Cool Hysteresis
Set the control switch-
ing hysteresis for on-off
control. This determines
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 out-
puts from fighting each
other.
