2.1 Glossary

The ComfoAir features:

• Balanced ventilation;

• Heat recovery;

• Bypass for free cooling;

• Frost protection;

• Open fire programme;

• Wireless (RF) control (optional)

• Non-powered extractor hood (optional)

• Preheater element (optional);

• Analogue input (0-10V);

• Enthalpy (optional).

A concise explanation of these concepts/features is given in the paragraphs below.

E

D

2.1.1 Balanced ventilation

The ComfoAir is a balanced ventilation system. Balanced ventilation means that pollutants from the kitchen, the bathroom, the toilet(s) and possibly the storage room are extracted, while the same amount of fresh air is blown into the living room and bedrooms. Gaps under or near the doors ensure a good through-flow in the dwelling. The air circulation is in balance.

2.1.2 Heat recovery

Besides ensuring a healthy balance between incoming and outgoing air, the ComfoAir also provides the benefits of heat recovery. Heat recovery means that heat from the extracted air is transferred to the fresh, and usually colder, air from outside the building.

2.1.3 Bypass for free cooling

The bypass is often used during hot days in the summer season. By allowing colder outside air in at night, the indoor temperature of the dwelling can be kept low during hot days. The bypass works automatically: simply set the required comfort temperature.

Ensure that these gaps are never obstructed by draught excluders or deep-pile carpet, for example. Otherwise the system will not function optimally.

A balanced ventilation system consists of:

• ComfoAir (A);

• Duct system for the supply of outdoor air (B) and the exhaust of indoor air (C);

• Supply valves in the living room and bedrooms (D);

• Exhaust valves in the kitchen, bathroom, the toilet and (if present) the storage room (E);

• Optional non-powered extractor hood with 3-position switch (F).

2.1.4 Frost protection

The ComfoAir is also fitted with a frost protection device.

This is an automatic protective system that temporarily reduces (or even briefly stops) the supply of outdoor air to the ComfoAir if there is a risk of freezing in the ComfoAir.

This can occur in the event of moderate to sharp frost during the winter months.

2.1.5 Open fire programme

The ComfoAir is fitted with an Open fire programme. The

Open fire programme is used in houses that have a fireplace, as there is a risk of air being sucked back from the chimney. The Open fire programme works automatically but requires activation by the installer.

While the Open fire programme is activated the supply and exhaust fan can not be turned off manually.

2.1.6 Wireless (RF) control (optional)

It is possible to set the ventilation positions of the ComfoAir with one or more wireless switches. To do this the

ComfoAir needs a build in RF module or a connected CC

Ease panel.

3 - EN

2.1.7 Non-powered extractor hood (optional)

It is possible to fit the ventilation system with a nonpowered extractor hood.

A powered extractor hood may nevery be connected to the same ducting as the ComfoAir.

The non-powered extractor hood is mounted above the hob and removes undesirable cooking smells.

There are four types of non-powered extractor hoods available:

• Type 1 g Mechanical on/off switch.

- The exhaust valve is operated by turning the on/off switch.

- The ventilation setting must be set with the ComfoAir switch;

• Type 2 g Electrical on/off switch.

- The exhaust valve is operated by pushing the on/off switch.

- The ventilation setting must be set with the ComfoAir switch;

• Type 3 g Electrical on/off switch with connection to the ComfoAir.

- The exhaust valve is operated by pushing the on/off switch.

- The ventilation setting switches automatically to an "High" setting;

• Type 4 g 3-position switch with connection to the

ComfoAir.

- The exhaust valve is operated by selecting a ventilation setting on the extractor hood.

- The ventilation setting switches automatically to an "High" setting.

The ComfoAir is not equipped with an connection for a type 3 or 4 extractor hood.

2.2 Available operating elements

The ComfoAir is fitted with the following operating elements:

• Display on the unit;

• 3-position switch;

• 3-position switch with malfunction indicator;

• Wireless 3-position switch;

• Wireless 3-position switch with malfunction indicator;

• 3-position switch on the non-powered extractor hood;

• Bathroom switch to temporarily select the highest ventilation position;

• CO

2

sensor;

• CC Ease panel.

A concise explanation of these operating elements is given in the paragraphs below.

2.2.1 Display on the unit

The ComfoAir can be operated by means of a digital display which is mounted on the unit.

The non-powered extractor hood is part of the ducting of the ventilation system, and does not form part of the ComfoAir.

2.1.8 Preheater element (optional)

Fitting the optional Preheater element in the ComfoAir gives the added bonus that balanced ventilation remains intact for longer. In that case, the supply of cold outside air no longer needs to be reduced (so soon). The Preheater element is activated and deactivated automatically.

2.1.10 Enthalpy (optional)

It is possible to fit the ComfoAir with an enthalpy exchanger. An enthalpy exchanger helps to regulate humidity levels in the dwelling. In addition to heat recovery, the enthalpy exchanger also ensures moisture recovery. Moisture recovery means that moisture from extracted air is transferred to the supply air sourced from outside the dwelling. An enthalpy exchanger is also less sensitive to freezing.

2.1.11 Analogue input (0-10V)

The ComfoAir Luxe is fitted with one input (0-10V). This input can be used to connect a sensor or control system to the ComfoAir. Examples of the options include:

• CO2 sensor; flow regulation using carbon dioxide levels;

• Moisture sensor; flow regulation using moisture levels.

If multiple position switches are available in the house, the ComfoAir will switch to the highest ventilation setting unless overruled by an automated software programme.

The display can not be used for setting the ventilation positions of the ComfoAir. The arrow keys are only for setting the additional programmes.

2.2.2 3-position switch

A 3-position switch can be used to set the ventilation positions of the ComfoAir. One or multiple 3-position switches can be fitted in the house (e.g. in the kitchen).

The following types of switches can be used:

• Type 1 g Standard 3-position switch;

• Type 2 g 3-position switch with malfunction and filter alerts indicator;

• Type 3 g Wireless 3-position switch (RF)

• Type 4 g Wireless 3-position switch (RF) with malfunction and filter alerts indicator;

• Type 5 g 3-position switch integrated on a motor free extractor hood.

2.2.3 Bathroom switch

A bathroom switch can be used to temporarily set the

ComfoAir in the highest ventilation level. This switch is mostly fitted in the bathroom to extract any excess moisture after showering, as soon as possible. The bathroom switches vary widely in model and are therefore not illustrated here. If required, the bathroom switch can be turned on and off using a time delay entered via a digital operating device.

delay timer

This ensures that the ComfoAir does not switch on at the highest setting when activated, but first waits for the delay timer to run its course.

If the bathroom switch is deactivated during the delay timer period, then the ComfoAir will remain at its current ventilation setting and not switch to the highest setting.

A wireless 3-position switch need to be retuned to the ComfoAir if a General Reset is given.

Type 1 Type 2 Type 4

overrun timer

This ensures that the ComfoAir does not switch back to the normal (or previous) setting when deactivated, but first waits for the overrun timer to run its course. Once the programmed overrun timer is complete, the ComfoAir returns to the normal (or previous) ventilation setting.

Setting the ventilation using

3-position switch(es)

A 3-position switch can be used to set 3 different ventilation positions.

Low.

- Use for low ventilation levels.

Normal.

- Use when present and no extra ventilation is needed.

• Position 3 

High.

- Use during cooking, showering and when additional ventilation is needed.

Temporary High

- Use during cooking, showering and when additional ventilation is needed for a short time.

The wireless 3-position switches have an seperated button for the Timer. After the timer delay the ComfoAir will return to the ventilation setting which was active before the timer function was activated.

If the bathroom switch is turned off within the programmed delay timer period, then the overrun function will be terminated.

Light switch

The functions of the bathroom switch can also be integrated into a light switch.

To use the Timer function with a wired 3-position switch choose setting 3 and immediately return to the setting you want after the timer delay.

The CC Ease panel has an integrated type 2 3-position switch. Next to the standard 3 ventilation settings the

CC Ease panel also has an additional ventilation setting:

5 - EN

2.2.4 CO

2

sensor

The ComfoAir Luxe can also be operated using a CO2 sensor. A CO2 sensor measures the CO2 levels in the room where it is placed. When the CO2 sensor is set on

'automatic' the CO2 sensor will control the ventilation setting according to the ventilation need in the room.

When the CO2 levels are high the ventilation setting will automatically increase. When the CO2 levels are low the ventilation setting will automatically decrease. It is also possible to use the CO2 sensor as a standard 3-position switch. The CO2 levels in the room will then by ignored.

2.2.5 CC Ease panel

The ComfoAir Luxe can be operated by means of a CC

Ease panel, which can be ordered separately.

The CC (Comfort Control) Ease panel is a digital operating device which can be mounted on the wall in the living room and from there communicates with the ComfoAir.

2.4 Maintenance by the user

The following maintenance must be carry out by the user:

• Cleaning or replacing the filters;

• Cleaning the valves (in the dwelling).

A concise explanation of these maintenance activities is given in the paragraphs below.

Failure to carry out (periodic) maintenance on the ComfoAir ultimately compromises the performance of the ventilation system.

4. Remove the old filters (B) from the

ComfoAir

B

2.4.1 Replacing the filters

If so indicated on the digital operating device, you must replace the filters.

Replace the filters (at least) once every six months.

5. Slide the new filters back into the ComfoAir.

6. Refit the filter caps (A) to the ComfoAir.

7. Reconnect the power to the ComfoAir.

When using the ComfoAir for the first time, it is recommended to replace the filters and clean the valves first. During the construction phase the ventilation system could have become dirty with building dust.

2.4.2 Cleaning the valves (in your dwelling)

The ventilation system may be fitted with the following valves:

• On the display the message “FiL” and ”tEr” will appear alternately.

• On the CC Ease panel "FilterI" will appear.

1. Press “ OK ” on the display or press " " on the

CC Ease panel until the filter warning disappears.

2. Disconnect the power from the ComfoAir.

3. Remove the filter caps (A) from the ComfoAir.

You must clean the valves (at least) twice a year:

1. Mark the setting of the valve;

2. Remove the valve from the wall or ceiling;

3. Clean the valve in a solution of soap and warm water;

4. Rinse the valve thoroughly and wipe dry;

5. Place the valve back WITH EXACTLY THE SAME

SETTING (and IN THE SAME HOLE);

6. Repeat this procedure for the other valves.

About the valve settings...

The ventilation air is supplied and discharged by means of valves. Gaps near doors in the dwelling ensure that the air flows in the right direction. In order to ensure that the correct ventilation volumes are maintained in the rooms, the following must be observed:

•

do not seal the gaps;

•

do not change the settings of the valves;

•

do not replace the valves with one another.

The installer will have set all the valves to ensure the optimum performance of the ventilation system. Therefore, do not change the setting of the valves.

13 - EN

After cleaning, make sure that all valves are placed back with the same setting (and in exactly the same ventilation hole in the wall or ceiling) AT ALL TIMES. Otherwise, system performance will be compromised.

2.5.3 What to do in the event of a malfunction

In the event of a malfunction, contact the installer. Note down the malfunction code that appears on the digital operating device. Make a note of your ComfoAir type.

This is given on the identification plate on the side of the

ComfoAir. The system should not be disconnected from the power supply, unless the ComfoAir must be taken out of service due to a serious malfunction, or for filter cleaning/replacement or any other compelling reasons.

2.5 Malfunctions

Malfunctions in the ComfoAir are reported as follows:

• The malfunction alert appears on the display,

• The malfunction alert appears on the CC Ease panel;

• The malfunction indicator on the 3-position switch lights up.

A concise explanation of methods of reporting malfunctions is given in the paragraphs below.

If the ComfoAir is disconnected from the power supply, mechanical ventilation of the dwelling will cease. This can lead to a build-up of moisture and results in problems with mould. Longterm deactivation of the ComfoAir must therefore be prevented.

2.5.1 Malfunction alerts on the digital operating device

In the event of a malfunction, the corresponding malfunction code will be displayed on the digital operating device of the ComfoAir. Please refer to the malfunction overview to find out the meaning of the relevant malfunction alert.

If the ComfoAir is installed in an area with a higher average humidity (such as bathroom or toilet) the probability of condensation on the outside of the ComfoAir is high. This is a normal phenomenon, similar to condensation on a window, on which no action is needed.

2.5.2 3-position switch with malfunction indicators

The 3-position switches that are fitted with a malfunction indicator show when a malfunction or filter dirty alert has occurred. Depending on the type of the 3-position switch, this is done in one of the following two ways:

• 3-position switch with malfunction indicator.

In the event of a malfunction or filter dirty alert the indicator lights up;

• Wireless 3-position switch with malfunction indicator.

The malfunction indicators will light up once this

3-position switch is used. One indicator will light up green to indicate communication has been established. Subsequently, in the event of a malfunctionor filter dirty alert both indicators will flash red 3 times.

After that, both indicators will light up green once more.

2.6 End of useful life

Consult with the supplier about what should be done with the ComfoAir at the end of its useful life. If the

ComfoAir cannot be returned to the supplier, avoid disposing of it with the domestic waste, and ask your local council about the options for recycling the components or processing the materials in an environmentally friendly manner.

Furthermore, do

not dispose of batteries from the wireless (RF) switches with the normal waste, but bring them to the specially designated disposal locations.
