3.3 Guarantee
With the acquisition of a Hoval unit, you also obtain
comprehensive warranty cover under the Hoval terms
of warranty. This warranty is, however, dependent on ob-
servance of the operating instructions and on complian-
ce with the applicable legal regulations. Non-compliance
with the above will invalidate all liability and warranty
claims against Hoval.

Energy recovery
The built-in enthalpy recovery unit withdraws energy
from the extract air and transfers it to the supply air.
This enables the intelligent (temperature) and the latent
(humidity) energy to be transferred. The transmission
performance is regulated between 0 and 100%
depending on the outdoor temperature.
The advantages of the enthalpy recovery unit are:
IMPORTANT INFORMATION AND TECHNICAL INFORMATION
•
Temperature efficiency up to 90%
•
Degree of humidity recovery up to 95%
• Transmission performance can be adjusted
continuously
• No preheating required (down to -20°C)
• No condensation
• No bypass required
Air filtration
The fresh air goes through two cleaning stages,
ensuring the highest standard. A fine-meshed prefilter
(washable) at the entry of the unit prevents insects, lea-
ves, etc. from reaching the unit. Before the fresh air lea-
ves the unit, it flows through a high-capacity fine pollen
filter (ePM
1.0
50%). In addition, an activated carbon filter
can be installed on the supply air side (optional). The
operator receives a message when it is time to change
the filter.
Air delievery
Two backward-curved centrifugal fans with EC direct
current motors deliver the air. The rotating wheel made
of high-tech composite material is produced in one
piece with optimised fluid mechanics, and ensures quiet
operation of the unit. The electronics built into the motor
enable the air volumes to be finely regulated.
Fan failure:
If a fan fails - supply and/or extract air -
the unit switches off. The state is displa
-
yed on the operator terminal. Contact the
HomeVent specialist near you.
Suitability for winter
Due to the built-in enthalpy recovery unit, no condensate
is formed in the unit. Ice formation is not possible. No
preheating (electric air heater) is necessary for outdoor
temperatures down to -20 °C. The air volume ratio
between the supply air and extract air is not changed.
Summer operation
The energy recovery is reduced to a minimum according
to the outdoor temperature. This enables night cooling
(free cooling) in the summer as well as when the sea-
sons change. It is not necessary to arrange for a bypass
via dampers and a drive. In addition, the CoolVent opti-
on can actively recover cold in
air-conditioned buildings. The hot fresh air is cooled and
if necessary dried with the air-conditioned extract air.
Installation
The HomeVent
®
comfort ventilation unit is characterised
by a compact design. Different air connections are pos
-
sible using the three variable acoustic insulating boxes.
No condensate accrues in the unit.
