11.2.1.Temperature Alarms
Outdoor T° Compensation on Temp. Alarms
The following diagrams explain how temperature alarms are detected:
When the average room temperature exceeds
the high temperature alarm setting (Set Point
+ Hi Offset), a high temperature alarm sets
off. When the average room temperature
decreases below the low temperature alarm
limit (Set Point - Lo Offset), a low temperature
alarm sets off.
The critical temperature is the absolute maximum allowable temperature in the room.
Outside Temperature Influence on Alarms:
This feature avoids false alarms due to warm
weather: the room temperature 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°+ Outside Influence or lower
than the Set Point + Hi Offset, whichever is
higher but in every case, it must remain below
the critical temperature, no matter what the
outside temperature is.

2.Set the following parameters:
Low High Temperature Offset — The Hi and
low offsets are the number of degrees below
and above the set point at which a temperature alarm sets off. The low temperature limit
ranges from 20°F to 0.5°F (11.1 to 0.3°C)
below the set point (Lo Offset). The high temperature limit ranges from 0.5°F to 35°F (0.3
to 19.4°C) above the set point (Hi Offset).
Outside Influence — The outside temperature
influence is the number of degrees that are
added to the outside temperature to avoid
false alarms on warm days. Refer to the
previous diagram.
Critical Temperature — The critical temperature is the absolute maximum temperature
that is allowed in the room.
High Breaker Alarm — If the temperature of
the main breaker is monitored by a probe, set
the probe temperature over which a breaker
temperature alarm must sound. *Accessible
if the breaker’s monitoring function is enabled in
section 4.5.
Install the breaker’s probe close to the
breaker box, not inside the box!
