uninstalling the existing unit
1.Turn the system power OFF from the existing thermostat. Turn the power to the HVAC system OFF at the main power panel or at the furnace.
(Failure to turn off the power to the existing thermostat before removal could damage your system.)
2.Remove the existing thermostat cover to access the wires from the wall.
(Some thermostats may have multiple covers, screws or other locking devices that must be removed or disengaged. See page 8 for common examples.)
3.Locate, but do not disconnect the wires.
(If wires are not visible, they may be connected to the back of the wall plate. Some models may have doors that open to expose the wires and mounting screws.)
