Tekmar nine stage boiler control designed to stage multiple boilers using an outdoor temperature reset.

Tekmar indoor sensor designed to provide remote temperature sensing when connected to a compatible thermostat, or control.

Tekmar steam control used to operate a single steam boiler using an outdoor reset. It features an outdoor temperature reset, warm weather shut down, built-in programmable timer, and indoor temperature feedback.

Tekmar boiler control used to operate a single steam boiler using an outdoor reset. It is ideal for applications ranging from a single zone of baseboard to multiple zones of fan coils and baseboard. It is capable of controlling a single on/off boiler.

Tekmar 260 boiler control that operates a single boiler using outdoor temperature reset. 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.

Tekmar 261 boiler control that is designed to stage two on/off boilers using outdoor temperature reset. This control regulates a single heating water temperature through outdoor temperature reset and/or setpoint target control. It is capable of controlling (stage and rotate) up to two on/off boilers, or a single 2-stage boiler, as well as, the system pump.

Tekmar 263 boiler control that is designed to stage multiple boilers or operate a modulating boiler using outdoor temperature reset. This control regulates a single heating water temperature through outdoor temperature reset, setpoint, and DHW target control. It is capable of controlling (stage and rotate) up to two on/off boilers, a single 2-stage boiler, or one modulating boiler, as well as, the system pump.

Tekmar 265 boiler control that is designed to stage multiple modulating boilers using outdoor temperature reset. This control regulates a single heating water temperature through outdoor temperature reset and/or setpoint/DHW control. It is capable of controlling (stage and rotate) up to three modulating boilers by using a native 4-20 mA (or 0-20 mA) signal that can be converted to 2-10 V (dc) or 0-10 V (dc), as well as, the system pump.

Tekmar 274 boiler control that is designed to stage multiple boilers using outdoor temperature reset. This control regulates a single heating water temperature through outdoor temperature reset and/or setpoint/DHW target control. It is capable of controlling (stage and rotate) up to four on/off boilers, as well as, the system pump.

Tekmar 275 boiler control that is designed to stage up to four condensing or non-condensing, modulating or on-off boilers using PID staging to accurately maintain temperature. Water temperature is controlled by outdoor temperature reset for space heating applications or a fixed setpoint for domestic hot water (DHW) tank heating or industrial process heating applications. The control will also accept an analog 0-10 V (dc) signal from an energy management system (EMS) to control the water temperature. Boiler equal run time rotation, pump exercising, and stand-by system pump operation increase boiler plant reliability. This control is tekmarNet communication compatible allowing for internet connectivity using an optional Gateway 483.
