Tekmar Controls

The tekmarNet® 4 User Switch 479 is a simple 3 button switch that provides an easy way to override system temperatures. This user switch is a must have for any tekmarNet® system. Using tekmarNet® 4 to communicate with any other compatible tekmarNet® devices, the 479 User Switch allows the owner to override their entire tekmarNet® system, and offers the potential for significant energy savings. With the push of a button, the user can place all thermostats and boiler controls into an “away” state and take advantage of saving energy when the building is not being used.

The tekmarNet® 4 User Switch 480 is a simple 3 button switch that provides an easy way to override system temperatures. With the push of a button, one can put all thermostats and boiler controls into an “unoccupied” or “away” state and take advantage of saving energy when the building is not being used. The buttons on this product are also programmable, allowing the user to experience scenes within their system. The 480 has three demand inputs that can provide access to tekmarNet® 4 scenes or setpoint devices from a telephone switch, home automation, or security systems.

The Programmable Thermostat 521 is designed for three different modes of operation: single stage heating, two stages of heating with a fan, or one stage of heating and one stage of cooling with a fan. Two auxiliary sensors may be added to measure the floor, outdoor or room temperature. A Slab Sensor 079 is included to measure floor temperature to protect the floor from overheating and enhance comfort. The programmable schedule supports either a 7 day or 24 hour schedule with 2 or 4 events per day. A permanent temperature hold button overrides the programmable schedule. An optional Adaptor Plate 012 is available to allow the thermostat to mount onto a single gang electrical box.

The tekmarNet® thermostat 552 is a communicating touchscreen thermostat designed for hydronic heating systems. The extra large touchscreen display allows you to easily adjust 7-day programmable schedules and room temperatures to optimize comfort and energy savings. It operates a single zone of heating and has two auxiliary sensor inputs that can be assigned to measure room, floor, or outdoor temperature. An optional floor sensor allows precise heating of radiant floors by controlling the floor temperature and maintaining the desired room air temperature. Alternatively the room air temperature sensor can also be disabled to solely maintain a minimum floor temperature. The 552 can be wired using 2 or 4 wires to connect to tekmarNet® zoning controls, or can be installed as a stand-alone thermostat using 3 wires.

The tekmarNet® Thermostat 553 is a communicating touchscreen thermostat designed to operate two heating stages, one cooling stage, a fan and relative humidity. The heating stages can be hydronic, forced air or a single stage heat pump. The cooling stage is either an air conditioner or heat pump. There are two auxiliary sensor inputs available to measure room, floor, outdoor, coil or duct temperature. The optional floor sensor allows precise heating of radiant floors by controlling the floor temperature and maintaining the desired room air temperature. Relative humidity level can be measured and controlled using the built-in humidity sensor. The large touchscreen allows you to easily adjust 7-day programmable schedules and room temperature to optimize comfort and energy savings. The 553 can connect to tekmarNet® controls using two or four wires or it can operate as a stand-alone device.

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.
