Mixing Control - Variable Speed

The Mixing Control 361 is designed to operate a mixing pump using Outdoor Temperature Reset. It can be used in applications ranging from in-floor radiant to commercial baseboard systems for Boiler Return Protection with full reset. This control regulates a single heating water temperature through Mixing Outdoor Reset. It provides mixing by speeding up or slowing down a single permanent capacitor (standard wet rotor) circulator, and provides control of the mix system pump.
