Another Domestic Thermostat and AC Question
2014 Sunseeker 2860DS...
After reading the "replacing Domestic Thermostat thread" I was surprised its a 3 wire system. I have been wondering though on heating and cooling, is the system / fan supposed to keep running or shut of when not calling for heating or cooling. Mine runs constantly unless you shut off the thermostat.. Awful loud for light sleepers. I also didn't notice a slow speed fan!
Something wrong with my system?
