When set to “GAS”, the blower fan is controlled solely
by the heating
system itself. Systems that would typically use the “GAS” setting would
be: natural gas, propane, or oil furnaces, and boilers.
NOTE: If your blower fan does not operate properly
after installation, try
moving the Gas / Electric option to the "Electric"
setting.
When set to “ELEC”, the blower fan is controlled directly by the
thermostat. This setting is required for heating systems that do not control
their own fan, such as HEAT PUMPS, and units that only have an electric-
resistive heating element as the heat source.
B/0 CIRCUIT BOARD OPTION (FOR HEAT PUMP APPLICATIONS): This
setting is a plastic shorting cap which determines
the operation of the
shared B/0 wire terminal connection. This jumper must remain installed
for a Heat Pump system to be able to provide heating and cooling as
needed, and the majority of heat pumps today use the
default “0” setting.
The symptoms that will occur if this setting is not
correct will be: heating
while in cool mode, and cooling while in heat mode.
When this is set to “0" (factory default), the shared B/0 terminal will be
turned on while in COOL mode, and off in HEAT mode.
When this is set to “B” (which is needed for some Rheem, Ruud, and Bard
heat pumps), the shared B/0 terminal will be turned on in HEAT mode, and
off in COOL mode.

FRONT PANEL CONTROLS:
HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch
to HEAT to control your heating system,
and COOL to control your cooling system. The OFF position
will disable both the heating and cooling
units.
AUTO / ON, FAN MODE SWITCH: When in AUTO, the blower
fan (If present in your system) will cycle on
and off only while heating or cooling. In the ON position, the blower fan will run constantly at all times
with or without a demand for heating or cooling.
SET BUTTON: This button is used to access the temperature program settings when in heat or cool
mode, and for adjusting the day and clock while in off mode.
NEXT BUTTON: This is used when setting items such as
software options, and temperature programs.
When items on the screen are flashing during adjustments, pressing the NEXT button will cycle through
which item is flashing.
HOLD BUTTON: This button activates and deactivates
the manual Temperature Hold feature, which
maintains a fixed set temperature indefinitely without following a program routine. This button is not
used when ITEM #02 below is set to “3” for manual non-programmab le.
UP / DOWN BUTTONS: The UP and DOWN buttons are used
to control the set temperature, or adjust any
other on-screen items. Typicaliy, an item that is flashing can currently be adjusted.
SYSTEM CONFIGURATION AND SETUP OPTIONS:
Setup options for how the thermostat will function, along with choosing your particular system type, 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 hoid
down the SET 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 (TEMPERATURE SCALE):
[1] (default) Shows all temperature values in Fahrenheit.
. .[2] Shows all temperature values in Celsius.
ITEM #02 (PROGRAMMING STYLE):
[1] (default) 5/2-Day Programming. This style uses a weekday program routine for Monday, Tuesday,
Wednesday, Thursday, Friday, and a separate weekend program routine for Saturday and Sunday.
[2] 7-Day Programming. This style uses a separate program routine for each of the 7 days in the week.
[3] 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 #03 (PERIOD QUANTITY):
[1] (default) 4-Periods. Thermostat uses four periods per day (called MORN, DAY, EVE, and NITE).
[2] 2-Periods. The thermostat uses only two periods per day (called DAY and NITE).
ITEM #04 (MAXIMUM HEAT SET TEMP LIMIT):
[1] (default) Limit 90F (32C). The maximum heating set temperature is 90F (32C) degrees with no heat
mode temperature restrictions.
[2] Limit 80F (27C). The maximum heating set temperature is 80F (27C) degrees.
[3] Limit 70F (21C). The maximum heating set temperature is 70F (21C) degrees.
[4] Limit 60F (16C). The maximum heating set temperature is 60F (16C) degrees.
ITEM #05 (MINIMUM COOL SET TEMP LIMIT):
[1] (default) Limit 45F (7C). The minimum cooling set temperature is 45F (7C) degrees with no cool
mode temperature restrictions.
[2] Limit 55F (13C). The maximum cooling set temperature is 55F (13C) degrees.
[3] Limit 65F (18C). The maximum cooling set temperature is 65F (18C) degrees.
[4] Limit 75F (24C). The maximum cooling set temperature is 75F (24C) degrees.
ITEM #06 (SYSTEM / EQUIPMENT TYPE):
[1] (default) Fn=Furnace. This is for the majority of heating systems such as a natural gas furnace or
hot water boiler, that are not Heat Pump systems.
[2] HP=Heat Pump. Use this setting if you have a Heat Pump system (which uses the outdoor unit as
the primary heat source). The presence of either an “0” or “B” wire on your previous thermostat would
typically indicate you have a heat pump system. This thermostat is NOT compatible with heat pumps
r- which also have an electric heating element as a backup heat source (called Auxiliary / Emergency
^ Heat). IMPORTANT: When set to “2" for HP, the circuit board Gas/Electric option must also be set to
“ELEC”, as described earlier in the “COMPLETE THE INSTALL” section.
ITEM #07 (DELAY TIME):
[1] (default) 5 Minutes. Thermostat waits 5 minutes before turning the system back on after it was last
run. The 5 minute setting is fine for most applications, and provides equipment protection by
preventing rapid cycling.
[2] Same operation as above, but reduced to 2 minutes between state changes if desired.
ITEM #08 (TEMPERATURE SWING):
[1] (default) This is the tightest control, which is plus/minus 0.25F (0.14C) degrees from the target set
temperature.
[2 through 9] These alternate values make the temperature control wider with more variation. Each
incremental setting number adds an additional 0.25F (0.14F) degrees onto the initial setting. [9] is the
widest control setting, which is plus/minus 2.25F (1.25C) degrees from the set temperature.
ITEM #09 (TEMPERATURE CALIBRATION):
[0 (zero)] (default) At zero, there are no changes made to the base room temperature measurement.
The adjustment is from as low as subtracting -5F (-3C) degrees from the room temperature, to as high
as adding +5F (+3C) degrees to the room temperature. The internal temperature sensor is accurately
calibrated at the factory, and in most cases this setting should not need to be altered.
