The Mixing Control 356 is designed to operate a mixing pump to control the temperature in a hot water heating system using outdoor
reset. It can be used in applications ranging from in-floor radiant to commercial baseboard systems for boiler protection with full reset.
This control regulates a single heating water temperature through outdoor reset. It provides mixing by speeding up or slowing down
a single permanent capacitor (standard wet rotor) circulator.

This control is designed to mount on a 2” x 4” electrical box. This control is designed to operate permanent capacitor, impedance
protected (standard wet rotor type) or equivalent pump.
