INSTALLATION

SELECT THERMOSTAT LOCATION

Proper location insures that the thermostat will provide a comfortable home temperature. Observe the follow- ing 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.

INSTALL THERMOSTAT

Install the thermostat as follows:

1.Before mounting, connect system wiring to proper color-coded leads at rear of thermostat. Follow equipment manufacturer's instructions or refer to wiring diagram for typical system hookups.

2.Remove thermostat cover by grasping top and bottom of cover and pull straight out. Dress wiring into junction box and secure thermostat to outlet box with mounting screws.

NOTE

DO NOT PUSH OR DAMAGE THE TEMPERATURE KNOB DURING INSTALLATION.

3.Install thermostat cover, turn knob to desired set- ting, and set selector switches for the appropriate system function and fan speed.

!CAUTION

To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until instal- lation is complete.

The thermostat may be mounted on a standard 2 x 4 inch vertical outlet box or 2-ganged outlet boxes. When mounting to a 4 x 4 inch junction box is required, use of a standard adapter plate (not provided) is necessary.
