ClimateMaster’s Communicating Service Tool (ACDU03) allows install and service technicians to confi gure and diagnose
ClimateMaster Digital Communicating Units without installing a digital communicating thermostat.
Using the Service Tool, a technician can ELECTRONICALLY:
1. Confi gure items like: airfl ow, heat pump options and confi guration, pump or modulating valve operation, unit family, unit
size, etc.
AND
2. Diagnose the unit by operating it manually, performing control diagnostics, viewing dip switch confi gurations, or by
viewing fault history and operating conditions when a fault occurred.
The Service Tool connects to the DXM2 board with a 4-Wire Connector as shown below:
Note: For Vertical Stack models (TSM, TSL) must
order harness for connection to service port outside
chassis. Harness part number 11B0100N27. DXM2 to
service port is factory wired.
