1. Safety
Read this manual carefully before you mount or use the
device. The following icons are used in this manual.
Indicates the risk that the device will be damaged
if the instructions in this manual are ignored.
Indicates electrical voltage.
1. Only a professional installer may install, connect,
commission and maintain the device unless otherwise
specied in this document;
2. The installation of the device must be performed in
accordance with the general and locally applicable
construction, safety and installation instructions of the
municipality and power company;
3. When performing work on the device, ensure that it
is disconnected from the power supply and cannot
be accidentally reconnected. Bear in mind that after
disconnection from the power supply, the motor will
keep running for approx. 20 seconds.
4. The device is only suitable for a 230 V 50 Hz connection;
5. Modication of the device or the specications listed
in this document is not permitted;
6. The device is only suitable for residential buildings and
not for industrial use, such as swimming pools or saunas;
7. The device cannot be opened without the use of tools,
see Chapter 5;
8. This ventilation device creates negative air pressure in
thehome.Itisimportanttoensurethatnoexhaustgases
from a replace, stove or other combustion devices can
be sucked into the home. It is important that an outside
2

air inlet with sufcient dimensions is always provided for
the (open) combustion device.
9. It must be impossible to touch the fans by hand,
therefore ducting at least 900 mm long must be used.
10. Mount the domestic ventilator out of the reach
of children.
11. After use, place this manual, together with the user part
at the front, back into the device;
2. Installing the MVS-15RH
domestic ventilator
The MVS-15RH consists of a suction plenum with ve
Ø 125/160 mm suction openings and one Ø 125 mm
outlet opening. A volute with inlet ring containing
a motor plate with front cover. The connection openings
are provided with caps which can be easily removed.
The motor and the receiver PCB are mounted on the motor
plate. The humidity sensor is on the receiver PCB .
Steps for installing the MVS-15RH
1. Mount the MVS-15RH device on a wall or ceiling with
sufcient mass (200 kg/m2).
2. Install a silencer at least 1 metre long.
3. Mount the air ducts with as little air resistance as
possible, and free from leakages.
4. Limit the use of exible tubes as much as possible.
5. Cap the unused openings on the suction side with the
supplied caps.
6. Mount the Orcon extraction valvesin the various spaces.
7. Mount the required remote control(s) and CO2sensor(s)
(BRH models only)
8. Connect the MVS-15RH device to the power supply.
9. Pair separately supplied remote control(s) and/or CO2
sensor(s).
If there is more than one remote control, always switch the
device on and off before pairing.
10.. Set the DIP switches of the MVS-15RH device on the
receiver PCB, and adjust the valves. See the chapter
‘Adjustment of air volume’.

Installation
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.

MVS-15RHP
This model of the device is powered via a cord with Perilex
(P) plug. Please note! An existing 3-position switch no
longer has any function.
Electrical connection domestic ventilator
The MVS-15RH is equipped with a cord and earthed plug for
connection to the power supply. The device can be switched
to four positions, and is equipped with an automatic mode.
The connection of the device must comply with NEN 1010
and any applicable local requirements. Do not insert the
plug into the wall socket until everything is installed.
The device is not suitable for three-phase current.
Supply voltage: 230 V ~50 Hz.
4. Adjustment of air volume
1. Close the windows and doors.
2. Set the extraction valves and (ZR) grilles to their fully
open positions.
3. Set the device to position 2 or 3 (depending on the size
of the home).
5. Open the front cover of the device with a athead
screwdriver.
6. Set the system to the correct total capacity using the
DIP switches.
4. Measure the total air volume in the Orcon extraction
valves and adjust where necessary.
7. Adjust the extraction valves to the correct ow rate for
each space.
8. Complete the installation report (page 18).
On the receiver PCB, a curve can be set with the DIP
switches for each position. The factory settings are curves
1a, 3a and 11a (* in table A).

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.
