Description
The AERCO 61002‑5 is an OEM blocked inlet pressure switch used in AERCO commercial and industrial boilers and water heaters to monitor gas pressure conditions. This safety device detects when the inlet pressure drops below a specified negative threshold (about ‑4.5 inches of water column) and sends a signal to the control system to interrupt operation if a blocked inlet or low intake pressure condition occurs. It typically operates on 24 VAC and is part of the gas train safety controls that ensure proper combustion and prevent unsafe operation.
Key Features
- Valve senses negative inlet pressure conditions down to approximately ‑4.5″ WC to protect the system.
- Designed as an OEM blocked inlet pressure switch for AERCO boilers and water heaters.
- Operates on standard control voltage (typically 24 VAC).
- Contributes to safe combustion by shutting down operation when inlet pressure is unsafe or restricted.
- Compact switch assembly sized for gas train installations.
