Product Specification Features
DXM Electronic Heat Pump Control
The DXM electronic control is a robust, microprocessor based heat pump controller that is advanced and feature-laden for maximum application flexibility. The DXM Control has all of the basic CXM control features plus additional inputs and outputs which allow for extensive system capability. The DXM Control has relay outputs for Compressor, Fan, Fan Speed, Reversing V alve, Alarm Relay, and 2 configurable accessory outputs. There are 3 LED’s which provide status indication.
There are inputs for safety pressure switches, low temperature protection thermistors, condensate overflow sensor, DIP switch selection inputs, thermostat inputs, night setback inputs, and emergency shutdown input. There are also 2 communications ports: one for communications with DXM dual compressor heat pumps, and another for communications with DXM slaved heat pumps.
