CONTROLS
The control functions for the P control system
software are described below:
P  CONTROL SYSTEM
Energy meter
Monitoring of energy
consumption for each
unit, using a built-in
energy meter with
display.

control panel
Sensors
• On-demand air volume linked to CO
2
level, using a
CO
2
sensor.
• Integrated 12 Volt power supply to multiple
sensors.
• Integrated 24 Volt power supply to single sensor.
• 3 analogue and 3 digital inputs for sensors.
- Analogue inputs can also be used as digital
inputs.
- Inputs can be programmed as required. A
ventilation unit can thus be fully automatically
controlled using multiple dynamic and contact
sensors.
Night time cooling
Independent, automatic
night time cooling. The pro-
gram can be adapted to suit
customer requirements.
Analogue CTS
Control via analogue
CTS possible, which
controls operating
hours and air volume or
inlet temperature.
Heating surfaces
• Automatic control of pre- and
comfort heating surfaces.
• Frost protection using "Virtual
preheat" and comfort heating
surface or "Preheat" with a pre-
heating surface.
No draughts or cold air
discomfort
• Automatic bypass control to
maintain inlet temperature.
• Control of motorised
damper.
External Emergency Stop
Deactivation of the unit from an external signal inde-
pendent 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 exhaust dampers.
Startup guide
An integrated startup guide ensures
easy, quick programming during instal-
lation of the ventilation unit. The guide
is integrated in the setup menu, and can
be restarted at any time.
Timer control
• All timer controls are in the same menu
and can run in parallel. This provides an
overview of timed ventilation and night
time cooling, plus easy, flexible adjust-
ment of time 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.
Monitoring
• The control system constantly monitors air
volume, to ensure that the unit can always
provide balanced ventilation regardless of
counter-pressure.
• Filter monitoring using an hour counter and
electronic flow monitoring. Time intervals
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.
• Alarm output for remote monitoring of
ventilation unit.
Data logging
• Continuous data log of all major operating
data.
• A data log can be converted to a predefined
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 overwrit-
ten 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 sensor
connected.
- Reading energy consumption for each
unit.
Control box
• Integrated cooling module control.
• 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.
