WIRING CONNECTIONS

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

For wiring diagrams, see next page.
Wiring diagrams shown are for typical systems and describe
the thermostat terminal functions.

INSTALLATION

Battery Location

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

OFF

OFF, remove thermostat

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

Remove Old Thermostat

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. Bef

Installing New Thermostat

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 diagrams on next
page).

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.
