•Do not install it where there are unusual heating conditions, such as: in direct sunlight; near a lamp, radio, television, radiator, register, or fireplace; near hot water pipes in a wall; near a stove on the other side of a wall.

•Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room; or in a draft from a stairwell, door, or window.

•Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.

•Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open door.

•Do not install the unit until all construction work and painting has been completed.

CAUTION:

•Read instructions carefully before removing any wiring from existing thermostat.

•Wires must be labeled before they are removed.

•Do not allow wires to touch each other or parts on thermostat.

•When removing wires from their terminals, ignore the color of the wires since they may not comply with any standard.

3.3. REMOVING THE OLD THERMOSTAT

1.Switch electricity to the furnace and air conditioner OFF; then proceed with the following steps.

2.Remove cover from old thermostat. Most are snap-on types and simply pull off. Some have locking screws on the side; these must be loosened.

3.Note the letters printed near the terminals. Attach labels (enclosed) to each wire for identification. Remove and label wires one at a time. Make sure the wires do not fall back inside the wall.

4.Loosen all screws on the old thermostat and remove it from the wall.

3.4. MOUNTING THE TX9000TS

5.Strip insulation leaving 3/8 in. (9.5mm) bare wire ends and clean off any corrosion.

6.Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat.

CAUTION:

Be careful not to drop the body or disturb electronic parts. Leave the cover closed while the body is being removed from the base.

7. Press up on the thumb latch at the bottom of thermostat and separate the body from its base.

8.Hold the base against the wall. Route the wires through the hole below the terminal block. Position the base for best appearance (to hide any marks from an old thermostat). Attach the base to the wall with the two screws provided.

NOTE:

If you are mounting the base to a soft material like plasterboard or if you are using the old mounting holes,

the screws may not hold. Drill a 3/16-in. (4.8mm) hole at each screw location, and insert the plastic anchors provided. Then mount the base as described below.

3.5. CONNECTING THE WIRES
