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/i6" bit, screwdriver, level and a pencil.
3) REMOVING OLD THERMOSTAT
Please read all instructions carefully. As you complete each step, check the
adjoining square [Z.
□ Disconnect electricity and turn off gas to the heater.
□ Remove cover from old thermostat.
□ Disconnect wires from thermostat, making sure they do not fall back inside the wall. Make
note of wires and to which terminals they are attached as you disconnect them. For
example: "Yellow wire to terminal Y, Red wire to terminal RH," etc.
□ Strip insulation 3/s" from wire ends and clean off any corrosion.
□ Loosen all screws on the old thermostat and remove it from the wall.
□ Fill wall opening with non-combustible insulation to prevent drafts from affecting thermostat.
4) INSTALLING NEW THERMOSTAT
□ Place new decorative wall plate (if supplied), Figure 4, over wall opening. Decorative
wall plate can optionally be left off.
□ Remove Front Cover of new thermostat by inserting a finger in the side of the
thermostat and gently prying 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. Mar1< 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/i6" 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.
□ Referring to your notes and the following diagrams, attach wires to terminal screws
shown in Figure 2. Make sure bare metal wires do not touch each other. Push all
excess wire back into wall.
