INSTALLATION & OPERATION

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.

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.
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.
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.
Do not locate in a damp or humid area. This can shorten thermostat life due to corrosion.
Do not locate where air circulation is poor, such as in a corner, alcove, or behind an open door.
Do not install until all construction work and painting have been completed.

TOOLS REQUIRED

Wire stripper or knife, drill with ³⁄₁₆" bit, screwdriver, level and a pencil.

REMOVING OLD THERMOSTAT

Please read all instructions carefully. As you complete each step, check the adjoining square ✓.

Disconnect electricity and turn off gas to the heater.
Remove cover from old thermostat.
Loosen all screws.
Disconnect wires from thermostat, making sure they do not fall back inside the wall.
Strip insulation ³⁄₈" from wire ends and clean off any corrosion.
Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat.

INSTALLING NEW THERMOSTAT

Place new decorative wall plate (if supplied), Figure 3, over wall opening. Decorative wall plate can optionally be left off.

FIGURE 2 BASE
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 Base.
Fasten Base loosely to wall using two mounting screws. Place a level against the bottom of the Base, adjust until it is level and then tighten mounting screws to secure the Base.
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.
Turn 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.
