> Operation alternative heating circuit pump G1
B Select if circulation pump G1 should run continuously
or in optimised operation. The setting applies to G1 of
all circuits.
Continuous means that G1 is always in operation
during the heating season.
Automatic means that the circulation pump runs in
approx. 10 min, stands idle for 10 min, and so on, if it
is in winter operation and there has not been any
heating demand for 40 min. Automatic operation is
