TEKMAR 155 DIFFERENCE SETPOINT CONTROL

The Tekmar 155 Difference Setpoint Control is a microprocessor-based difference setpoint control intended for solar and wood stove or other intermittent heat source applications. The Tekmar 155 Difference Setpoint Control is a microprocessor based control that allows the transfer of heat from a source to a storage tank whenever the temperature difference between the two is greater than the selected DT setpoint. Additional setpoints are also included in the Tekmar 155 to help prevent the storage tank from overheating or the source from freezing. Both drainback and draindown systems can be used with the Tekmar 155 control. Several displays provide a variety of useful information. The control can display the Maximum and Minimum temperatures measured by both the Storage and Source sensors as well as the total heat transferred from the source to the storage.
