7.1. SYSTEM NOTIFICATIONS

The system notifies the user about the failures by warnings that are cancelled automatically and by alarms that have to be cancelled manually. It
is recommended that the alarms are cancelled by a specialist prior to detection of the causes of the alarm. Information about alarms/warnings is
displayed on a particular unit's control environment's main window. The alarms can be cancelled in the same control environment. If at least one
alarm is active, the system is shut down and an external failure indication is activated.
More information about controller notifications can be found in the Air Handling unit's controller (MCB) manual, section "DIS-
PLAY AND CANCELLATION OF ALARMS AND WARNINGS". Follow the link on the last page of this document.
