Buffer sensor 2 (BS2) Buffer sensor 2 (BS2)

As an option, the buffer tank can be equipped with the second buffer sensor (BS2) via the variable inputs, for stratified loading. The buffer is loaded through the active heat generator as soon as the higher temperature (of the two sensors) undershoots the setpoint value. Loading though the heat generator is terminated when the lower temperature (of the two sensors) has reached the setpoint plus the set buffer switching differential (stratified loading)

Buffer loading pump extended running time

When buffer loading of a buffer loading system is complete, an extended running time for the buffer loading pump can be configured via a parameter setting.
