Parameters
Hysteresis**
Charging temperature boost***
Max. charging temperature
Lag of storage tank charging pump
* Parameters serve as limitation of the adjustment range for the DHW temperature to be set
at the rotary switch
** Deactivation value T = DHW temperature + hysteresis
*** Charging temperature T = DHW temperature + charging temperature boost
