The CS3500 is the most efficient irrigation controller on the market. Using Acclima Digital TDT® soil moisture sensors and Water on Demand® technology, the CS3500 can set, maintain and monitor any desired moisture level. Once moisture levels are defined, the controller automatically adjusts watering for changes in soil water content. During the hottest part of the year, the controller might water every day. When the temperature cools, or rainfall occurs, the controller prevents zones from watering until the moisture level in the soil falls below the defined moisture level. With moisture sensors determining when to water, the controller waters the zones only when they need water.
Each zone can be set to one of three modes:
- Reference - Using its own moisture sensor
- Dependent - Tracking a reference zone
- Timed - Using a traditional timer approach
The CS3500 easily accommodates both drip and spray zones and can water multiple zones simultaneously and Acclima's flow control optimizes the water use.
Features
