The SC36i is a 36 zone controller that incorporates cutting edge moisture sensing technology to prevent over-watering. It employs Acclima Digital TDT® moisture sensors with many easy-to-use features for optimum irrigation efficiency.

Using Acclima Digital TDT® moisture sensors, the SC36i measures the amount of moisture in the soil and suspends watering if the soil is sufficiently wet. It can set, maintain and monitor any desired moisture level. Watering programs are defined similar to traditional timers; however the SC36i only waters if the soil needs it. During the hottest part of the year, soil moisture is depleted more rapidly and the system will water more frequently. When the temperature cools, or a rainstorm occurs, the system will inhibit watering until the moisture level in the ground falls below the "turn on" threshold.

Each of the 36 zones can be set to one of two modes of operation: as a sensor controlled zone as described above, or as a traditional timed zone. The SC36i can water multiple zones simultaneously and easily accommodates both drip and spray zones. You can even optimize your water source usage with Acclima's intelligent flow control.
