The external switch digital input can be used to stop the unit remotely. If the external switch input is triggered the unit will initiate the stop sequence
and stop the ventilation. A controller alarm will also appear on the unit external display to indicate that the external switch is active.

A means of triggering the input will be required (field supplied and specified) and wired to TB3 76 & 4, DI6 & +24VDC respectively (see
wiring diagram). Remember to cut the power to the unit at the all pole circuit breaker before performing any electrical work.
The external switch input is configured on DI6 from the factory and is set as a normally open contact (NO) by default. If you require a normally closed
contact (NC) follow the steps below.

Alarm handling
The unit controller comes with preprogrammed alarms to ensure it functions properly and to help troubleshoot problems when they occur. Active
alarms are indicated by the flashing red LED on the unit external display.
These alarms have different characteristics. Alarms related to safe operation of the unit (alarms class A and B) will, when triggered, stop the
ventilation until the alarm has been acknowledged and the alarm conditions are no longer met. Alarms of lower priority (Classe C) will not stop the
ventilation and will auto reset once the alarm conditions are no longer met. Each alarm has a delay which is the time period the alarm conditions have
to be met before the alarm is triggered. The table below lists all the preconfigured alarms of the unit with their descriptions and other characteristics.
See table below.
