Unit provides separate
programming for every day
of the week- for both heating and cooling. You can override the programmed temperatures for as
little as one programming period or for an entire vacation.
• In cool weather, when the system switch is set to HEAT, the Unit will maintain cooler "set back"
room temperatures to save energy. It will then change to warmer "comfort" settings — all
automatically, at specified times during the day.
• In warm weather, when the system switch is set to COOL, the Unit will maintain warmer "set
back" room temperatures to save energy. It will then change to cooler "comfort" settings - all
automatically, at specified times during the day.
• A large liquid crystal display shows time, day of the week, and room and set temperatures.
It will remind you when the filter should be changed in your blower and track your system's energy
usage.
• Temperature swing adjustment lets you fine-tune your system for maximum comfort and
economy.
• 5/2 Minute Selectable Minimum Run/Off Time for Short Cycle/Compressor Protection.
• Two Energizer® or DURACELL® "AA" alkaline batteries (not included) are used to retain your
time and temperature programs.

• 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.

THERMOSTAT LOCATION
On replacement installations, mount the
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. Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.
5. Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open
door.
6. Do not install the unit until all construction work and painting has been completed.
7. This thermostat does not require leveling.
REMOVING THE OLD THERMOSTAT
Switch electricity to the furnace and air conditioner OFF; then
proceed with the following steps.
1. Remove cover from old thermostat. Most are snap-on types and
simply pull off. Some have locking screws on the side. These
must be loosened.
2. Note the letters printed near the terminals. Attach labels
(enclosed) to each wire for identification. Remove and label wires
one at a time. Make sure the wires do not fall back inside the
wall.
3. Loosen all screws on the old thermostat and remove it from the
wall.
MOUNTING THE UNIT ON THE WALL
1. Strip insulation 3/8 in. (9.5mm) from wire ends and clean off any corrosion.
2. Fill wall opening with non-combustible insulation to prevent
drafts from affecting the thermostat.
3. Press up on the button on bottom of thermostat and swing the
body away from the base and up to remove the body from the base.

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). An optional wall plate is included for covering old mounting
holes. Attach the base to the wall with the two screws provided.
C
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 7 electrical terminal screws.

TEMPERATURE SWING
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.

SMART RECOVERY
Your thermostat has the capability to turn the HEAT and AIR CONDITIONING ON in your home so that it
reaches your desired comfort temperature at the time you have programmed. For instance, if you have pro-
grammed your thermostat for 70° at 5:00pm, normally the thermostat will begin to heat your home at 5:00pm.
With SMART RECOVERY on, the thermostat will calculate the best time to turn the heat on so that the temper-
ature in your home reaches 70° by 5:00pm. It calculates the amount of time through experience and will get
more accurate as time goes by. To enable SMART RECOVERY, remove J4 on the back of the thermostat. Press
the small reset button on the front of the thermostat. IN RECOVERY will appear in the display when this feature
is bringing your home to temperature.
