Your new White-Rodgers 5-Day/1-Day/1-Day 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:

•Separate 5-day (weekday), 1-day (Sat) and 1-day (Sun) programming with four separate time/temperature periods per day

•Simultaneous heat and cool program storage

•Preprogrammed temperature control

•Backlit display

•LCD continuously displays setpoint, and alternately displays time and room temperature

•Temperature override until next program period

•Manual program override (HOLD temperature)

•Temporary HOLD

•°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

•Program storage in case of power loss

•2 “AA” Energizer® alkaline batteries included

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 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.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 7).
