Help! I have a roof mounted heat pump system. It had a pretty much broken honeywell mechanical thermostat installed but had the following symptoms:
In order to get the compressor to kick on an cool, I had to crank the thermostat down to the min and tap the mercury switch thingy at the end of thermo spring to make sure it made good contact. The compressor then comes on fine.
The air handler however won't turn off without cutting off the breaker. I suspect the person who wired the thermostat didn't have any idea what he was doing judging from some of the other wiring in the house.
My handyman tried to wire up a new digital thermostat first by matching up colors (nothing worked) then by trying to determine what each wire was for and hood them to the correct spot on the thermostat. We are now in same the situation as with the mechanical. Airhandler runs continuously, and the compress will not come on since I can't manually ensure the connection is made as I could with the mechanical one.
I have read some stuff here that say if the air handler is running all the time it might be a relay, or control board. Does wiring problems seem more likely in this case? Is there a way to wire the thing to produce the symptoms I am seeing?
Any help would be GREAT!
Thanks!
