RUNTIME
CIRC.PUL-

If operation of the circulation is
pulse-controlled, the runtime of

this value. This minimum runtime
is also applicable in relation to tap
support.

CIRC. MODE
WHEN TAPPED
Circulation

tapping. This determines whether
the selected circulation mode is
active during tapping or not. Note:
Tap support is always active irre-
spective of this definition.
