If the ventilation unit detects that the filter needs to be cleaned or
replaced, the unit sends a message to the controllable
CO2 sensor
,
and RH sensor (if connected). The status LED on the sensor then
flashes orange at 1 Hz. After cleaning or changing the filter, reset
the counter, see Resetting the Dirty Filter Indication on page 30.
2.8.4.3. Filter warning Spider

show the message Replace filter. The orange filter symbol flashes
and the ventilation symbol and the Service button illuminate
continuously. After cleaning or changing the filter, the counter must
be reset, see Resetting the dirt filter indicator on page 30.

2.8.5. Ventilation Coupling VKK
With the coupling type VKK and VKK-HB it is possible to
connect the HRU ECO 350 to the Remeha HR combi boiler the
Avanta. The purpose of the coupler is to simplify the ducting
system between the HRU ECO 350 and the boiler. Both the
ventilation installation and the boiler need a supply and an
exhaust duct to and from the outside. The VKK coupler
combines the outlet of the ventilation installation with the supply
and outlet of the boiler (2 duct system).
For example, only a supply and exhaust duct is required
for the ventilation system (up to 12 floors).
The coupling type VKK-HB (up to 40 storeys) combines the air
outlet of the ventilation system with the air supply of the boiler. Both
have a separate exhaust system (3-channel system).

the ventilation unit!
