REMOVING OLD THERMOSTAT
To prevent electrical shock and/or equipment dam-
age, disconnectelectric power to system at main fuse
or circuit breaker box until installation is complete.
Before removing wires from old thermostat's switching sub-
base, label each wire with the terminal designation it was
removed from.
1. Shut off electricity at the main fuse box until installation is
complete. Ensure that electrical power is disconnected.
2. 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.
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.
5. Disconnect the wires from the old thermostat one at a
time. DO NOT LET WIRES FALL BACK INTO THE
WALL.
