Aquastat Relays
Available1 product
Aquastat relays are thermostat-based relays that help maintain the correct water temperature in hydronic heating systems by turning the heating components on and off. Depending on their configuration, they can act as a high limit, low limit, or both. Some units feature additional contacts that control the circulating pump.
Spud Size
Triple Function
Triple-function aquastats control hydronic heating systems by keeping the working fluid in the desired temperature range. They activate the boiler when the temperature gets too low and turn it off when the upper limit is reached. Additionally, they can turn on the circulating pump when the trigger temperature is reached.
