Tekmar Controls

The tekmarNet® Thermostat 532 is a communicating thermostat designed for one stage hydronic heating systems. Simple up and down buttons and a display with large type make this thermostat easy to read and use. It has two auxiliary sensor inputs that can be assigned to measure room, floor, or outdoor temperature. An optional floor sensor protects the floor from overheating and enhance comfort. The 532 can be wired using two or four wires to connect to tekmarNet zoning controls, or can be installed as a stand-alone thermostat using three wires.

The tekmarNet® Thermostat 554 is a communicating touchscreen thermostat designed to operate one heating stage, one cooling stage, and a fan. The heating stage can be either hydronic or forced air and the cooling stage can operate an air conditioner. 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. The large touchscreen allows you to easily adjust 7-day programmable schedules and room temperature to optimize comfort and energy savings. The 554 can connect to tekmarNet controls using two or four wires or it can operate as a stand-alone thermostat using three wires.

The tekmarNet® Thermostat 557 is a communicating touchscreen thermostat designed to operate either: a hydronic radiant floor with a two stage heat pump (water-to-air or air-to-air) for heating & cooling and an emergency backup heating system; or two stages of heating and two stages of cooling. There are three auxiliary sensor inputs that can be used to measure room, floor, outdoor or duct temperature. The optional floor sensor allows precise heating of radiant floors. Relative humidity level can be measured and controlled using either the built-in or external humidity sensor. The large touchscreen display allows you to easily adjust 7-day programmable schedules and room temperatures to optimize comfort and energy savings. The 557 can connect to tekmarNet® controls using two or four wires or it can operate as a stand-alone device.

The Snow Melting Control 654 is designed to operate electric or hydronic equipment to melt snow or ice from any surface including driveways, walkways, patios, business entrances, parking ramps, loading docks, hospital entrances, helipads or car wash bays. The surface temperature for snow melting is controlled automatically to reduce operating energy costs. The 654 has an automatic start and stop function when used with the Snow/Ice Sensor 090 or 094. Automatic start with a timed stop is available when used with the Snow Sensor 095. The 654 can operate a dedicated hydronic boiler or a mixing device. Isolation relays are required to operate line voltage pumps. Electric systems require a separate GFCI and electrical relay contactor.

The 10K Temperature Simulator 002 is designed to be used to test any tekmar control using 10K thermistor sensors. This can be used to troubleshoot controls in the field, or to set up a simulation on a workbench and model control behavior. The main use of this product is to simulate control operation. There are 3 separate sensors that can be simulated using the rotary dials on the 002.

The Relay 003 is a 24 V (ac) coil DPDT (double pole double throw) relay that is used to isolate electrical loads and allow higher current ratings than the on board relays found on tekmar controls. It can be used in applications ranging from doubling the capability of a single output (e.g. energize a pump as well as provide a boiler demand from one output) to allowing a pump to be used that draws more than the control’s specified relay rating. This product uses a 24 V (ac) coil that once energized, closes 2 normally open contacts, and opens 2 normally closed contacts.

The Relay 004 is a 120 V (ac) coil DPDT (double pole double throw) relay that is used to isolate electrical loads and allow higher current ratings than the on board relays found on tekmar controls. It can be used in applications ranging from doubling the capability of a single output (e.g. energize a pump as well as provide a boiler demand from one output) to allowing a pump to be used that draws more than the control’s specified relay rating. The 004 relay uses a 120 V (ac) coil that once energized, closes 2 normally open contacts, and opens 2 normally closed contacts.

The 0 – 135 ? Converter 005 is designed to convert a 4 - 20 mA modulating signal from a control to a 0 – 135 ? resistance signal. It can be used in applications where a modulating boiler control is used to operate a boiler that requires a 0 – 135 ? signal.

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.
