Operation
The input of the connected sensor or switch
is translated to a neutral 0-100% signal. This
translated signal is sent to the ventilation unit as
requested airflow. The ventilation unit will compare
this request with any other incoming requests and
determine the needed airflow.
By translating the signal to a neutral 0-100%
signal a 0-600Pa 0-10V pressure sensor can be
easily replaced by for example a 0-500Pa 0.5-4.5V
pressure sensor. The input voltage settings need
to be changed only. Also, in case of control, the
setpoint needs to be adjusted.

The input voltage at 0% output and the input
voltage at 100% output is set in the Option
Box menu for each specific 0-10V input, after
enabling the input. By default, 0% output is
given at 0V input, whereas 100% output is given
at 10V. If a 0.5-4.5V pressure sensor would be
connected to steer the ventilation, the input
for 0% output would be 0.5V and the input for
100% output would be 4.5V.
11 Regulated sub-soil heat exchang-
er valve5
The device is equipped with an
optional control for a sub-soil heat
exchanger to preheat or precool
the outdoor air. The device can
control a 230V valve from an air
through ground heat exchanger.
Installation
■ Install the permanent 230V power of a sub-
soil heat exchanger valve to connector 12 (see
the wiring diagram).
■ Install the switched 230V power of a sub-soil
heat exchanger valve to connector 6b (see the
wiring diagram).
■ Install the outdoor temperature sensor of a
sub-soil heat exchanger to connector 6a (see
the wiring diagram).
■ Install the mains power cable of the device.
Commissioning
After installation there is no need to commission
the sub-soil heat exchanger on the ventilation
unit.
