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.
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.
The following settings will be configured during the setup of the
ventilation system:
• user interface language
• time and date
• system administrator password
• parental controls, if turned on
• fan settings
• user profile settings, such as the temperature.
The qualified ventilation installer must complete the fan settings in
accordance with the ventilation plan. Do not change these settings.

FAN SETTINGS
To set the output ratio between the supply and extract air fans:
IMPORTANT
Adjust the air flows according to the values specified in the
ventilation plan. It is recommended that the air flows be adjusted
without having to choke the air flows at the valves. This is the most
energy-efficient set up.
First, set both values as close to the ideal value as possible by
looking at the supply and extract air fan curves. If the ratio between
the air flows is very high at first, the ventilation unit may have to
carry out extra defrosting cycles in sub-zero temperatures, thus
making adjustment of the air flows more complicated. Check
the air flows by measuring them at the valves, and fine-tune the
percentage values as required.
NOTE
If the outdoor air is extremely cold (below -10°C on an aluminium
cell, the ventilation unit may have to defrost the heat recovery cell.
If this happens, the Defrosting icon will be displayed on the control
panel. The air flows cannot be adjusted during defrosting.
SUPPLY AIR
When you want to make 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 make 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 ratio is now set.
NOTE
You can browse the Fan settings by using the Right arrow button.

BEFORE BEGINNING
MAINTENANCE WORK
The safety switch automatically turns off the power when
the upper door of the unit is opened. Always disconnect
the power plug before starting the ventilation unit
maintenance.
OPENING AND CLOSING THE DOORS
1. T
urn the latches to open the upper door of the
ventilation unit.
2. Lift off the door.

Caution: the door is heavy.
3. Open the lower door of the ventilation unit by
undoing the finger screws.
4. Lift the lower door off.
5. Close the doors in reverse order.
There are two unit models, left- (L) and right-handed (R).
The figure shows the right-handed model.
FILTERS
When the maintenance reminder becomes activated,
check the cleanliness of the filters and replace them if
required.
The Adroit ventilation unit has three air filters:
• Class G4 coarse filter filters insects, heavy pollen
and other relatively large foreign objects out of the
outdoor air.
• Class F7 fine filter filters microscopic pollen and
dust particles out of the supply air.
• The coarse filter filters the extract air and keeps the
heat recovery cell clean.
The filter change interval depends on the ambient dust
concentration. It is recommended that the filters be
changed every spring and autumn, or at the very least
once a year.
TIP
Using original Airflow filters ensures that the ventilation
unit remains in top condition, giving the best results.

CONDENSING WATER
MAINTENANCE OF THE CONDENSING WATER
OUTLETS
In the heating season, the extract air humidity condenses to water.
In new buildings, condensation runoff can form rapidly. Condensed
water must be able to freely leave the unit. At some time before
the heating season begins (e.g. during autumn maintenance),
check that the condensing water outlets in the bottom pool are
not clogged and that there are no leakages. To check this, pour
some water into the pool. Clean as required. Check where the
condensing water outlets are in the Installation section.
33
NOTE
Some condensing water may
have accumulated in the bottom
pool of the unit; this is normal
and requires no corrective action.
WARNING
Water must at all times be kept out
of the electrical system.

OPERATION AND SAMPLE CONNECTION
Always follow first and foremost the connection diagram
provided by the HVAC designer or heat pump manufacturer.
The accompanying figure shows an example of the arrangement
for connecting the heating/cooling radiator unit to the heat
collection circuit.
Connect the radiator output pipe to the heat collection circuit return
pipe. Direct the fluid returning from the radiator unit to the heat
collection circuit return pipe. If you know that there is a large loss
of internal pressure inside the heat pump, the heat pump should be
bypassed. If this is done, the fluid circuit will come into operation
when the heat pump comes to a halt. When this happens the
pressure loss in the one-way bypass valve Y2 must be lower than
the pressure loss in the heat pump.
E
V
K
Circulation pump. Not included in the delivery. The
pump should be suited to pumping liquid colder than the
surrounding air, due to risk of condensation (for example,
Grundfos Magna 1 25-80).
Solenoid valve. Not included in the delivery. The valve that
is chosen must be compatible with the heat collection circuit
fluid.
Condensing water tube. Not included in the delivery.
IP De-aerator. Not included in the delivery.
S
C
Y
HEAT COLLECTION CIRCUIT
The pump starts when the outdoor
air temperature drops below the
winter limit value set at the factory
(-5 °C).
24 VDC relay/contactor for controlling the pump and the
solenoid valve. Not included in the delivery. (For example,
ABB CR-P024DC2)
One-way valve. Not included in the delivery.
Y2 One-way valve. Not included in the delivery. The pressure
loss must be less than the pressure loss of the heat pump.
40
NOTE: COOLING
The value set for the supply air
temperature of the active profile
(e.g. At home) controls the startup
of the pump. The pump starts when
the supply air setting is below the
temperature of the supply air that is
blown into the apartment.
NOTE
Due to the risk of humidity damage,
in a duct that has not been
insulated for condensation the
supply air temperature must not fall
below 16 … 20 °C.
External electrical junction box for the DV245.
NOTE: HEATING
NOTE
When selecting the relay, take
account of the maximum allowed
combined power supply (6W) of
the circuit card in the external
connection box, if the relay power is
obtained from the circuit board
+24V connector.
