Why ventilate?
Orcon: exceptional indoor climate
Our goal is to provide residents with an exceptional indoor climate that is as com-
fortable and healthy as possible, in which they feel comfortable and can function
optimally. With this aim in mind, we have grown to become a leading supplier of
ventilation systems for residential homes and utilities.
The importance of good ventilation
Houses are becoming better insulated. This is a positive development, because it saves
a great deal of energy and money. Unfortunately, good insulation reduces the fresh
air supply in your home, because in an airtight home the air cannot circulate from the
outside to the inside, or vice versa. This is an unwanted side-effect that comes with a
properly isolated home. As you need enough fresh air in your home the airflow needs
to be constant.
You require approximately 25m² of fresh air an hour, so good ventilation is a necessity.
Just opening a window isn't enough to solve the issue. As closing it would mean you
cut of the airsupply again.
Without proper ventilation, it will get damp and musty in your home, allowing
bacteria and fungi to grow with health problems such as headache, allergies and
respiratory irritations as a result. Moreover, it is also true that heating this moist air
consumes more energy than heating dry air.
Of course we are illustrating an extreme situation, but a good ventilation system is
mandatory in new houses for good reason. This balanced ventilation device can operate
fully automatically and saves energy. But more importantly, it also benefits your health!
It is therefore important to ventilate your home 24 hours a day.

1. Precautions and safety instructions
This document will assist you to operate and maintain the HRC safely and optimally.
The HRC is referred to as "the unit" in this document. The unit is continuously under-
going further development and improvement. This means that there is a possibility
that the unit may deviate slightly from the descriptions.
Contact your installer if you have any questions or would like to order new filters.
1.1 Safety instructions
• Installation, commissioning and maintenance must be carried out by an
approved installer, unless indicated otherwise. An unauthorised installer can
cause personal injury or damage the functioning of the ventilation system;
• After installation, all parts that may lead to personal injury are safely contained
inside the housing. Do not open the housing;
• Always follow the safety instructions, warnings, comments and instructions
in this manual. Failure to follow safety instructions, warnings, comments and
instructions may result in personal injury or damage to the unit;
• Modifications to the device or the specifications in this document are strictly
prohibited. A modification may cause personal injury or damage the functioning
of the ventilation system;
• Do not disconnect the plug from the socket unless specified in the unit manual.
This prevents the occurrence of moisture and mold problems.
• Replace the filters at least every six months. This keeps the indoor air healthy and
comfortable and protects the unit against dirt;
• Always keep the user manual near the unit. The next installer who needs the
manual will know where to find it.

2. General operation of balanced ventilation system
In order to create a healthy living environment in your home, good ventilation is
required. Your home is therefore equipped with a mechanical supply and extractor
ventilation system from Orcon bv. This system consists of a centrally arranged balance
ventilation device (HRC-EcoMax/MaxComfort) with very energy-efficient DC motors,
a duct system with supply and exhaust valves in the various rooms and can be
combined with a position switch, an RF remote control and/or CO2 room sensors.

In balance
The HRC-EcoMax/MaxComfort is
equipped with two fan modules:
an extractor ventilator and a supply
ventilator. The extractor ventilator
ensures that warm, humid and contaminated air is removed from the home.
The supply ventilator ensures a sufficient supply of clean outside air, which will pass
the filters before entering your home. This to ensure clean air enters your living space..
Heat exchange
The supply air, which will be quite cold in the winter due to the cold outside air, is first
heated in the HRC using the heat extracted from the warm return air from the home.
Conversely, in the summer months the warm supply air from outside will be cooled by
the cooled return air from the home.
The built-in heat exchanger ensures that up to 99% of the heat is transferred, so that
hardly any valuable heat is lost and the inlet temperature will be at a comfortable level.
Overview ventilation system HRC-EcoMax/MaxComfort

6
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.
Humidity sensor
Your HRC is equipped with a moisture sensor, which measures the moisture content in
the extracted air from the kitchen, bathroom and toilet. If the built-in humidity sensor
detects that the humidity is rising, for example during cooking or showering, the unit
will automatically switch to a higher setting. The unit will switch back to the lower
position 15 minutes after showering or cooking.
Filters
The HRC has two filters. A filter for filtering the supply air and a filter for filtering the
extracted air. The supply filter ensures that only clean air enters your home and that
dust, soot and insects remain outside. Optionally, you can also use a pollen filter for
the supply filter. The extractor filter also ensures that the air from your home is filtered,
so that the pollution to the exchanger is kept to a minimum.
For an optimal indoor climate, we recommend that you clean your filters every 3 months
and replace them once every 6 months. The HRC is equipped with a filter
indication, which indicates when the filters must be cleaned. For more information
about cleaning your filters, see Chapter 5.
Caution: Ensure adequate air supply. Never tape or close the valves!

4. Operating the unit
4.1 Operation with 3-position switch
If your unit is equipped with a perilex connector and 3-position switch, the ventilation
positions can be set from the table below. If several switches or controls are used in
your home, the last selected ventilation position always takes precedence.
Explanation of Ventilation settings
Setting 1 Low Absent setting For use during absence during a long
period
Setting 2 Medium Present setting For daily use with normal use within
the home
Setting 3 High High setting For use during cooking, showering
or parties
4.2 Operation using RF remote control
The balance ventilator can be operated using a wireless remote control (15 RF). The
remote control has 6 buttons, the functions of which are explained in the table below.

Absent setting
In the absent setting, the device runs in the minimum ventilation setting.
Timer setting
In the timer mode, the unit runs at the high setting for a required time; after the time
has elapsed, the unit switches back to the last selected setting. The timer can be
cancelled by selecting a different required setting.
Automatic mode (auto)
In auto mode, the device runs based on the moisture content in your home.
Your HRC is equipped with a moisture sensor, which measures the moisture content in
the extracted air from the kitchen, bathroom and toilet. If the humidity sensor detects
that the humidity is rising, the unit will automatically switch to a higher setting. The
unit will switch back to the lower position 15 minutes after showering or cooking.
When your device is expanded with a CO2 Room sensor, the automatic mode works
based on the CO2 level. The system can be expanded with extra controls/CO2 room
sensors (up to a maximum of 20 controls per unit).
4.3 Control using the CO2 Room sensor
This sensor measures the CO2-concentration (air quality) in the room and makes the
unit ventilate more if necessary. This avoids unnecessary ventilation, which benefits
the energy efficiency of the unit.
Indication and operation CO2 Room sensor
By tapping the control button once, the status is displayed by the LEDs. After 30
seconds, the LEDs go out automatically, so as not to disturb a dark living space. If the
remote control button is touched again after holding down once, the CO2 room sensor
will switch to another mode. Changing this mode can be recognised by the green or
blue LED on the top right of the CO2 room sensor lighting up.
The CO2 room sensor has the following two modes:
• Energy-saving mode
When the CO2 Room sensor is in this mode the unit will ventilate according to the
standard requirement. This saves on energy costs, as ventilation is only carried
out when it is really needed.
• Excellent mode
When the CO2 Room sensor is in this mode, the CO2 Room sensor to keep air
quality at a high level. As a result, more air is ventilated so that the dirty air particles
can be extracted from the home faster and clean outside air is circulated.

10
4.4 Control using the CO2 control sensor
The HRC can also be operated with the CO2 Control sensor. This is CO2 sensor has an
integrated control. By holding down the control button once, the status is displayed by
the LEDs. After 30 seconds, the LEDs go out automatically, so as not to disturb a dark
living space. If the remote control button is pressed again after holding down once,
the CO2 Control sensor will switch to another setting or mode.

CO2 Plus system
It is possible to have a CO2 Room sensor and/or Control sensor in every living space.
The number can be expanded to 15 CO2 Room sensors (and 5 remote controls).
These sensors communicate wirelessly with the HRC-EcoMax/MaxComfort
ventilation device.
When the remote control is set to automatic mode, the unit responds to the highest
CO2 level (air quality in a living space) that is measured by the CO2 Room sensors.
This ensures a fully automatic control with an excellent indoor climate for the resident
at all times. You can always choose a different speed yourself with the remote control.
The automatic mode is then cancelled. If there is a power failure, the ventilator will
start up in automatic mode.

1. Remove the filter handles, this may require some force.
2. Remove the contaminated filters from the device using the pull tab.
3. Vacuum clean the filters on the outside. If the filters are too dirty, they must be
replaced. Order original Orcon filters to guarantee a good performance of the unit
(www.orcon.nl/winkel).
• Coarse 45% filter: Wire-frame filter, filters 45% of all particles (0.97-176μm)
from the air
• Coarse 65% filter: Pleated filter: large filter surface, filters 65% of all particles
(0.97-176μm) from the air
• ePM1 70% filter: Pleated filter: large filter surface, filters 70% of all particles
(0.3-1μm) such as pollen and fine dust from the air. To be used as a supply
filter.
4. Reinstall the cleaned filters. Caution: Reinstall the filters on the same side as they
were before cleaning. If you have pleated filters (HRC-MaxComfort), an icon will
indicate on which side they should be placed, these icons can also be found on
the top of the unit.
5. Replace the filter handles in the recess on the front of the unit. On the inside of
the covers you will see an 'L' or 'R' marking to indicate on which side the covers
should be. Press the filter handles firmly over the entire front surface to ensure

Caution: Do not throw empty batteries into the household waste, but take them to
the collection points for chemical waste.
Maintenance CO2 Room sensor/Control sensor
The CO2 Room sensors require no maintenance during the lifetime. However, the
operation may be disrupted by contamination of the air slots. Therefore, remove the
dust from the housing regularly with a dry cloth. When a deviation occurs in the CO2
Room sensor, then the status LED will light up red continuously. In this case, contact
the installer.
Fill condensation extractor
The condensation extractor is connected to the indoor sewage system. If a standard
condensation extractor is installed, sewage air can enter your home if there is no
water in the water trap. You can prevent this by pouring a cup of water into the water
trap. If a flat dry siphon is used, you do not need to do anything, it will not dry out.
