Description
Fixed set buffer temperature for standard heating
of the DHW cylinder
Fixed set buffer temperature for high heating of
the DHW cylinder (for increased drinking water
hygiene)
If the differential between the actual and set buf-
fer temperature is greater than this start differen-
tial, a demand is triggered.
If the differential between the actual and set buf-
fer temperature is smaller than this stop differen-
tial, the demand ends.
Description
Outside temperature at which the booster heater
backs up the heat pump
Value that is added to the set value of the exter-
nal heat generator
Waiting time before demand is issued to booster
heater
Amount of time the booster heater has to provide
an operating response
Description
Fixed set flow temperature for the heating circuit
("Fix")
If the average outside temperature for the day
falls below this value, the heating system is acti-
vated.
If the average outside temperature for the night
falls below this value, the heating system is acti-
vated.
