hot water accessories in different systems together
with NIBE heat pumps. This also requires a hot water
accumulator, for example, NIBE VPB or VPA.

FUNCTION
When there is hot water demand the charge flow is
guided to the hot water accumulator using the reversing
valve (QN10). In other cases the charge flow is con-
trolled through the remaining parts of the system, for
example the heating system.
