INSTALLATION AND OPERATING

INSTRUCTIONS

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.

52021

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.

■ 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.

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.
