7.3. Heat Mats (0-10V)
The controller has two 0-10V outputs that
can either be used to control heat lamps, heat
mats, inlets or fans. To operate these outputs,
the controller refers to the average tempera-
ture reading of their assigned temperature
probes (see sec. 4.7.3). This section explains
how a 0-10V heat mat works.

A 0-10V heat mat starts operating at its full
intensity (100%) when the average tempera-
ture of chosen sensors reaches gets 0.5°F
(0.3°C) lower than the start temperature of
the output.
0-10V Mode: Automatic / Manual
You can manually control the intensity of a
0-10V output by using the manual control
mode. While this mode is used, the control-
ler stops controlling the output and lets you
choose the intensity of the output.

0-10V Output #X Heat Mat
Mode Automatic
Current Output 0 %
Start Temperature 70.0 °F
Set the following parameters:2.
Mode — Set the operating mode of the 0-10V
output: select “Automatic” if you want the con-
troller to control the output or select “Manual” to
specify the intensity of the output yourself.
Current output — This is the current intensity
of the output. This intensity can be modified
while the manual mode is enabled above.
Start temperature — Set the start tempera-
ture to the desired value. Note that this tem-
perature can be set as a fix value (absolute)
or it can be related to the set point: this
means that when the set point changes, the
start temperature is adjusted by the same
amount. (refer to section 4.5 to specify if
the start temperature of the 0-10V follows
the set point or not).

Set the following parameters:2.
Mode — Set the operating mode of the
0-10V output: select “Automatic” if you want
the controller to control the output or select
“Manual” to specify the intensity of the out-
put yourself.
Current output — This is the current intensity
of the output. This intensity can be modified
while the manual mode is enabled above.
Start temperature — Set the start tempera-
ture to the desired value. Note that this tem-
perature can be set as a fix value (absolute)
or it can be related to the set point: this
means that when the set point changes, the
start temperature is adjusted by the same
amount. (refer to section 4.5 to specify if
the start temperature of the 0-10V follows
the set point or not).
Minimum & max intensities — Set the mini-
mum and maximum intensities of the 0-10V
output. The maximum intensity of the output
must be greater than the minimum intensity
parameter value.
Maximum output at — This is the temperature
at which the output reaches its maximum in-
tensity. It must be set to a higher temperature
value than the start temperature.
Stop a t Day — This is the last operating day of
the heat lamp output (the day number refers
to the animal age). Set it to the desired value
or decrease the value until the letters “Off ”
are displayed to disable this function.
