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.

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.

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.
The Unit is protected against normal static
electric discharges. However, in extremely
dry weather you should touch another
metal object before the Unit to avoid
potential loss of programs.

Installation is now complete. Be sure to turn the power
back on to your heating and /or air conditioning system. If this is the first time you are installing batteries,
the thermostat will display “SUN 12:00 AM”. Within 90 seconds the thermostat will begin to display the
room temperature alternately with the time. To correct the display, see “Setting the TIME and DAY,” after
