Why ventilate?
Orcon: exceptional indoor climate
Our goal is to provide residents with an exceptional indoor climate that is as comfortable 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 undergoing 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 CO

room sensors.

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.

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!
