculates evapotranspiration (ET) and adjusts Hunter controllers daily based on local weather conditions, resulting in water savings and conservation. The Pro-C and all AC powered Hunter controllers are now EPA WaterSense labeled when paired with the Solar Sync weather sensor.

Advanced Features

WATERSENSE® SMART WATERING CONTROLLER BY ADDING SOLAR SYNC

By adding a Solar Sync™ to your Hunter controller, it transforms into a smart controller using local weather conditions to tailor watering schedules to actual conditions on the site. A Hunter controller with Solar Sync has been independently proven to have a detailed list of water saving features and has been approved by the EPA as a WaterSense Smart Watering Controller. Click here to learn more about Smart Controllers

EASY RETRIEVE™ MEMORY

A manual back-up utility that stores complete controller scheduling and setup information in back-up memory. This allows the saved watering schedule to be restored at any time. This can be used to set a controller back to its initial settings after tampering or at the beginning of a new season.

AUTOMATIC SHORT CIRCUIT PROTECTION

Automatic short circuit protection is a feature found in all Hunter AC powered controllers. This feature automatically detects electrical faults, which are typically caused by wiring issues. Only affected stations are skipped, allowing all other stations to water normally as programmed. There are no fuses to blow or internal circuit breakers to trip, so complete irrigation system shutdown is avoided.

QUICK CHECK™

The QuickCheck feature makes field wiring issues easy to assess with the push of a button. QuickCheck displays an ERR message when a field wiring short is detected on a particular station number.

SEASONAL ADJUSTMENT: GLOBAL OR AUTOMATIC UPDATES WITH SOLAR SYNC

This feature allows for quick adjustments to irrigation run times through a percentage scale. During peak season, set the seasonal adjustment to 100%. If weather conditions require less water, enter the appropriate percentage value (i.e. 50%) to cut down irrigation run times without the need to adjust each station in the program. This model offers two different ways to use Seasonal Adjustment to reduce water usage: Global and Daily.

Global: The Global option provides a Seasonal Adjustment percentage to all station Run Times on all of the controller's Programs.

Daily: With the addition of a Solar Sync ET Sensor, the controller has the ability to automatically implement daily adjustments based on measured local weather.

DELAY BETWEEN STATIONS

Users can program a delay between stations as the controller advances from one station to the next. This delay can range from a few seconds (to permit slow-closing valves additional time to close) to a much longer period of time (to allow pressure tanks time to recharge), based on user requirements.

SENSOR PROGRAMMABILITY

The ability to specify which program will be shut down in response to a specific sensor alarm. This allows programs unaffected by the sensor to continue automatic operations.

NON-WATER DAYS

Day(s) of the week can be programmed OFF in advance, so that irrigation does not occur regardless of program interval schedules. For example, if the gardener mows the lawn on Saturday, the Non-Water Days feature allows Saturday to be programmed OFF, so that watering will not occur.

Hunter Pro-C Modular 4 Station Indoor Controller

Installing Station Modules: (Sold Separately)

The Pro-C controller is supplied with a factory-installed base module for up to 4 stations. Additional modules may be added in increments of 3 stations (PCM-300) or a single 9-station (PCM-900) to expand the controller’s station capability to 16 stations. Additional modules are sold separately.

The Pro-C utilizes automatic module recognition firmware to identify when PCM modules are installed or removed from the controller. This feature will recognize the correct number of stations without having to reset or cycle power to the controller

Installing PCM Modules

The Pro-C controller is designed with a simple to use "Power Lock" feature that assures that the modules are energized and firmly secured into the controller. The "Power Lock" can unlock or lock all modules at one time by simply pushing the "Power Lock" slide.

  1. Slide the "Power Lock" into the "Power Off" (unlocked) position. Insert the PCM modules into the appropriate sequential position in the controller cabinet.
  2. Once all of the modules are in place, slide the "Power Lock" into the "Power On" (locked) position to energize and secure the modules into the controller.
  3. The Pro-C will automatically recognize the correct number of stations. It is not necessary to press the reset button or cycle power to the controller.
Hunter Pro-C Modular 4 Station Indoor Controller

Note:The use of a PCM-900 to expand your controller to 16 stations requires that one PCM-300 be installed in the first expansion slot (stations 5–7) and the PCM-900 in the upper two expansion slots.

Great Reliable Timer
I used the PC-400 to replace a defective 300. Every component fit and it was an easy swap out. The only problem I experienced was the common wire for the zones was attached to the common terminal on the relay modular. The 400 common, although clearly marked, is not mentioned in the instructions. There should be a note to use this common on a swap-out instead of the one on the module. A little set back, but all working now...

Good solid product .
I left the weather door ajar and a rainstorm blew it open. That was the end of the electronics but the front panel is available and easy to replace. That saved rewiring the whole unit. The relays survived.

Fit my unusual need
I have a U-Pick vineyard and needed a timer that could be programed to alternate between two master valves for a specific length of time all night long (15 min for section 1, turn off, switch to section 2 and turn on for 15 min and then back to sector 1, repeat all night long). This was to help prevent freezing of the vines during early and late season cold snaps. There is a feature called"Cycle and Soak" and is exactly what I needed. Thanks to Sprinkler Warehouse and Hunter for all their help in getting it programed and working.

Make sure you have a power cable
The controller is fine. Make sure you have a power cable. This unit does not come with one. If you are replacing a controller, you can use the old cable.

My house's sprinkler system was cracked and filling up the manifold pit with water. Someone used an inferior system. I got the info from chat on sprinklerwarehouse 2 years ago and could not have been happier. This timer was matched perfectly to the new manifold I ordered at the same time. Saved me $2500 for new system installation.

Hunter Pro-C Modular 4 Station Indoor/Outdoor Controller | PC-400
Hunter X-CORE 4 Station Indoor Controller | XC-400i
Hunter X-CORE 4 Station Indoor Controller | XC-400i
BEST ANSWER: It's the same unit same features outdoor just has a protective lock box.
Is this unit expandable to 15 stations?
Dr. Vinny G on Dec 24, 2014
BEST ANSWER: Yes. By installing one PCM-900 and one PCM-300 you are able to increase service from 4 up to 16 stations. In your case you would have one zone left unwired and available for future use. The expansion modules are very easy to install by simply moving the expansion lock master slide bar to the POWER OFF position, sliding in the expansion modules and returning the master slide bar to the POWER ON position.

Hunter PC-300 3 Station Modular Outdoor Sprinkler Timer
BEST ANSWER: Yes. This is the replacement for the PC-300 and also replaces the need to add the Solar Sync Sensor MODULE as this is now incorporated as a rotary dial position on the PC-400. Only the Solar Sync sensor is required to add the automatic features to the PC-400.
does manual start automatically run all stations?
John M on Apr 11, 2016
BEST ANSWER: Most hunter clocks have a manual start single station and a manual start all stations which will cycle through all stations from the start station to end depending on program selected.
is the 24 volt transformer included in the controller?
Rick E on Nov 18, 2017
BEST ANSWER: Yes. I use these very same controllers on a golf course.
Can this be used with the rainbird DFV-100 valve?
David D on Apr 2, 2017
BEST ANSWER: This is a standard 24AC selenoid valve. The Hunter controller should have no problems providing the rush- and holding currents for this valve
On a PC-400, if I turn the knob from run (at an idle time) to the manual position and then back to the run position------will the controller run all stations as programed?
John M on Apr 12, 2016
BEST ANSWER: I am not fully understanding the question.
If you change from run to manual and then back to run the system will the only run as you had originally programmed it, You do not loose the programming set by changing to manual.ten to run
You can run the system manually for example if you wanted to trouble shoot a problem or water between scheduled cycles.

Easy to run and understand how to operate
Highly recommend this unit
Can the buil- in transformer on the outdoor controller be replaced?
Bob M on Feb 28, 2017
BEST ANSWER: Yes. A replacement transformer is listed on the Sprinkler Warehouse website as a Hunter Pro C Transformer Out Door. This is a 120v, 24 Vac transformer that will fit a Hunter PC-400 4 Station Outdoor Modular Sprinkler Timer.

does the hunter pc-400 i ( indoor) have a case enclosure to conceal the electronics?
A shopper on Jul 23, 2015
BEST ANSWER: I bought the outdoor version
I believe the only difference between the two is
The indoor has an external transformer
That needs to be plugged in inside the house and run a low voltage wire to the controller
The outdoor version takes 110 volts directly into the controller
The transformer is built inside the controller
All controls are sealed from the weather inside a weather tight box with a lock and key
Excellent unit 5 stars
How do you tell the indoor from the outdoor controller?
vince s on Jan 31, 2015
BEST ANSWER: The indoor controller comes with a plug-in transformer and pigtail for low voltage wiring. The outdoor controller has a built in transformer to convert the 110v supply wiring. The second photo for either model shown online incorrectly reflects the indoor controller for both. With the wiring access panel open, the outdoor controller has a screw mounted cover over the lower left open compartment and a 5/8" threaded access port to receive the 110v supply conduit. Otherwise, the two look identical in appearance with the exterior cover door off and the wiring access panel closed.
i need 240 volt system, do you have one?
caesar a on Apr 13, 2018

how do i know if i have a pro-c 400 or pro-c 300 ?
A shopper on Jun 20, 2016
BEST ANSWER: Open the control panel face plate and it's marked on the inside of the controller door. The face plate is on hinges, apply slight pressure on plastic lock seat and the door should swing open.
How do you program the days you want to water?
A shopper on Jul 30, 2015
BEST ANSWER: you go to the watering days then you press the plus symbol to turn them either on or off and then you go right or left with your arrows to go to the next watering day
The controller data implies that rain gauging is incorporated. Is this per pro c 400 or per pro c station timing?
Dr. Vinny G on Dec 24, 2014
BEST ANSWER: The Solar Sync sensor or Rain click sensor accessory options have moisture saturation fiber disks that supply the timer with the electronic information of being either wet or dry.
on a Hunter x-core timer how do you start a single station watering ?
A shopper on Dec 10, 2014
BEST ANSWER: I have a pro-c controller but imagine it would be the same on the x-core. For manual watering turn dial to manual and select station and duration, then turn dial to run.

If this does not work, manual watering is usually explained in the user manual.
