For nearly three decades, tekmar has been providing zoning and control solutions for a variety of heating and cooling applications. Products made by tekmar can improve the efficiency and comfort delivered by almost any system. The tekmar 268 Boiler Control controls a single water temperature. It is equipped to operate a system pump and as many as nine boilers in order to satisfy heating demands in a hydronic system. You may add boiler pumps instead of boilers if it suits your system. The 268 Boiler Control also provides setpoint control, and DHW control and pump operation is available if setpoint control and the ninth relay are not in use. This control possesses several energy saving features, including outdoor temperature reset, to make your system more economical.
By monitoring system and outdoor temperatures, the tekmar 268 is able to make intelligent decisions about system operation. This includes adjusting supply temperatures based on outdoor conditions and providing boiler protection by monitoring and maintaining a minimum return water temperature. With the wide variety of operating modes and equipment it supports, the tekmar 268 is sure to make your system operate more efficiently, without sacrificing comfort.
The tekmar 268 allows you to designate a setback period when your home or business is unoccupied, reducing the water temperature to limit energy waste.
Warm Weather Shutdown
A warm weather shut down temperature may be programmed to prevent your system from running when it in unnecessary or untenable.
Proportional, Integral, Derivative (PID) Staging Mode
In PID mode, an advanced algorithm weighs many variables, including sensor temperatures, when making operation decisions. PID reduces short-cycling, improves efficiency, and prevents temperature drops in your system.
When you are using the tekmar 268 Boiler Control with two boilers, it will take each boiler's cumulative run time into account when deciding which boiler will fire first. This prevents one of your boilers from being overused.
