Once that is verified, the owners manual should be informative enough to complete the change over very easy. You could also see if your stat allows for a power stealing resistor to be installed unlikely normally only on hydronic radiant heating stats.

This type thermostat is relatively easy to connect or change over to a programmable type thermostat. These new circuits require a path for electricity to return to the source, and so require an extra wire. Check the thermostat manual or air conditioner diagram for color coded. How to Wire Air Conditioning Thermostats How to wire a thermostat To wire air conditioning thermostats, you need to know what types of thermostat your air conditioner needs.

This is for the Heat Pump reversing valve to energize the unit in heating mode. This terminal will call for the need to cool the room when the set temperature is lower than the room temperature. Circuit boards or printed circuit boards found in modern systems utilize volt control which originates from the control transformer. EarlCook jumping the neutral with the hot is just going to result in a short. Green wire is the wire that comes from relay and it controls the fan.

These are the typical physical characteristics of a transformer. You'd need an unused wire, or one that you don't mind always being on e. Furthermore, you can lower energy bills and energy cost by installing a smart thermostat or a programmable thermostat.
