• Start Delay: Before the compressor start, there is a
delay for the set time to ensure that process tem-
perature remains equal to or greater than the “Start
Temperature”.
• Stop Pressure: When the process temperature is
less than or equal to this setpoint, the compressor
will stop.
• Stop Delay: Before the compressor stop, there is
a delay for the set time to ensure that the process
