new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new

installations, follow the guidelines listed below.

1. Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and in a room that is

used often.

2. Do not install it where there are unusual heating conditions, such as: in direct

sunlight; near a lamp, radio, television, radiator, register, or fireplace; near hot water pipes in a wall;

near a stove on the other side of a wall.

3. Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room; or in

a draft from a stairwell, door, or window.

4. Hold the base against the wall, with the wires coming through wherever

it is convenient for wiring. Route the wires to below the terminal block.

Position the base for best appearance (to hide any marks from an old

thermostat). Attach the base to the wall with the two screws provided.

•

Temperature swing adjustment lets you fine-tune your system for maximum comfort and

economy.

A 4-minute minimum on/off time in COOL prevents your air conditioning system from being

damaged.

The thermostat can be powered either by a common wire from the 24Vac transformer with

two Energizer^®or DURACELL^®"AA" size alkaline batteries as backup or exclusively by two

Energizer^®or DURACELL^®"AA" size alkaline batteries.

• Your thermostat is a precision instrument. Please handle it with care.

• Turn off electricity to the appliance before installing or servicing thermostat or any part

of the system. Do not turn electricity back on until work is completed.

• Do not short (jumper) across electric terminals at control on furnace or air conditioner

to test the system. This will damage the thermostat and void your warranty.

• All wiring must conform to local codes and ordinances.

• This thermostat is designed for use with 24 volt and millivolt systems. The thermostat

should be limited to a maximum of 1.0 amps; higher amperage may cause damage

to the thermostat. If you are in doubt, call your utility company.

N O T E

Do not allow wires to touch each other or parts on thermostat. Wires must be

trapped between black spacer and brass terminal. Also, be sure to tighten securely

all terminal screws.

PROGRAMMING THE UNIT

You can change any preset times and/or temperatures to suit your

schedules for the weekday and weekend programs. Each period

(Morning, Day, Evening, and Night) is programmed for HEAT and for

COOL. A blank programming chart is provided for you to record

your temperature settings in that chart.

ADVANCED FEATURES

A thermostat works by turning your heating or cooling system on and off whenever the room

temperature varies a certain number of degrees from the set-point temperature. This variation is the

“swing.”

Your system should cycle on about 3 to 6 times per hour. A smaller swing number increases the

number of cycles, so room temperature is more constant. A larger swing number decreases the

number of cycles, to save energy in most cases.

HEAT and COOL may
