TUNING MENU
Prop Band
Generates a fire rate based on the error that exists
between the setpoint temperature and the actual
outlet temperature. If the actual error is less than
the proportional band setting (1 to 120°F), the fire
rate will be less than 100%. If the error is equal to
or greater than the proportional band setting, the
fire rate will be 100%. Default is 70°F.
Integral Gain
This sets the fraction of the output, due to setpoint
error, to add or subtract from the output each
minute to move towards the setpoint. Gain is
adjustable from 0.00 to 2.00. Default is 1.00.
Derivative Time
This value (0.0 to 2.00 min.) responds to the rate of
change of the setpoint error. This is the time that
this action advances the output. Default is 0.0 min.
Reset Defaults?
Allows Tuning Menu options to be reset to their
Factory Default values.
