SAFETY
ELECTRONIC COMPONENTS
Only the professional installer is authorised to open the ventilation unit. The installer should use the appropriate tools for each of the work.
The electronic components of the ventilation unit may be under electrical tension. In case of a defect, contact a professional installer and have repairs carried out only by competent personnel.
SAFETY INSTRUCTIONS
- This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children must be supervised to ensure that they do not play with the appliance.
- If the power cord is damaged, it must be replaced by the manufacturer, the after-sales service or persons with similar qualifications, to avoid danger.
- The user is responsible for the safe disposal of the ventilation unit at the end of its service life, in accordance with locally applicable laws or regulations. You can also dispose of the unit at a collection point for used electrical appliances.
Very important! Lethal
- The exhaust fan creates a negative pressure in the house. It is important to ensure that no flue gases from open fire, stove or other combustion appliances can be drawn into the house. It is important that a sufficiently sized outside air supply is always provided for the (open) burning appliance.
- Always consult the installer of your combustion appliance to check that there is no danger of flue gases entering the home.
- The negative pressure in the house can be limited by ensuring that window grilles are always sufficiently open.
MAINTENANCE
The ventilation unit should be inspected periodically for contamination. For inspection, the ventilation unit should be switched off by unplugging the power cord. The ventilation unit contains rotating mechanical
components. When you unplug the ventilation unit, these components continue to run for a few seconds. Therefore, wait about 20 seconds after switching off the ventilation unit so that the components are stationsry. During maintenance, always follow the instructions on page 11.
Make sure that the plug cannot be reinserted into the socket by someone else before you have finished your work. Do not plug in until the ventilation unit has been installed and all components have been fitted.
GUARANTEE
Vasco is not liable for damage caused by failure to observe the safety instructions or by failure to follow the instructions in the user manual. The warranty conditions can be found on page 13 of this manual.
MANUAL FOR THE USER
- This ventilation unit is designed to ventilate homes. The ventilation unit extracts air in the kitchen, bathroom, laundry room and toilet. This creates a negative pressure in the house, allowing fresh air to flow in through window grilles and any other openings.
- The amount of ventilation can be controlled with RF position switch, CO2 RF switch or the RH RF switch + the built-in RH stab sensor + the motion sensor.
- It is not allowed to connect a hood with motor or a dryer to the ventilation unit.
- The ventilation unit can be controlled by a linked switch. More instructions on how to link the switch can be found on page 8.
INTERNAL HUMIDITY SENSOR
Internal humidity sensor
The internal moisture sensor continuously records the moisture level at 5-second intervals. When moisture increases greater than 2%, “Internal Moisture Control” becomes active. During this “Internal Moisture Control”, the ventilation setting will be minimum “Medium”. When the humidity level has dropped again, ventilation setting “Medium” remains active for another 15minutes. The unit then returns to the original ventilation setting.
RF position switch
For the C400 ventilation units including RF switch, a coupled RF mode switch is supplied with the ventilation unit. In the middle of the switch, an LED is provided that lights up green once if the requested position is correctly com- municated.
CO2 RF switch
The ventilation unit is expandable with a CO2 RF switch that allows you to choose a fixed flow rate or a flow rate according to your needs. By touching the control area at the bottom several times, you can scroll between the different modes. The LED at the top right indicates the mode. 
RH RF switch
The ventilation unit is expandable with an RH RF switch that temporarily boosts the ventilation flow rate when you take a shower, for example. By touching several times on the control area at the bottom, you can scroll between the different modes. The LED at the top right indicates the mode. 
- (existing) wired switch
You can also control the ventilation unit via a wired switch. When the switch is operated, the ventilation unit always adjusts the flow rate instantaneously. You can still use the RF switches to switch back to a lower or higher setting. However, the mechanical switch will no longer indicate the correct setting. - Motion sensor PIR
The motion sensor detects movement close to the sensor. If motion is detected, the motion sensor communicates with the ventilation unit via wire-free communication (RF). The ventilation unit will activate ventilation mode medium. If a higher ventilation setting was already active, it will be maintained. - User interface (UI) settings
In standby mode, no LEDs are lit. If the control zone is operated for 10 seconds while the status LED is off, status LED flashes between blue and green to indicate that the menu for user interface (UI) settings can be entered. Releasing the control zone now opens the menu. - Standby user interface (UI)
The settings menu can be used to configure the time switch. When the user interface (UI) settings menu is opened, the current status of the time switch is indicated by the 5 LEDs. Each time the control zone is operated, the next position of the time switch is selected. If the control zone is not touched for at least 10 seconds, it automatically the standby user interface (UI) is activated. When the user interface (UI) menu is exited, the selected time switch position is used and saved.
The time switch can be used to switch on a lamp. For example, if status level 3 is active, the lamp will light for 60 seconds after a motion
detection.
Maintenance of ventilation unit
The user should ensure that the complete installation is periodically maintained by the installer. The installer should follow the operations described on p. 11.
Under normal operating conditions, this maintenance should take place 4 to 5 times a year. If a extractor hood is connected, this frequency should be increased depending on the degree of soiling.
Replacing batteries RH RF SWITCH
The batteries in the RH RF switch for the bathroom must be replaced periodically. To do this, remove the front panel. The 1.5 V AA batteries are now visible and can be replaced.
