Control Loop (1 to 4)
Cool Hysteresis **
Set the control switch-
ing hysteresis for on-off
control. This deter-
mines how far into the
“on” region the process
value needs to move
before the output turns
on.

Dead Band **
Set the offset to the
proportional band.
With a negative value,
both heating and cool-
ing outputs are active
when the process value
is near the set point.
A positive value keeps
heating and cooling
outputs from fighting
each other.
