"DHW hysteresis 6007"
"Booster heater hysteresis 6008"
Cylinder temperature hysteresis for
starting and stopping DHW heating.
The set value determines the deviation
from the set DHW cylinder temperature
("Cylinder temperature DHW 6000") at
which DHW heating is started and stop-
ped. Parameter "DHW hysteresis
6007" relates to DHW heating with the
heat pump. Parameter "Booster heater
hysteresis 6008" specifies the hystere-
sis for heating with the instantaneous
heating water heater (accessory).

Note
■ The value selected for "DHW hyste-
resis 6007" should be higher than the
expected temperature drop due to
heat losses while the heating circuits
are in reduced mode (approx. 5 K).
■ A lower value for "Booster heater
hysteresis 6008" increases the pro-
portion of DHW heating with the boos-
ter heater.
■ Observe setting for "DHW with e
heating 6015".
