IMPORTANT!

READ INSTALLATION INSTRUCTIONS FIRST

Thank you for your confidence in our product. To obtain the best results from your investment, please read these instructions 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 damaging the thermostat and the systems it controls. These instructions may contain information beyond that required for your particular installation. Please save for future reference.

FEATURES

• The Unit can be used with most 24-volt gas, oil or electric heating and air conditioning systems, single-stage heat pumps, or gas millivolt heating systems. It cannot be used with 120 volt heating systems or multistage heat pumps. Ask your dealer for other LUX thermostats to control those systems.
• The Unit 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 Unit provides separate programming for every day
  of the week- 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 Unit 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 Unit 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.
  It will remind you when the filter should be changed in your blower and track your system’s energy usage.
• Temperature swing adjustment lets you fine-tune your system for maximum comfort and economy.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.

CAUTION

• Your thermostat is a precision instrument. Please handle it with care.
• Turn off the electricity to the appliance before installing or servicing the thermostat or any part of the system. Do not turn the electricity back on until work is completed.
• Do not short (jump) across electric terminals at the control on the 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

CAUTION 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.

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 have been completed.
7. This thermostat does not require leveling.

REMOVING THE OLD THERMOSTAT

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

1. Remove the cover from the 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.

CAUTION
Read instructions carefully before removing any wiring from the 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.

MOUNTING THE UNIT ON THE WALL

1. Strip insulation 3/8 in. (9.5mm) from wire ends and clean off any corrosion.
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.
   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.
   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.

Attaching Wires

Hold the base against the wall, with the wires coming through wherever it is convenient for wiring. Route the wires to below the terminal block. Position the base for best appearance (to hide any marks from an old thermostat). An optional wall plate is included for covering old mounting holes. Attach the base to the wall with the two screws provided.

CAUTION: Do not allow wires to touch each other or parts on the thermostat. Wires must be trapped between the black spacer and brass terminal. Also, be sure to tighten securely all 7 electrical terminal screws.

WIRING DIAGRAMS

WIRING DIAGRAM NOTES
(APPLIES TO ALL DRAWINGS)

• The DASHED lines are optional depending on your system type.
• Verify whether “C”, “X” or “B” wires are connected to the system common.
• If “B” and “O” are both presents, it is likely that “B” is a system common.
• If a “B” wire in your system is common, then connecting it to the “B” terminal may cause damage to your system.
• If “Y” and “C” are both present, it is likely that “C” is a system common.

These diagrams below are provided for new installations or unreferenced wires.

NOTE
If you have an electric system and the blower does not operate after installation, find the electric/gas heat selector on the back of the body. Move the selector to the ELEC position.

INSTALLING BATTERIES

The Unit requires batteries to operate your furnace and retain its programming in memory. Replace the batteries when the REPLACE indicator appears in the display or at least once a year.

WARNING: Use Energizer® or DURACELL® Alkaline Batteries Only.
NOTE: When replacing batteries, you have approximately 1 minute before programs are lost.

1. Remove fresh batteries from their carton.
2. Remove the body of the thermostat as described at bottom of the first column.
3. Remove the battery clip and batteries.
4. Install two new Energizer® or DURACELL® “AA” size alkaline batteries in the battery compartment. Observe the polarity marking shown in the clip.
5. Place the body back on the wall. Hook the bottom of the body onto the base, swing the body up, and snap the body onto the base.

Installation is now complete. Be sure to turn the power back on to your heating and /or air conditioning system. If this is the first time you are installing batteries, the thermostat will display “SUN 12:00 AM”. Within 90 seconds the thermostat will begin to display the room temperature alternately with the time. To correct the display, see “Setting the TIME and DAY,” after you set the programs.

CAUTION
The Unit is protected against normal static electric discharges. However, in extremely dry weather you should touch another metal object before the Unit to avoid potential loss of programs.

OPERATION

This thermostat is “armchair programmable” You can make any program or setting changes with the thermostat body off or on the wall thermostat base.

• The Unit alternately displays the current time and the room temperature. It also displays the day of the week and the currently active program period that is controlling the temperature: MORN, DAY, EVE, or NIght.
• The set point temperature will appear in the right side of the display. In the winter, set the system switch to HEAT to control your heating system. In the summer, set the switch to COOL to control your air conditioner. In spring and fall or when windows are open, you can set the system switch OFF.
• Setting the FAN switch to AUTO automatically runs your system’s fan during heating and cooling. Setting the FAN switch to ON runs your system’s fan continuously even without heating or cooling.

SMART RECOVERY

Your thermostat has the capability to turn the HEAT and AIR CONDITIONING ON in your home so that it reaches your desired comfort temperature at the time you have programmed. For instance, if you have programmed your thermostat for 70° at 5:00 pm, normally the thermostat will begin to heat your home at 5:00 pm. With SMART RECOVERY on, the thermostat will calculate the best time to turn the heat on so that the temperature in your home reaches 70° by 5:00 pm. It calculates the amount of time through experience and will get more accurate as time goes by. To enable SMART RECOVERY, remove J4 on the back of the thermostat. Press the small reset button on the front of the thermostat. IN RECOVERY will appear in the display when this feature is bringing your home to temperature.
