SC24/36

Suspended Cycle® Irrigation Controller

The SC24/36 controller incorporates cutting edge moisture sensing technology to prevent over-watering. The SC Series employs Acclima Digital TDT® moisture sensors with many easy-to-use features for optimum irrigation efficiency.

The controller operates based on soil moisture measures by Digital TDT® moisture sensors. Programs are set similar to traditional timers; however, the SC Series only waters if the moisture level is below your "turn on" threshold. Each zone can be set to one of two modes of operation: as a sensor controlled zone, or as a timed zone. The SC24.36 easily accommodates both drip zones and spray zones.

Features:

• Sensor-mode operation saves water and adjusts to weather conditions
• Non-volatile program memory
• Easy installation of sensors using existing valve wiring
• Conventional wiring of valves. (One wire per valve + common wire)
• Supports 0 to 24/36 soil moisture sensors with sensor sharing
• Watering day schedules include Custom, Every Day, Odd Day, Even Day, and Every Nth Day watering (where N rages from 2 to 31)
• Zone stacking ensures all zones will eventually be watered though program start times may overlap
• Soil moisture sensor thresholds can be set from 1% to 99% water content per unit volume
• Programmable valve delay allows slow-closing valves time to turn off completely
• Valve test mode rapidly checks the valve current of all zones
• Cycle + Soak feature prevents runoff by putting down water in short bursts
• Flexible, programmable manual programs
• Pause mode suspends controller operation
• Multiple zone watering (1-4) simultaneously
• Seasonal water budget for timed zones
• Optional flow meter interface available

Operating Specifications:

• Six programmable pause events
• Calendar/clock compensates for leap years
• Four independent timed programs with six start time each. Start time resolution one minute
• Each soil moisture sensor added to the system also adds a sensor program to the system with six start times each (up to 40 programs are possible in total)
• Supports rain/freeze/etc. sensor inputs
• Flow meter support monitors water use and pipe conditions
• Multi-zone watering up to four zones simultaneously
• Multi-zone watering may be adjusted to prevent loss of water pressure
• Walk-around test mode operates each zone for a programmable amount of time
• Pause mode suspends controller operation
• Optional recover watering after power failure
• Programmable Water Budget between 5-500% per month for timer programs
• Programmable rain delay from 0-14 days for timed programs
• Zone run times set from 0 to 18 hours in 1-minute increments
• Manual zones start and manual program start
• Master valve terminal always operates for each zone
• Separate pump start terminal is programmable by zone
• Adaptable to the TC Commander radio, and EICON radio through a separate DCI adapter
