proper connection.

UNINSTALLING THE EXISTING UNIT

1. Turn the system power OFF at 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.)

wall. (Some thermostats may have multiple covers, screws or other

locking devices that must be removed or disengaged.)

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.)

may want to secure the wires to the wall as you disconnect them. After

all wires are labeled, disconnect each wire and remove the existing

wall plate. (Any unused wires should be capped with an approved

electrical connector, such as electrical tape.)
