6.5. Cooling Outputs
The controller has six cooling outputs that can
be used to operate cooling devices such as mist
units. The intensity of these outputs increases
gradually as the house temperature increases.
The following diagram illustrates the cooling
outputs’ operation.

The cooling output starts operating accord-
ing to a timer (On Time & Off Time) when its
start temperature is reached. The output’s
timer gradually changes as the temperature
increases. It reaches the max timer settings
(Max On Time & Max Off Time) when the
house temperature reaches the

Temperature
. Start and stop temperatures of
cooling outputs are related to the house set
point. This means that when the house set
point changes, start and stop temperatures
are adjusted consequently.
It is also possible to define a time range over
which cooling outputs can run. This time
range allows deactivating cooling outputs at
night for instance.
Reference temperature
In sidewall ventilation, cooling outputs oper-
ate according to the average house tempera-
ture; in tunnel ventilation, they operate ac-
cording to the average temperature measured
by user-defined probes. Refer to section 4.5.3
to assign these probes.

2. Set the following parameters:
House Set Point —
Current reading of the house
set point. This reading is shown as a reference
only, it cannot be modified from here.
Display —
Select the desired cooling output.
All following parameters are related to the
chosen output.
Off Temperature —
Set the temperature
below which the cooling output stops oper-
ating. Adjustable from -40 to 120°F (-40 to
48.9°C) and must be lower than the output’s
start temperature.
On Temperature —
Set the temperature at
which the cooling output starts operating
using the regular timer. Adjustable from -40
to 120°F (-40 to 48.9°C) and must be greater
than the House Set Point.
Maximum Run at —
Set the temperature at
which the cooling output starts using the
maximum timer. Adjustable from -40 to
