Interruptor de presión Honeywell «C6065AH1020U»

Honeywell C6065AH1020U air pressure switch. High-precision air pressure control for forced draft burners. Honeywell C6065AH1020U air pressure switch is a precision differential pressure sensor (pressure switch) designed for air flow control in forced draft systems. The C6065AH series relay is a basic safety element for gas and oil burners, providing start-up lockout in case of insufficient pressure or absence of combustion air flow. If your burner fails to start, shuts down during the pre-purge stage, or the fan runs but ignition does not occur, the cause may be a failure or misadjustment of this relay. Installing an accurate original replacement ensures safe and stable equipment operation. Technical specifications: Parameter Value. Part numbers: C6065AH1020U, 534.676.025.
