Is the maximal area depended flow correctly adjusted?
First, the controller has to be set into the manual operation mode (100% pump output). Then the desired maximal area depended flow has to be adjusted. Rule of thumb for the area depended flow: Collector system for the preparation of warm water: 40l/h x m² absorber area = area depended flow Through reduction of the area depended flow the desired temperature enhancement of the heat transfer medium can be achieved.
