7. HEATING
Heating Stages
7.1.
The controller can control up to 6 indepen-
dent heating outputs. Each heating output
operates according to its start and stop
temperature. Refer to section 4.5 to enable
heating outputs.
Reference Temperature:
Start/stop tempera-
tures are related to the set point. This means
that they are automatically adjusted when the
set point changes.
Heaters 1-3:
The controller has 3 basic heat-
ing outputs.
Heaters’ Hi Fire:
In addition to its 3 basic
heating outputs, the controller can simulate
additional heating outputs with the Hi Fire op-
tion. When this option is used, the controller
doubles the number of heating outputs in use.
Each simulated heating output (Hi Fire Step)
operates as a regular heating output, with its
own start/stop temperatures, relay selection
and probe selection. Refer to section 4.5 to
activate the heaters’ Hi fire option.

Set the following parameters:
2.
On temperature —
Set the temperature below
which each heating stage starts. If the Hi/Lo
fire option is used, set this temperature sepa-
rately for both steps of the heating stage. In
addition, if the night heater offset is enabled
in section 4.8.4, these parameters must be
set separately for day & night.
Off temperature —
Set the temperature at
which each heating stage stops. Note that
the Off Temperature of an heating stage
must be at least 0.5°F (0.3°C) higher that
its On Temperature. If the Hi/Lo fire option is
used, set this temperature separately for both
steps of the heating stage. In addition, if the
night heater offset is enabled in section 4.8.4,
these parameters must be set separately for
day & night.
7.2. Heat Lamps (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 0-10V heat lamps work.

0-10V heat lamps start at their minimum inten-
sity when the temperature falls below the start
temperature of the output. The intensity of heat
lamps increases as the temperature decreases;
the maximum intensity is reached when the
temperature falls below the Max. Temperature
parameter setting.
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.
