- ZS Zoning Pressure Switch Opened (High Pressure)

Equipment not specified:
Priority condition: Information Only-Dealer Zoning Pressure Switch Opened (high pressure). • Compressor pressure is above the specified limit. • Compressor is turned off. • Zoning will be restored once the high pressure switch closes. Occasionally we get this with an AC system and the fix is to just jump out the pressure switch terminals on the damper control module board.
