Living

Kitchen
Supply air
Fresh air
Extract air
Exhaust air
The HomeVent®draws off spent air from the rooms
and conveys fresh air into the house. The rotary
heat exchanger transfers the heat energy from the
extract air to the incoming supply air in a controlled
manner. This recovers valuable heating energy
which is lost if you ventilate by opening windows. If
required, the HomeVent®can also recover the
moisture in the extract air. This means that fresh
supply air in the desired quantity, prewarmed and if
requiredhumidied,owsintotherooms.Freshair
freedfrompollenanddustowsthroughthehouse
from the bedrooms and living areas and is drawn
off via the kitchen and sanitary rooms. The spent
air and any unpleasant odours are routed directly
into the open via the exhaust air duct.

6│Putting your comfort ventilation system to optimum use
This manual contains information on how to make optimum use of your HomeVent®comfort ventilation unit.
A correctly serviced comfort ventilation unit means optimum comfort for you and also saves you money.
Opening the windows
At night
With a comfort ventilation system, you can open the windows at any time. However, if they remain open
fortoolong(e.g.ifyousleepwiththewindowsopen)andtheoutsidetemperatureislow,theheatrecove-
ryefciencyisgreatlyreduced.
But when outside temperatures are very high, it can be a good idea to make use of the cooler night air by
openingdoorsandwindowstoallowtheairtoowintotherooms.
Summer
As a rule, you will not require heating in summer and thus no heat recovery via your HomeVent®comfort
ventilation unit. You can open doors and windows as you wish. However, bear in mind that pollen, insects
and dust can enter the house through open doors and windows.
Winter
Ifyouopenthewindowsinwinterorduringtheheatingseason,youlosethebenetsofyourHomeVent®
comfort ventilation system. Valuable energy escapes through the windows. Your comfort ventilation system
provides a constant supply of fresh air for your living area.
Your comfort ventilation unit recovers both the heat and the moisture contained in the air. In winter, the fresh
air and thus also the air in your rooms contains less moisture than in summer. The moisture which is present
is recovered via your comfort ventilation unit.
Settings on the operator terminal
The operator terminal allows you to adjust your HomeVent®comfort ventilation system to suit your needs.
This manual contains a brief description of the operator terminal. A detailed operation manual was enclosed
with your operator terminal.
Ifyouhavelostormislaidthismanual,pleasecontactyourHovalCustomerServicecentre.Youwillndthe
addresses on the last page of this manual.
Functional check
Reliable and safe functioning of the HomeVent®comfortventilationunitandoptimumefciencycanonly
be guaranteed if the unit is serviced regularly. Please also regularly check the other components of your
comfort ventilation system, such as the fresh air intake, supply and extract air ports and exhaust air grille.
Absence
Prolonged periods of absence
If you are away for a prolonged period, set your comfort ventilation to the minimum output of 15% and keep
outside doors and windows closed.
Absence in winter
Set your comfort ventilation to the minimum output of 15% and keep windows and outside doors closed.
Never switch your comfort ventilation system off completely in winter.
