4 Operation
4.1 Description
The appliance is supplied ready for plugging in and works automatically according to the standard settings. The
discharged dirty indoor air warms up the fresh clean outdoor air. That saves energy while fresh air is supplied to
the desired rooms.
The control system has four ventilation modes. The air flow rate can be adjusted for each ventilation mode. The
constant volume control system ensures that the ventilation balance between the supply and exhaust fan is
realized independent of the duct pressure.
If no external control is connected on to the appliance, then the appropriate ventilation model can be chosen on
the touchscreen display.
For external control a 4-way switch (®Connecting extra multiple switch with filter indication page 40) can, for
example, be chosen, but control is also possible with the Brink Air Control (®Connecting Brink Air Control page
42), CO2sensor(s) (®Connecting CO₂sensor(s) page 44), a humidity sensor (®Connecting humidity sensor
page 43), 2-zone demand control (®Demand-driven ventilation 2.0 page 45) of the Brink App.
4.2 Bypass
The 100% bypass makes it possible to supply outside air, which is not heated up by the heat exchanger.
Particularly during summer nights it is desirable to supply cooler outside air. The warm air in the dwelling is then
replaced as much as possible by cooler outside air.
The bypass valve opens and closes automatically when a number of conditions are met (see table below for
bypass conditions).
Follow step numbers 2.1 to 2.6 in the settings menu in the user interface, (®Setting values standard appliance
page 51) in order to adjust the operation of the bypass valve.
Bypass valve preconditions
Bypass
valve open
▪The outdoor temperature is higher than 10°C (adjustable between 7°C and 15°C at step no. 2.3) and
▪the outdoor temperature is lower than the indoor temperature of the dwelling and
▪the outdoor temperature is higher than 22°C (adjustable between 15°C and 35°C at step no. 2.2)
Bypass
valve closed
▪The outdoor temperature is lower than 10°C (adjustable between 7°C and 15°C at step no. 2.3) C or
▪the outdoor temperature is higher than the indoor temperature of the dwelling or
▪the temperature from the dwelling is lower than the set temperature at step no. 2.2 in the settings
menu minus the set temperature at the hysteresis (step no. 2.4: the factory setting for this temperature
is 20°C (22.0°C minus 2.0°C).
The appliance features a ‘Bypass boost’ function. This means that when this function is switched on (can be
switched at step 2.5) the ventilation mode with an opened bypass valve goes to maximum air flow rate (adjustable
at step no. 2.6).
Brink / 11Flair 325 615674-D

4.3 Frost protection
To prevent freezing of the heat exchanger at low outdoor temperatures, the appliance features a frost control.
Temperature sensors measure the temperatures in the appliance, when required a preheater is switched on. If in
the event of very low temperatures the preheater has insufficient capacity, stepless unbalance is created in the
appliance.
The software ‘recognizes’ the appliance.
4.4 Plus version
The ‘Plus’ version is equipped with an extra control board with more connections for various applications.
This extra control board is located in a plastic housing behind the existing control board on top of the appliance.
It is also possible to remove the entire Plus pcb including casing from the appliance and mount it on, for
example, a wall separate from the heat recovery appliance; this can be handy in certain circumstances such as a
poor WiFi signal from the Plus pcb.
A standard heat recovery appliance can also later be modified into a Plus version using the Plus pcb upgrade set.

5 Installation
5.1 Installation general
Installing the appliance:
1. Placing the appliance (®Placing the appliance page 13 )
2. Connecting the siphon and condensate discharge (®Connecting the condensate discharge page 14)
3. Connecting the air ducts (®Connecting air ducts page 15)
4. Electrical connections (®Electrical connections page 16)
The installation and installing should meet the following requirements:
▪Quality requirements of ventilation systems in homes, ISSO 61.
▪Quality requirements of balanced ventilation dwellings, ISSO 62
▪Regulations regarding the ventilation of homes and residential.
▪Safety provisions for low-voltage installations
▪The regulations for connecting indoor plumbing in homes and residential buildings.
▪Any additional regulations of the local power companies
▪The installation regulations of the Flair 325 appliance.
▪In addition to the above design and installation requirements and recommendations, the national building and
ventilation regulations must be respected.
5.2 Placing the appliance
The Flair 325 (Plus) appliance can be mounted onto the wall with the supplied mounting bracket. For a vibration-
free installation, the appliance must be mounted to a solid wall with a minimum mass of 200 kg/m2. A gypsum
block or metal stud wall does not suffice! Additional measures such as double panelling or extra studs are
required in that case. On request, a mounting support for floor mounting (with the same minimal mass) is
available.
In addition, the following aspects must be taken into account:
▪The appliance must be installed in an insulated frost-free room, in order to, for example, prevent freezing of
the condensate discharge
▪The appliance must be placed level.
▪The appliance must not be placed in a room with a high level of condensation (such as a bathroom and/or
laundry room).
▪In order to prevent condensation on the outside of the appliance, the installation room must be ventilated.
▪The installation room must be able to provide a condensate discharge with a sufficient water seal and drop for
the condensed water.
▪Newly built houses with a lot of moisture from the construction work need to be ventilated in a natural manner
before being put to use.
▪Make sure there is a free space of at least 70 cm at the front of the appliance and a free headroom of 1.8 m.
▪Make sure there is a free space of at least 25 cm above the appliance, for connecting the appliance and any
necessary servicing of the circuit board.
Brink / 13Flair 325 615674-D

5.3 Connecting the condensate discharge
The condensate discharge line for the Flair 325 appliance is located in the lower panel. The condensate is
discharged through the drainpipe. The siphon (with built-in aerator) is supplied separately with the appliance and
must be fitted by the installer below the appliance (bayonet connection). The siphon has an external connection
diameter of 32 mm. The siphon is connected to the inner sewer system. It is recommended to fit an odor trap
between the sewer system and siphon in order to avoid unpleasant odors.
Important
Never switch the two condensate discharge connections below the appliance!
It is recommended to use a 32 mm connection with gasket (HT DN32) (not supplied with the appliance) so that
the siphon can be cleaned easily in the future.
Important: During assembly always apply a lubricant, such as acid-free vaseline, to the rubber sealing ring in the
gasket. This gasket connecon has to be disconnected when servicing the appliance! The siphon must
not be glued to the condensate discharge line.
The condensate discharge can be connected, for example, with a straight or angled connection with gasket. Slide
the condensate discharge connection with gasket with sufficient length across the connection of the siphon.

Flair 325 615674-D

5.4 Connecting air ducts
All air ducts must be installed airtight. The collars on the Flair appliance are provided as standard with sealing
rings.
In order to prevent condensation on the outside of the outdoor air supply duct and the air exhaust duct from the
Flair appliance, these ducts have to be provided with an external vapor barrier as far as the appliance. If
thermally insulated piping is used here, additional insulation is not necessary.
For compliance with the maximum installation noise level of 30 dB(A), it will have to be assessed for every
installation what measures will be required to limit the noise. In order to optimally dampen the noise of the fans
from and to the dwelling through the duct, at least mufflers of no less than 1 m are required, but additional
measures may be necessary.
Prevent crosstalk through the air supply and discharge ducts by using separate branches to the diffusers. If
necessary, the supply ducts must be insulated, for instance when they are installed outside the insulated
envelope.
The outside air supply should be arranged from the shadowed side of the dwelling, preferably from the wall or an
overhang.
The discharge duct must be fed through the roof boarding in such a way that no condensation forms in the roof
boarding.
The discharge duct between the Flair appliance and the roof sleeve should be such that surface condensation is
prevented.
Always use an insulated ventilation roof sleeve.
In order to keep the noise levels down, it is recommended to restrict the external duct pressure to 100 Pa. If the
resistance of the duct system is higher than the maximum curve of the ventilator, the maximum ventilation
capacity will be lower.
The air speeds must be limited to a max. of 5 m/s in the main ducts and 3.5 m/s in the branches.
The location of the discharge of the mechanical ventilation air and the sewer stack vent must be chosen to
prevent noise nuisance.
The location of the input valves must be chosen in such a way to prevent fouling and drafts. We recommend using
Brink input valves.
When using flexible mufflers, account must be taken during the installation that these may need to be replaced
after a period of time.
Install sufficient overflow openings, door gap 2 cm.

5.5 Electrical connections
5.5.1 Connecting the power plug
The appliance can be connected to an easily accessible, earthed wall socket
with the plug that is mounted to the appliance. The electric installation must
comply with the requirements of your power company.
5.5.2 Connecting the multiple switch
The multiple switch (not supplied with the appliance) is connected to the modular connector type RJ12
(connector X14) that is placed on the rear of the display cap of the appliance (®Exploded view of appliance page
10).
For connection examples of multiple switch (®Connecting position switch page 37). A wireless remote control
(®Connecting wireless remote control (without filter indication) page 39) and a combination of multiple switches
is also possible (®Connecting extra multiple switch with filter indication page 40).
The 4-way switch can also be used to activate a 30-minutes boost mode by putting the switch to setting 3 for less
than 2 seconds and directly turning it back to setting 1 or 2. The boost mode can be reset by putting the switch to
setting 3 for longerthan 2 seconds or by switching it to absence mode ( ).
Flair 325 615674-D

There is the option of Brink demand-driven ventilation 2.0 (clock-driven or CO2-driven) (®Demand-driven
ventilation 2.0 page 45).
5.5.3 Connecting the eBus connector
For connecting an eBus connector, the 2-pole detachable (green) connector X17 is located at the rear of the
display cap (®Exploded view of appliance page 10).
The eBus protocol may for instance be used to connect the Brink Air Control (®Connecting Brink Air Control
page 42). Because of polarity sensitivity, always connect contacts correctly; the appliance will not work if these
contacts have been interchanged!
The optional CO2sensor(s) or an extra eBus preheater or postheater (®Electrical diagram page 35) can also be
connected onto the eBus connector.
5.5.4 24 volt connection
On the X16 & X18 connector of the basic pcb, 24 volt is available.
Connector X-16 is for 24 volt connection of the optional Plus pcb.
For position connection (black) connector X16 & X18 (®Electrical diagram page 35).
Maximum current reduction at plug X16 and X18 is 5 VA per connection.
5.5.5 Connecting humidity sensor
The optional humidity sensor has to be connected onto the the X07 connection of the basic pcb. For this, use the
cable supplied with the humidity sensor. In order to connect the humidity sensor, the plastic cover above the
control has to be taken off, after which the X07 connection is accessible.
For connecting the humidity sensor, see ®Connecting humidity sensor page 43.
5.5.6 BrinkBus Connection
The Modbus/ Brinkbus (red) connector X15 can for example be used for coupling appliances (®Coupling
appliances using BrinkBus page 18).
The function of this connector can be adjusted using step number 14.1 to 14.4 in the settings menu.
If the appliance is fitted with a Plus pcb, then this red connector X15 is also in use for connecting the Plus pcb;
several cables then have to be connected onto this connector X15.
5.5.7 Connecting "signal output” connector
The blue 2-pole screw connector X19. This connection is used to give a filter message or fault message.
If a filter or fault message is given in the appliance a contact is closed at connection X19. The operation of this is
set by following step number 16.1.
5.5.8 ModBus Connection
The appliance can be connected with a ModBus system such as a building management system.
Using the (red) 3-pole connector X15 (or with the Plus version the red connector X06 on the UWA2-E pcb) a
connection can be made between the appliance and the ModBus system; (®Electrical diagram page 35)for the
right connection.
For the correct setting of the jumpers X12, X121 & X122 see the explanation given with electrical diagram (®
Electrical diagram page 35); for more information and the correct modBus settings see the separate Modbus
manual on the Brink website!
Note: When ModBus is acve, the venlaon mode cannot be changed using the display or, if applicable, the connected
mulple switch! Also any connected humidity sensor will not funcon.

5.5.9 Coupling appliances using BrinkBus
Important
Because of polarity sensitivity, always connect the Brink Bus contacts X15-1 with one another,
and the contacts X15-2 and the contacts X15-3 with one another. Never connect X15-1, X15-2 or
X15-3 with one another!
Comment: If a Plus pcb has been installed; several cables would have to be connected onto the
X-15 connector.
Note: When the total length of the Brink Bus cables is longer than 10 m, then use a twisted-pair
cable for connection X15-2 & X15-3 (a twisted pair cable is also preferred with shorter lengths)!
