OUT2 LED
The orange OUT2 energizes whenever the process temperature is two degrees (2
°F/ºC)
or more above the To Process set point. The compressor then comes on and runs until
the temperature at the To Process thermocouple is two degrees (2
°F/ºC) below the set
point.
This +2°F/ºC control set point is factory-set for proper compressor operation. Changing
it is not recommended without consulting the AEC Service Department.
