NOTE:
Offset is the difference between the temperature that is actually being sensed and what is displayed to ensure
proper product temperatures.
Example: Set point 34, 6, controller needs to sense 28F before the unit will turn off.
Delay:
Control has a programmed time delay on temperature rise to show a stabilized temperature within the
refrigerated space.
Example: Set point 34F, unit cycles off, consumer opens the door, rather than have the temperature immedi-
ately shoot-up, it is delayed and will continue to show 34F until the delay time elapses. Meanwhile the
controller is sensing actual temperature and will turn on when it senses set point plus hysteresis.
