ALARM SETTINGS
The alarm output is activated when certain alarm conditions are detected.
For example, when the room temperature is too high or too low, an alarm
is set off. Each new alarm type is recorded in memory until it is acknowl-
edged by the user. If the alarm condition is still valid, the alarm is kept in
memory. Otherwise, it is erased from alarm memory. The alarm condi-
tions are as follows:
Out sensor fail
Unacknowledged
When an alarm is ACTIVE, the alarm
condition is still valid. The alarm remains
in alarm memory even if the user ac-
knowledges it. When an alarm is UN-
ACKNOWLEDGED, it is kept in memory until it has been acknowledged by
the user. Once this is done, it is erased from alarm memory. If an alarm is
ACKNOWLEDGED, it has been acknowledged by the user but is still active.
Note that in the case of an active alarm, the alarm output remains
activated even if the alarm is acknowledged.
