10. ASSEMBLY

Assembly work may only be performed by specialist personnel in accordance with the installation and operating ma-

nual and the regulations and standards in force.

e following points should be noted and followed:

■Mount and align the unit with the aid of a water level. Only if the machine is horizontally installed can proper con-

densate drainage be guaranteed.

■Only suitable installation aids, in accordance with regulations, should be used.

■e device must be installed in such a way that it is easily accessible for maintenance and cleaning purposes.

■e unit should only be installed with authorized and suitable fastening materials at all fastening points.

■Do not distort the unit when installing.

■e unit should be suitably secured.

■Just use the indicated mounting and ﬁxing places. No holes should be made in the housing or any screws screwed

into it.

■e duct system must not be supported on the housing.

■It is recommended that the duct system is attached with ﬂexible connections or connection collars in order to

isolate any structure-borne noise. For ﬂoor or wall mounting, all units should be mounted to isolate structure-borne

noise.

■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 malfunc-

tion of the unit.

■e pressure loss in the duct system must not exceed the capacity of the unit! e 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. is will

prevent malfunction. Pressure losses in the duct system are adversely aﬀected by: the length of the duct system,

small duct cross-section, elbows, additional ﬁlters, valves, etc.

11.2. Description external inputs and outputs

11.2.1. Inputs

Unit enabling

e 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. e control system would be destroyed. Any devices providing a potenti-

al-free contact (e.g. central building control system) can be used to control the unit. is contact must be securely

isolated from external voltages because otherwise dangerous conditions might occur in the event of a fault.

e extra-low voltage control cables must be laid separately from the mains cables.

Motion detector

A motion detector can be connected to the controller. When the contact is closed, the unit goes into „Party“ mode for

the overrun time set in the „Functions“ menu. External, potential-free contact.

Fire detector

An external, potential-free ﬁre detection contact switches the device oﬀ. e control unit display shows „Fire protecti-

on fault“. is signals requires a manual reset.

Frost protection via supply air sensor

If the supply air temperature drops below 4°C, the unit goes into the preheating mode. e dampers are closed, the

fans are switched oﬀ, the circulation pump is switched on and the heating valve is opened. If the supply air tempera-

ture is still below 4°C after 20 minutes, the system switches oﬀ completely and the fault message F7 Frost protection

appears on the control panel. e circulation pump remains switched on and the heating valve opened. If the supply air

temperature rises again within 20 minutes, the device returns to normal operation.

Optional frost protection thermostat

An external frost protection thermostat can be connected to the controls. As soon as the temperature drops below the

set value, the dampers are closed, the fans are switched oﬀ, the circulation pump is switched on and the heating valve

is opened. If the set value is not reached after 20 minutes, the system switches oﬀ completely and the fault message

F7 Frost protection appears on the control panel. e circulation pump remains switched on and the heating valve ope-

ned. If the supply air temperature rises again within 20 minutes, the device returns to normal operation.

External 0 - 10V input

An external measuring transducer can be connected to the 0 - 10V input for demand controlled ventilation.

Unit supply cable

Connect the mains supply cable as shown in the wiring diagram. For the dimensioning of the line, observe the unit‘s

rating plate and the relevant guidelines. Appropriate protection with correctly dimensioned automatic safety breakers

(circuit protection breaker) must be provided.

e device must be connected according to the wiring diagram. For fans which are controlled by external control de-

vices, the corresponding operating instructions of the manufacturer must be observed.

Enable circulation pump heating

A circulation pump can be connected to the controller (see circuit diagram). If heating is required, the heating valve is

opened by the controller and the circulation pump output is activated. Any pump connected must be inherently safe

and block-proof.

Electrical connection with Vmax =230 VAC and Imax=2 A.

12. COMMISSIONING

Commissioning by trained technical personnel may only be performed after any risk has been ruled out. e

following checks should be performed in accordance with the installation and operating manual and the regu-

lations 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.

■e 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.

■e 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.

11.2.3. Interfaces

Control unit

e control unit is connected to the supply air unit‘s control system with a control cable. Max. cable length 100 m.

A connector on the control cable is plugged directly into the socket on the control unit from beneath (see Fig. 13-1 ).

On the unit, the control cable is ﬁrst fed through a cable gland (see Fig. 11-1), placed in the cable duct and then connec-

ted to the RJ10 socket provided in the controller board. e 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. is 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).

Modbus RTU

e communication interface with Modbus RTU protocol is already integrated as standard. e central building control

system can be connected directly to the integrated interface via Modbus.

3-way valve heating

Temperature control for the optional warm water heating coil, e.g. active heating to cover the heating demand by the

ventilation system. Control output 3-position. Control output 230V.

3-way valve cooling

Temperature control for the optional cold water cooling coil, e.g. active outdoor air cooling by the ventilation system.

Control output 3-position. Control output 230V.

Unit malfunction

If there is a unit malfunction, 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. (ere is not any double insulation on the mains cables).
