THERMOSTAT INSTALLATION
Thermostat is very sensitive. HANDLE WITH CARE AT ALL TIMES .
Locate thermostat 48˝ to 54˝ above floor on an INTERIOR wall.
Pick a dry area where air circulation is good. EXTERIOR wall
location must have a 3/4˝ spacer between thermostat and
exterior wall.
1. Be sure all electrical power has been disconnected from
the air conditioner, furnace and the power supply.
2. Do not install the thermostat where there are unusual
heating conditions: such as direct sunlight, heat produc-
ing appliances (television, radio, wall lamp, etc.)
or a furnace or air conditioner supply register.
3. ATTACHING THE WALL THERMOSTAT . Separate the thermostat
body from the sub-base by gently squeezing the top and
bottom. Pull wires through access hole in base plate.
Attach thermostat sub-base to the wall at the desired
mounting location. Mount the sub-base to the wall before
connecting the wires.
THIS THERMOSTAT HAS BEEN DESIGNED TO OPERATE STANDARD AIR CONDITIONING UNITS IN CONJUNCTION WITH AN EXCALIBUR 2 - STAGE FURNACE .
