INSTALLATION
Please read all instructions carefully
before beginning installation.
TOOLS REQUIRED
#1 Phillips screwdriver (small)
Drill with 3/16-in. (4.8mm) bit
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 has been completed.
7. This thermostat does not require leveling.
C A U T I O N
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.
OFF
REMOVING THE OLD THERMOSTAT
Switch electricity to the furnace and air conditioner OFF;
then proceed with the following steps.
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.
MOUNTING THE TX1500 ON THE WALL
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.
C A U T I O N
Read instructions carefully
before removing any
wiring from 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.

• 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.
