• It is recommended that the duct system is attached with flexible connections in order to isolate any
structure-borne noise.
• Make sure that the duct system cannot be closed.
• Make sure that the intake duct has direct access to the intake air.
• Warning: branches in the intake duct, to other fan units for example, may, if the dimensions are too
small, lead to low pressure in the duct and therefore malfunction of the unit.
• The pressure loss in the duct system must not be more than the capacity of the unit! The pressure
loss in the duct should not be more than 2/3 the unit‘s maximum pressure so that an adequate air
output can still be achieved. This will prevent malfunction.
• Pressure losses in the duct system are adversely affected by: the length of the duct system, small
pipe or duct cross-section, elbows, additional filters, valves, etc.

7.1. Overcurrent protection
• The unit may only be operated with the correct overcurrent protection.
• This must be established by a qualified electrician.
• The recommended protection is shown in the enclosed wiring diagram.
The extra-low voltage control cables must be laid separately from the mains cables.
Fig. 8:
Connections to the FFH unit.
Fig. 7:
Connection chamber (1) and cable inlets (2)
Connection compartment / Connections on the unit
The connection compartment is located in a separate connection box outside the device. The cover
of the connection box can be opened by loosening the 4 screws (see Fig. 7). Cables that carry mains
voltage must be fastened with the tension relief devices available. Connection is as described in
Section 7.2.
Unit supply cable
Connect the mains supply cable as shown in the wiring diagram.
Suitable fuse protection should be provided.
External extraction fan
A multi-stage extract air fan can be connected to the terminal block. Terminals for the corresponding
fan stage are shown in the wiring diagram. Terminals for neutral conductor and earth conductor are
also shown in the wiring diagram. (230 VAC, max, 2A)
Valve actuator
An actuator can be connected for an air damper. Terminal assignment for opening and closing the
air dampers and connecting the neutral conductor and earth conductor (see wiring diagram). To save
energy and for electrical safety, the close signal is only active for 4 minutes after the fan has been
switched off (230 VAC, max. 1 A).
Unit malfunction
If there is a malfunction on the unit, an error message appears on the display and at the same time
switches a relay. A closing and opening signal is available (see wiring diagram). Electrical connection
of the changeover contact with U - 230 VAC and Imax = 2A.
Unit enabling
The unit can be switched on and off with an external potential-free contact (see wiring diagram). An
external voltage must never be applied to this connection. The control system would be destroyed.
Any devices that provide a potential-free contact (e.g. a time switch) can be used to control the unit.
This contact must be securely isolated from interference voltages because otherwise dangerous
conditions might occur in the event of a fault.
Control unit
The control unit is connected to the supply air unit‘s control system with a control cable. A connector
on the control cable is plugged directly into the socket on the control unit from beneath (see Fig. 10).
On the unit, the control cable is rst fed through a cable gland (see Fig. 7), placed in the cable duct
and then connected to the RJ10 socket provided in the controller board. The control cable must not
be shortened. Any excess length must be stowed outside of the housing. If the cable is too short,
extensions can be ordered from the manufacturer or supplier. Alternatively, a 4-wire data cable with
120 Ohm resistance can also be connected. This is fed through the back wall of the control unit and
connected to the spring-loaded terminals. In the unit, instead of being connected to the controller
board in the RJ10 socket, the cable is connected in the spring-loaded terminals next to it (see wiring
diagram).

The following checks should be performed in accordance with the installation and operating manual and
the regulations in force:
• Correctly sealed installation of the unit and duct system.
• Check the duct system, unit and medium lines, if present, remove any foreign bodies if necessary.
• The intake opening and inflow into the unit must be clear.
• Check all mechanical and electrical protection measures (e.g. earthing).
• Voltage, frequency and type of current must correspond with the rating plate.
• Check all electrical connections and wiring.
• Check any electrical, switching, safety and control devices connected.
• The unit may not be switched on when the housing is open.
• Measure electricity consumption at operating speed and compare with the rated current.
• Check the fan for excessive vibrations and noise generation.
• The impeller must not be rubbing against the inlet nozzle or other fittings.
Warning: When the voltage is connected the blower starts up at the middle stage for about 6 sec.

P 5 Room or supply temperature control
The room or supply air temperature controller compares the air temperature measured on the room
or supply air temperature sensor with the set-point temperature set on the control unit. In the case of
heating, a difference between the set-point and actual temperature causes the controller to increase
or reduce the heat output.
With room temperature control, any external heat source in the room will
be taken into account and compensated for by a correction to the supply
air temperature. The room temperature sensor is in the control unit.
With supply air temperature control, the external heat source is not taken
into account.

Start at low external temperatures
By switching on the appliance, it can take some time until the electric heating element reaches
operating temperature. A special start-up automation will avoid that cold air is blown into the room
during this time. If supply air temperature drops more than 2 °C below the set value, the control unit
periodically checks the correct set value by switching on the fan on level 1. The appliance switches
to the selected operation mode, if the temperature reaches a higher value as the set value minus
2 °C. The control unit also changes to normal operation mode, if 7 minutes exceed the time during
start-up automation.
Thermal contact
The motor has a thermal contact that opens when the permissible motor temperature is exceeded.
The unit switches off when the contact opens. The fan will start again automatically once the motor
has cooled down, i.e. when the contact closes.
No error message is given.
Supply air temperature limit
If there are large temperature differences between the specied set-point temperature and the
measured temperature, this may lead to the introduction of very hot air in the case of room air tem-
perature control. This high supply air temperature can lead to a deterioration of the air quality in the
room. To prevent this, in the case of heating, the supply air temperature is limited to a maximum value
of approximately 35 °C.
Electric heating element
The electric heating element has continuous output control. A safety temperature limiter (STB) swit-
ches the electric heater off, in the event of a fault, when the temperature reaches 75 °C. Once the
safety temperature limiter (depending on model with 2 or 3 limiters) has been tripped, it has to be
reset manually (see Fig. 11). Before resetting the temperature limiters and reinstalling the inserts the
cause for tripping of the STB needs a troubleshooting.
Filter monitoring
After a set time, the lter display reminds you that the air lter has to be changed. A detailed descrip-
tion of changing the air lter is given in Section 10.3.1.
