▪
Switch number: 5

Position number: 07
Other functions
Like in a 1-group linked-control system, other VAM functions can also be
configured.
Central control system
To change the settings, P1/P2 of the controller MUST be connected to the heat
reclaim ventilation units. The controller can be removed after the settings are
changed.
If the unit is supposed to operate without controller, do NOT switch it on with the
controller connected. Otherwise, the unit will give an error once the controller is
removed, because it will keep on searching for the controller signal. To resolve the
error, perform a power reset without the controller connected.
