The Adaptor Plate 012 covers the paint ring left behind when replacing other thermostats, so that no patching or painting the wall is required. The 012 also allows a thermostat to be installed onto a single gang electrical box. The 012 package includes screws for mounting the adaptor plate and the device that attaches to it.

The Indoor Sensor 076 is designed to provide remote temperature sensing when connected to a compatible thermostat, or control. It can be used in installations that use a boiler control but want Indoor Temperature Feedback for increased efficiency and comfort. This product can be connected to a control to provide temperature sensing at any location where it is installed. An optional Adaptor Plate 007 is available which allows the indoor sensor to be installed onto a single gang electrical box.

The Universal Sensor 078 is a temperature sensor with a stiff jacketed cable, making it a perfect choice for easy installation into conduit or domestic hot water tank temperature wells. The sensor can also be strapped to a pipe to measure supply or return temperatures.

The Boiler Control 256 is designed to operate a single boiler using Outdoor Temperature Reset. It can be used in applications ranging from a single zone of baseboard to multiple zones of fan coils and baseboard. This control regulates a single heating water temperature through Outdoor Temperature Reset.

The Outdoor Sensor 070 provides accurate measurement of the outdoor air temperature. Many controls and thermostats can connect to the 070 to measure and display the outdoor temperature.

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 Boiler Control 260 is designed to operate a single boiler using Outdoor Temperature Reset. It can be used in applications ranging from baseboard or fancoils, to combination space heating and domestic hot water heating installations. This control regulates a single heating water temperature through Outdoor Temperature Reset and/or Domestic Hot Water control. It is capable of controlling a single on/off boiler and can receive both space heating and/or DHW heat demands.

The One Stage Setpoint Control 150 is designed to operate a single component of a heating or cooling system in order to maintain a set temperature. It can be used in applications ranging from heating a swimming pool to maintaining a constant slab temperature in a commercial car wash bay. This control regulates a constant setpoint water temperature for heating or cooling. The 150 is designed to operate a single relay (rated at 240 V, 8 A) to control a single device such as a boiler, pump, or valve.

The Universal Sensor 082 is a 10 k? temperature sensor designed to be strapped onto a pipe. It can be used with any tekmar control sensor input, but is most commonly used to monitor supply and return water temperatures. This product has a brass sleeve for fast response, a wide operating range, an indent to allow pipe strap on installation, and 8 ft (2.4 m) of 2-conductor wire.

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.
