Description
The Taco Comfort Solutions 563-2 is a strap-on aquastat designed for precise temperature-based control in hydronic heating systems. Engineered to clamp directly onto 7/8″ OD pipe, this aquastat eliminates the need for a well or immersion fitting, making installation fast and straightforward.
With a fixed On setpoint of 95°F and an Off setpoint of 115°F, the 563-2 is ideal for applications such as circulator pump control, low-limit protection, and auxiliary equipment switching in residential and light commercial boiler systems. When water temperature drops to 95°F, the aquastat closes the circuit to call for heat or activate a pump; once the temperature rises to 115°F, it opens the circuit to shut down the controlled device.
