AK2-SC 255 Reference Manual
Max Humidity or Max dewpoint: Control will be
based on the highest-reading of a group of sensors.
Average: Control will be based on the average of a
group of sensors.
Dewpoint 1-1 (etc.) Any single dewpoint sensor can
be selected.
Humidity 1-1 (etc.) Any single humidity sensor can
be selected.
(List box similar to the preceding; appears only when
using Calc Dewpt as the control strategy.)

(0.0 to 100.0) The control target in percent relative
humidity or dewpoint degrees depending on the strat-
egy chosen above.
(0.1 to 15.0) The differential forms a deadband above
and below the target in which no control actions are
taken. Dehumidification will be turned on at target plus
differential and turned off at target minus differential.
(0 to 60) (Not present when dessicant wheel is
configured) The number of minutes that must elapse
after target plus range is reached before the stage will
come on. There is one field for each stage.
(0 to 60) (Not present when dessicant wheel is
configured) The number of minutes that must elapse
after target minus range is reached before the stage
will be turned off. There is one field for each stage.
(0.0 to 100.0) If zone temperature is below this limit,
dehumidification will be disallowed.
