1). THERMOSTAT LOCATION
For accurate temperature control and comfort, correct location is very
important. On new installations, the guidelines listed below should be
followed as closely as possible. When replacing an old thermostat,
install the new one in the same location unless these conditions
suggest otherwise.
1. Locate the thermostat on an inside wall about five feet above the floor,
where it is easy to install and adjust. It should be in a room that is used
often, such as a family room.
2. Do not install it where there are unusual heating conditions, such as
direct sunlight, close to a lamp, radio, television, radiator, register, near
a fireplace, or other heat producing appliance. Also, check for hot
water pipes within the wall, or a stove on the other side of the wall.
3. Do not locate in unusual cooling conditions, such as on an outside wall, or
one separating an unheated room, or in drafts from stairwells, doors, or
windows.
4. Do not locate in a damp or humid area. This can shorten thermostat life
due to corrosion.
5. Do not locate where air circulation is poor, such as in a corner, alcove,
or behind an open door.
6. Do not install until all construction work and painting have been
completed.
2) TOOLS REQUIRED
Wirestripper or knife, drill with 3⁄16" bit, screwdriver, level and a pencil.
3) REMOVING OLD THERMOSTAT

■■ Attach wires to terminal screws shown in Figure 2. (Either wire to
either terminal) Push excess wire back into wall opening.
■■ Find anticipator setting on old thermostat. Setting on new
thermostat should be the same. Do this by carefully sliding the
long pointer on the anticipator over the desired number. If old
anticipator setting cannot be determined, look on gas control on
furnace, or set it at .6. During heating season, furnace should
operate about five times an hour. If adjustments are necessary,
move heat anticipator pointer slightly and recheck. NOTE: Set
pointer to 1.2 for millivolt systems.
■■ Attach front cover, Figure 1, to base.
■■ Tur n electricity and gas back on and set pointer on top of
thermostat to desired temperature.
A thermostat can only control temperature near it. If
you find that it is uncomfortable some distance away
from the thermostat, change the setting in order to
compensate for this.
