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
