5. Install new thermostat using the following procedures.

ATTENTION!

This product does not contain mercury. However, this product
may replace a unit which contains mercury.

Do not open mercury cells. If a cell becomes damaged, do not
touch any spilled mercury. Wearing nonabsorbent gloves, take
up the spilled mercury with sand or other absorbent material and
place into a container which can be sealed. If a cell becomes
damaged, the unit should be discarded.

Mercury must not be discarded in household trash. When the
unit this product is replacing is to be discarded, place in a
suitable container and return to White-Rodgers at 2895 Harrison
Street, Batesville, AR 72501 for proper disposal.

ELECTRIC HEAT OR SINGLE-STAGE

HEAT PUMP SYSTEMS

This thermostat is configured from the factory to operate a heat/
cool, fossil fuel (gas, oil, etc.), forced air system. It is configured
correctly for any system that DOES NOT require the thermostat
to energize the fan on a call for heat. If your system is an electric
heat or heat-pump system that REQUIRES the thermostat to
turn on the fan on a call for heat, locate the GAS/ELECTRIC

GAS/ELECTRIC

switch

switch on the back of the thermostat (see fig. 1) and switch it to
the ELECTRIC

ELECTRIC

ELECTRIC position. This will allow the thermostat to ener-

gize the fan immediately on a call for heat. If you are unsure if
the heating/cooling system requires the thermostat to control
the fan, contact a qualified heating and air conditioning service
person.

ATTACH THERMOSTAT BASE TO WALL

1. Remove the packing material from the thermostat. Gently

pull the cover straight off the base. Forcing or prying on the
thermostat will cause damage to the unit. If necessary, move
the electric heat switch (see ELECTRIC HEAT SYSTEMS

ELECTRIC HEAT SYSTEMS

ELECTRIC HEAT SYSTEMS,

above).

2. Connect wires beneath terminal screws on base using

appropriate wiring schematic (see figs. 2 through 7).

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

locations on wall using base as a template.

4. Move base out of the way. Drill mounting holes.

5. Fasten base loosely to wall, as shown in fig. 1, using two

mounting screws. Place a level against bottom of base,
adjust until level, and then tighten screws. (Leveling is for
appearance only and will not affect thermostat operation.) If
you are using existing mounting holes, or if holes drilled are
too large and do not allow you to tighten base snugly, use
plastic screw anchors to secure subbase.

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

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

BATTERY LOCATION

2 "AA" alkaline batteries are included in the thermostat at the
factory with a battery tag to prevent power drainage. You must

replace batteries, install the batteries along the top of the base
(see Fig. 1). The batteries must be installed with the positive (+)
end to the left.

HYDRONIC (HOT WATER OR STEAM)

HEATING SYSTEMS

This thermostat is set to operate properly with a forced-air
heating system. If you have a hydronic heating system (a
system that heats with hot water or steam), you must set the
thermostat to operate properly with your system. Change the
second option in the configuration menu to SL (see CONFIGU-
RATION MENU, page 4).

CHECK THERMOSTAT OPERATION

If at any time during testing your system does not operate
properly, contact a qualified service person.

Turn on power to the system.
