WHEN INSTALLING THIS PRODUCT...
1. Read these instructions carefully. Failure to follow
them could cause a hazardous condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained experienced service tech­
nician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
/ \
1. Disconnect power supply to prevent electrical
shock or equipment damage.
2. To prevent interference with the thermostat link­
age, keep wire length to a minimum and run
wires as close as possible to the subbase.
3. Push excess wire back into the hole and plug
hole to prevent drafts from affecting thermostat
operation.
4. Do not overtighten thermostat captive mount­
ing screws because damage to subbase threads
can result.
5. Do not short across coil terminals on relay. This
can burn out the thermostat heat anticipator.
6. Never install more than one wire per terminal
unless factory-supplied jumper with spade ter­
minals is used.
IMPORTANT: Thermostats are claibrated at the factory
mounted at true level. Inaccurate thermostat leveling
will cause the actual temperature to deviate from the
setpoint temperature.
Locate New Thermostat
Locate thermostat about 5 ft (1.5m) above the floor in an
area with good air circulation at average temperature. Do
not mount the thermostat where it may be affected by—
— drafts, or dead spots behind doors and in corners.
— hot or cold air from ducts.
— radiant heat from the sun or appliances.

behind the thermostat.
The number of wires required to connect this thermostat
to the heating, cooling, or heating/cooling equipment de­
pends on how the thermostat is powered—by the 24 Vac or
battery, or through the control system. Refer to the Typical
Wiring Diagrams section to determine the number of wires
required for your application.
Unpack Thermostat

Mount Wallplate or Subbase
WALL MOUNTING (FIG. 2)
Hold the wallplate or subbase in position on the wall
(Fig. 2).
Mark holes on the wall for anchors. Use spirit level to
make sure the wallplate or subbase is level.
Drill 3/16 in. holes, and gently tap anchors into holes
until flush with the wall.
Pull wires through the large wiring hole in the wallplate
or subbase.
Loosely fasten the wallplate or subbase to the wall with
the three screws. Do not completely tighten the screws.
Carefully level the wallplate or subbase (Fig. 3), and
firmly tighten the screws.
