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.
