INSTALLATION AND OPERATION INSTRUCTIONS

Operator: Save these instructions for future use!

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

Your new White-Rodgers Digital Thermostat uses the technol­ogy of a solid-state microcomputer to provide precise time/
temperature control. This thermostat offers you the flexibility to
design heating and cooling programs that fit your needs.

Features:

• Simultaneous heat and cool setpoint storage

• Pre-set temperature control

• LCD continuously displays setpoint and room temperature

This thermostat is intended for use with a low voltage system; do
not use this thermostat with a line voltage system. If in doubt
about whether your wiring is millivolt, line, or low voltage, have
it inspected by a qualified heating and air conditioning contractor
or electrician.

Do not exceed the specification ratings.
All wiring must conform to local and national electrical codes and

ordinances.
This control is a precision instrument, and should be handled

carefully. Rough handling or distorting components could cause
the control to malfunction.

! CAUTION

▲

To prevent electrical shock and/or equipment damage,
disconnect electric power to system at main fuse or
circuit breaker box until installation is complete.

• Backlit display when any key is pushed

• °F/°C convertibility

• Temperature range 45° to 90°F

• R, C, W, W2, G , Y and Y2 terminals

• Optional C terminal (Dual Power option)

• Setpoint storage in case of power loss

• 2 “AA” Energizer

®

alkaline batteries included

PRECAUTIONS

! WARNING

▲

Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.

Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will damage
thermostat and could cause personal injury and/or
property damage.

Thermostat installation and all components of the
system shall conform to Class II circuits per the NEC
code.

INSTALLATION

REMOVE OLD THERMOSTAT

1. Shut off electricity at the main fuse box until installation is

complete. Ensure that electrical power is disconnected.

2. Remove the front cover of the old thermostat. With wires

still attached, remove wall plate from the wall. If the old
thermostat has a wall mounting plate, remove the thermo­stat and the wall mounting plate as an assembly.

3. Identify each wire attached to the old thermostat using

the labels enclosed with the new thermostat.

4. Disconnect the wires from old thermostat one at a time. DO

NOT LET WIRES FALL BACK INTO THE WALL.

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 9797 Reavis
Road, St. Louis, MO, 63123-5398 for proper disposal.

ELECTRIC HEAT 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

switch on the thermostat base (see fig. 1) and switch it to the
ELECTRIC position. This will allow the thermostat to energize

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,
above).

2. Connect wires beneath terminal screws on base using

appropriate wiring schematic (see figs. 2 through 4).

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

Figure 1. Thermostat Base

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
remove the battery tag to engage the batteries.

If BATT is displayed, the batteries are low and should be
replaced with fresh "AA" Energizer® alkaline batteries. To
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 CONFIGU­RATION 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.

Fan Operation

If your system does not have a G terminal connection, skip to
Heating System.

1. Move fan switch to ON position. The blower should begin

to operate.

2. Move fan switch to AUTO position. The blower should

stop immediately.
