IOM TERMINAL BOARD

Installationmanual Terminal Board
The terminal board enables the connection of a cable remote control, a BMS gateway or the
connection to an external on / off contact.
Make sure that the cable that goes to the terminal board (Fig. 2) comes from the correct port on the
mutifunctional board (Fig.1) for your application.
SWITCH1 / SWITCH2 (without jumper): When the external contact is closed, the
indoor unit stops operating. The indoor unit cannot then be switched on with a
remote control. If the external contact is opened again, the indoor unit starts with the
settings that were last made on the remote control.
ON / OFF1 / ON / OFF2: When the external contact is closed, the indoor unit stops
operating. If the contact is opened again, the indoor unit starts in fan mode. The
remote control is also active when the contact is closed, i.e. the indoor unit can be
started despite the contact being closed.
