Aquastat Relays

An aquastat relay combines three controls, an aquastat, a relay, and a transformer. All three components are mounted together. The purpose of the aquastat relay is to provide a place for most of the controls in a boiler system to be wired together for a convenient and secure setup. At DK Hardware, we offer a broad range of aquastat relays that helps control HVAC systems better. The Honeywell Home Boiler Aquastat Switching Relay is designed for use with an HVAC heating system. This immersion-type controller provides high limit protection while switching control of the oil burner and the circulator. The Honeywell Safety Aquastat are immersion-type devices for limiting or regulating the temperature of liquids in boilers, storage tanks, and other applications where temperature control is required. The Honeywell Safety Aqua-Stat Relays are an immersion-type controller that combines high limit protection with switching relay control of burner and circulator motors.
