This chapter describes how to operate the ComfoAir.
2.1 Glossary
The ComfoAir features:
• Balanced
ventilation;
•
Heat recovery;
•
Bypass for free cooling;
•
Frost protection;
•
Chimney sweep programme;
• Wireless (RF) control (optional))
• 0 - 10V input;
• Pre-heater
(optional);
• Enthalpy
(optional).
A concise explanation of these concepts/features is
given in the paragraphs below.
2.1.1 Balanced ventilation
The ComfoAir is a balanced ventilation system. Bal-
anced ventilation means that pollutants from the
kitchen, the bathroom, the toilet(s) and possibly the
storage room are extracted, while the same amount
of fresh air is blown into the living room and bed-
rooms. Gaps under the doors ensure a good through-
fl ow in the dwelling. The air circulation is in balance.
Ensure that these gaps are never obstructed
by draught excluders or deep-pile carpet, for
example. Otherwise the system will not func-
tion optimally.
A balanced ventilation system consists of:
• ComfoAir 200 (A);
• Duct system for the supply of outdoor air (B) and
the exhaust of indoor air (C);
• Supply valves in the living room and bedrooms
(D);
• Exhaust valves in the kitchen, bathroom, the toi-
let and (if present) the storage room (E).
2.1.2 Heat recovery
Besides ensuring a healthy balance between incom-
ing and outgoing air, the ComfoAir also provides the
benefi ts of heat recovery. Heat recovery means that
heat from the extracted air is transferred to the fresh,
and usually colder, air from outside the building.
2.1.3 Bypass for free cooling
The bypass is often used during hot days in the sum-
mer season. By allowing colder outside air in at night,
the indoor temperature of the dwelling can be kept
low during hot days. The bypass works automatically.
All you have to do is set the required comfort tem-
perature.
2.1.4 Frost protection
The ComfoAir is also fi tted with a frost protection de-
vice. This is an automatic protective system that tem-
porarily reduces (or even briefl y stops) the supply of
outdoor air to the ComfoAir if there is a risk of freezing
in the ComfoAir. This can occur in the event of moder-
ate to sharp frost during the winter months.
2.1.5 Chimney sweep programme
The ComfoAir is fi tted with an Chimney sweep pro-
gramme. The Chimney sweep programme is used in
houses that have a fi replace, as there is a risk of air
being sucked back from the chimney. The Chimney
sweep programme works automatically but requires
activation by the installer.
While the Chimney sweep programme is ac-
tivated the supply and exhaust fan can not
be turned off manually.
2.1.6 Wireless (RF) control (optional)
It is possible to set the ventilation positions of the
ComfoAir with one or more wireless switches. To do
this the ComfoAir needs a build in RF module or a
connected CC Ease panel.
2.1.7 0-10V input
The ComfoAir Luxe has a single 0-10V input.
This input allows various different types of control
system or sensor to be connected. Examples of the
options include:
• CO
2
sensor; fl ow regulation using carbon dioxide
levels;
• Moisture
sensor;
fl ow regulation using moisture
levels;
2.1.8 Pre-heater (optional)
Fitting the optional pre-heater in the ComfoAir gives
the added bonus that balanced ventilation remains
intact for longer. In that case, the supply of cold out-
side air no longer needs to be reduced (so soon). The
pre-heater is (de)activated automatically.
2.1.9 Enthalpy (optional)
It is possible to fi t the ComfoAir with an enthalpy ex-
changer. An enthalpy exchanger helps to regulate hu-
midity levels in the dwelling. In addition to heat recov-
ery, the enthalpy exchanger also ensures moisture re-
