Tekmar Controls

The Thermostat 518 accurately controls the room temperature for a hydronic heating zone using Pulse Width Modulation (PWM) technology. Simple up and down buttons and a display with large type make this thermostat easy to read and use. The 518 automatically detects a single auxiliary sensor to measure either outdoor, floor or remote room temperature. This easy to install thermostat is a direct replacement for tekmar Thermostats 507 and 508. An optional Adaptor Plate 012 is available which allows the thermostat to be installed onto a single gang electrical box.

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 Radiant Thermostat 519 accurately controls the room and/or floor temperature for a hydronic heating zone using Pulse Width Modulation (PWM) technology. Simple up and down buttons and a display with large type make this thermostat easy to read and use. A Slab Sensor 079 is included to measure floor temperature to protect the floor from overheating and enhance comfort. This easy to install thermostat is a direct replacement for the tekmar Thermostat 509. An optional Adaptor Plate 012 is available which allows the thermostat to be installed onto a single gang electrical box.

The Steam Control 279 is designed to operate a single steam boiler using Outdoor Temperature Reset. It can be used in single pipe steam applications as well as applications using a tankless DHW coil. This control regulates the on time of a steam boiler through Outdoor Temperature Reset control. It is capable of controlling a single on/off steam boiler.

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.

The Slab Sensor 079 is commonly used for floor temperature sensing in floor heating applications. The thin casing allows for retrofit installation between tile spaces if necessary. This sensor is designed to provide a thermostat with the ability to maintain a minimum slab temperature, or help to limit the maximum slab temperature.
