Features
- Boiler Rotation
- 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.
- Intelligent Control
- 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, it 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.
