2. Product Information
2.1.General Product Description
The HRC-EcoSmart / SmartComfort is a balance fan with heat recovery and zone
control. This means that the same amount of fresh, filtered outside air is supplied
to the living rooms and bedrooms as is removed from the kitchen, bathroom and
toilet. In this process, only the heat of the extract air is transferred to the incoming
outside air by means of a heat exchanger. With the zone control, the living and
sleeping areas are ventilated according to requirements, which are determined by
the CO2 sensor in the respective area.
2.2.Device types
The table below lists the different versions. Each version is suitable for both left and
right-hand mounting.
1 In accordance with Article 3.29 Paragraph 5 of the 2012 Building Decree

3.2.Appliance operation
Zone control
The HRC-EcoSmart and HRC-SmartComfort are equipped with two zone valves.
With these, the supply air can be divided over two different zones. The CO2 sensors,
which are placed in the two zones, determine where ventilation is required. By
applying zone control, ventilation is minimised in rooms where it is not necessary
and maximised where it is. This results in a considerable reduction in energy
consumption and noise, creating a pleasant indoor climate.
Bypass
In summer situations, or when heat recovery is not desired, the air is not led
through, but past the heat exchanger thanks to a bypass module. This makes it
possible to ventilate the house with fresh outside air during the night in summer, so
that the house is relatively cool again in the morning. The bypass opens when the
indoor temperature exceeds the comfort temperature of 23°C and the outdoor
temperature is higher than 15°C.
Frost protection
When the outside temperature is around freezing point in winter, it is possible that
ice will form in the exchanger. To prevent this, the HRC will heat the exchanger in
time using the warm air from the house. To do this, the unit will temporarily create
an imbalance between the supply and return air fans.
In the SmartComfort versions, the built-in pre-heater will kick in and temporarily warm
up the cold incoming outside air to prevent freezing.
Constant volume
The fans are equipped with a constant volume control. This ensures that,
regardless of the resistance in the system, the fans always ventilate the set air
volume. In this way, the supply and return flows are always balanced and the user is
assured of sufficient air and the heat exchanger operates at maximum efficiency.

Please observe the following points when installing the channels:
1. To prevent condensation on the ducts from and to the outside, these should
always be insulated externally vapour-tight to the appliance. Preferably
pre-insulated plastic channels made of PE or PUR are used, try to keep these
channels as short as possible.
2. It is recommended to install silencers with a minimum length of 100 cm
on the supply and return channels to the house.
3. Attach the duct system to the wall with metal brackets, with a maximum
distance of 2 m between the brackets.
4. Ensure that the resistance in the supply and extract air ducts is as low as
possible. The resistance of the entire installation should preferably not
exceed 100 Pa.
5. Ensure that the duct diameter corresponds to the desired flow rate in the ducts,
so that the air velocity in the duct does not exceed 3 m/s See table in section
4.3.
6. The supply air duct system is designed so that NEN 1070, table 4, is
complied with in the nominal position. Consider crosstalk and installation
noise, also in the case of intake ducts. This can be prevented by installing
a sound absorber.
7. The exhaust and supply ducts must be led through the roof boarding in
such a way that no condensation is formed in the roof boarding and the
whole is airtight.
8. The air intake or air outlet ducts should be laid with a slight incline to the
outside via the façade and should be wind and watertight so that no water can
penetrate from outside.
9. The intake of outside air should preferably take place on the shadow side of the
house.
10. The position of the outlet and supply of the mechanical ventilation air
and sewerage venting in relation to the supply is selected in such a way
that no nuisance occurs.

4.4.Change device orientation
When connecting the ducts, it is important to take into account where the ducts
should be placed. The connections are indicated on top of the device by icons. The
appliance is delivered as a left-hand model, which means that the ducts to and from
the house are placed on the left-hand side.
Caution: When inserting the ducts, make sure that no residual material
enters the unit, as this may damage it.
