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 appliance has four ventilation levels. The air flow rate can be adjusted for each ventilation level. The constant
volume control system ensures a balanced airflow between the supply and exhaust fan independent of the duct
pressure.
If no external control is connected to the appliance, then the appropriate ventilation level can be chosen on the
touchscreen display.
For external control a 4-way switch (®Connecting extra multiple switch with filter indication page 38) can, for
example, be chosen, but control is also possible with the Brink Air Control (®Connecting Brink Air Control page
40), CO2sensor(s) (®Connecting CO₂sensor(s) page 42), a humidity sensor (®Connecting humidity sensor
page 41) or the Brink App.
4.2 Bypass
The 100% bypass function ensures that the extract air flows past instead of through the heat exchanger, so that
cooler supply air is not heated. Particularly during summer nights it is desirable to supply 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 50) in order to adjust the operation of the bypass valve.
Automatic bypass control strategy

▪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 temperature from the dwelling is higher than 24°C (adjustable between 15°C and 35°C at step no.▪
2.2)
Bypass

▪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 appliance features a ‘Bypass boost’ function. When activated (step 2.5), the appliance is set to the highest
ventilation level as soon as the bypass opens. (adjustable at step no. 2.6).
4.3 Frost protection
To keep the heat exchanger frost-free at low outdoor temperatures, the appliance features a frost control.
Temperature sensors measure the temperatures in the appliance, when required the preheater gets activated.
The unit will also detect, very low outdoor temperatures at which the capacity of the preheater will be insufficient.
At this stage an imbalance strategy will be activated where surplus warm extract air is used.
The software ‘recognizes’ the appliance.

4.4 Optional Plus pcb
All standard appliances can be modified into a Plus version using the Plus pcb upgrade set.
The appliance equipped with this optional control board (Plus pcb) has more connections for various applications.
This extra control board can be fitted behind the existing control board on top of the appliance.
It is also possible to mount the Plus pcb with its casing on a wall near the appliance; this can be helpfull in
circumstances such as a poor WiFi signal.

5 Installation
5.1 Installation general
Installing the appliance:
1. Placing the appliance (®Placing the appliance page 13 )1.
2. Connecting the air ducts (®Connecting air ducts page 14)2.
3. Electrical connections (®Electrical connections page 15)3.
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▪
▪Any additional regulations of the local power companies▪
▪The installation regulations of the Flair 325 Enthalpy 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 Enthalpy 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 170 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 ▪
▪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). ▪
▪In order to prevent condensation on the outside of the appliance, the installation room must be ventilated. ▪
▪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.
Flair 325 Enthalpy 615921-E Brink / 13

5.3 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 in the ducts must be limited to the following maximum values:
Type of ducts Maximum Air Speed [m/s]
Collecve duct 5
Main duct 4
Duct branch: supply 3
Duct branch: outlet 3,5
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 Climate Systems B.V. 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.
Important!
When installing and maintaining the unit (see ®Maintenance installer page 29 ), check that no
dust or dirt has accumulated on the preheater! Clean the preheater well during maintenance.

5.4.3 Connecting an eBus accessory
For connecting an eBus accessory, use the, the 2-pole detachable (green) connector X17 located at the rear of the
display cover (®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 40). This connector is polarity sensitive. The connection
will not work if the wires are connected to the wrong screw terminals! The optional CO2sensor(s) or an extra
eBus preheater or postheater (®Electrical diagram page 33) can also be connected onto the eBus connector.
5.4.4 24 volt connection
The appliance features two, (black) 24 volt outputs (X16 & X18) which can be used to power accessories.
Connector X-16 is for 24 volt connection of the optional Plus pcb. The maximum power is 5 VA per output.
5.4.5 Connecting humidity sensor
The optional humidity sensor has to be connected onto the the X07 connection of the basic pcb. Use the cable
supplied with the humidity sensor. In order to connect the humidity sensor, the cover above the control has to be
removed., after which the X07 connection is accessible.
For connecting the humidity sensor, see ®Connecting humidity sensor page 41.
5.4.6 Connection internal Bus
The Modbus/ internal bus (red) connector X15 can for example be used for coupling appliances (®Coupling
appliances using internal Bus page 17).
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.
5.4.7 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.
5.4.8 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 33)for the right connection.
For the correct setting of the jumpers X12, X121 & X122 see the explanation given with electrical diagram (®

5.4.9 Coupling appliances using internal Bus
Important
Because of polarity sensitivity, always connect the internal 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 internal Bus cables is longer than 10 m, then use a
twistedpair cable for connection X15-2 & X15-3 (a twisted pair cable is also preferred with
shorter lengths)!
For M (master):
Step no. 8.1 - Master
Step no. 14.1 - internal Bus
For S1 (Slave 1):
Step no. 8.1 - Slave
Step no. 14.1 - internal Bus
For S2 (Slave 2):
Step no. 8.1 - Slave
Step no. 14.1 - internal Bus
A = Multiple switch
B = 3-pole connector red
C = Modular cable
D = 3-core low voltage cable
M = Master appliance (For example a Flair appliance type 4-0)
S1 / S2 = Slave appliances (For example a Flair appliance type 4-0); connect max. of 10 appliances via internal
Bus.
All Flair 325 Enthalpy appliances have the same air flow rate as the appliance that is set as "Master".
The fault messages of all appliances are shown on the display of the master appliance and shown on the display
of the relevant appliance.
When using a Brink Air Control or the BrinkHome, always connect this to the Master.
After connecting the cables configure each Flair 325 Enthalpy appliance:
- Enable "internalBus" in menu 14.1 "Type of Bus connection" where shortly after the network symbol appears.
- Configure each slave in menu 8.1 "Appliance setting slave 1, slave 2 etc where shortly after the M symbol
appears on the master appliance and S1, S2 symbol on slave appliances
- Power down and up all appliances.
Note: Any accessory such as moisture sensor, position switch, extension board or any eBus device must be
connected to the Flair 325 Enthalpy master appliance only.
