8.3. Brooder
Heater
The controller can use a relay or it can use
its second 0-10V output to control a brooder
heater. Refer to the installation options in
section 3 to enable the proper type of brooder
output (relay or 0-10V).
Operating Temperature:
To operate the brooder heater, the control-
ler refers to the average reading of the
temperature probes assigned to the output
(see sec. 4.6.3). In addition, the operating
temperatures of the brooder heater can ei-
ther be de
fi
ned as absolute values or they
can be related to the set point, which means
they are automatically adjusted when the set
point changes. Refer to the installation menu
in section 3 to determine if the operating
temperatures must follow the temperature
set point or not.
Brooder’s Hi Fire:
With the Brooder Hi Fire
option, the controller controls the brooder
output in two different ways, just as if there
were two brooder outputs (regular output
and Hi-Fire output). The regular brooder
output and the Hi-Fire output each uses its
particular relay assignement and Start/Stop
temperatures. Refer to section 3 to activate
the brooder’s Hi
fi
re option.
Closing the Curtains when Brooder Heater
is ON:
The controller can automatically close the
natural ventilation curtains when the brooder
heater is on. Enable the
"Interlock"
option in
section 3 to activate this function.
Brooder Heater Curve:
The controller can adjust the start tempera-
ture of the brooder over time with a curve.
Refer to section 8.3.3 for further information
on the brooder curve.
8.3.1. On/Off Brooder Heater
The on/off brooder heater turns on when the
temperature of its probe(s) falls to the Start
Temperature; it turns off when temperature
increases and reaches the Stop Temperature.

Set the temperature
below which the brooder starts. If the Hi

option is used, set this temperature separately
for the regular and Hi Fire brooder steps. *
This
parameter cannot be modi

Stop temperature —
Set the temperature at
which the brooder stops. If the Hi

is used, set this temperature separately for
the regular and Hi Fire brooder steps.
8.3.2. 0-10V Brooder Heater
The 0-10V brooder heater starts heating
at minimum intensity when the average
temperature of its probes falls to the Start
Temperature. It then increases in intensity
as the temperature decreases and reaches its
maximum heat intensity when the tempera-
ture gets lower than the Start Temperature
— Differential. The brooder heater
fi
nally
turns off when the temperature increases and
reaches the Stop Temperature of the output.

6.2.3. 0-10V Ventilation Outputs
The controller has two 0-10V outputs that can
either be used to control heaters or fans. To
operate these outputs, the controller refers
to the average temperature reading of their
assigned temperature probes (sec. 4.7.3).
This section explains how 0-10V ventilation
outputs work.
The 0-10V ventilation outputs start at their
minimum intensity when the average tem-
perature of their probes reaches the start
temperature. They increase in intensity as
the temperature increases; 0-10V outputs
reach their maximum intensity when the tem-
perature rises to the
“Maximum Temperature”
parameter setting.

2. Set the following parameters:
Start temperature —
Set the start tempera-
ture to the desired value.
Minimum & max speeds —
Set the minimum
and maximum speeds of the 0-10V output.
The maximum speed must be greater than
the minimum speed.
Maximum output at —
Set the temperature at
which the output reaches its maximum speed
(this parameter must be set to a greater value
than the start temperature).
Stop at —
This is the temperature below
which the 0-10V output stops.
