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 TEMPERATURE 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:
When thermostat is set to “Manual” non-
programmable mode, all positions of the SET slide switch
will act like RUN.
NOTE:
There is no delay available when the thermostat is
manually turned up and down.
NOTE:
Event or Period Quantity feature is not accessible
during Manual Non-Programmable mode.
UP / DOWN BUTTONS:
The UP and DOWN buttons are used to control the set
temperature, or adjust any other on-screen items. An items
flashing, is the item currently being adjusted.
HOLD BUTTON:
This button activates and deactivates the manual
Temperature HOLD feature, which maintains a fixed set
temperature indefinitely without following a program routine.
COPY BUTTON:
This is used to copy temperature program items from one
day to the next. Also used to access the menu setup.
NEXT BUTTON:
This is used when setting items such as software options,
and temperature programs when they are flashing on the
screen. Pressing the NEXT button will cycle through which
item is flashing.
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.
