DHW heating to start DHW
heating by the solar thermal
system
6E:1

Setting range of differential
temperature in K
Maximum temperature DHW
6F:70
Max. DHW temperature limit
when heated by the solar
thermal system. DHW
is heated by the solar thermal
system up to this temperature.
If DHW is heated by a combi
tank, this temperature refers
to the first buffer tank
temperature sensor.
