Circl-Pump Interval
Setting of the interval control for an optional circulation pump.
Off: Deactivated. The circulation pump runs permanently during the release times of the as-
signed switching time program ([Circl-Pump DHW] parameter).
Otherwise: The circulation pump runs clocked (clock cycle ratio: pump runtime = setting value
each 15 min).
