O. Thermostat Setup Options
Setup options for how the thermostat will function are
performed using a menu on the display screen.
TO ACCESS THE SETUP MENU:
Move the System Mode Switch into the OFF position,
and then hold down the COPY button for approximately 5
seconds until the screen changes. The menu will always
start with item #01, and is advanced to each following item
by a single press of the NEXT button. The options for each
item are changed using the
UP or
DOWN buttons.
ITEM #01 (CLK = CLOCK FORMAT):
• 12Hr, default: This displays the clock times using
standard AM and PM values.
• 24Hr: This displays the clock times using the military-time
format (example 22:00 hours, without using AM or PM).
ITEM #02 (TMP = TEMPERATURE SCALE):
• F, default: Shows all temperature values in Fahrenheit.
• C: Shows all temperature values Celsius.
ITEM #03 (PROGRAMMING STYLE):
• 7 Day, default: This style uses a separate program
routine for each of the 7 days in the week.
• 5/2 Day: This style uses a weekday program routine
for Monday, Tuesday, Wednesday, Thursday, Friday,
and a separate weekend program routine for Saturday
and Sunday.
• Manual Non-Programmable: In this setting, there are
no program routines for the thermostat to follow and
the temperature control will be set only by the UP and
DOWN buttons on the front panel.
ITEM #04 (PERD = EVENT OR PERIOD QUANTITY):
• 4P, default: Thermostat uses four Events per day (called
MORN, DAY, EVE
, and
NITE).
• 2P: The thermostat uses two Events per day (called DAY
and
NITE).
NOTE:
Event or Period Quantity feature is not
accessible during Manual Non-Programmable mode.
NOTE
: This delay does not happen when the thermostat
is manually turned up and down.

ITEM #08 (TEMPERATURE DIFFERENTIAL):
• The thermostat works by turning your heating system on
and off whenever the room temperature varies from the
desired set-point temperature.
• Use the UP/DOWN buttons to change the number value
between 1 and 9. Generally your system should cycle
on about 3 to 6 times per hour. A smaller differential
number makes the system cycle more frequently, so the
room temperature is more precise and constant. A larger
differential number will make the system remain on for a
longer duration each time and decreases the number of
cycles per hour.
• Default is set to 4.
P. Thermostat Operation Instructions
SET DAY AND TIME:
Place the SET switch into the DAY/TIME position. With the
day flashing press UP or DOWN to set the day or the week.
Press NEXT and the clock time will start flashing. Use UP or
DOWN to set the time; verify the AM/PM indicator is correct.
Return the SET switch to RUN position when finished.
HEATING:
Basic operation of the thermostat can be obtained with
the SET switch in the RUN position. The temperature
can be adjusted using the UP and DOWN buttons.
When the thermostat is first powered on, it will follow
a default temperature routine that is preset from the
factory
(Table 13.1)
.
ITEM #07 (DLAY = DELAY TIME):
• 5, default: Thermostat waits 5 minutes before turning
the system back on after it was last run. This internal
delay prevents the appliance from turning on too quickly
after shutting down. The 5 minute setting is fine for most
applications.
• 2: Same operation as above but reduced to 2 minutes
between state changes.
LCD DISPLAY BACKLIGHT:
The display screen is lighted to assist viewing at nighttime,
or in locations with low light levels. Press any button on the
front panel to activate the approximate 10 second backlight.
TEMPERATURE OVERRIDE:
While thermostat is in RUN mode, the set temperature
can be temporarily changed by pressing UP or DOWN.
The temporarily changed set temperature will return to
the programmed value stored in memory when start time
of the next upcoming scheduled event is reached (MORN,
DAY, EVE, OR NITE). While the temporary changed set
temperature is in effect, the word OVERRIDE will be shown
on the display screen. To cancel, move TEMPERATURE
switch to OFF and back to HEAT again.
