Data logging
• Continuous data log of all major operating
data.
• A data log can be converted to a predefi-
ned period log.
• Log frequency and operating data can be
adapted.
• The control system is set as default to log
data every 5 minutes - the memory is big
enough to collect data for 1 year. When
the memory is full, the oldest data is over-
written to ensure access to the newest
data. The advantages are:
- Production of very accurate operating
data, which can be used for identifying
errors for example.
- Generation of operating reports for
each unit.
- Documentation of air quality using a
CO
2
sensor or electronic humidity sen-
sor connected.
Sensors
• On-demand air volume according to air humi-
dity via electronic humidity sensors for outdoor
and exhaust air, to ensure optimal air humidity
indoors.
• On-demand air volume linked to CO
2
level, using
a CO
2
sensor.
• Integrated 13.5 Volt power supply to sensors.
• 2 analogue inputs for external control signals:
- Inputs can also be used as digital inputs.
- Inputs can be programmed as required. The
ventilation unit can thus be fully-automatically
controlled using 2 dynamic sensors, 2 contact
sensors or 1 dynamic and 1 contact sensor.
Timer control
Timed ventilation using 7 timer programs
and built-in timer. Each timer program can
be individually programmed with air volume,
inlet temperature, days and times.
Night time cooling
Independent, automatic night time cooling.
The program can be adapted to suit.
Analogue CTS
Control via analogue CTS pos-
sible, which controls operating
hours and air volume or inlet
temperature.
Heating surfaces
• Automatic control of heating surface.
• Electronic frost protection using a
pre- or comfort heating surface and
the "Preheat" and "Virtual preheat"
functions.
Monitoring
• Filter monitoring using an hour counter.
Time interval can be adjusted.
• Condenser monitoring using a float contact.
• Electronic monitoring of sensors and venti-
lators.
• Advanced warning and alarm system.
Breakdowns can thus be quickly detected,
and ventilation becomes more reliable.
No draughts or cold air discomfort
• Automatic bypass control to maintain
inlet temperature.
• Control of motorised damper.
Control box
• The cooling module can be controlled via
a supplementary PCB.
• Network connection via a supplementary
PCB to KNX
®
, LON
®
, MODBUS
®
, BACnet
TM
MS/TP and BACnet
TM
/IP is possible.
• All control system intelligence is housed
in the control box. This allows ventilation
unit operation without a control panel.
• The control panel is connected to a sepa-
rate jack.
The control functions for the L control
system software are described below:

Energy meter
Monitoring of energy
consumption for each
unit, using a built-in
energy meter with
display.
External Emergency Stop
Deactivation of the unit from an external signal
independent of the unit's operating status and
other start signals, e.g. in an emergency.
The unit will stop the ventilators immediately,
and close the inlet and extraction dampers.
