Tekmar 356 Mixing Control - Variable Speed, 120V Relay

The Mixing Control 356 is designed to operate a mixing pump to control the temperature in a hot water heating system using Outdoor Temperature 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 Temperature Reset. It provides mixing by speeding up or slowing down a single permanent capacitor (standard wet rotor) circulator. Features include: Advanced setting to fine-tune building requirements, automatic boiler differential, boiler load reset, CSA C US certified, outdoor temperature reset, quick setup, test sequence to ensure proper component operation, user comfort adjustment to increase or decrease building space temperature, variable speed pump control and warm weather shut down.
