AERCO Boiler and Water Heater 61002-5 Blocked Inlet Pressure Switch -4.5" WC

The AERCO Boiler and Water Heater 61002-5 Blocked intake Pressure Switch is a safety device that regulates the intake pressure in AERCO boilers and water heaters. As a Blocked intake Pressure Switch it prevents equipment from potential or malfunction by blocking operation in case of low intake pressure. This switch operates at 24 VAC and the pressure threshold of this switch is intended particularly to sense when the inlet pressure is below a certain safe level. The switch informs the control system of the boiler or water heater that it has to cease operation if the pressure goes down to. This interrupts the circuit and triggers the switch in HVAC system.
