The installation must be implemented with as little
resistance as possible in the ducts. Long exible tubes
must be avoided. The caps must not be removed from any
unused inlets. The device is mounted to the wall or ceiling
with the four supplied screws and plugs.
Rear connections
At the rear of the suction plenum, an opening is prepared
for rear connections directly to the wall or the ceiling.
If these connections are used, the gap must be opened
with a Stanley knife. The plenum box can be sealed using
sealing tape (not included).
When using the Ø 160 mm connection under or behind the
unit, cut the adapter/pyramid away with a Stanley knife.
Mounting RF remote control (MVS-15RHB)
The remote control can be opened via the push button (see
gure 6), which is located on the underside. The wall frame
can then either be mounted with the 2 supplied screws and
plugs or be stuck in place. Please note: "UP" is marked on
the mounting frame, when mounting make sure that this is
at the top. Keep enough space free around the underside
so that the push button can be easily reached from below.
It is recommended that the remote control is installed in an
easily accessible place in the living room, kitchen or lavatory.
Never install the remote control near large metal objects,
and keep the remote control out of the reach of children.

5. Conguration and pairing
The MVS-15RH is equipped with a receiver PCB on the
motor plate. A separate remote control and/or CO2room
sensor must be paired with the receiver PCB.
Device start up
When the device is connected to the power supply: during
start up, the LED on the device ashes alternately red,
green, red. Then the LED on the device turns green for
3 minutes, during which time the device is in learning
mode and can be linked to a remote control or CO2room
sensor. The MVS-15RH always starts up in automatic mode.
The MVS-15RH is also equipped with a humidity sensor. This
is integrated in the ventilation cabinet. A number of settings
for the functions of this sensor are possible.
DIP switch 8 = OFF / Normal setting.

Fig. 8 DIP switches set to OFF in MVS-15RH

In automatic mode, the MVS-15RH will switch to position
2 when humidity levels increase. The time that the domes-
tic ventilator continues to operate in this mode depends
on the setting of DIP switch 8 and the duration of the
increased levels of humidity.
Pairing remote control(s) to 1 device
The remote control is paired with the MVS-15RHB (CO2) at
the factory. Up to a total of 20 components can be linked
to the device.
Pairing extra remote control(s)
Remove the plug of the device from the power point for
5 seconds. Then reinsert the plug into the power point.
The LED on the device ashes alternately red and green,
after which the LED remains green. The device will be in
learning mode for 3 minutes. During this time, you can pair
remote control(s) by pressing the buttons <1> and <auto>
simultaneously until the LED on the remote control ashes
alternately red, green, red. When the remote control has
been successfully paired, the LED on the device and remote
control will ash green 10 times, and the device will briey
accelerate. The remote control is now ready for use.
Reset remote control
A remote control can be reset by pressing the ‹absent› and
‹timer› buttons simultaneously for 3 seconds. The remote
control indicates that the reset is complete by ashing
orange twice.
Setting the CO2room sensor
The CO2room sensor is paired with the MVS-15RHB CO2
at the factory.
Connect the CO2room sensor to the power supply. During
start up of the CO2room sensor, the orange, green and
blue LEDs light continuously. The LED on the CO2room
sensor ashes red when it is not paired. When the CO2
room sensor is paired, the status LED will turn and stay
green. The CO2room sensor is now ready for use.
Pairing extra CO2room sensor(s)
Remove the plug of the device from the power point for
5 seconds. Then reinsert the plug into the power point.
The LED on the device ashes alternately red and green,
after which the LED remains green. The device remains
in learning mode for 3 minutes. Briey press the control
11

button on the CO2 room sensor once, the red LED ashes.
Then press the button for 7 seconds until the blue LED on
the CO2 room sensor lights up and the status LED ashes
alternately red and green. When the CO2room sensor has
been successfully paired, the green LED on the device and
on the CO2 room sensor will ash 10 times as conrma-
tion, and the device briey accelerates to the high level.
The CO2room sensor is now ready for use. Pairing an
additional CO2room sensor is carried out in the same
way as pairing CO2room sensor number 1.
Unpairing remote control(s) and CO2room sensor(s)
on the device
Remove the cover from the device. Press the push button
on the receiver PCB in the device for 15 seconds until the
LED turns orange. Release the push button. After release,
the LED on the receiver PCB ashes alternately red, green,
red. Any connections with the remote control(s) / CO2
room sensor(s) are now deleted and the factory settings
are loaded. The LED on the receiver PCB remains green
for 3 minutes, during which time the device is in learning
mode and can be linked to components.
Reset CO2room sensor
A CO2room sensor can be reset to factory settings by
pressing the control button for 11 seconds until the LED is
simultaneously red and green (orange). Release the push
button. The CO2room sensor is reset and restarts.

Humidity sensor maintenance
The humidity sensor (g. 11 and g. 12) can be cleaned with
a dry brush.
Removing and installing volute
The volute can be detached from the suction plenum by
gently pulling it out. You can now clean the suction plenum
(g. 13).
Indication LED on the device
The green LED on the receiver PCB indicates the scenario
status of the MVS-15RH. When the LED repeatedly ashes
green once, the MVS-15 is operating normally. If the
LED repeatedly ashes green twice, the MVS-15RH is in
position 2 or 3 due to increased humidity levels. If the LED
repeatedly ashes green three times, the MVS-15RHB CO2
is in position 2 or 3 due to increased CO2levels. If the LED
repeatedly ashes green four times, the MVS-15RHB is in
position 3 due to the timer scenario.
A short orange ash indicates that a signal has been
received from a CO2room sensor or remote control. The red
LED indicates a fault code on the device.

1. General introduction
Orcon exceptional indoor climate?
Our objective is to offer occupants an exceptional indoor
climate which is as comfortable and healthy as possible,
where people can feel at ease and function at their best.
With this aim, we have grown into a leading supplier of
ventilation systems for residential and nonresidential
buildings.
The importance of good ventilation
MVS stands for Mechanical Ventilation System
The system can operate fully automatically, and it saves
energy and money. As an additional benet, it is good for
your health! You need approximately 25 m3of fresh air
per hour, so good ventilation is simply a must. Without
good ventilation, a home becomes damp and musty. This
attracts mould and house dust mites. Poor ventilation
means damp patches in walls and ceilings are a certainty,
as well as health problems such as headaches, allergies
and respiratory irritations.
We are, of course, outlining an extreme situation, but there
are excellent reasons why good ventilation systems are
compulsory in new houses. You and your home need fresh
air! Opening a window for a bit is not enough. The moment
you close the window, the fresh air disappears.
Houses are increasingly well insulated. However you look
at it, this is a positive development, because it saves a lot
of energy and money. Unfortunately, good insulation does
reduce the refreshment of air in your home, because in an
airtight house air cannot from pass from the outside to
the inside, or vice versa. And that is not a good develop-
ment at all, because you and your home need fresh air.
There is a lot of moisture in a house, and its occupants
also produce moisture. Without proper ventilation, humi-
dity and stale air remain contained, with bacteria and
