DXM2 Controls

DXM2 Control

DXM2 is the next generation in controls is capable of 2-way communication between itself and smart components, like the communicating thermostat, fan motor and configuration/ diagnostic tool.

For most residential applications, configuration, monitoring and diagnostics can be done from the thermostat / service tool and there’s no need to read LEDs and change DIP switches.

For details on user settings, refer to User Manual (part #:

For details on Installer settings (not to be used by consumers), refer to Installer manual (part #:

For details on installer/service settings on the configuration/ diagnostic tool, refer to operation manual (part #:

DXM2 Control Start-up Operation

The control will not operate until all inputs and safety controls are checked for normal conditions. The compressor will have a 5 minute anti-short cycle delay at power-up. The first time after power-up that there is a call for compressor, the compressor will follow a 5 to 80 second random start delay. After the random start delay and anti-short cycle delay,

the compressor relay will be energized. On all subsequent compressor calls, the random start delay is omitted.

Test Mode button:

Test mode allows the service technician to check the operation of the control in a timely manner. By momentarily pressing the TEST pushbutton, the DXM2 control enters a 20 minute test mode period in which all time delays are sped up 15 times.
