LUX TX500 Series Manuals

LUX PRODUCTS CORPORATION • Mt. Laurel, New Jersey 08054, USA • In cool weather, when the system switch is set to HEAT, the TX500 will maintain cooler “set back” room temperatures to save energy. It will then change to warmer “comfort” settings - all automatically, at specified times during the day. • In warm weather, when the system switch is set to COOL, the TX500 will maintain warmer “set back” room temperatures to save energy. It will then change to cooler “comfort” settings - all automatically, at specified times during the day. • A large liquid crystal display shows time, day of the week, and room and set temperatures. • A 4-minute minimum off time in COOL prevents your air conditioning system from being damaged. • Two “AA” batteries (not included) are used to retain your time and temperature programs. Thank you for your confidence in our product. To obtain the best results from your investment, please read this manual and acquaint yourself with your purchase before installing your new thermostat. Then follow the installation procedures, one step at a time. This will save you time and minimize the chance of dam- aging the thermostat and the systems it controls. These instructions may contain information beyond that required for your particular installation. Please save for future reference. I M P O R T A N T ! READ THE INSTALLATION INSTRUCTIONS FIRST. FEATURES • The TX500 can be used with most 24 volt gas, oil or electric heating and air conditioning systems or gas millivolt heating systems. It cannot be used with 120 volt heating systems or heat pumps. Ask your dealer for other LUX thermostats to control those systems. • The TX500 is programmable. There are four programming periods per day. Each period can be programmed separately. • You can use the built-in time/ temperature programs, or alter them to suit your schedule. The TX500 provides separate programming for weekdays and weekends — for both heating and cooling. You can override the programmed temperatures for as little as one program- ming period or for an entire vacation.

TOOLS REQUIRED #1 Phillips screwdriver (small) Drill with 3⁄16-in. (4.8mm) bit THERMOSTAT LOCATION 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. 2. Note the letters printed near the terminals. Attach labels (enclosed) to each wire for identifi- cation. 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. MOUNTING THETX500 ON THE WALL 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. C A U T I O N Read instructions carefully before removing any wiring from existing thermostat. Wires must be labeled before they are removed. When removing wires from their ter- minals, ignore the color of the wires since these may not comply with the standard. C A U T I O N Be careful not to drop the body or disturb electronic parts. Leave the cover closed while the body is being removed from the base. 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 loos- ened. Y W R 2. Fill wall opening with non-combustible insula- tion to prevent drafts from affecting the ther- mostat. Y W 1. Strip insulation 3⁄8 in. (9.5mm) from wire ends and clean off any corrosion. INSTALLATION C A U T I O N To avoid electrical shock and to prevent damage to the furnace, air conditioner, and thermostat, disconnect the power supply before beginning work. This can be done at the fuse box, at the circuit breaker, or at the appliance. OFF
