When there is no communication in the ClimateMaster Tranquility 30 system, follow these troubleshooting steps:

1. Check Thermostat: Ensure a communicating thermostat is installed. If not, use a communicating service tool for configuration and diagnosis.

2. Verify Connections: Confirm proper wiring between the thermostat and DXM2 control board. Check terminals R, C, and communication wires.

3. Inspect Power Supply: Make sure 24Vac Hot (R) and 24Vac Common (C) are present and supplying correct voltage.

4. Use Diagnostic Tool: If communication is still absent, connect a diagnostic tool to the system for two-way communication and troubleshooting.

5. Check DIP Switch Settings: Verify DXM2 board DIP switch S2-7 is set correctly if dehumidification is used.

6. Review Fault LEDs: Check for any fault indication on LED L or AL1 to help identify communication or system issues.

Page 23: Water Quality Standards
Rev.: 3/22/2012 The ClimateMaster Water Quality Table provides water quality requirements for ClimateMaster coaxial heat exchangers. When water properties are outside of those requirements, an external secondary heat exchanger must be used to isolate the heat pump heat exchanger from the unsuitable water. Failure to do so will void the warranty for the coaxial heat exchanger.
