7.1.5 Drain-back function
If this function is active when the solar circuit pump is switched o, then the
medium drains back into a collection container. This prevents the system freezing
or overheating. When the pump is switched back on, it is operated at maximum
capacity for the preset ll time before then switching to capacity control.
Recooling is not possible at this time (menu items 3 and 4 are not shown)
