Function description
DHW heating with solar energy
Solar circuit pump R1 eE starts and
DHW cylinder qP is heated up if the tem-
perature differential between collector
temperature sensor S1 eQ and cylinder
temperature sensor S2 qQ exceeds the
start temperature differential ΔT.
Solar circuit pump R1 eE is stopped in
accordance with the following criteria:
