With the default setting the microprocessor is al-
lowed to override and clear the A30 - "FAILED TO
RUN MIN TIME" or A31 - "FAILED TO START -
AUTO alarm(s) three consecutive times before the
override is locked out and no further restart at-
tempts will be allowed until the alarm(s) are cleared
manually.
The number of restart attempts allowed before the
override is locked out may be changed by entering
the desired number in this Sub-Configuration. Set-
ting this number too high may result in a discharged
or damaged battery if the unit never actually starts
or fails to run long enough to charge the battery
prior to shutting down again.
YES = Allows access to the IntelliSet menu using
the = key.
NO = Allows access to the IntelliSet menu using the
SELECT key.
Value to be used to calculate the lowest allowable
supply air temperature, when in Start-Stop Opera-
tion, in accordance with the formula "Set Point +
this value = coldest allowable supply air temperat-
ure". For example:
Fahrenheit: if the set point is 35°F and the Config-
uration value is set at -10°F the calculation is 35 +
(-10) = 25°F lowest allowed supply air temperature.
Celsius: if the set point is 2°C and the Configuration
value is set at -6°C the calculation is 2 + (-6) = -4°C
lowest allowed supply air temperature.
Value to be used to calculate the lowest allowable
supply air temperature, when in Continuous Opera-
tion, in accordance with the formula "Set Point +
this value = coldest allowable supply air temperat-
ure". For example:
Fahrenheit: if the set point is 35°F and the Config-
uration value is set at -10°F the calculation is 35 +
(-10) = 25°F lowest allowed supply air temperature.
Celsius: if the set point is 2°C and the Configuration
value is set at -6°C the calculation is 2 + (-6) = -4°C
lowest allowed supply air temperature.
When active, this logic indicates if temperature lim-
its regulating the exit of pulldown mode are modi-
fied or not.
ON = Unit will continue in High Speed until it
reaches set point.
OFF = Normal unit operation.
