Newcsn Posted February 1 Share Posted February 1 I have all thermostats set at 70 & we appear to be getting heat out of all exchangers. However, on the control panel all zone lights & pump lights are lit except for the Zone#3 light. Any suggestions on how to troubleshoot this? Thanks!

If you are getting heat out of all 3 zones inside the coach, check the service bay to see if the fan on the aquahot heat exchanger is running. That heat exchanger is on a separate zone with its own thermostat in the service bay but shares the same circulating pump as the bath zone.
