installation
New Installations
The thermostat should be used indoors only. It should be mounted on
an inner wall in a location with freely circulating air, and where it will be
responsive to changes in room temperature. Avoid mounting near heat
generating appliances (i.e. TV, heater, refrigerator), or in direct sunlight.
Remove Old Thermostat
Turn off power to thermostat at main fuse or circuit breaker box.
Ensure that ALL power is disconnected.
to prevent electri-
cal shock and /or equipment damage, disconnect electrical
power to the system at the main fuse or circuit breaker until
installation is complete.
Remove the front cover of old thermostat. With wires still at
-
tached, remove wall plate from the wall. If the old thermostat has
a wall mounting plate, remove the thermostat and the wall mount-
ing plate as an assembly.
Before removing wires from old thermostat, label each wire
with the terminal designation from which it was attached.
Disconnect the wires from the old thermostat one at a time.
do
not let wires fall back into the wall.
