Every once n a while I run into an electronic thermostat I don’t understand. Several different HVAC contractors have told me that it’s fine to by-pass the controls at the furnace. Disconnect the white wire and hook an alligator-clip jumper between red and white lugs. They said you by-pass the circuit board this way and it’s perfectly safe.
I mentioned it at a NACHI meeting last spring, everyone seemed horrified and now I’m nervous about it. I don’t like to leave without testing the heating system.
Any thoughts on this?
