Why ventilate?
Orcon: exceptional indoor climate
Our goal is to provide residents with the most comfortable and healthy (extraordinary)
indoor climate possible, in which they feel comfortable and can function optimally.
The importance of good ventilation
Houses are increasingly well insulated. This is a good development, because it
saves a lot of energy and money. However, good insulation does reduce the
exchange of air in your home, because in an airtight home, air cannot flow from the
outside to the inside, or vice versa. And that is not a good thing, because you and
your home need fresh air.
Simply opening a window is not enough; by the time you close it, the fresh air has
already disappeared. You need about 25 m³ of fresh air per hour, so good
ventilation is a necessity. Without good ventilation it becomes damp and musty in
the house, resulting in bacteria, mould and health complaints such as headaches,
allergies and respiratory irritations. Moreover, heating this moist air costs more
energy than heating dry air.
Of course, this is an extreme situation, but a good ventilation system is
mandatory in new houses for a reason. This balanced ventilation system can
operate fully automatically and saves energy. But more importantly, it also
benefits your health!

2. General operation of balanced
ventilation system with zone control
In order to create a healthy living environment in your home, good ventilation is
required. Your house is therefore equipped with an Orcon mechanical supply and
exhaust ventilation system. This system consists of a centrally installed balanced
ventilation unit
(HRC-EcoSmart/SmartComfort) with zone control, 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 sensor(s).

Overview ventilation system HRC-EcoSmart/SmartComfort
In balance
The HRC-EcoSmart/SmartComfort is equipped with two fans: an inlet fan. The
exhaust fan ensures that warm, moist and contaminated air is removed from the house.
The supply fan ensures a sufficient supply of clean outside air.
Heat exchange
The supply air, which in winter will be rather cold due to the cold outside air, is first
heated in the HRC by means of the heat extracted from the warm return air from the
house. Conversely, in the summer months, the warm supply air from outside will be
cooled by the cooler return air from the house.

The built-in heat exchanger ensures that up to 99% of the heat is transferred, which
means that hardly any valuable heat is lost and the inlet temperature is at a
comfortable level.
Zone control
With the zone control on the device, ventilation takes place in the room where
ventilation is required. Smart sensors, placed in the living & sleeping areas,
determine where ventilation is needed. During the night, the ventilation need is
reduced in the living room and increased in the bedrooms. In this case, the device
will ensure that there is reduced ventilation in the living room. And the air supply in
the bedroom is kept optimal.
This makes the HRC-EcoSmart/Comfort very energy-efficient as it only ventilates
the room where it is needed. As a result, the ventilation system is also whisper-
quiet.
Bypass
In the summer situation, when heat recovery is not desired, the air is not led
through, but past the heat exchanger via a bypass valve. This makes it possible to
ventilate the house with relatively cool outside air during the night in the summer,
so that the house is relatively cool again in the morning. The bypass automatically
works at the best moment to achieve maximum comfort.
Frost protection
When the outside temperature in winter is around freezing point, it is possible that
ice will form in the exchanger. The result is that cold air is blown into your home. To
prevent this, the HRC will heat the exchanger in time using the warm indoor air
from your home. To do this, the unit will temporarily turn up the extract air fan at a
higher speed than the supply air fan.
The HRC-MaxComfort has a built-in pre-heater that switches on automatically to
prevent the heat exchanger from freezing.
Moisture sensor
Your HRC is fitted with a humidity sensor as standard, which measures the
moisture content in the extract air from the kitchen, bathroom and toilet. If the
built-in humidity sensor
If the humidity rises, for example while cooking or taking a shower, the unit will
automatically switch to a higher setting. 15 minutes after showering or cooking, the unit
will switch back to the lower setting.

Filters
The HRC is equipped with two filters. A filter for filtering the supply air and a filter
for filtering the return 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 exhaust filter
ensures that the air from your home is also filtered, so that the contamination of the
exchanger remains minimal.
For an optimal indoor climate, we recommend cleaning the filters every 3 months
and replacing them once every 6 months. The HRC is equipped with a filter
indicator, which indicates when the filters need to be cleaned. For more
information about cleaning your filters, see chapter 5.
Attention: Ensure sufficient air supply. Never tape valves together or
close them!
Please contact your installer if you have any questions or if you want to
order new filters. Filters can also be ordered directly in the Orcon
webshop: www.orcon.nl/winkel

Absence mode
In the absence mode, the unit runs in the minimum ventilation mode.
Timer mode
In timer mode, the unit runs for a desired time in position high, after the time has
elapsed the unit returns to the last selected position. The timer can be cancelled by
selecting another (desired) setting.
Automatic mode
In auto mode, the unit runs based on the moisture content in your home.
The moisture sensor is integrated as standard in the HRC and measures the moisture
content in the extract air from the kitchen, bathroom and toilet. If the humidity sensor
detects that the humidity level is rising, the device will automatically switch to a higher
setting. 15 minutes after showering or cooking, the device will switch back to its
previous setting. If your appliance has been upgraded with a CO2 room sensor, the
automatic mode works on the basis of the CO2 content. The system can be expanded
with additional controls/CO2 room sensors (up to a maximum of 20 controls per
appliance).
4.3.Control with the CO2 room sensor
This sensor measures the CO2 concentration (air quality) in the room and automatically
increases ventilation when necessary. This prevents unnecessary ventilation, which
benefits the energy efficiency of the device.
Indication and operation CO2 room sensor
By touching the operating button once, the status is shown by the LEDs. After 30
seconds the LEDs switch off automatically to avoid disturbing a dark room. If the
operating button is pressed again, the sensor switches to a different mode. The
mode change is indicated 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
provided when it is actually needed.
• Extraordinary mode
When in this mode, the CO2 room sensor will keep the air quality at a high
level. This will increase ventilation, removing the dirty air particles from the
house and bringing in fresh air from outside.

13
4.4.Control with the CO2 built-in sensor
This built-in sensor measures the CO2 concentration (air quality) in the room and
automatically increases ventilation when necessary. This prevents unnecessary
ventilation, which benefits the energy efficiency of the device.
Indication and operation with the CO2 built-in sensor
By pressing the operating button once, the status is shown by the LEDs. After 30
seconds the LEDs switch off automatically to avoid disturbing a dark room. If the
operating button is pressed again, the sensor switches to a different mode. The
mode change can be recognised by the LED's lighting up.

The CO2 built-in sensor has the following modes:
•Absence and positions 1, 2 and 3
When the CO2 recessed sensor is in the off position, the unit will ventilate a
minimum amount. Only the Status LED lights up and goes out after 30
seconds. This mode remains active for 12 hours.
Mode 1 (low), 2 (medium) and 3 (high) are temporary modes. If modes 1 (low) and
3 (high) are selected, the system will return to automatic mode after 60 minutes
and the LEDs will remain on during this time. For setting
2 (middle) is 13 hours, this setting can be chosen as a night setting in situations
where not every bedroom is equipped with a CO2 sensor.
•Energy-saving mode
When the CO2 built-in control sensor is in this mode, the fan will ventilate according
to the standard requirement. This saves on energy costs, as ventilation is only
provided when it is really needed.
•Extraordinary mode
When it is in this mode, the CO2 built-in sensor keeps the air quality level at a very
good level. As a result, more ventilation takes place, which means that the dirty air
particles are removed from the house more quickly. The clean outside air is brought
inside.

16
4.5.Operation with CO2 control sensor
The HRC can also be operated with the CO2 control sensor. This is a CO2 sensor with
integrated control. By touching the control button once, the LEDs indicate the
status. After 30 seconds the LEDs will automatically switch off again, in order not to
disturb a dark living room. If the control button is pressed again after being pressed
once, the CO2 control sensor switches to a different mode.
CO2 Plus system
It is possible to place a CO2 room sensor, flush-mounted sensor and/or flush-
mounted display or control sensor in each occupied room. This can be extended
to up to 15 CO2
Room sensors (and 5 remote controls). These sensors communicate wirelessly with
the HRC-EcoSmart/SmartComfort ventilation unit.

When the remote control is set to automatic mode, the unit responds to the highest
CO2 level (air quality in a residential area) measured by the CO2 room sensors. This
provides fully automatic control, ensuring an exceptional indoor climate for the
occupant at all times. You can always choose a different speed with the remote
control. The automatic mode will then lapse. After any power outage, the fan will
start in the automatic mode.
