4.8.2.2. Empty Zone Tempera-
ture Alarms
An alarm can be set off if the house tem-
perature is too low while the controller is in
clean mode. Refer to section 4.9 for further
information about the clean mode. The low
temperature alarm limit is relative to the
empty zone’s set point, which means that the
alarm limit is adjusted consequently when a
change in the empty zone set point occurs.
4.8.2.3. Water Spill Alarm
A water spill alarm is set off when the water
consumption is too high. This limit can be
adjusted from 0 to 10,000 gallons or liters
per 15 minutes and must be set separately
for both water meters.
The controller can automatically adjust the wa-
ter spill limit of each water meter over time as
the animals are growing. The water spill alarm
limit changes in a linear fashion between two
user-defined values: the maximum consump-
tion that is allowed at the beginning of the
flock (day -5) and at the end of the flock. The
following graph sums up the situation.

Static pressure Alarms
The controller can activate an alarm when the
static pressure level decreases below the low
pressure limit or if it exceeds the high pres-
sure limit. However, the alarm condition must
be maintained over a certain delay before the
alarm sets off.
• Lo static pressure alarm:
When a low pres-
sure alarm occurs, the alarm relay and the low
pressure alarm relay switch. The low pressure
relay can be used to activate additional fans
for instance Refer to section 4.7 to assign
that type of relay.
Low Static Pressure Alarm in Minimum Venti-
lation:
In minimum ventilation, a low pressure
alarm sets off if a low pressure condition is
maintained over the alarm detection delay
while fans are running. The alarm condition
time accumulates during the fans’ On Time
only and is not taken into account while fans
are not running (Off Time).
• HI Static Pressure Alarm:
When a high
static pressure alarm occurs, the alarm relay
switches and the air inlets (curtain & vent
doors) start opening continuously until the
pressure level goes back in the normal pres-
sure range.
