3 Product Introduction
3.1 General
The controller will control an EC fan (0-10 V) depending on an internal time schedule or according to
internal/external sensors (Temp, CO2 etc.) or Building Management System. It consists of 2 parts, a
control board (CB) and a room unit (RU). The control board will ideally be situated close to the fan while
the room unit will be situated close to the user or the designated ventilation area.
This installation manual concerns the room unit and control board manufactured by Systemair AB. It
consists of basic information and recommendations concerning the design, installation, start-up and
operation, to ensure a proper fail-free operation of the unit.
The key to proper and safe operating of the unit is to read this manual thoroughly, use the unit according to
given guidelines and follow all safety requirements.
3.1.1 Description of the room unit
The objective of the room unit is to display the
information provided by the installed sensors and
make it possible for the user to enter desired
settings. The room unit is equipped with 2 internal
sensors; Temperature and humidity sensor, which
register the temperature and humidity in the
location of the installed room unit. It is possible to
connect 2 extra sensors to the internal connection
block.
Up to 10 room units can be active simultaneously.
Note:
The installed room units can only be regulated one
by one. It is not possible to perform settings on two
or more room units simultaneously!
Fig. 1 room unit
3.1.2 Description of the control board
The purpose of the control board is to provide
the room unit with 24 V DC mains supply, to
communicate information to and from the room
unit given by the sensors connected to it, and to
provide the correct output control voltage to the fan
or separate heater/cooler based on the settings in
the room unit.

3.3 Transport and Storage
The room unit and control board should be stored and transported in such a way that it is protected against
physical damage that can harm the product. The appliance is delivered complete in a cardboard box.

4 Installation
4.1 Unpacking
Verify that all ordered equipment are delivered before starting the installation. Any discrepancies from the
ordered equipment must be reported to the supplier of Systemair products.

4.2 Where to Install
The room unit is meant for indoor wall mounting preferably in an area of the building which is representative
for control of temperature or humidity, since these two functions are enclosed inside the casing of the
control. If the enclosed functions are not used and the fan or heater is controlled by sensors connected to
the central board, the physical location of the room unit inside the building is of less importance. Allowed
maximum and minimum operating temperatures are from 0°C to +50°C.
The control board is normally mounted somewhere close to the location of the fan or heater it is supposed
to control and can also be installed outdoors if necessary. Allowed maximum and minimum operating
temperatures are from –20°C to +50°C.

4.3 Installing the room unit and control board
4.3.1 Installation of the room unit
1
Find an appropriate place to install the room unit. Maximum length between room unit and control board
is 30 m. The enclosed 4 pole signal cable has a length of 10 m.
2
If needed, drill two holes in the wall (centre to
centre: 60 mm). Fasten the room unit to the wall
with 2 screws.
4.3.2 Installation of the control board
1
Find an appropriate place on the wall to install the control board, preferably close to the location of
the fan unit.
2
If needed, drill 4 holes to fasten the control board
(centre to centre: 164 mm) to the wall.
Note:
It’s recommended to mount the control board with
the enclosed transformer (pos.1) down side.
3
Connect sensors and the fan control (0–10 V DC) signal cables (figure 7).

4
Connect the enclosed 4 pole signal/power cable to
the modular jack on the print card.
The maximum length of the cable is 30 m.
Enclosed cable has a length of 10 m .
The cable is connected to the external plug on the
room unit.
If the connection plug on the room unit is not used
it is possible to connect the 4 pole signal/power
cable directly to a terminal in the room unit (pos.
4–7, figure 6). More information concerning the
wiring (figure 8 , table 2).

6 System layout
The EC Vent control system can have up to 5 active sensors (analogue), i.e. temperature, humidity, CO2,
pressure and airflow and up to 10 room units connected simultaneously. If a fan is regulated by e.g. 2
temp. sensors at the same time the highest signal controls the fan speed. Temperature sensors need to
be of the type PT1000.
Separate regulation of heating and cooling with possibility for maximum and minimum temperature
limitation in when using room sensor.
3 Digital inputs for e.g. forcing fan speed, changing set point, stop, extended running etc.
For more information about the possible operation options see “User Manual”
