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 programming period or for an entire vacation.

•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.
•5/2 Minute Selectable Minimum Run/Off Time for Short Cycle/Compressor Protection.
•Two Energizer® or DURACELL® “AA” alkaline batteries (not included) are used to retain your time and temperature programs.
WARNING: Use Energizer® or DURACELL® Alkaline Batteries Only.
C A U T I O N
•Your thermostat is a precision instrument. Please handle it with care.
•Turn off electricity to the appliance before installing or servicing thermostat or any part of the system. Do not turn electricity back on until work is completed.
•Do not short (jumper) across electric terminals at control on furnace or air conditioner to test the system. This will damage the thermostat and void your warranty.
•All wiring must conform to local codes and ordinances.
•This thermostat is designed for use with 24 volt and millivolt systems. The thermostat should be limited to a maximum of 1.0 amps; higher amperage may cause damage to the thermostat. If you are in doubt, call your utility company.
INSTALLATION
Please read all instructions carefully before beginning installation.
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.
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.
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 |
1. Remove cover from old thermostat. |
W |
Most are snap-on types and simply pull off. Some have locking screws on the side. These must be loosened.
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 terminals, ignore the color of the wires since these may not comply with the standard.
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.

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.
