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

Every storage tank is charged alternately for a temperature increase of 5 °C at a time,

until every setpoint of level A, B or C (see below) is reached. The setpoints of the next

higher level are approached only when 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 setpoints of a level are attained, those of the

next level are approached, whereby priority is again given to the DHW storage tank.

Buffer sensor

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 setpoints of a level are attained, those of the

next level are approached, whereby priority is again given to the buffer storage tank.

When priority for the swimming pool is activated (2065), the swimming pool is

charged before the storage tanks.

If the preferred storage tank cannot be charged in accordance with charging control,

priority is transferred to the next storage tank or the swimming pool for the period of

time set (e.g. temperature differential between collector and storage tank too great).

As soon as the preferred storage tank (according to setting "Charging prio storage

tank") is again ready to be charged, the transfer of priority will immediately be stopped.
