Charging prio storage tank (3822)
If several heat exchangers/indirect coils are tied into the system, the heat­
ing sequence for the connected cylinders can be determined by setting the
heating process.
None: Every storage tank is charged alternately with a temperature in­
crease of 5 °C, until the setpoint has reached level A, B or C (tab. 1).
Once all setpoints have been reached, the setpoints of the next level are
applied.
Hot water storage tank: The DHW storage tank is charged as priority
during any heating with solar energy at any level (A, B or C). Other con­
sumers with the same level will only be charged afterwards. Once all
setpoints have been reached, the setpoints of the next level are applied.
For this, heating the DHW cylinder still takes priority.
Buffer storage tank: During any heating with solar energy, the buffer
storage tank is charged first at any level (A, B or C). Other consumers
with the same level will only be charged afterwards. Once all setpoints
have been reached, the setpoints of the next level are applied. For this,
charging the buffer cylinder still takes priority.

(1) With swimming pool heating set as priority (prog. no. 2065), the swimming
pool will be heated before the storage tanks.

Charging priority solar (2065), page 93
Charging time relative prio (3825)
If the preferred storage tank corresponding to the charging control not be
charged, during the time set here the priority goes to the next storage tank
or the swimming pool.
Waiting time relative prio (3826)
Transfer of priority is delayed by the time selected here.
Waiting time parallel op (3827)
Parallel operation is feasible when using solar primary pumps subject to
there being sufficient solar energy available. For this, in addition to the
storage tank currently being heated, the next storage tank in the priority
order can also be heated in parallel. The storage tank switching on for par­
allel operation can be delayed and stepped by the value set here.
Delay secondary pump (3828)
Operation of the secondary pump of the heat exchanger/indirect coil can
be delayed to enable any cold water that may be present to be flushed
through the primary circuit first by the pump.
Collector start function (3830)
If the temperature at the collector with the pump turned off is not meas­
ured correctly (e.g. with vacuum tubes), then a periodic switching on of the
pump is possible.
