2 "AA" Batteries

Refer to equipment manufacturers' instructions for specific
system wiring information. After wiring, see CONFIGURA-
TION section for proper thermostat configuration.

For wiring diagrams, see 37-6740A.
Wiring diagrams shown are for typical systems and describe
the thermostat terminal functions.

2 "AA" alkaline batteries are included in the thermostat at
the factory with a battery tag to prevent power drainage.
Remove the battery tag to engage the batteries.
To replace batteries, set system to 

OFF, remove thermostat

from wall and install the batteries in the rear along the top of
the thermostat (see Figure 1).

A standard heat/cool thermostat consists of  three basic parts:
1. The cover, which may be either a snap-on or hinge type.
2. The base, which is removed by loosening all captive screws.
3. The switching subbase, which is removed by unscrewing

the mounting screws that hold it on the wall or adapter
plate. 

label each wire with the terminal designation from
which it was attached. Disconnect the wires from the old
thermostat one at a time. 

the wall.

1. Pull the thermostat body off  the thermostat base. Forcing

or prying on the thermostat will cause damage to the unit.

2. Place base over hole in wall and mark mounting hole

locations on wall using base as a template.

3. Move base out of  the way. Drill mounting holes. If  you

are using existing mounting holes and the holes drilled
are too large and do not allow you to tighten base snug-
ly, use plastic screw anchors to secure the base.

4. Fasten base snugly to wall using mounting holes shown

in Figure 1 and two mounting screws. Leveling is for
appearance only  and will not affect thermostat operation.

5. Connect wires to terminal block on base using

appropriate wiring schematic (see diagram sheet
37-6740A).

6. Push excess wire into wall and plug hole with a fire re-

sistant material (such as fiberglass insulation) to prevent
drafts from affecting thermostat operation.

7. Carefully line the thermostat up with the base and snap

into place.
