Heat Pump Thermostat Troubleshooting!

This HVAC Video is about troubleshooting Heat Pump thermostats. I go over what wire does what, which wires to test, how to test them. I go over wire colors, terminal functions, aux, and emergency heat as well as when the reversing valve is supposed to be powered as well as other tips. I show how you can be sure that the problem is within or not within the thermostat.
