On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, follow the guidelines listed below. 1. Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and in a room that is used often. 2. 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. 3. 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. 4. Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life. 5. Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open door. 6. Do not install the unit until all construction work and painting has been completed. 7. This thermostat does not require leveling. REMOVING THE OLD THERMOSTAT Switch electricity to the furnace and air conditioner OFF; then proceed with the following steps. Y W 1. 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. 2. 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. 3. Loosen all screws on the old thermostat and remove it from the wall. Read instructions carefully before removing any wiring from existing thermostat. Wires must be labeled before they are removed. When removing wires from their terminals, ignore the color of the wires since these may not comply with the standard. CAUTION MOUNTING THE TX1500 ON THE WALL Y W 1. Strip insulation 3/8 in. (9.5mm) from wire ends and clean off any corrosion. Y W R 2. Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat. 3. Press up on the button on bottom of thermostat and swing the body away from the base and up to remove the body from the base. Be careful not to drop the body or disturb electronic parts. Leave the cover closed while the body is being removed from the base. C A U T I O N © COPYRIGHT 2006 LUX PRODUCTS CORPORATION.
