Tekmar Controls

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.

The Universal Reset Control 374 is designed to operate all of the mechanical equipment in a residential hydronic heating system. It can be used in applications ranging from a single zone of baseboard with an on/off boiler to multiple fan coils, low temperature staple up zones, low temperature in-slab radiant zones, domestic hot water, and 2 on/off boilers. It regulates up to three space heating water temperatures through Outdoor Temperature Reset. It is capable of controlling up to 2 on/off boilers, up to 2 mixing devices (either variable speed pumps or floating action mixing valves), and Domestic Hot Water or setpoint loads.

The 3-Way Brass Mixing Valve 711 is used to mix supply water from a hydronic source with water returning from a system. It is designed for use in either closed loop or open loop hydronic systems. This 3-way valve has standard female NPT threads, as well as a maximum leak through rate of 1% to allow for water expansion during temperature changes. The valve position can be manually set using the handle. An Actuating Motor 741 can be used to automatically operate the valve.
