Connecting solar panel cooling if any
To prevent the glycol mixture in the solar panel from
boiling while strong sunshine and VVM 310 is fully
charged it is possible to connect a cooling function for
the solar panel in accessory card (AA5). Cooling is
generated using a relay and occurs for example by
flushing out hot water or rerouting the solar circuit to
a convector fan.
Connect the relay for solar panel cooling to AA5-X9:3
(N) and AA5-X9:4 (230 V) in the unit box (AA25).
