• 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.

TOOLS REQUIRED

#1 Phillips screwdriver (small)

Drill with 3/16-in. (4.8mm) bit

Wire stripper/cutter

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.

• Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, in a room that is used often.
• 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.
• 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.
• Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.
• Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open door.
• Do not install the unit until all construction work and painting has been completed.

CAUTION:

• Read instructions carefully before removing any wiring from existing thermostat.
• Wires must be labeled before they are removed.
• Do not allow wires to touch each other or parts on thermostat.
• When removing wires from their terminals, ignore the color of the wires since they may not comply with any standard.

REMOVING THE OLD THERMOSTAT

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

2. 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.

3. 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.

4. Loosen all screws on the old thermostat and remove it from the wall.

MOUNTING THE TX9000TS

5. Strip insulation leaving 3/8 in. (9.5mm) bare wire ends and clean off any corrosion.

6. Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat.

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.

7. Press up on the thumb latch at the bottom of thermostat and separate the body from its base.

8. Hold the base against the wall. Route the wires through the hole below the terminal block. Position the base for best appearance (to hide any marks from an old thermostat). Attach the base to the wall with the two screws provided.

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.

CONNECTING THE WIRES

9. Loosen wire clamp screws just enough to slide wire under the black top part of the clamp.

10. Using your label, and diagrams below determine appropriate wiring for you system.

11. If you are unsure or need assistance, call the LUX Technical Assistance Dept. (see technical assistance.)

12. Slide proper wire between the brass back and black top clamp.

COMPLETING YOUR INSTALLATION

14. Install two(2) Energizer or DURACELL "AA" size alkaline batteries at this time. For instructions, see "BATTERIES & MAINTENANCE".

15. Initially, your thermostat will display "SUN 12:00 AM". To correct the display, refer to "Setting the DAY and TIME" in the "OPERATING INSTRUCTIONS" section of this manual.

16. Install your TX9000TS on its base. To do this hang the top of the unit by the tabs on the base, then snap the bottom of the unit into place. Do not use unnecessary force. If the body does not snap into place easily, remove the body, re-hang it from the tabs and try again.

17. Turn the power back on to your heating and/or air conditioning system.

18. Verify that the system and its fan are operating properly. When set to a high temperature, the heating system should provide warm air after a short time. Likewise a cooling system should provide cool air after a short time. Usually sound from the furnace and air conditioning units can be heard while they are running. The rush of moving air should be heard within a short time after either has been started.

NOTE: If you have an electric heat system and the blower does not operate after installation, see figure in SETUP OPTIONS Section to find the electric/gas heat jumper on the back of the body. Move the jumper to the ELEC position.

19. Your installation is now complete.

SETUP OPTIONS

There are Installation Option switches located inside the thermostat on the rear of its circuit board. They control the following:

TIME DISPLAY FORMAT 12/24 SWITCH #1

The position of this switch controls whether the time is displayed in 12 hour or 24 hour Military Time format.

SMART RECOVERY SWITCH #2

Smart Recovery allows your HVAC system to attempt to recover from a setback period and reach your desired comfort temperature set point by the beginning of your programmed comfort period. This option allows you to choose whether to use Smart Recovery.

When enabled, Smart Recovery will initiate if:

• Recovery is from an evening setback to morning comfort or day setback to evening comfort period.
• In Heat mode the temperature set point of the comfort period must be higher than the setback period.
• In Cool mode the temperature set point of the comfort period must be lower than the setback period.
• The estimated Smart Recovery time must be longer than 15 minutes for a Smart recovery to be initiated.
• Maximum Smart Recovery time is one hour.
• The Smart Recovery temperature set point must be achievable. If a desired smart recovery is repeatedly ignored by your thermostat. That is an indicator that you should modify your program so that the recovery can be achieved within the 1 hour limit.
• A Smart Recovery may not be initiated for 48 hours after the units programs have been changed. This allows the unit to gather the data necessary to predict a Smart Recovery time.

TEMPERATURE DISPLAY FORMAT ˚F/˚C SWITCH #3

The position of this switch controls whether the temperature is displayed in degrees ˚F or ˚C.

5 MIN / 2 MIN MINIMUM RUN TIME SWITCH #4

The position of this switch controls minimum length of time the thermostat must remain with Heat or Cool either ON or OFF before it will automatically switch to the alternate ON or OFF state. This feature prevents short cycling and provides compressor protection for cooling units. Choices are 2 or 5 minutes.

REPOSITIONING SWITCHES

Use this table to determine the positions which correspond to the operation you prefer.

This table is printed on the circuit board. To change a switch position move switch down or up. After settings have been changed with batteries installed, press the Hardware Reset (H.W. Reset) button on the rear of the unit's circuit board for changes to take effect.

GAS/ELECTRIC JUMPER

In HEAT mode, the position of this jumper controls when the thermostat requests the system fan to run. In Gas mode the fan is normally controlled by the heating system itself. In Electric mode, the fan is controlled by the thermostat.
