Hysteresis/Hysteresis booster heater
Note
The value selected for "Hysteresis"
should be higher than the expected
temperature drop due to heat losses
in a single night (approx. 5 K).
A lower value for "Hyst. booster hea-
ter" increases the proportion of elec-
trical DHW heating, i.e. the system
efficiency drops.
