Deadband/Overlap:
The Deadband/Overlap is that per-
centage of the heating side of the proportional band
where the heating (output #1) and the cooling (output #2)
outputs are separated by a Deadband or where they
Overlap on a heat/cool controller. A value greater than
zero establishes a Deadband or area where neither the
heating nor cooling outputs are energized for more pow-
erful heating and cooling loads. A value less than zero
establishes an Overlap or area where both the heating
and cooling outputs are energized at the same time for
less powerful heating and cooling loads. Enter a value
based on the power of your heating and cooling loads as
well as the application’s efficiency in maintaining tight
heat/cool control.
Setting range: -50.0 to 50.0% of the heating proportional
band.
Not indicated without control output #2 option.

Balance:
Balance is used to pre-position the proportional
band with respect to setpoint. With Balance (MV Offset)
set at 50% the proportional band will be centered around
setpoint. To move the band left or right, decrease or
increase the balance setting respectively.
Setting range: 0-100%.

Anti-Reset Wind-up:
Anti-Reset is used to limit the range
where integration occurs. This helps in stabilizing a sys-
tem. With Anti-Reset at 100%, integration will occur
throughout the proportional band. With Anti-Reset set to
90%, integration will occur at 90% of the band above the
setpoint and 90% of the band below the setpoint.
Autotuning automatically sets Ar.
Setting range: 0-100% of full scale, set in E.U.
