Make sure you follow all instructions for installing a new programmed thermostat before you install it. Two wires are usually required for this type thermostat. The base of the thermostat should have identical wiring. If there are more than two wires on the thermostat, it is likely that it is a direct-wired unit. You will need to follow the manufacturer’s instructions if you want to replace a thermostat which has more than 2 wires. Attach the faceplate of the new thermostat to the wall with the fasteners.
