Hunter PC-400 4 Station Outdoor Modular Sprinkler Timer

The Pro-C controller was first introduced to the market in 2001, changing the way contractors and home owners alike think about sprinkler controllers. Its ability to expand to meet the needs of any application along with its affordable price made it the optimal choice for most residential and light commercial applications. No other controller on the market has proven to have the same tradition of dependability and reliability, making the Pro-C series of controllers a recognized industry leader.

The new generation of Pro-C controllers are now labeled as an EPA WaterSense® smart device*. They are capable of calculating Evapotranspiration (ET) automatically and adjusting the watering programs daily to save and conserve water. The new Pro-C controller now seamlessly interfaces with the Hunter Solar Sync® using the included dial settings making it easy to manage your irrigation responsibly. includes additional new features but has been developed and built upon the solid foundation of previous Pro-C models.

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.


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 is a feature found in all Hunter AC powered controllers. This feature automatically detects electrical faults, which are typically caused by wiring issues. Stations that have shorts detected are skipped, allowing watering to continue for those stations where faults are not detected. There are no fuses to blow or internal circuit breakers to trip, so complete irrigation system shutdown is avoided.


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

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.


A delay in watering between individual stations as the controller moves from one to the next. The delay may range from a few seconds, to permit slow-closing valves time to shut down, or much longer to allow pressure tanks, etc., to refill or recharge.


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


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.
