SELECTING LOCATION
The proper location of the room thermostat is most
important to insure that it will provide a comfortable home
temperature. Observe the following general rules when
selecting a location:
‘1. Locate it about 5 ft. above the floor.
2. Install it on a partitioning wall, not on an outside wall.
3. Never expose it to direct light from lamps, sun, fireplaces,
etc.
4. Avoid locations close to doors that lead outside, windows,
or adjoining outside walls.
5. Avoid locations close to radiators, warm air registers, or in
the direct path of heat from them.
6. Make sure there are no pipes or duct work in that part of
the wall chosen for the thermostat location.
7. Never locate it in a room that is warmer or cooler than the
rest of the home, such as the kitchen.
8. The living or dining room is normally a good location,
provided there is no cooking range or refrigerator on
opposite side of wall.
ROUTING WIRES TO LOCATION
1. Before drilling hole in wall at selected location, take up
quarter round and drill a small guide hole for sighting.
From basement, drill 3/4” hole in partition floor next to
guide hole. (On basementless houses, drill 1/2” hole
through ceiling above partition.)
Probe for obstructions in the partition. Then drill 1/2” hole
through wall at selected location.
