3.2 Ventilator Speed
Both ventilators can be set independently of each other,
so that the airflow at the inlet and outlet are equal, which
results in optimal operation. Commissioning of the unit
must be carried out using technical equipment for and
may be done without the use of a main regulating damper.
It is not advised to set the airflow without expert help and
guidance. Incorrect settings can result in increased energy
use.
You must manually select the ventilation unit’s operating
level. You can select this with a short press of the button
B3.
Choose the ventilation speed:
Level 0 inlet/outlet airflow: LEDs off –
Standby – cannot be set via the display
Level 1 inlet/outlet airflow: LED D1 on –
Default 25% (can be changed, see below)
Level 2 inlet/outlet airflow: LED D2 on –
Default 50% (can be changed, see below)
Level 3 inlet/outlet airflow: LED D3 on –
Default 75% (can be changed, see below)
Level 4 inlet/outlet airflow: LED D4 on –
Always operated at 100% and cannot be set
By default the system is always operating. If the unit is to
be set to Standby, it can only be done via a data logger.
Alternatively, the unit can be switched off at the main
switch.
The procedure for setting the ventilator speed to level
1, 2 and 3 is described below. If no button is activated
within 100 seconds in the set-up menu, the control system
automatically returns to the main display.
Level 1 outlet airflow
Level 1 is the lowest speed. This is often used with no-one
is at home.
To access level 1 from the main display, hold down button
B3 for more than 10 seconds until LED D1 begins to flash.
Outlet airflow can now be set to level 1.
If you are already in the ventilator settings menu, just
press B4 repeatedly until LED D1 begins flashing.
Each press of B3 decreases the outlet airflow by 1%.
Each press of B5 increases the outlet airflow by 1%.
To return to the main display, press button B4 repeatedly
until all of the LED’s stop flashing.
Level 2 outlet airflow
Level 2 is the recommended operating level for an optimal
indoor climate and should be commissioned to meet the
building’s ventilation requirements.
To access level 2 from the main display, hold down button
B3 for more than 10 seconds until LED D1 begins to flash.
Press button B4 once more until LED D2 begins flashing.
Outlet airflow can now be set to level 2.
If you are already in the ventilator settings menu, just
press B4 repeatedly until LED D2 begins flashing.
Each press of B3 decreases the level 2 outlet airflow by
1%.
Each press of B5 increases the level 2 outlet airflow by
1%.
To return to the main display, press button B4 repeatedly
until all of the LED’s stop flashing.
Level 3 outlet airflow
Level 3 is the highest speed that can be set. It is typically
used when there are a lot of people, or there is a lot of
activity in the kitchen.
To access level 3 from the main display, hold down button
B3 for more than 10 seconds until LED D1 begins to flash.
Press button B4 twice more until LED D3 begins flashing.
Outlet airflow can now be set to level 3.
If you are already in the ventilator settings, just press B4
repeatedly until LED D3 begins flashing.
Each press of B3 decreases the level 3 outlet airflow by
1%.
Each press of B5 increases the level 3 outlet airflow by
1%.
To return to the main display, press button B4 repeatedly
until all of the LED’s stop flashing.
Sucking out
Level 1 inlet airflow
Level 1 inlet airflow is to be adjusted to match the level 1
outlet airflow.
To access level 1 from the main display, hold down button
B3 for more than 10 seconds until LED D1 begins to flash.
Press button B4 three times more until LED D1/D5 begin
to flash at the same time. Inlet airflow can now be set to
level 1.
If you are already in the ventilator settings menu, just
press B4 repeatedly until LED D1/D5 begin flashing at the
same time.
Each press of B3 decreases the inlet airflow by 1%.
Each press of B5 increases the inlet airflow by 1%.
