Initial calibration
After the installation the unit need to be calibrated to adapt any specific duct system. This is
done by connecting a computer with MS Windows, to the USB hidden under a black rubber
ceiling, on the front cover, and start up the PC Tool software, specific for this unit type..
The unit is fitted with a 230V Schuko plug. NEVER cut away this plug. The unit needs to have
an easy disconnecting possibility., as it needs to be rebooted when doing a firmware up-
grade, as well as being disconnected when connecting additional connections.
Connect the plug into an 230V socket with earth.
Locate the black rubber bushing, and remove it, to be able to connect the enclosed USB
cable, between the unit and your computer.
Please follow this procedure to calibrate the unit:

Locate the air flow chart placed on
the front cover of the HCC 260/360.
Based on the required air volume
for each specific installation, its
possible to read out the corre-
sponding pressure drop over the
heat exchanger.
