Product Overview
A.J. Antunes 804111705 Dual Gas Pressure Switch
The A.J. Antunes 804111705 Dual Gas Pressure Switch monitors both high and low gas pressures in HVAC systems. During installation, a threshold for both high and low pressures are selected. This switch then monitors the gas pressure in the system, if the pressure drops below or exceeds above the low or high threshold, then the switch is activated. Once activated, the switch will shut off the system. This helps keep the HVAC equipment running properly.
For this part, if the system is shut down, the switch must be manually reset before starting up the equipment again.
