INTRODUCTION
INTRODUCTION
INTRODUCTION
Ventilation has to be constant for the indoor air to stay healthy for
the dwellers and the structures of the dwelling. Even for longer
holidays, it is not advisable to stop the ventilation, because the
indoor air will become stuffy and, during the heating season, the
indoor air humidity may condense in the ventilation ductwork and
structures, causing moisture damage.
You can control and automate the ventilation unit operation in the
following ways:
• By using a control panel installed in the building
• Through the Home local network connection and the Web
interface
• Through the Adroit Cloud Service and the Web interface
• Through a remote monitoring service or building automation
by using voltage signals or Modbus messages
The required ventilation may also be adjusted automatically with
the optional carbon dioxide and humidity sensors. In this case,
ventilation remains optimal even if the dwelling is unoccupied.
By using the week clock, you can create just the right ventilation for
your individual lifestyle.
The following settings will be congured during the setup of the
ventilation system:
• user interface language
• time and date
• system administrator password
• parental controls, if turned on
• fan settings
• user prole settings, such as the temperature.
The qualied ventilation installer must complete the fan settings in
accordance with the ventilation plan. Do not change these settings.
STARTING THE UNIT
If you are starting the ventilation unit for the rst time or after a
maintenance procedure, rst connect it to the mains. During the
start-up, the diagnostics display will appear for a few seconds, after
which the main display of the At home prole opens.
If the ventilation unit was turned off from the control panel (see
Turning the Unit Off), you can start it by pressing any control panel
button.
WARNING
The unit is not intended for use
by children under 8 or by persons
with reduced sensory, physical or
mental capabilities, or whose lack of
knowledge and experience do not
ensure safe operation of the unit.
Such persons can use the unit
under supervision, or by following
the instructions of someone who is
responsible for their safety.
TIP
Adroit Digital Controller automatically
switches to the sleep mode when
the Sleep time set in the display
settings has elapsed. You can wake
up the control panel by pressing any
control panel button.
NOTE
The rst starting of the unit may take a
while, because of the software version
check.

unit. Copy the update le HSWUPD.
BIN (Please note! Do not alter the le name!) you have downloaded
at the root of the control panel (the control panel will be displayed
on your computer as a mass memory or a removable disk drive).
When the le has uploaded onto the control panel, remove the USB
cable.
Next, the control panel will take a while to load the update.
The control panel will now start to load the update le onto the

FAN SETTINGS
The following sections describe how to set the output ratio between
the supply and extract air fans.
IMPORTANT
Adjust the air ows, according to the values in the ventilation
design. Try to adjust the air ows in a way that you do not have to
choke the air ows at the valves. This is the most energy efcient
set up.
First, set both supply and extract values as close to the ideal value
as possible. The ideal values are presented in the supply and
extract air volume graphs. If, at the beginning, the air ows differ
greatly from the designed rate. Check the air ows by measuring
them at the valves, and ne tune the airow rates, if necessary by
rst adjusting the units fans, then by adjusting the room valves.
NOTE
If the outside air is extremely cold (below -3°C on a plastic cell),
the ventilation device may have to defrost the heat exchanger cell.
If this occurs, you cannot adjust the air ows and the Defrosting
gure is shown on the control panel.
SUPPLY AIR
When you want to set the system supply air settings, proceed as
follows:
1. The deployment wizard Fan settings screen is opened.
2. Set the supply air quantity as a percentage of the maximum by
using the Plus and Minus buttons. The fan speed (1/min) will
change, according to the percentage value.
3. Once you have set the supply air fan settings, press the Right
arrow button.
EXTRACT AIR
When you want to set the system extract air settings, proceed as
follows:
1. The deployment wizard Fan settings screen is opened.
2. Set the extract air quantity as a percentage of the maximum
by using the Plus and Minus buttons. The fan speed (1/min)
will change, according to the percentage value.
3. Press the OK button.
4. The extract air fan speed is now set.
WARNING
The ventilation specialist has set
the supply and exhaust air settings
when deploying the ventilation
unit. If you make changes to the
settings, ensure that they conform
with the ventilation design to
ensure the system still complies
with Building Regulations.

USING THE UNIT
VENTILATION PROFILES
THE VENTILATION UNIT HAS FOUR VENTILATION PROFILES:
AT HOME
Use this ventilation
prole when the
dwelling or the
premises are
occupied
AWAY
Use this ventilation prole
when the dwelling or
premises are unoccupied,
e.g. during a trip or other
long absence.
FIREPLACE PROFILE
Use this ventilation prole when, for example,
you are making a re in the replace. This
prole is primarily used to create momentary
overpressure in the dwelling to help elevate
back spillage into the room.

Use this prole to increase
the ventilation rate, e.g. when
there are more people than
usual in the dwelling or local
ventilation regulations dictate.

•Droplet and two shaded bars — The relative humidity of air is slightly higher than normal.
Ventilation efficiency needs to be boosted. When the automatic fan speed on the relative
humidity of the air is turned on, ventilation is boosted control based automatically.
• Droplet and three shaded bars — The relative humidity of air is significantly higher than
normal. The fan speed will be automatically increased if automatic adjustment has been chosen.
CO2symbols indicate the carbon dioxide or the VOC level in the air.
