Congratulations, you are the owner of a
ComfoAir 160,
a heat recovery unit from Zehnder.
We wish you lots of comfort.
2.1 Glossary
The ComfoAir features:
• Balanced ventilation;
•
Heat recovery;
• Bypass for free cooling;
• Frost protection;
•
Open fi re programme;
• Wireless (RF) control (optional)
• Enthalpy (optional);
• Analogue input (0-10V).
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. Balanced
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 bedrooms. Gaps under or near
the doors ensure a good through-fl ow of air in the dwell-
ing. The air circulation is in balance.
Ensure that these gaps are never obstructed ,
for example by draught excluders or deep-pile
carpet. Otherwise the system will not function
optimally.
A balanced ventilation system consists of:
• ComfoAir (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 toilet
and (if present) the storage room (E).
2.1.2 Heat recovery
Besides ensuring a healthy balance between incoming
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 summer
season. By allowing colder outside air in at night, the in-
door temperature of the dwelling can be kept low during
hot days. The bypass works automatically: simply set the
required comfort temperature.
The bypass will always stay open for half an hour
2.1.4 Frost protection
The ComfoAir is also fi tted with a frost protection device.
This is an automatic protective system that temporarily
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 moderate to sharp frost
during the winter months.
2.1.5 Open fi re programme
The ComfoAir is fi tted with an Open fi re programme. The
Open fi re programme is used in houses that have a fi re-
place, as there is a risk of air being sucked back from the
chimney. The Open fi re programme works automatically
but requires activation by the installer.
While the Open fi re programme is activated the supply
and exhaust fan cannot be turned off manually.
2.1.6 Wireless (RF) control (optional)
It is possible to set the ventilation positions of the Com-
foAir with one or more wireless switches. To do this the
ComfoAir needs a built in RF module or a connected CC
Ease panel.
