Description
Product Summary
The Johnson Controls P70AB-12C is a pressure switch from Johnson Controls, described by the manufacturer as: SPST pressure control 12"/80# differential adjustable 5/35# 1/4" flare 36" cap. It replaces P70AB-47 & P70AA-185.
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.
Before you order, match P70AB-12C to the part number on the part you are replacing or in your equipment's repair parts list, and confirm the voltage, size and connections match your equipment.
