9. Insert the two longer mounting screws provided through the right and left Trim Plate screw holes  
and thread each screw into the mounting holes into the wall or the plastic screw anchors.  
10. Carefully push all excess wire back into the wall. Align the thermostat sub-base with the  
decorative wall plate by using the 3 alignment pins and holes molded into the back of the  
subbase and Trim Plate. Attach the Sub-Base to the Trim Plate using the two smaller mounting  
screws provided. Thread these two small screws into the single inner holes in the Trim Plate.  
11. Now that the Sub-Base is mounted, align the front portion of the thermostat with the Sub-Base  
using the Light Button and the cutout for it in the Sub-Base. While holding the thermostat in  
place against the Sub-Base, carefully and evenly tighten the 3 silver captive screws that are held  
in place inside the front of the thermostat assembly.  
IMPORTANT!  
Please read all instructions carefully before beginning installation and save for future  
reference. Before removing any wiring from your existing thermostat, the wires must  
be labeled with their terminal designations. Ignore the color of the wires since they  
may not comply with any standard.  
Thank you for your confidence in our product. To obtain the best results from your investment,  
please read these instructions thoroughly. You should become fully acquainted with this thermostat  
before installing it for usage. Follow the installation procedures carefully, and one step at a time.  
This will save you time and minimize the chance of damaging either the thermostat or the systems  
that it controls. These instructions may contain information beyond that required for your particular  
installation. Please save these instructions for future reference.  
WIRING INFORMATION  
** Complete heating and/or cooling system wiring can be found in the WIRE IDENTIFICATION AND  
WIRING SCHEMATICS section of this instruction sheet. The schematics shown provide component  
information for brand new installations or for unreferenced wires.  
COMPATIBILITY  
This mechanical thermostat can be used with most single-stage 24 volt gas or oil heating and air  
conditioning systems. It cannot be used with heat pumps, 3 wire zone valves, line voltage (120/240  
volt) heating systems, or Millivolt systems. Ask your dealer for other LUXPRO thermostats to  
control those systems.  
SETUP  
The only item that will need to be tailored to your  
system is the Heat Anticipator. This setting is for  
heating systems only. If you are using this  
thermostat on a “cooling only” system with no  
heater, the Anticipator does not need to be set and  
can be left as is.

FEATURES  
Anticipator  
Adjustment  
• Push Button Back Light  
• Glow-In-The-Dark Dial Numbers  
• Soft Rubber Set Temperature Ring  
• Large Easy To Use Mode Switches  
If you are replacing an old mechanical thermostat,  
find the Anticipator setting on the old thermostat,  
Fan  
Mode  
Light Button  
and set the new thermostat to the same value. Do this by carefully sliding the silver metal pointer,  
shown here, over desired number printed on the Anticipator scale. If an old Anticipator setting  
cannot be determined, look on the gas control valve on your furnace, and find either the Anticipator  
Value or a Current Rating. This will be the value to use for the Anticipator setting. If you cannot find  
either of these numbers, set it to .6 initially to start with. During heating season, your furnace  
should operate about five times an hour. If adjustments are necessary, move heat anticipator pointer  
slightly and recheck. A lesser value will cause your heater to cycle more frequently, and a larger  
value will cause it to cycle less frequently.

OPERATION  
There are two mode switches on the front, a Temperature mode switch and a Fan mode switch. The  
Temperature mode switch has three positions: HEAT, OFF, and COOL. 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 the spring and fall or when the windows are open, you can set the switch  
OFF. The Fan mode switch has two positions, AUTO and ON. Setting the Fan mode switch to AUTO,  
automatically runs your system's blower fan as required only during heating and cooling activation.  
Setting the Fan mode switch to ON, runs your system’s fan continuously, even if heating or cooling is  
not needed, including when the Temperature mode switch is in the OFF position to provide air  
circulation only. In either HEAT or COOL mode, turn the front thermostat dial to the desired  
temperature setting.

SELECTING A 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 locate where air circulation is poor, such as in a corner or an alcove, or behind an open  
door.  
3. Do not install it where there are unusual heating conditions, such as: in direct sunlight; near a  
lamp, television, radiator, register, or fireplace; near hot water pipes in a wall; near a stove on the  
other side of a wall.  
4. 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.  
BACKLIGHT  
This thermostat has an illuminated panel to assist in reading the temperature while in low light  
conditions. While in HEAT or COOL mode, press and hold the button on the top of the thermostat.  
The backlight will not operate while the thermostat is in OFF mode.  
5. Do not locate in a damp area. This can lead to corrosion that may shorten thermostat life.  
6. If painting or construction work has yet to be completed, cover the unit completely or do not  
install it.
