13.2.1. Critical Temperature Ramp
The controller can automatically change the
critical temperature alarm limit over time with
a three-step ramp. Each step specifies associ-
ates a critical temperature alarm limit with an
animal age. Once the steps are defined and
the ramp is activated, the controller changes
the critical alarm limit in a linear fashion be-
tween consecutive steps of the ramp. When
the last step is reached, the controller keeps
using the alarm limit associated with it until
a new flock starts.

*The param-
eters below are common to all programs.
Critical Alarm Ramp — This is the status
of the alarm ramp. Prior to activating the
ramp, make sure the parameters below are
set properly.
Age — Set the age at which each step starts.
The age ranges from -5 to 450 days (negative
values are used to prepare the house before
letting the animals in).
Critical T° — Assign a critical temperature
alarm limit with each step of the ramp.
13.2.2. Static Pressure Alarms
The controller can set off an alarm when
the static pressure (S.P.) level exceeds the
high or low pressure alarm limit for a certain
period of time.
Note that the static pressure alarm
conditions are not monitored while the
controller is in natural ventilation.
• Low Static Pressure Alarm: When a low
pressure alarm occurs, the controller switches
on the alarm relay and the low pressure alarm
relay (the low pressure relay can be used to
activate additional fans for instance). Refer to
section 4.7 to enable this type or relay.
Low Static Pressure Alarm in Minimum •
Ventilation: In minimum ventilation, the con-
troller only monitors the low pressure alarm
condition while the fans are running (i.e.,
during the
“On Time” portion of the minimum
ventilation cycle).
High Static Pressure Alarm: • When a high
static pressure alarm occurs, the control-
ler switches on the alarm relay and opens
all air inlets (sidewall vent, attic vent and
tunnel inlets). The inlets open continuously
until the pressure level gets back in the ac-
ceptable pressure range and until the user
acknowledges the alarm by accessing the
alarm log menu.

*A password may be required to access this menu
(see section 4.2.1). In addition, this menu is only
accessible if the controller uses the sidewall and/
or tunnel ventilation modes (i.e., if at least 1 fan or
tunnel fan is enabled in the Set-up menu).
Set the following parameters: 2.
High / Low S.P. — Set the pressure levels
below and above which an alarm is declared.
*
These parameters are accessible if a static pres-
sure sensor is enabled in the Set-up menu (see
section 4.4).
S.P. Delay — The high or low pressure condi-
tion must be maintained all along this period
of time for the controller to set off the alarm.
Set the static pressure alarm delay to the
desired value. *
This parameter is accessible if a
static pressure sensor is enabled in the Set-up menu
(see section 4.4).
Low Tun — Set the pressure level below
which a low pressure alarm must set off when
the controller is in tunnel ventilation. *
This pa-
rameter is accessible if a pressure-based tunnel inlet
is enabled in the Set-up menu (see section 4.4).
