The Mixing Control 360 is designed to operate a mixing valve 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 controls the mixing by opening or closing a floating action type mixing valve actuator (3 or 4 way valves), and also provides control of the mix system pump.
