SYSTEM DIAGRAM
VVM 500 consists of a hot water coil, immersion heater,
circulation pumps, buffer vessel, control system and is
prepared for use with solar panels. VVM 500 connects
to the climate system.
VVM 500 is directly adapted for connection and commu-
nication with a compatible NIBE air/water heat pump,
see section "Outdoor modules", and together they con-
stitute a complete heating installation.
When it is cold outdoors, the air/water heat pump works
with VVM 500, and if the outdoor air temperature falls
below the heat pump’s stop temperature, all heating is
carried out by VVM 500.
