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 number: 22915405). For all models it is possible to use a radio remote control 15RF, CO
Roomsensor 15RF or a CO
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.

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 controlled by means of a 3-position switch, which receives
power (L3) from the perilex socket (wire diameter 1.5
2
mm)
). 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, CO
Controlsensor or a CO
Roomsensor can be combined

Wall mounting
The unit can be hung on the supplied wall bracket. But only if the wall has a minimum
mass of 200 kg/m
2
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.
index
15
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 dampproof. 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.
