What do you do with the ground wire when installing a new thermostat that doesn't have a connection for the ground wire It's a 4 wire Honeywell thermostat Is it ok to not connect the ground wire?
That Thermostat is LOW voltage. IT does not have a ground wire. There is no need for a ground. it only opperates on 24 volts. there may be a green wire but it does not mean it is a ground
