A high side diverter array is coupled to at least one of the plurality of automated valves. A low side diverter array is coupled to at least one of the plurality of automated valves. A vent side diverter array is coupled to at least one of the plurality of automated valves. A pressure differential transmitter is coupled to the high side diverter array and the low side diverter array. A high side bleed solenoid is coupled to a high side of the pressure differential transmitter. A low side bleed solenoid is coupled to a low side of the pressure differential transmitter. A vent side bleed solenoid coupled to a vent side diverter array. A plurality of bypass solenoids is coupled to the high side bleed solenoid, the low side bleed solenoid and the vent side bleed solenoid.
