Electrical connections for Norway without transformer, (3x230 VAC)
The power unit can be used without a transformer
in Norway where 3x230 VAC is used. However, the
maximum motor load is lower for each power unit
when using 3x230 VAC; see the table on page 11.
In this case use phase L2 as a virtual neutral. Strap
between L2 and the neutral fuse on the incoming sup-
ply, see connecting on page 9, Fig. 7.
Connect the transformer as illustrated on the right.
Connect the incoming supply 3x230 V to the primary
side and the eQ (400 V) to the secondary side. Position
the transformer so that it has proper ventilation. Maxi-
mum ambient temperature 40°C.

Connecting the service power supply for lighting
All of the air handling unit’s incoming power supplies
must be preceded by a load interrupter in accordance
with Machinery Directive 2006/42/EC. Load inter-
rupters are available as accessories STAZ-80.
In eQ units with integrated controls there are two
options for providing service power for air handling
unit lighting.
1. For power supplies up to 5.5 kW, a service power
supply can be obtained by connecting L3 to L3’
through a terminal block on the power unit in the
control cabinet. This means that the entire air handling
unit is turned off from all power when it is disconnec-
ted through the all pole load interrupter. See Fig. 5.
2. Separate power supply. This means that the air hand-
ling unit still has a service power supply when the all
pole load interrupter is disconnected. See Figs. 4 and 6.
Options 1 and 2 apply if the project’s mains
voltage is 3x400 VAC. If the project’s voltage is
3x230 VAC, connect in accordance with point 2.
In order to achieve service power that takes account
of personal safety in point 2, when the air handling
unit load interrupter is off, the service power must be
supplied from the same group and provided with
a 10 AT double-pole fuse group, and a ground fault
interrupter in series. See Figs. 4 and 6.
If the load interrupter is switched off, service power is
supplied through the residual current circuit breaker,
and when the load interrupter is on, the ground fault
interrupter is bypassed via the load interrupter auxi-
liary contacts.
The service power supply must be connected in ac-
cordance with the enclosed wiring diagram. When
disconnecting the load interrupter, switch off the
double-pole automatic fuse rst, and when the load
has been disconnected the double-pole automatic fuse
can be switched on again. The reverse procedure app-
lies when switching on the load interrupter.

Tip: The frame of the control panel can be turned so that the mounting rail faces downwards on outdoor
units and upwards on indoor units where the incoming supply comes via a ceiling mounted cable ladder.
External components can be easily connected to the eQ unit
through a quick connector or wires to a screw terminal block
in the control cabinet.
Then the cable is routed through the cellular plastic strip on
the air handling unit and secured to the adjacent mounting
rail. When all cables have been connected to the terminal
block, t the control panel cover and secure it using the
screws supplied.
The cellular plastic, which is semi-elastic, will slowly adapt
to the shape of the cables thus sealing the lead-in.
The following paragraphs provide information about how
to install and connect the various sensors and accessories.

SERVICE POWER INPUT
The air handling unit lighting is controlled by a switch
mounted on the cover of the control panel on the air hand-
ling unit. The switch is connected to a quick connector in
the control panel.
Lighting control in the control panel
Connect the power supply for the air handling unit light-
ing via the terminal block on the power unit, see page 4–5.
For 5.5 kW power units, L3 and L3’ are strapped on the
terminal block for the lighting power supply via the air
handling unit power supply. For 7.5 and 11–15 kW power
units, L3 and L3’ are strapped downstream of the fuse,
see pages 4–5. Note that in this case the lighting power
supply is also cut when the air handling unit power
supply is cut. Connect the external power supply to the
lighting in accordance with the wiring diagrams on pages
7-9. This allows lighting even when the power to the air
handling unit is cut.

Temperature sensor
The temperature sensors included, and where they
should be located, is shown in the list of components and
the ow chart in the drawing documentation.
Connect all external temperature sensors to the control
panel via quick-t connectors. The room sensor and exte-
rior wall sensor are supplied without cables, but the other
temperature sensors are supplied with tted cables and
quick connectors to the terminal block. The supply air
sensor, room sensor, exterior wall sensor and the freeze
protection sensor are supplied with the unit but not
installed, while the other temperature sensors are factory
tted in the air handling unit. Obviously these must be
moved if the ow direction on the unit is changed, or if
the air handling unit is converted. The supply air temper-
ature sensor (GT1) should be tted in the supply air duct,
approximately 1.5 m from any duct heaters, to give stable
measurement values.
The outdoor temperature sensor (GT3) for installation
on the facade, is installed centrally on an outside wall, at
least 2.5 m from the ground, on the building in which the
temperature is to be controlled. The sensor should not
be exposed to morning sun or installed above a window,
door or other heat sources. Install the sensor on a wall
that faces north if possible.
The room temperature sensor (GT2) is intended for place-
ment on an interior wall in the room where the tempera-
ture is to be controlled. The sensor should be positioned
in an area with good air circulation and it should not be
exposed to direct sunlight.
The frost protection sensor (GT5) is to be installed on the
heater return pipe when using clamp on sensors and in
the metering socket on the return pipe when immersion
sensors are used. To obtain the correct measured values,
the heat-conducting paste supplied must be applied to
the return pipe when the clamp on sensor is secured onto
the return pipe using cable ties.

The pressure sensor is supplied as a separate accessory.
If pressure control is used, the air pressure in the index
duct is controlled (the duct with the highest pressure
drop and where the static pressure is the lowest). The rst
branch in the duct system is usually the index duct.
The pressure sensor is located at the beginning of this
duct. Position the extract air sensor, GP6, in an appropriate
position with a representative pressure in the extract air
duct. The ow sensors are always tted, even with pres-
sure control.

Wiring (pressure control)
The pressure hose connected to the sensor must have an inner
diameter of 4 mm.
Flow control
The ow sensors are always installed, connected and
congured. The sensors are connected to the connection
board for each fan.
Pressure control, supply air with slave-
controlled extract air
The pressure sensor for the supply air is connected in the
same way as for pressure control, see above. The ow
sensors are always installed, connected and congured.

NOTE! The new pressure range must be entered into the controller when changing the pressure range on the sensor,
irrespective of whether the pressure or flow is being controlled. Read about this in the controller manual.
Zero point-calibration
NOTE! The sensors must be zero calibrated during commissioning.
They should then be zero calibrated annually.
The sensors should have been energized for approximate-
ly ve minutes before calibration is carried out. After that,
remove the hoses from the sensors. To start calibration,
press the button below the dip switches, see the gure.
Release the button when the LED lights.

Temperature correction
The ow scale on the display instrument and ow formula
above apply to air at a temperature of +20°C.
At other air temperatures the ow must be corrected using
the formula:
q = q20
q = the true ow through the fan,
q20 = the ow reading
t = current temperature in °C

Supply 24 VAC, output signal 0-10 VDC, measurement
range CO20-2000 ppm
The CO2-sensor is supplied as a separate accessory.
When installed in the duct position the sensor in the ex-
tract air duct as close to the air outlet as possible.
When installed in a room position the sensor where the
air quality is representative, for example, on an open wall
at a height of 1.5–3 metres. Connect the CO2-sensor to the
same input as the pressure sensor GP6; see the table for
CO2 compensation. If the mixing damper is CO2control-
led connect the CO2 sensor to the Z terminal block.
NOTE! These cannot be connected at the same time!
