Fancom I-FAN COMPLETE Bedienungsanleitung Seite 18

Do not touch any of the I-fan moving parts.
Fancom advises to leave the I-fan on for about 6 hours after installation, to let it run in.
Analogue control (0-10V;10-0V)
Digital control (I/O network) If the I-fan is controlled via the I/O network, this can be
bridged with a manual control via the -10V input. In this
case, both the I/O network and the 0-10V are connected.
A manual control has the following positions:

AUT : (0-1V) automatic regulation via the I/O network

OFF : (1-1.5V)

MAN : (1.5-10V) manual regulation (continuous) via
manual control
