brooder heater is on.
Allow purge? — By default, the controller
automatically disables the curtain purge
when using the interlock function. Select
"Yes" if you purge cycles to continue within
that mode.
Use Cooling? — The controller can control
one cooling output. Select "Yes" to enable
this output.
Use Stir Fan? — The controller can control
one stir fan output. Select "Yes" to enable
this output.
Use Soaking? — The controller can control
one soaking output. Select "Yes" to enable
this output.
Variable-Speed Fan Minimum Speed — Set
the absolute minimum fan speed of each
variable fan outputs (this speed does not
apply to the minimum ventilation cycles and
to stage 1). *This parameter is accessible if the
variable outputs are enabled above.
Motor Curve — The relationship between the
voltage supplied to a motor and its operating
speed is described by a motor curve. This
curve varies with the make and capacity of
the motor. The various motors available in the
industry have been divided into ten categories
and the controller has been programmed with
a different motor curve for each of these
categories. To ensure that the controller
supplies the correct voltages, an appropri-
ate curve must be selected according to the
type of fan motors used. The table at the
back of the installation guide enclosed with
your controller gives the motor curves used
by the different type of fans. Set this curve
separately for each variable output in use.
Use Outdoor Temperature Compensation on
Variable Stages 1 and 2 ?— Select "Yes" to
use the outside temperature compensation
function to infl uence the bandwidth of vari-
able fan outputs. *This parameter is accessible
if the outside temperature sensor is enabled (see
sec. 4.7.1.)
Digit Display — Select the information to be
displayed on the red LED display:
T°
average temperature
SP
static pressure
T°/SP
avg temperature & static pressure
T°/I1
avg temperature & inlet position
SP/I1
static pressure & inlet position

RH Compensation
Setup
The controller offers different ways to com-
pensate for high and low relative humidity
(RH) levels in the barn. This section shows
how to enable the desired RH compensation
functions. Refer to chapter 9 of this manual
to get more information about each of these
compensation methods.
1. Select:
» USER
5. RH Compensation*
»
* This menu is accessible if the humidity probe is
enabled (sec. 4.7.1).
RH Compensation
Minimum Vent ?
Yes
Heater
?
Yes
Mist Shutoff ?
Yes
Curtain purge only
on Hi RH ?
No
Mist on Lo %RH? Yes
2. Enable or disable the following relative
humidity (RH) compensation options:
Minimum Ventilation — The controller can
compensate for high humidity levels by
increasing the minimum ventilation inten-
sity. Select "Yes" to use this compensation
method.
Heater — The controller can compensate for
high humidity levels by activating heating
outputs in timer mode. Select "Yes" to use
this compensation method.
Curtain Purge on Hi RH? — The curtain's
purge function can be enabled permanently
or it can exclusively be used when the RH
level is above the RH set point. Select "Yes"
to use the purge function on high RH levels
only. *Accessible if the Purge function is enabled in
the installation (see sec. 4.5). Refer to sec. 6.4.3 for
further information about this function.
Mist Shutoff — The controller can deactivate
the misting output when humidity levels are
too high. Select "Yes" to use this compensa-
tion method.
Mist on Low % RH — The controller can acti-
vate misting outputs when humidity levels are
too low. Select "Yes" to use this compensa-
tion method.

Probe Setup
4.6.1. Probe Activation
Follow these steps to enable or disable the
probe inputs of the controller.
a) Temperature Probe Inputs:
1. Select:
» USER
2. Temp Probes
»
Temp Probes Used
123456
2. Enable the desired temperature probe
inputs.
b) Other Probe Inputs:
1. Select:
» USER
3. Other Probes
»
Probe Selection
Use RH?
Yes
Use Water?
Yes
Use Outdoor?
Yes
Use Stat.Press? Yes
2. Enable the desired temperature probe
inputs amongst the probes that follow:
Use RH — Select "Yes" if a humidity probe is
connected to the controller.
Use Water ? — Select "Yes" if a water meter
is connected to the controller.
Use Outdoor? — Select "Yes" if an outside
temperature probe is connected to the con-
troller.
Static pressure (SP) probe — Select "Yes" if
a static pressure sensor is connected to the
controller.
