5.13.2 Setting Alarm Limits
The following diagram explains how temperature alarms are detected:
When the average room temperature exceeds the high temperature
alarm setting (Set Point + Hi Offset), a high temperature alarm is
generated. When the average room temperature drops below the low
temperature alarm setting (Set Point - Lo Offset), a low temperature
alarm is generated.
The critical temperature is the absolute maximum temperature allowed
in the room.
Oustide Temperature Influence on Alarms:
This feature avoids false alarms due to warm weather: the room tem-
perature can exceed the Hi temperature limit in the case where the
outside temperature is warm enough. The room temperature must
remain equal or lower than: Outside T°+ Hi Offset+ Outside Influence.
The room temperature must always remain below the critical tempera-
ture, no matter what the outside temperature is. The following diagram
illustrates this situation:
