Thermostat Overview


Before you begin installing your thermostat, please be advised that It is always a good practice to consult the owner’s manual for your HVAC system.  If necessary, consult an HVAC technician to ensure proper installation.

Thermostat installation begins with determining the type of unit you are controlling.  Start by following these steps below.

1.Remove the existing thermostat to expose the connected wiring
2.Take a photo or write down the way the wires are wired to the existing thermostat

Here you see sample images of two of the most common HVAC systems and their wiring.
