PREPARATIONS

To prevent electrical shock and/or equipment damage,

disconnect electrical power to the system at the main fuse

or circuit breaker until installation is complete.

CAUTION

Before removing wires from old thermostat’s switching subbase,

label each wire with the terminal designation it was removed

from.

1. Remove Old Thermostat: A standard heat/cool thermostat

consists of three basic parts:

a. The cover, which may be either a snap-on or hinge type.

b. The base, which is removed by loosening all captive screws.

c. The switching subbase, which is removed by unscrewing

the mounting screws that hold it on the wall or adaptor plate.

2. Shut off electricity at the main fuse box until installation is

complete. Ensure that electrical power is disconnected.

3. Remove the front cover of the old thermostat. With wires still

attached, remove wall plate from the wall. If the old thermostat

has a wall mounting plate, remove the thermostat and the wall

mounting plate as an assembly.

4. Identify each wire attached to the old thermostat using the

labels enclosed with the new thermostat.

5. Disconnect the wires from the old thermostat one at a time. DO

NOT LET WIRES FALL BACK INTO THE WALL.

6. Install new thermostat using the following procedures.
