Cooling Only Thermostat
I have a 2003 Holiday Rambler Endeavor 38PST. In the hallway, there is a Honeywell T810C-1004 Cooling Only thermostat. When you adjust it you can hear a relay energize and de-energize in the front roof mounter Heat Pump. This seems to be independent of the Comfort Control Center. No matter how it is adjusted, it does not seem to affect either the heat pump units or their blowers, or the furnaces. Does anyone know the purpose of this thermostat?
