4. 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). Attach the base to the
wall with the two screws provided.

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

1. Remove fresh batteries from their carton.
2. Remove body of thermostat as described at

bottom of first column.

3. Remove the used batteries.
4. Install two new Energizer

®

or DURACELL

®

'AA' size

alkaline batteries in the battery compartment.
Observe the polarity marking shown in the
compartment. Place body back on wall.

5. Hook the top of the body onto the base, swing the body down 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.

N O T E

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/ MAINTENANCE

The TX1500 requires batteries to operate your furnace and retain its

programming in memory and to light the display. Replace the batteries when the
REPLACE indicator appears in the display or at least once a year.
