You can define tailored programs for turf, shrubs, and drip lines so each zone gets exactly the attention it needs. You’ll save water and improve plant health by assigning different run times and frequencies appropriate to each irrigation type.
Seasonal adjustments and temporary overrides
Seasonal adjustments let you increase or decrease run times by percentage, which is handy as water needs change throughout the year. You’ll also have quick-access temporary overrides for one-off events, such as extra watering during a heatwave or pausing irrigation during heavy rain.
Smart watering mechanics
Understanding how the HRC 400 decides to water will help you make better configuration choices. You’ll be able to provide accurate inputs and trust the controller’s calculations to reflect actual site conditions.
Using slope, soil type, and sun/shade inputs
When you tell the controller about your slope, soil type, and sun/shade exposure, it adjusts run time and frequency to match infiltration rates and evapotranspiration. You’ll want to be honest with these inputs because they directly affect how much water is delivered to each zone.
Historical ET and live weather feeds
The controller uses historical evapotranspiration patterns and live weather data to adjust irrigation on the fly, compensating for recent rain or high temperatures. You’ll benefit most if the unit can reliably access accurate local weather data, so positioning and Wi‑Fi quality matter.
Rain delay and sensor features
Rain delay options give you granular control over pausing irrigation when rain has occurred or is forecast. You’ll find this especially useful during the rainy season or during events when municipal watering restrictions are in effect.
Manual and automatic rain delay
You can manually set delays for short or long periods, or configure the controller to automatically apply a delay when connected sensors or weather conditions indicate sufficient moisture.
