Important information!AirflowsThe air in the home should be changed at a continuous and sufficient rate to ensure a pleas-ant indoor climate and avoid damage to building elements caused by dampness� The ventilation unit should be stopped only while service work is in progress�

The ventilation fans are controlled from a Pre-mium control panel�

• Away = a low airflow, which can be utilized when no one is in the home and there is no need for the same ventilation that is normally in use, e�g� for moisture-removal�

• Home = normal airflow�

• Boost = a high airflow, used in connection with cooking, taking a sauna bath, showering, drying laundry and similar activities�

The Away/Home operating modes (and the supply air temperature in the electrically heated models) can be controlled with the ventilation unit’s built-in weekly timer; however the oper-ating mode can always be changed from the Premium control panel or the Premium cooker hood�

A low airflow when the home is unoccupied means economical operation� This saves on fan energy and the home heating system does not have to heat as much air during the cold season�

The most important function of the ventila-tion system is to ensure that the indoor air will be continuously fresh and to remove impurities and moisture from the air. You should therefore make an appraisal of

whether a low airflow is sufficient while the home is unoccupied. The low airflow mode must absolutely not be used when someone is in the home.

If the load on the home is greater than you’ve anticipated, then you should increase the normal airflow to a correspondingly higher rate.

Drying laundryA tumbler dryer of extract air type or a drying cabinet must not be connected to the system due to the high moisture content in the air leav-ing them� We recommend a condensing tumbler dryer without duct connection�

Freeze protectionDuring periods of cold weather, the heat ex-changer is liable to freeze if the extract air is humid� A protective function then automatically reduces the speed of the supply air fan� Under such conditions, variations in the fan speed are therefore normal�

FiltersThe ventilation unit must not be operated with-out filters� Use only filters recommended by Swegon in the ventilation unit�

CommissioningThe ventilation should not be commissioned until all work that produces large quantities of grind-ing dust or other impurities has been completed�

When the power is switched on, the ventilation unit starts up in the Home operating mode� The start time is approx� 1 minute� After that, the control panel can be used� Likewise after a power failure, the ventilation unit starts up in the Home operating mode, if the power failure has cleared the memory�

The functions of the push buttons are described in the image to the right�

Fireplace switch functionThe speed of the extract air fan decreases and the speed of the supply air fan increases for a few minutes� This produces excess pressure in the home and in this way "creates" an updraught in the chimney, which makes it easier to light the log-fire�

Selection of fan speedThe fans inside the unit can be controlled to operate at three speeds: Home/Away/Boost� Select the required fan speed from the control panel�

You can select an airflow boost time of 30, 60 or 120 minutes, or continuous boosted airflow�

The operating mode can be manually changed, even when the fan speed is controlled by the weekly timer�

Menu/Installation and serviceYou can enter settings that affect the operation and functions of the ventilation unit from the Installation and service menu and submenu� You should normally enter these settings when you install the ventilation sys-tem� The settings are described in Sections 3�5 and 3�6�

1. Installation instructions

Qualified personnel onlyThe installation work, the entering of settings and commissioning should be carried out by qualified personnel only�

Standards and requirementsThe pertinent national standards and regula-tions dealing with installation, the entering of settings and commissioning must be followed if the equipment is to operate correctly�

You will find the document entitled “Project design instructions for ventilation” at the web address www�swegon�com/casa, in which requirements on electric power, noise, airflows and duct systems are presented� Each country has specific national requirements which must be observed�

Right-hand or left-hand versionCheck whether the ventilation unit has been supplied in the right-hand or left-hand version to make certain that you are connecting the air ducts to the correct duct connection spigots on the unit� See also the dimensional drawings in Section 6, Technical data�

Drying laundryA tumbler dryer of extract air type or a drying cabinet must not be connected to the system due to the high moisture content in the air leav-ing them� We recommend a condensing tum-bler dryer without duct connection�

The covered duct connection spig-otsThe duct connection spigots of the ventilation unit must be covered by lids during transport, storage and installation�

FiltersThe ventilation unit must not be operated without filters� Use only filters recommended by Swegon in the ventilation unit�

CommissioningThe ventilation should not be commissioned until all work that produces large quantities of grinding dust or other impurities has been completed�

Important information!

1.1 General Install the ventilation unit on a base on the floor� Suit-able installation locations are machine rooms, storage spaces, etc� The temperature in the installation space must be constantly more than +10 °C� Adjust the posi-tion of the stand with the adjustable feet� Remove the heat exchanger from the ventilation unit to make it lighter for lifting� The unit should be mounted as near as possible to the wall� The space between the ventilation unit and the wall should be insulated so that the sound from the unit will not be transmitted out through the rear wall� Installation against a wall that borders on the living room or a bedroom should be avoided if possible�

1.2 Condensate dischargeConnect the condensate discharge hose to the con-densate discharge connection of the unit (3/8”, Male threads)� The condensate must be channelled to a floor drain or the like with a hose or a tube having an inner diameter of at least 12 mm� The water must not be led away directly to the sewer�

Vertically mount the water trap on the hose supplied with the unit and fill it with water� The hose must not have a second water trap or be run horizontally� The damming height of the water trap should be at least 100 mm�

1.3 Electric and control cablesThe unit has an earthed plug contact for connection to the mains power� The mains plug serves as the ventila-tion unit’s main switch and it should be connected to an electric socket at an easily accessible spot�

The room unit is equipped a 2 m long cable with plug-in contact, installed from the topside of the ventilation unit� Arrange the wall outlet at an easy-to-reach loca-tion� For power requirement particulars, see Section 6, Technical data�

Connect the ventilation unit to the Premium control panel via a modular cable� Install the Premium control panel at a place of your choice� Two modular cables are included in the supply: one approx� 3 m long cable and one 20 m long cable�

When installing the unit, make sure that you provide adequate access to the connector of each cable (loose ones as well), e�g� for servicing and adjusting the unit, if and when the need arises�

The diameter of the modular cable wiring tube should be 20 mm�

The connection of possible optional equipment is described in the wiring diagram in Section 6, Technical data� The cables for the optional items of equipment are not included in the supply�

1.4 DuctsInstall the air ducts, sound attenuators, supply air diffus-ers, air intake grilles and exhaust air ducts as shown in the ventilation drawings� To prevent the propagation of

The unit will be easier to lift into position if you first remove its plate heat exchanger.

Base

Important! If any further electrical wir-ing is required, only a qualified electrician shall be allowed to carry out this work.

The electric and control cables are located on the top side of the ventilation unit. Make sure that the electric cable can be connected to a wall outlet without ob-struction.

If you lengthen the modular cable within some building element (e.g. in a wall), you should lengthen the cable in a 20 mm dia. conduit, anticipating a possible later change of cabling.

W230.280612


sound, do not install the ducts directly against structural building elements�

Insulate the air ducts in order to reduce loss of heat or cooling energy and to prevent water from condensing on surfaces�

In general, ventilation ducts are insulated in the follow-ing manner:

• Outdoor air ducts are insulated in warm spaces and in attics that are used�

• Exhaust air ducts should always be insulated in ac-cordance with national regulations� See separate pro-ject planning instructions (for example Fire resistance classification requirements)�

• Insulate supply air ducts in cold spaces�

• Insulate extract air ducts in cold spaces�

• If the air inside the duct is colder than the air in the surroundings, the insulation should be protected by a moisture barrier (e�g� outdoor air and exhaust air in interior spaces, or chilled supply air)�

1.5 Moisture barrier against cold timber framesIt is important that the moisture barrier between cold stud work and the warm ceiling maintains its tightness at duct penetration points� A duct penetration piece (optional extra) will facilitate this� This item is available in sets of 5 for size 100, 125 and 160 mm dia� ducts� It can be fastened with tape in the moisture barrier�

We recommend the use of a mounting frame (optional extra) for sealing the moisture barrier in the attic tie beams�

Cut up the openings with approx� 10 mm smaller diameter than that of the ducts� Secure the mounting frame in the ceiling with screws through the holes on the sides� The plastic film of the moisture barrier should either be stretched and fastened between the mounting frame and the structural element of the building, or be taped tightly against the mounting frame�

N.B.! Remove the installation instruc-tions and the condensate hose from the venti-lation unit before commissioning it.

N.B.! WARNING: It is absolutely forbid-den to use the ventilation system during the period of building construction or if dust-raising work is in progress. The ducts should be covered with covers to prevent impurities from entering them.

2.1 Basic functionsHow to activate and set the functions is described in Section 3, Application.

2.1.1 Fans

The fans can be controlled to three different operating modes from the control panel�

• Away = a low airflow, which can be utilized when no one is in the home and there is no need for the same ventilation that is normally in use, e�g� for moisture-removal�

• Home = normal airflow�

• Boost = a high airflow, used in connection with cook-ing, taking a sauna bath, drying laundry and similar activities�

The Away/Home operating modes can be controlled with the ventilation unit’s weekly timer; however the op-erating mode can always be changed from the Premium control panel�

You can select the airflow boost time manually to 30, 60 or 120 minutes, or for continuous boosted airflow, from a Premium control panel�

2.1.2 Temperature

The user sets a supply air temperature of his or her choice, normally 13–20 °C� This set value is a so- called setpoint, which the ventilation unit makes an effort to reach, if conditions allow this� N�B�! In the Econo models, the setpoint can be set with a thermostat inside the ventilation unit�

A heat exchanger collects heat energy from the extract air and transfers it to the supply air� When the heating output of the heat exchanger is not enough, the follow-ing takes place:

1) The electrically heated air heater is activated and heats the air to reach the preset supply air temperature�

The air heater can be switched off from the control panel if heating is not required�

2) In the Econo models, the supply air temperature can be set on the thermostat inside the ventilation unit� You can turn the thermostat dial to the minimum setting if heating is not required�

2.1.3 Protective functions

The electric air heater has two protective functions�

• The excess temperature (thermal overload) protection switches off the heater, if the temperature exceeds 50 °C� The protection automatically resets itself when the heater has cooled down�

• The excess temperature protection switches off the heater, if the temperature exceeds 90 °C� The protec-tion must be manually reset by pressing a push but-ton on the heater�

The heat exchanger is equipped with a freeze protec-

tion� When the weather is cold, there is risk of the heat exchanger freezing� To counteract this, the controller activates the air heater and reduces the speed of the supply air fan� This protective function automatically resets itself when the temperature increases�

The fans have a thermal overload cutout, which stops them if the temperature rises too high� The controller also stops the fans if a serious malfunction occurs in the ventilation unit� When the temperature drops or the malfunction has been remedied, the protection auto-matically resets itslf in both cases�

On the Econo model’s waterborne air heater, there is a temperature sensor that protects the air heater from freezing�

•Iftheairheater’stemperaturehasdroppedtoariskylevel, the red signal lamp on the control panel will flash, but the ventilation unit will operate normally�

•Iftheairheater’stemperaturedropsfurther,thecontroller will stop the ventilation unit to prevent the air heater from freezing� The freeze protection alarm can be acknowledged from the Installation and service menu: Alarms�

2.2 Optional equipment – automated control equipmentHow to activate and set the functions is described in Section 3, Application. The connection of optional equipment is described in the wiring diagram in Section 6, Technical data.

The optional items of equipment can be used for achiev-ing the type of control required in the following way:

• Boost timer. The boosted operation mode can be switched in from a control panel or a Premium cooker hood� A separate boost timer (push button) can be installed in another place, e� g� in a dressing room, laundry room, etc�

• Humidity sensor. The ventilation unit detects if the relative humidity (RH) exceeds the preset limit value, e�g� 60 %, and switches the fans to operate in the boost mode� It can be placed in a sauna, a bathroom, a scullery, etc� The sensor voltage is 24 V DC�

• Separate fireplace switch. The function can be switched in from a control panel or a Premium cooker hood� A separate fireplace switch (push button) can be installed in another place, e� g� next to an open fireplace� The speed of the extract air fan decreases and the speed of the supply air fan increases for a few minutes� This produces excess pressure in the home and in this way "creates" an updraught in the chimney, which prevents smoke from entering the room when you light the log-fire�

• Occupant detection sensor. The sensor detects movement in the home and increases the fan speed to the Home value� This improves the operational economy if the home is nor regularly occupied�

• Carbon dioxide sensor. It is suitable for use when-

W230.280612


3. Application

3.1 To set the airflowsThe home should have continuous air change to ensure a pleasant indoor climate and avoid damage to building elements due to humidity� The ventilation unit should be stopped only while service work is in progress�

The airflows should be set according to the ventilation plan and applicable regulations� For estimated values, use the sizing curves in Section 6, Technical data� A qualified person should set the ventilation unit’s and the ventilation equipment’s airflows using appropriate meas-urement equipment�

A low airflow when the home is unoccupied means economical operation� This saves on fan energy and the home heating system does not have to heat as much air during the cold season� An assessment of whether a low airflow is sufficient for removing emissions, mois-ture, etc� from the air should be made�

3.2 Premium control panelWhen the power is switched on, the ventilation unit starts up in the Home operating mode� The start time is approx� 1 minute� After that, the control panel can be used� Likewise after a power failure, the ventilation unit starts up in the Home operating mode, if the power failure has cleared the memory�

The functions of the push buttons are described in the image�

The indicating lamp on the control panel shows the vari-ous functions of the ventilation unit in different colours�

1� Steady green glow: The ventilation unit is operating normally�

Check that the ventilation unit, filters and ducts are clean and that there are no loose objects in them before commission-ing the ventilation system.

ever the number of occupants varies� The sensor increases the fan speed to the Boost value, when a preset maximal value is exceeded, e�g� 1000 ppm�

• Negative pressure compensation. Negative pres-sure arises in the home when a separate cooker hood or central vacuum cleaner is used, since the extract airflow becomes substantially higher than the supply airflow� A separate sensor (e�g� one that senses the difference in pressure) can transmit a signal to the controller to increase the supply air flow from the ventilation unit to restore balance�

• Supervision (DDC). Certain functions can be con-trolled from the automated building management system of the building� See the connection schedule for optional items of equipment in Section 6, Techni-cal data�

• Home/Away switch. For example, systems con-trolled from a cooker hood, generally have a separate Home/Away switch (optional extra) by the front door� The switch starts the Away function in the ventilation unit� The switch can be a standard switch of optional type�

2� Flashing green glow: The freeze protection has been activated�

3� Orange flashing glow: The electric air heater has been activated�

4� Orange glow: The heat exchanger is bypassed, e�g� for summer night cooling�

5� Flashing red glow: The automated protection system has stopped the fans due to a malfunction�

6� Steady red glow: Alarm or a service reminder�

3.3 Start menu3.3.1 Fireplace switch function

The fireplace switch function decreases the extract air fan speed and increases the supply air fan speed for approx� 10 minutes� This produces excess pressure in the home and in this way "creates" an updraught in the chimney, which prevents smoke from entering the room when you light the log-fire�

An unnecessary or longterm use of the fireplace switch function in the wintertime may easily activate the frost protection function during an unnecessarily long time, which creates negative pressure in the house and smoke can be drawn into the house via the chimney� You can cancel the fireplace switch function by pressing the fireplace function button once again within 10 minutes after you pressed it the first time�

Investigate and, if necessary, increase the temperature from the menu, or on the Econo model with the ther-mostat inside the ventilation unit�

The electric air heater is faulty (electrically heated models)

The air heater has one excess temperature and one overheating protection functions� The alarm is initiated in accordance with Section 5�1�1� if either of these are activated�

The over temperature protection resets itself automati-cally when the temperature decreases� The overheating protection must be reset by pressing a push button on the air heater� If you hear a click when you press in the button, this indicates that the overheating protection has been reset�

Excessively high temperature may be due to too low an air flow through the air heater� The cause can be that a filter, outer wall grille or supply air device is clogged� Replace and clean, if needed�

Tip: In most models, the outer wall grill has an insekt net� If the net has small mesh, dust and insects can clog it� During certain conditions it it is also liable to freeze� Remove the net or replace it with a net with larger mesh�

An excessively high temperature can also be due to the supply air fan having stopped or that the temperature sensor has been shaken loose from its position in the fan intake�

Badly isolated ventilation ducts

If the unit emits warm air but the supply air discharged from the air diffuser feels cold, this may be due to poorly insulated ventilation duct�

5. Alarms and troubleshooting

Freeze protection

During periods of cold weather, the heat exchanger is liable to freeze if the extract air is humid. A protective function then automatically reduces the speed of the supply air fan. Under such conditions, variations in the fan speed are therefore normal.

The LED on a Premium control panel flashes green when the freeze protection is activated.

Faulty air heater for preheating

During the thawing period, the outdoor air is heated by the air heater for preheating, so that the thawing phase will be shorter� If the thawing phase goes on for a long time, the cause may be that the overheating protection in the air heater for preheating has tripped� The over-heating protection in the cubicle inside the ventilation unit�

For acknowledging the overheating protection

The ventilation unit does not obey commands

If two overlapping commands are issued, the unit obeys the command with the highest priority, e�g� the freeze protection�

Priority 1: Commands from outer sensor or the ventila-tion unit’s protective functions�

Priority 2: External supervision (DDC)�

Priority 3: A normal control panel or the operation of the cooker hood�

REMEDIAL MEASURES WHEN A FAULT HAS BEEN DISCOVERED

If a defect is discovered, the client must without delay report the defect to the manufacturer or to an authorized service partner� Specify which product has a fault (product model, type designation on the guarantee card or on the product identification plate, serial number); describe the type of fault as accurately as possible, and the circumstances under which the fault has arisen� If there is risk that the fault may have consequential impact on the environment, steps must be immediately taken to prevent this from occurring� A prerequisite for valid guarantee liability is that the manufac-turer or a representative of the manufacturer is given opportunity to inspect the fault reported in the guarantee claim before the repair work begins� A prerequisite for repair under guarantee is also that the client, in a satisfactory manner, can prove that the guarantee is valid (= written receipt of purchase)� After the guarantee period has expired, guarantee claims, which have not been submitted in writing prior to the expiration date of the guarantee, are not valid�
