Description
Product Summary
The Johnson Controls P170AB-2C is a pressure switch from Johnson Controls, described by the manufacturer as: pressure control 20 /100# differential adjustable 7/50#. It replaces P70AA-104.
A pressure switch proves that air, water or refrigerant pressure is where it should be before allowing the equipment to run. On furnaces it proves the inducer's draft; on boilers and steam systems it controls or limits the operating pressure. Replace a switch that does not close with the correct pressure applied, or that opens and closes erratically. Check hoses, ports and venting first.
