An anti-short cycle delay (ASCD) is utilized to prevent operation of a compressor too soon after its previous run. The ASCD is initiated on unit start-up and on any compressor reset or lockout. The Simplicity™ control board monitors the following inputs for each cooling system: • A high-pressure switch is factory installed to protect against excessive discharge pressure due to a blocked condenser coil or a condenser fan motor failure. During cooling operation, if a high-pressure limit switch o

PRE-PURGE The control board monitors the low pressure switch and ensures it remains closed during pre-purge. If the pressure switch opens, the control goes back to pressure switch proving mode. The control waits for a 15 second pre-purge period, then begins the ignition trial IGNITION TRIAL PERIOD The control board energizes the pilot gas valve and spark outputs for an 85 second Ignition trial. The control de-energizes the spark when flame is sensed and enters a flame stabilization period. If fl
