The SC 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 SC 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 SC 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.
Features
- Sensor-controlled mode - saves water and automatically adjusts to weather conditions
- Supports up to 24 soil moisture sensors
- Sensor sharing allows multiple zones to be controlled by a single sensor
- Soil moisture sensor thresholds can be set from 1-99% water content per unit volume
- Easy sensor installation using existing valve wiring
- Uses conventional valve wiring. (One wire per valve + common)
- Watering day schedules include Custom, Every Day, Odd Day, Even Day, and Every Nth Day watering (where N may range from 2 to 31)
- Zone stacking ensures all zones will eventually be watered even if program start times overlap
- Programmable valve delay allows slow-closing valves time to turn off completely
- Valve test mode rapidly checks the valve current of each zone on the system
- Cycle + Soak feature prevents water runoff by watering in short bursts
- Define up to 6 pause events
- Water up to 4 zones simultaneously
- Seasonal water budget for timed zones
- Optional flow meter interface available
- Configuration information is preserved even if power and batteries fail
Operating Specs
- 6 programmable pause events
- Four independent timed programs each having six start times with 1 minute increments
- Each soil moisture sensor added to the system adds a sensor program with 6 start times each (up to 40 programs)
- Supports rain/wind/freeze sensor inputs
- Flow meter support monitors water use and pipe condition
- Water up to 4 zones simultaneously
- Adjustable multi-zone watering to prevent loss of water pressure
- Walk-around test mode operates each zone for a programmable length of time
- Pause mode suspends controller operation
- Optional recover watering after power failure
- Water Budget is programmable between 5-500% per month for timed programs
- Programmable Rain delay from 0-14 days for timed programs
- Zone run-time can be set from 0-18 hours in 1-minute increments
- Manual zone start and manual program start
- Master valve terminal always operates for each zone
- Separate pump start terminal is programmable by zone
- Adaptable to the TRC Commander radio and EICON radio though a separate DCI adapter
- Automatically compensates for leap years
Electrical Specs
- Input: 115 VAC +/- 10%, 60Hz
