Taco 563-2 – Strap-On Aquastat Temperature Control for Hot Water Circulation

The Taco 563-2 Aquastat is a strap-on surface temperature control designed to manage the operation of Taco circulators in domestic hot water systems. It activates the circulator based on pipe surface temperature, helping maintain water at desired temperature thresholds in recirculation applications.

This line-voltage controller uses a strap-mounted sensor to monitor pipe temperature and features fixed ON/OFF settings for reliable, energy-efficient operation. It is commonly used in systems where hot water recirculation is required to reduce wait times at fixtures and prevent water waste.
