The larger the Modulating Cooling Proportional Window, the smaller
the signal adjustment per Time Period will be for each ºF the supply air
is from the Active Supply Air Temperature Setpoint. The Time Period is
the delay before another signal increase or decrease can be made and is
user-adjustable. Short Time Periods may cause hunting of the Modulat-
