Function
2. Storage operation
When requesting space heating and domestic water heating (storage) at the same time, this involves
that the storage function is active and the start timer is reached (setting 1) during space heating
operation. The 3-way valve will switch over to domestic water heating operation. Now domestic
water will be produced till set point is reached or according to the running timer (setting [d-01]). The
3-way valve will switch back to space heating mode for the interval period (setting [d-02]). After this
interval the 3-way valve will go back to domestic water mode. This will continue till set point is
reached. At that moment, simultaneous request is finished and the system goes back to space heating
mode.
During the storage operation, the system does not take care off the room temperature. This means that
during simultaneous demand, the space only will be heated during the intervals of domestic water
production.
