INSTALLATION
SELECT THERMOSTAT LOCATION
Proper location insures that the thermostat will provide a
comfortable home temperature. Observe the following
general rules when selecting a location.
1. Locate thermostat about 5 ft. above the floor.
2. Install thermostat on a partitioning wall, not on an
outside wall.
3. Never expose thermostat to direct light from lamps,
sun, fireplaces or any temperature radiating equip-
ment.
4. Avoid locations close to windows, adjoining outside
walls, or doors that lead outside.
5. Avoid locations close to air registers or in the direct path
of air 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 thermostat in a room that is warmer or
cooler than the rest of the home, such as the kitchen.
8. Avoid locations with poor air circulation, such as behind
doors or in alcoves.
9. The living or dining room is normally a good location,
provided there is no cooking range or refrigerator on
opposite side of wall.
ROUTE WIRES TO LOCATION
NOTE
All wiring must conform with local and national electrical
codes and ordinances.
1. If an old thermostat is being replaced and is in a
satisfactory location, and the wiring appears to be in
good condition, use existing wiring. If in doubt, rewire.
2. If a new location is chosen or if this is a new installation,
thermostat wiring must first be run to the location
selected.
APPLICATIONS:
The 1E56(W) / 1F56(W) is designed for use with
• Standard heating and cooling systems
• Two-transformer systems
This thermostat CAN NOT BE USED with
• Millivolt systems (self-generating systems that do
not have a transformer or relay)
• Three-wire zone valve systems
• Multi-stage applications
• Heat-pump systems
• Electric heat furnace where thermostat must
energize fan.
3. Probe for obstructions in partition before drilling
in wall at selected location. Take up quarter round and
drill a small guide hole for sighting (see Fig. 1). From
basement, drill

hole. In basementless houses, drill
ceiling and into partition from above (see Fig. 1).
4. Through this hole drop a light chain, or 6" chain
attached to a strong cord. Snag cord in basement with
hooked wire. In basementless houses, drop cord
through hole in ceiling and down partitioning; snag
cord at the thermostat location.
5. Attach thermostat wires to cord and pull thermostat
wires through hole in wall so that 6" of wire protrudes.
!
To prevent electrical shock and/or equipment
damage, disconnect electric power to system at
main fuse or circuit breaker box until installation
is complete.
