FEATURES
•The unit can be used with most
24 volt gas, oil or electric heating and
air conditioning systems, gas millivolt heating systems, and single stage heat pumps.
It cannot be used with 120 volt heating systems or two stage heat pumps. Ask your dealer for
other LUX thermostats to control those systems.
•A large easy to read display shows you the current room temperature at all times.
•The unit has a built in digital control system
to accurately control the temperature in your home.
•The unit will learn the temperature characteristics of your home on a daily basis and customize the control to give you the best comfort possible from a digital thermostat.
•You can also select a tighter temperature control if you have a forced hot water system or if closer comfort is preferred over energy savings.
•A press of either the Temperature Up or Down key will reveal the current Set Temperature.
•A 4-minute minimum off time in COOL prevents your air conditioning system from being damaged.
•Two Energizer® or DURACELL® “AA” alkaline batteries (not included) are used to retain your time and temperature programs.
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.

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.
