Tekmar Controls

The Mixing Expansion Module 440 is designed to operate a mixing device within a hydronic heating system as part of a tekmarNet® control system. It is capable of controlling a mixed system pump and a 24 V floating action mixing valve or a wet rotor circulator for variable speed injection.

The Snow Melting Control 680 is designed to operate electric or hydronic equipment to melt snow or ice from any surface including driveways, walkways, business entrances, parking ramps, loading docks, hospital entrances, helipads and car wash bays. The 680 communicates with Building Automation Systems using BACnet® or Modbus® for alert notification, remote monitoring and adjustment capability. It uses a tekmar Snow/Ice Sensor 090 or a Snow Sensor 095 to automatically detect snow or ice on the snow melting slab. Up to two snow/ice sensors can be installed, thereby increasing detection area and providing backup redundancy in the case of sensor failure. Upon detection of snow or ice, the 680 operates an electric heating cable, a single hydronic condensing or non-condensing boiler, or a steam valve to provide heat to the snow melt load. The 680 provides boiler return protection by operating a mixing valve or variable speed injection mixing. Monitoring of energy consumption is possible when it is connected to an optional flow sensor.

The 3-Way Brass Mixing Valve 710 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.

The Actuating Motor 741 is a 24 V floating action actuator designed to operate all tekmar brass mixing valves (710 to 724). It receives a 24 V open or close signal, which causes the motor to open or close the valve. It provides 6 N·m (53 in·lbs) of torque over a 90° rotation. This product rotates its output shaft whenever 24 V (ac) is applied between either the counter clockwise or clockwise terminals and the Com terminal. It is compatible with any control having a 24 V (ac) floating output.

The Adaptor Plate 007 allows for installation of the smaller tekmar devices onto a 2” x 4” electrical box. The adaptor plate can be mounted vertically or horizontally and is designed to allow wiring to feed through in any position. Included with the adaptor plate are surface painted screws for mounting to the electrical box, and screws to mount the device being used to the plate.
