switched off when either the water temperature measured at sensor SF2 has reached the
'Max.storagetanktemperature'orwhenthesolarcollectortemperaturerisesabove120°C.
The times-of-use of the DHW circuit do not affect the operation of the solar system.
After the key number 1999 has been entered, the operating hours of the solar pump are dis-
played in extended information level.

In this case, the controller applies priority operation, if necessary with intermediate heating.
