2. Product information
2.1 General product description
The HRC is a balanced ventilation system with heat recovery. This means that an equal
amount of fresh filtered outside air is supplied to the living room and bedrooms while
polluted air is extracted from the kitchen, bathroom and toilet. The heat of the extract
air from inside is then transferred to the fresh filtered outside air. This results in
significant energy savings.
The Orcon HRC is equipped with an intelligent electronic control circuit that ensures
optimum operation and protection under all circumstances. The unit can be used as
a left or right model. The unit is supplied as standard as a left model with a grounded
plug and can be converted to a perilex model with a perilex power cord (article num-
ber: 22915405). For all models it is possible to use a radio remote control 15RF, CO2
Roomsensor 15RF or a CO2 Controlsensor 15RF; these are available separately.

3.2 Operation
Bypass
In the summer, or when heat recovery is not desirable, the air is not passed through,
but past the heat exchanger thanks to a bypass module. This makes it possible to
ventilate the home with fresh outside air in the summer situation, during the night,
so that the home is relatively cool again in the morning. The bypass opens when the
inside temperature exceeds the set comfort temperature of 23°C and the outside
temperature exceeds 15°C.
Frost protection
When the outside temperature in winter is around freezing, it is possible for ice to
form in the exchanger. Cold air is blown into your house as a result. To prevent this,
the HRC will heat the exchanger in time using the warm indoor air from your home.
The unit will temporarily create an imbalance to achieve this.
For the MaxComfort models, the built-in preheater switches on and warms up the cold
incoming outside air.
Constant volume
The unit is equipped with a constant volume control. This ensures that deviations
in the air flow rates between the supply and extract air, for example due to weather
conditions or when the filters become contaminated, are corrected automatically.
In this way the unit remains constantly balanced and you are assured of sufficient air
with maximum efficiency.

4.4 Electric connectors
The HRC is equipped with a earthed
power cord as standard. Optionally,
you can replace the earthed power
cord with a perilex cord (article
number: 22915405).
The place where the wall socket
needs to be fitted is indicated in
the figure below. The electrical
installation must comply with
NEN1010 and the requirements
of the local energy company.
• Only place the plug in the
wall socket when the entire
installation is ready and no
building material is present
• The unit is not suitable for
3-phase current
• Supply voltage:
230 Volt ~50 Hz
Fitting the HRC with a perilex cord
Caution: ensure that the unit is always disconnected from the power supply
when changing the earthed power cord.
If you want to replace the earthed power cord with a perilex power cord, follow these steps:
1. Place the unit on a flat surface.
2. Remove the earthed power cord from the cable clamp on the metal rear frame
3. Remove the printed circuit board cover on the top of the unit by unscrewing the 2
screws using a Torx screwdriver (key size T25)
4. Remove the connector from connection X27
5. Remove the earthed power cord from the cable recess.
6. Using a flat screwdriver, attach the black wire of the perilex cord to position 2

8. Place the white connector of the perilex cord on connection X27.
9. Feed the perilex cord through the cable recess. Place the strain relief in the
appropriate recess.
10. Screw the strain relief hand tight using a Torx screwdriver (key size T20)
11. Replace the top cover and re-tighten the 2 screws
12. Reinsert the earthed perilex cord into the cable clamp on the metal back frame
13. Place the plug in a perilex wall socket which is connected as shown in the
diagram below.
Speed control for perilex connection
A 230 Volt power supply (terminals L3 and N) must be
connected to the perilex wall socket. The speed is con-
trolled by means of a 3-position switch, which receives
power (L3) from the perilex socket (wire diameter 1.5
mm)2). A black (L2) and grey (L1) wire leads from the
switch back to the perilex wall socket. It is important
that terminal L3 is always supplied with voltage. For
the correct way to connect the cabling, see the wiring
diagram below. Optionally, an RF Remote Control, CO2
Controlsensor or a CO2 Roomsensor can be combined
with the CV-3 switch. If several switches or controls are
used in the home, the last selected ventilation position
always takes precedence.

Wall mounting
The unit can be hung on the supplied wall bracket. But only if the wall has a minimum
mass of 200 kg/m2 is available.
1. Attach the wall bracket to the wall using the bolts and plugs supplied. Caution:
mount the wall bracket using a spirit level before you connect the ducts!
Sufficient space must be left underneath the wall bracket for the condensation
extractor (see chapter 4.7).
2. Place the HRC in the left or right configuration over the wall bracket, by hooking
the hook on the back of the unit over the wall bracket.
3. Turn the levelling feet on the back of the unit so that it hangs level against the
wall. This ensures that the condensation extractor works optimally.

Floor mounting
If there is no wall that is suitable for wall mounting, the HRC can also be placed on
a concrete floor using the optional Orcon base (article number: 22700080) for floor
mounting.
1. Place the legs in the recesses on the bottom of the unit (Figure A). This works best
when the unit is on its side.
2. If necessary, use a spirit level to adjust the levelling feet so that the unit is level on
the floor (Figure B).
A. B.
4.6 Connecting ducts to the unit
Once the unit is fitted, the ducts can be mounted. The ducts (return) from and to
the home (supply) are on one side of the unit, and the ducts from and to the outside
are on the other side. In order to prevent condensation on the ducts from and to the
outside, these must always be insulated externally to ensure that they are damp-
proof. It is preferable to use preinsulated plastic ducts made of PE or PUR. Try to keep
these ducts as short as possible.
It is advisable to connect the ducts to and from the home to the unit using sound
dampers with a minimum length of 100 cm. When measuring the ducts, bear in mind
that not too much energy is lost when transporting the air through ducts that are
too narrow. It is preferable not to have the total resistance of both the supply system
and the discharge system exceed 100 Pascals. The supply duct system must be fitted
in such a way that NEN 1070, table 4 is complied with in the nominal setting. Think
of crosstalk and installation noise, also with underfloor ducts. Ensure that the supply
ducts are insulated if necessary, e.g. if they are installed outside the insulated skin.
Attention: make sure no residual material is able to reach the device while
installing the pipes to prevent it from damaging the device.

4.7 Condensation extractor
The HRC must always be fitted with a condensation extractor underneath the unit.
It is preferable to use a dry siphon (article number: 22700065), which can be ordered
separately. Because this requires less space underneath the unit, there is less chance
of air leaks and it does not dry out on hot days, which prevents odour issues. When
connecting the siphon, always use PFTE tape to prevent leaks.
Standard siphon
The unit is supplied with a standard 32 mm connector with threaded end. This can be
connected to the bottom of the unit on internal thread (G1 ¼"). The condensation water
must be extracted through the inner sewer system free of frost and on a slight incline.
A water trap of at least 80 mm must be installed to prevent an air leak and sewer
odour from spreading into the ventilation system. A siphon with a diameter of 40 mm
must be placed under the water trap. Preferably use a threaded connector and rubber
gasket for easy cleaning of the siphon. When connecting the siphon, always use PFTE
tape to prevent leaks.

5. Installation components
5.1 Remote control 15RF (optional)
Mounting
The remote control can be opened using the push button at the bottom (image
below). The wall frame can then be mounted with the 2 screws and plugs supplied
or glued. Caution: the "UP" mark on the wall frame must always be at the top. Keep
enough space at the bottom so that the push button can be easily reached from
below. It is recommended to place the remote control in an easily accessible place
in the living room, kitchen or toilet. Never place the remote control near large metal
objects. Large metal objects can disrupt the radio-controlled signal.
Battery position
Push button open control
Registration
The remote control must be registered. In total, up to 20 RF components can be
connected to the unit.
• On 1 unit
Unplug the unit from the wall outlet for 10 seconds. Then put the plug back
in the socket. The unit will remain in set-up mode for 3 minutes and you can
register the remote control. Press the keys <1> and <auto> simultaneously until
the LED on the remote control flashes red, green and red alternately. The LED
on the remote control will now flash green 10 times, the remote control is ready
for use. Registering an extra remote control is done in the same way.
• On multiple units
To register 1 remote control on more than one unit, the above registration
procedure is repeated, just press the key <2> and <auto> until the LED on the
remote control flashes alternately red, green and red.

• Resetting remote control 15RF
To replace a remote control, all components on the unit must be de-registered.
All components must then be registered again. A remote control can be reset
(and thus de-registered) by simultaneously pressing the ‹absent› and ‹timer› keys
for 3 seconds. The remote control indicates that the reset is complete when it
flashes orange twice.
Remote control
The remote control for the unit has 6 buttons. The functions of these buttons are
explained in the table below.
• Absent setting
In the absent position, the unit runs in an extra energy-efficient low setting and
does not respond to demand from the sensors.
• Timer setting
In the timer mode, the unit runs the desired time in the high position, after the
time has elapsed, the unit returns to the last selected position. The timer can be
cancelled by selecting another setting.
• Automatic mode
In car mode, the unit runs based on the moisture content in the home or based
on the optional CO2 sensors. If there is no ventilation demand, the unit runs as
standard in position 1. When there is a ventilation demand from the humidity
sensor or the optional CO2, the unit will modulate the ventilation to the medium
setting (setting 2).
