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 defi 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.

2. Set the following parameters:
Start temperature — Set the temperature
below which the brooder starts. If the Hi fi re
option is used, set this temperature separately
for the regular and Hi Fire brooder steps. *This
parameter cannot be modifi ed if the brooder curve is
on. See to section 8.3.3 to turn off this curve.
Stop temperature — Set the temperature at
which the brooder stops. If the Hi fi re option
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.
