One period ends at the start time of the next period.
The end of one period may not be any closer to the
beginning of the next period than one 15-minute incre-
ment. Moving a start time too close to the next start
time results in the latter time being pushed ahead too.

advance to the SET TEMPERATURE, it will flash to show
that it may be edited.

program are Sa and Su together. This two day program
will repeat.
ADVANCED FEATURES
CALIBRATION OFFSET
Your thermostat is accurately calibrated at the factory
to within + 1°F. An offset value up to +5°F may be
added to the temperature value that the thermostat
measures. This may allow you to match this thermostat
to another.
To change this offset from its default value of 0:
1. Open the door on the front of the thermostat.
2. Rotate the dial to SET DAY/TIME.
3. Simultaneously press NEXT and HOLD. The
Temperature Offset value will flash.
4. The default value is 0 and in most cases should
remain untouched.
5. Use the UP/DOWN keys to adjust the offset value.
6. Return the dial to its RUN position to accept the new
value.
SOFTWARE RESET
Use this feature to make all settings and programs
return to their default values. Press and release [RESET]
button using a pen or pencil. It will perform a system
check and then returns all settings to their original
default values before initiating normal operation.
NOTE:
Pressing this button will overwrite your
program and install the default values of all
temperature programs and setup values into the
unit's nonvolatile memory. To ease reprogram-
ming later, record your thermostat's programs
and settings in the table provided at the page
bottom before using this button.
TEMPERATURE VARIATION / SWING
Your thermostat works by turning your heating or
cooling system on and off whenever the room temper-
ature 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, saving ener-
gy in most cases.
SWING ADJUSTMENT
This setting controls when the heating or cooling
turns on and off.
●
The Swing setting sets the temperature variation the
system allows above or below the set temperature
before turning on the heating or Cooling. To change
this value:
1. Rotate the SPEED DIAL
®
to RUN.
2. Press NEXT and HOLD simultaneously. The
Temperature section of the display shows a single digit
number between 1 and 9.
