After the harvest valve energizes, suction pressure
at the condensing unit increases.
1. The suction pressure exceeds the Low
Pressure Switch cut-in
(22 old and 35 old psig) and sends Line
voltage to the Contactor Coil.
2. The contactor closes and the compressor
starts.
NOTE: The INDIGO NXT CVD Control Circuit does NOT use a 24 volt Transformer. The
Contactor Coil is Line Voltage and is control by the Low Pressure Cut out as well as a
Solid State Delay on Break Timer.
