Hysteresis Dhw Temperature Heat Pump - Viessmann VITOTRONIC 200 Service Instructions Manual

6007 Hysteresis DHW temperature heat pump

The set value determines at what deviation from the
current set temperature ("Set DHW temperature
6000" or "Set DHW temperature 2 600C") DHW
heating with the heat pump starts.

Note
Set a lower value for "Hysteresis DHW temperature
heat pump 6007" than for "Hysteresis DHW temper-
ature booster heater 6008". Otherwise the proportion
of DHW heating provided by the electric heater will
increase.
