The priority circuit for the swimming pool (2065) can impact the storage tank
priority of solar charging and possibly charge the swimming pool before charging
the storage tanks.
If a plant uses several heat exchangers, it is possible to set a priority for the
integrated storage tanks, which defines the charging sequence.
None
Each storage tank is alternately charged for a temperature increase of 5 °C, until
each setpoint at a level A, B or C (see below) is reached. The setpoints of the next
higher level are approached only after all setpoints of the previous level have been
reached.
DHW storage tank
During solar charging, preference is given to the DHW storage tank. At every level
A, B or C (see below), it is charged with priority. Only then will the other consumers
of the same level be charged. As soon as all set points of a level are attained,
those of the next level are approached, whereby priority is again given to the DHW
storage tank.
Buffer storage tank
During solar charging, preference is given to the buffer storage tank. At every level
A, B or C (see below), it is charged with priority. Only then will the other consumers
of the same level be charged. As soon as all set points of a level are attained,
those of the next level are approached, whereby priority is again given to the buffer
storage tank.
