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 257 DHW Control is capable of operating a two-stage boiler, or two single-stage boilers, in order to maintain a constant domestic hot water temperature. This control from tekmar is an excellent way to ensure that your system's domestic hot water operations are efficient and economical.
When you are using the tekmar 257 DHW 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.
The tekmar 257 monitors the water temperature of your DHW tank. It uses this information to determine ideal boiler firing rates. By constantly monitoring conditions and continuously making adjustments, the tekmar 257 provides unparalleled comfort and efficiency.
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.
