Heat Hysteresis
Set the control switching
hysteresis for on-off con-
trol. This determines how

to move before the output
turns on.

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