Temp diff off swi pool (3817) and Charging temp min swi pool
(3818)
The switch-on and switch-off point of the collector pump is set with these
functions. The basis for this is the temperature difference between the
collector temperature and the temperature of the buffer storage tank/
swimming pool.
In addition to the temperature difference, reaching a certain minimum
collector temperature is necessary for the buffer storage tank/swimming
pool charging process.
Important
The setting "- - -" causes program no. 3813, 3814, 3816 and 3817
to apply the values from program no. 3810 (for program no. 3813
and 3816) and program no. 3811 (for program no. 3814 and
3817). The values from program no. 3810 and 3811 are always
used for the DHW storage tank.
Charging prio storage tank (3822)
If several storage tanks are connected to the system, the charging
sequence can be determined by setting the charging process.
None: Every storage tank is charged alternately with a temperature
increase 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.
DHW storage tank: The DHW storage tank is charged as priority during
any heating with solar energy 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,
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. During
this process, the charging of the buffer storage tank again takes priority.

ed first, between the domestic water and the buffer storage tank or last.
Charging time relative prio (3825)
If the preferred storage tank cannot be charged in accordance with the
charging control (e.g. if the temperature difference between the priority
storage tank and the collector is too small), priority will be given to the next
storage tank or the swimming pool during the time set here.
Waiting time relative prio (3826)
Transfer of priority is delayed by the time selected here.
