To prevent electrical shock and/or equipment damage

disconnect electric power to system at main fuse or

circuit breaker box until installation is complete.

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

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY

BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE

PERSONAL INJURY AND/OR PROPERTY DAMAGE.

Your new White-Rodgers 5-Day/2-Day Digital Heat Pump Ther-

mostat 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) and 2-day (weekend) programming

with four separate time/temperature periods per program

• Simultaneous heat and cool program storage

• Preprogrammed temperature control

PRECAUTIONS

SPECIFICATIONS

• LCD continuously displays set point, and alternately dis-

plays time and room temperature

• Temperature override until next program period

• Manual program override (HOLD temperature)

• °F/°C convertibility

• Temperature range 45° to 90°F

• Eight terminals for single or two-transformer systems

• O/B terminal for heat pump systems

• Armchair Programming Capability

This thermostat is intended for use with a 24-volt system; do not

use this thermostat with a millivolt or 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.

Installation

Remove Old Thermostat

Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected.

Attach Thermostat Base to Wall

Remove the packing material from the thermostat.

Fan Option Jumper

Read the following information before clipping the non-electric heat jumper.

Energy Management Recovery (EMR)

The EMR feature allows, the thermostat's microcomputer to automatically calculate the time it will take to change the room temperature.

Wiring Diagrams

The following wiring diagrams show typical terminal identification and wiring.

Operation

O/B Terminal Switch Selection

The O/B switch on this thermostat is factory set to the "O" position. This will accommodate the majority of heat pump applications.

Armchair Programming

Armchair Programming is a unique feature that allows your thermostat to be programmed before being mounted on the wall.

Adjustable Anticipation

The first stage has anticipation that can be set to 2.5 or 4 cycles per hour for heating or cooling.

Check Thermostat Operation

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

Lockout Bypass Option

FOR QUALIFIED SERVICE TECHNICIANS' USE ONLY. OPERATORS SHOULD NOT USE THIS FEATURE DUE TO POSSIBILITY OF EQUIPMENT OR PROPERTY DAMAGE, OR PERSONAL INJURY.

Compressor Short Term Cycle Protection

This thermostat has a built-in short term (5-minute) time delay. During this 5-minute period, the thermostat will lock out the compressor to allow head pressure to stabilize.
