SYSTEM DIAGRAM
VVM 310 consists of hot water coil for hot water heating,
immersion heater, circulation pumps, buffer vessel and
control system. VVM 310 connects to the climate system.
VVM 310 is directly adapted for connection and communic-
ation with a compatible NIBE air/water heat pump, see sec-
tion "Outdoor modules", and together they constitute a
complete heating installation.
When it is cold outdoors, the air/water heat pump works
with VVM 310, and if the outdoor air temperature falls below
the heat pump’s stop temperature, all heating is carried out
by VVM 310.
