4.1.3 CPs Mode : setup, operating instructions and wiring diagrams
4.1.3.1 Setup CPs mode
The setup is made by means of the LCD screen and the 4 knobs SETUP,
the RC. To start the setup:
- Enter in the setup mode using the left knob on the diagram so that the SETUP LED ignites
- Press then the SETUP knob until the text 'SETUP' appears on the screen.
The idea is to select your choice with the
pressing 'ENTER'. The numbers are introduced digit by digit.

SETUP
Note that the CPs mode can be either active on the supply or the exhaust side of the unit (see 3, in table above):
CPs on SUPPLY air: The airflow delivered by the supply fan is automatically modulated to obtain a constant
pressure as measured by the pressure sensor in the duct. The exhaust airflow is equals to %EXT/PUL of the supply
airflow.
CPs on EXHAUST air: The airflow delivered by the exhaust fan is automatically modulated to obtain a constant
pressure as measured by the pressure sensor in the duct. The supply airflow is equals to 1/(%EXT/PUL) of the
exhaust airflow.
