Option jumper positions. It then makes all settings and
programs their default values before initiating normal
operation.
N O T E: 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
reprogramming later, record your thermostat’s programs and
settings in the table provided before using this button. (See
Page 12.)
7.6 TEMPERATURE VARIATION / SWING
Your 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, saving energy in most
cases.
7.6.1 SWING 1 - 1st STAGE
This setting controls when the heating or cooling turns
on and off.
●
Swing 1 sets the temperature variation that the system
allows above and below the set temperature before
switching the heating or cooling unit on and off.
To change this value:
●
Rotate the
SPEED DIAL
®
to
ENERGY USAGE
●
Press
NEXT
and
HOLD
simultaneously. The
Temperature section of the display shows
SET TEMP
SWING
and
1
denoting that you are setting
SWING 1
.
The Time section flashes the current setting.
●
Select one of the 9 values from 025 to 225 with the
UP/DOWN
buttons. The smallest setting of 025 provides
the most accurate temperature control, and the system
will cycle on/off the most frequently. The largest setting
of 225 provides the widest temperature differential, and
the system will cycle on/off less frequently.
●
Return the
SPEED DIAL

RUN
7.6.2 SWING 2 - 2nd STAGE
This setting controls when the second stage of heating or
cooling turns on and off. It controls the temperature
variation the system allows above and below Swing 1's
limit before calling for a second stage. Once a second
stage is activated, it will remain on until the set
temperature has been reached.
To change this value:
●

7.7 DEAD BAND
When using Auto-Changeover, dead band provides a
disallowed temperature range between the maximum
heat set temperature and minimum cool set temperature.
dead band may be set from 1 to 6 degrees. With auto-
changeover active, dead band set to 3°F and heat set to
70°F the minimum allowed cool set temperature will be
73°F. If the cool set temperature is lowered, then the heat
set temperature will be lowered by the same amount
maintaining the 3°F dead band.
To change this setting:
●
Set

●

AUTO
●
Press
NEXT
and
COPY
simultaneously for 2 seconds.
The display shows

●
Use

. Or, after 30
seconds the unit will automatically revert to

8 SETUP OPTIONS
There are five jumpers; each controls a setting depending
on its position. Jumpers are located on the rear of the
thermostats circuit board. For reference there a table of
settings and jumper positions printed there as well. They
are described here from J3, the rightmost jumper, to J7,
the leftmost jumper.
8.1 MINIMUM RUN TIME J3
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 Delay prevents rapid
cycling of your system and provides equipment
protection for cooling units. Switch position OFF is a 5
minute delay, and ON is a 2 minute delay. 5 minutes is
the default setting, and is good for most applications. If
you feel that your system is trying to cycle more rapidly
than every 5 minutes, you may try the 2 minute setting.
8.2 CLOCK FORMAT J4
The time shown on the thermostats clock may be
displayed in 12 or 24-hour format. Set this option to your
preference.
