temperature setting will return to its programmed value.

●

An OVERRIDE may be terminated by rotating the dial, switching the mode to OFF,
or initiating a HOLD.

●

Adjusting the set temperature to
its program value will also cancel an
OVERRIDE.

TEMPERATURE HOLD

HOLD may be used for manual
temperature control. HOLD is the
simplest means to set and maintain a fixed temperature. It allows you to set and
maintain a temperature Set Point indefinitely in Heat or Cool without concern for
programming. To initiate a HOLD:

●

Press and release HOLD.

●

After the Set Temperature begins to flash, adjust temperature as desired with UP or

DOWN keys.

TEMPERATURE SWING

A thermostat works by turning your heating or cooling system on or off whenever the
room temperature varies 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, but saves energy in most cases.

SWING SETTING

1. With the Dial in its RUN position, simultaneously press NEXT & HOLD.

2. Use the UP and DOWN keys to change swing.

3. Choices are 1 through 9. The default is 1.

4. Rotate the dial to the RUN position or press NEXT to finish.

SETUP OPTIONS

JUMPER SETTINGS

There are three jumpers and one switch. Each controls a setting corresponding to its
position.

5MIN/2MIN MINIMUM RUN TIME - JP3

The position of J3 sets the minimum length of time that the thermostat must remain
with Heat or Cool either on or off before it will automatically switch to the alternate On or
Off state. This feature prevents short cycling and provides compressor protection for
cooling units. Choices are 2 or 5 minutes.

TEMPERATURE DISPLAY FORMAT °F/C - JP2

The position of this jumper controls whether temperature is displayed in degrees F° or C°

TIME DISPLAY FORMAT 12/24 HR CLOCK - JP1

The position of this jumper controls whether time is displayed in 12 hour or 24 hour
Military Time format.

REPOSITIONING JUMPERS

To change a setting, the jumper must be repositioned and a HARDWARE RESET must
be performed. Note that as long as you press the Hardware Reset button (inside) and not
the Software Reset button (front), you will change settings and not lose your
program.These jumpers are located inside the thermostat on the rear of its circuit board.
To access them, remove the unit from the wall by pressing up on the thumb latch at the
bottom of thermostat and swinging the body out and away.

GAS/ELECTRIC SWITCH

This switch controls whether the thermostat requests the system fan to run when it is
in HEAT mode with the fan set to AUTO. Then with the switch set to GAS the fan is con-
trolled by the heating system itself and the terminal will remain inactive. With the gas
switch set to Electric (ELEC), the fan is controlled by the thermostat.

The table pictured below is also printed on the circuit board. The closed or shorted
position is that which covers both a jumpers pins. To prevent its loss in the open posi­tion, a jumper may be placed over one pin only.
After jumpers have been changed, press the HARDWARE RESET button for the changes
to take effect. See HARDWARE RESET

WARNING

Use Energizer®or DURACELL®Alkaline Batteries Only.

INSTALLING BATTERIES/ MAINTENANCE
