Where can you use this room fan?

• The room ventilator is designed to exchange air in apartments, detached houses, hotels, cafes and other domestic and public buildings. The room ventilator is equipped with a ceramic heat exchanger and a fan that both supplies fresh air and extracts air with energy recovery.
• The fan is designed for through-wall installation. The supplied wall bushing allows installation in walls up to 270 mm thick. Using the extension pipe (optional accessory), the wall can be up to 700 mm thick.
• The ventilator is designed for continuous operation.
• The air must not contain flammable or explosive substances, chemical vapors, coarse dust, soot and oil particles, sticky substances, fibrous materials, pathogens or other harmful substances.

To prevent dust from settling and accumulating in the room, the room fan must not be installed in places where the air duct may be blocked by blinds, curtains, drapes and other elements. Blocking elements can prevent normal air flow in the room, resulting in reduced efficiency.

Read this before installing the room fan

• This room fan is designed for indoor use with an ambient temperature between – 20 °C and +50 °C and a relative humidity below 80%.
• This room fan is classified as a Class II electrical appliance with an (IP) rating of IPX4.
• The product design is constantly being improved, and some models may therefore differ slightly from the models described in this manual.
• The room ventilator consists of a telescopic air duct with adjustable length regulated by the position of the inner air duct inside the outer air duct, the ventilation unit and the ventilation hood.
• The fine filter, pre-filter and ceramic energy regenerator are located inside the inner duct. The filters are designed to clean the supply air and prevent foreign objects from entering the regenerator and fan.
• The ceramic heat exchanger extracts energy from the exhaust air to heat or cool the supply air.
• The heat exchanger is equipped with a pull cord on the inside to make it easier to pull it out of the room ventilator. The heat exchanger is installed on an insulating material that also serves as a sealant.
• The room fan can be installed from inside the room it is to be installed in.

Installation

For best possible performance, we recommend that the indoor unit is mounted with a minimum distance of 15 cm from the outer edge of the indoor unit to the wall/ceiling.

1. Drill the hole

Drill a Ø160 – 170 mm round hole horizontally through the entire wall.

Tip! Use a core drill, or a drill with a hole saw and extension.

2. Install the rubber boot

Thread the included rubber sleeve over the PVC pipe, so that it seals between the plastic in the wall and the pipe.

3. Fix the pipe to the wall

Then push the pipe with the rubber sleeve into the wall. Adjust it so that it fits the wall and is perfectly straight. Use construction foam, acrylic or glue to attach the pipe evenly so that it is flush with the inside wall.

Let the fixing material dry.

4. Adjust the mounting plate

Thread the core loosely into the mounting plate for the indoor unit, and then insert the core with the mounting plate into the pipe as one piece. The connection plugs should face downwards.

5. Screw the mounting plate in place

Use a spirit level when attaching the mounting plate.

Important! Pull the core out slightly, and make sure that the core is not in tension with the mounting plate. The core must be removed for maintenance and must be loose.

6. Connect the indoor unit to the core

Hold the indoor unit while connecting the connectors together.

Tip! Rotate the indoor unit a few times clockwise to twist the wires. This will help them stay in place more easily.

8. Place the wires in the groove

Make sure that the wires are inserted well into the groove on the indoor unit and that they do not protrude to the outside. This may cause a slippage between the indoor unit and the mounting plate.

9. Attach the bottom of the indoor unit to the mounting plate

Make sure the bottom of the indoor unit is pushed against the walls. This ensures that the wires do not fall out of the groove and get pinched.

10. Attach the magnets on top

Then press the top of the indoor unit against the magnets.

The indoor unit has two holes that pass over the magnets on top of the mounting plate. These ensure that the indoor unit is in place.

Operating modes

Supply mode (“Supply”) or exhaust mode (“Exhaust”). The room fan operates in exhaust or supply mode at the selected set speed. This also applies to both master and slave if two Single Room Ventilators are paired together.

Ventilation mode (“Heat recovery”). The room fan runs for two cycles of 75 seconds each. This mode is effective in providing heat to the heat exchanger and should be used in winter to maintain good energy recovery.

When two connected ventilators are operated synchronously (master-slave connection), one room ventilator runs in supply mode and the other room ventilator runs in extract mode:

• Interval 1. The warm polluted air is extracted from the room for 75 seconds and passes through the ceramic regenerator. This gradually absorbs heat and moisture. After 75 seconds, the ventilator switches to air supply mode.
• Interval 2. The fresh and cold outdoor air passes through the heat exchanger for 75 seconds and absorbs accumulated moisture and heat. When the heat exchanger becomes cold, the ventilator switches to extract mode.

How to connect two Single Room Ventilators in series

If you want two Single Room Ventilators are going to talk to each other, you can connect them as master and slave in one series. You can have a maximum of two units per series. This way you can control so that one Single Room Ventilator blows air into the room at the same time as the other room fan extracts air.

The maximum recommended distance between Single Room Ventilators that can be connected is 15 meters. The master can only control one slave alone. The signal can pass between max. 180 mm thick walls.

1. Activate the master device

Connect the room fan to power. In the off state, press and hold the fan speed button on the unit for 5 seconds. The blue status indicator will start flashing slowly to indicate that the room fan is entering a master-slave connection mode.

Now this room fan is set to the master role.

2. Connect to slave

Connect the room fan to power. In the off state, hold the mode button on the unit for 5 seconds. The green status indicator will start flashing slowly to indicate that the room fan unit is entering master-slave connection mode.

Now this room fan is set to the slave role.

The status light on both room fans will change to a steady blue light to indicate that the master-slave connection is successful. If the master-slave connection fails, the status lights on the room fans will flash for one minute and then automatically turn off.

The pairing of master and slave should be done simultaneously within a period of 1 minute. The room ventilators should be as close to each other as possible so that they automatically find each other.

How to disable two Single Room Ventilators in series

Connect both room fans to power. In the off state, press and hold the fan speed button on the linked device for 5 seconds. The device's blue status indicator flashes slowly, and at this time, the linked device enters the master-slave connection mode. This process should be performed simultaneously on both devices for a limited time (within 1 minute). When the status indicators turn off, the devices are not connected to each other. At this stage, the devices are reset and they are zeroed without any role definition

Master/slave device control

• Without having set a master/slave role, one remote control can control one or more devices.
• After master/slave connection, the current use of the remote control can only control the master, and the master will send synchronization signals to the slave (the slave does not receive the remote control signal), so that the slave's mode is synchronized with the master's mode.
• In ventilation mode, the operating direction of the slave is the opposite of the operating direction of the master. In other modes, the direction of the slave is the same as the direction of the master.

When two Single Room Ventilators are connected, they will function as one installation. In the app, they will only appear as one Single Room Ventilator with series connection indicator activated.

Maintenance

The heat exchanger must be cleaned regularly to ensure the best possible heat recovery.

Detach the indoor unit from the mounting plate, and disconnect the wires of the indoor unit from the core. Remove the indoor unit and pull the core out from the wall. Carefully pull the small ropes on both sides of the ceramic heat exchanger and fine filter, and take the fine filter and heat exchanger out from the core.
