A setting must be made as to which storage tank (storage tank sensor)
has priority for charging. Charging of the lower-priority storage tank is
interrupted at regular intervals to check whether the temperature increase
at the collector can enable charging of the higher-priority storage tank.
Setting range: S2 or S3/default setting: S2
In systems with two storage tanks charging of the lower-priority storage tank
will never take place until this set temperature setpoint at the storage tank
sensor of the higher-priority storage tank is exceeded.
Setting range: from 0°C to 90°C/default setting: 40°C

The charging of the lower-priority storage tank is interrupted after the
settable time in order to check whether the collector can reach a temperature
level that will soon enable charging in the higher-priority storage tank. If
the conditions for charging the higher-priority storage tank or for continued
interruption are not met, then the charging of the lower-priority storage tank
is enabled again and interrupted again after the time set here in order to
consider the current temperature increase of the collector.
Setting range: from 5 to 90 minutes/default setting: 10 minutes
For precise setting of the charging priorities for systems with multiple
storage tanks, the necessary temperature increase of the collector at
which the interruption of the charging in the lower-priority storage tank is
extended by one minute is set here. The interruption is extended because
the temperature increase of the collector is expected to enable charging
in the higher-priority storage tank soon. If the rise in temperature falls
below the set value, then the charging of the lower-priority storage tank
is enabled again.
Setting range: from 1°C to 10°C/default setting: 3°C
