Description for Tekmar 256

The Tekmar 256 Boiler Control is a microprocessor-based control designed to regulate the supply water temperature from a single boiler based on the outdoor temperature. To avoid boiler short cycling and large temperature swings, the 256 is able to continuously adjust the boiler differential. The Tekmar 256 includes control functions such as Warm Weather Shut Down (WWSD) and Minimum Boiler setting. The control has a liquid crystal display (LCD) that normally displays the Boiler Supply temperature, but can display other temperatures and settings.
