•Backlit display
•LCD continuously displays setpoint and room temperature
•°F/°C convertibility
•Temperature range 45° to 90°F
•RC, RH, C, W, Y, G , O and B terminals
•Optional C terminal (Dual Power option)
•B and O terminals for single stage heat pumps (no auxiliary heat) or damper operation
•Setpoint storage in case of power loss
•2 "AA" Energizer® alkaline batteries included
PRECAUTIONS
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.
! 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 2895 Harrison Street, Batesville, AR 72501-2117 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 switch on the back of the thermostat (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.Removethepackingmaterialfromthethermostat.Gentlypullthe coverstraightoffthebase.Forcingorpryingonthethermostatwill 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 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 fireresistant 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 "LO BATTERY" 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.
