Intermatic DDT40 Complete Adaptive Defrost Refrigeration Time Control with ICUBE™ Module, Sensor, and Type 3R Enclosure
For electric heat, hot gas or compressor shutdown defrost. The DTAV40 Series Auto Voltage Defrost Timer is applicable to air defrost (compressor shutdown) and electric or hot gas defrost systems where the defrost cycle is terminated by the timer. If the coil is frost-free, the timer can also be terminated by temperature or pressure switches before the programmed defrost termination time has been reached. The time termination functions as a fail-safe and terminates the defrost cycle if the temperature or pressure switch fails to do so.
Features:
- Improved relay performance
- 1 evaporator sensor included, expandable up to four sensors (178GR10K-1)
- Comes with 10' sensor wire with thermistor and 6' input wire
- Sensor wiring can be expanded up to 400' through existing conduits to reach remote condensing units
- Initiates defrost only when necessary at next timer-programmed interval
- Temperature initiated (with time delay), temperature, pressure or time terminate
- Moisture resistant conformal-coated board
- LED indicators for defrost and refrigeration cycles
- Defrost cycles are programmed independently
- Real-time clock face for quick, easy and accurate setting
