A second temperature sensor offers an
improved utilisation of the DHW cylinder.
It is fitted below the top temperature sen-
sor.
This temperature sensor (lower) is used
as stop criterion for the once-only DHW
heating through the demand "max. DHW
volume" or in the switching stages
"Standard" or "Set temp. 2".
DHW heating is started with the switch-
ing times stages using the upper tem-
perature sensor, in case of max. DHW
volume using the lower temperature
sensor.
