control unit. In this phase, the rated current of each ventilation line
is read and stored, a significant increase in absorption compared to
this value will intervene will cause the fault relay to intervene and
deactivate the line.
It is possible to perform the auto tuning when you want, but it
must be done at least once when first turned on after installation.
In the absence of this operation, the control unit will work with the
standard absorption values and will no longer be guaranteed correct
sensitivity of the overload protection.
Pressing the centre key switches between manual and automatic
operation. In automatic mode the ventilation consent switches to be
under the control of a remote unit that usually controls the ventilation
by means of PT100 sensors (MT200 Lite ME100). In manual mode,
it is possible to act locally to activate or deactivate the ventilation
lines.
The control unit, without power, maintains the operation state and
upon the next restart, restores the previous state.
Note: in case of intervention of the control unit, it is necessary to re-
perform the auto-tuning in order to cancel the alarm state
