INSTALLATION & OPERATION

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.

terminal Y, Red wire to terminal RH," etc.
Strip insulation 3 ⁄8" from wire ends and clean off any
■ ■
corrosion.
■ ■
Loosen all screws on the old thermostat and remove
it from the wall.

over wall opening. Decorative wall plate can
optionally be left off.

away each corner. Remove Base, Figure 2, from Sub-
Base, Figure 3, by loosening three captive screws.

Place Sub-Base, Figure 3, on wallplate over wall
opening. Mark wall with pencil at mounting holes as
shown in Figure 2. Now lay wallplate and Sub-Base to
the side.
■ ■
Drill two holes with 3/16" bit, 1" deep.
■ ■
Insert plastic screw anchors into drilled holes, flush
with wall surface.
■ ■
Bring wires through large hole in decorative wall plate
and through Hole For Wires in Sub-Base.
