4.12. Remote control installation The remote-control panel is designed to be mounted in a dry indoor area by fixing it to the wall. It cannot be used in areas where water vapor condensation is present. The installation of the control panel must be carried out following the instructions provided below. Remove the mounting frame from the back panel of the housing. To remove the frame, use a flat screwdriver. The cable connecting the panel to the controller must be routed into the wall. The cable cannot be laid together with the building’s electrical network cables. The cable must not run alongside devices emitting strong electromagnetic fields.
To uninstall, press here
After the unit is connected to the power supply, LED diodes will start blinking sequentially, indicating that the controller’s software is being loaded. Loading takes about 10 seconds. If this time is much longer, check the correctness of the D + and D- wires of the transmission cable connecting the panel with the controller.

Meaning
Reducing ventilation power when leaving the house. Activation can be done with a key light switch or by activating a security alarm. Increase in ventilation capacity based on readings from connected additional CO2 or humidity sensors. Emergency shutdown of the unit in the event of a fire alarm.

An additional RJ45 adapter should be used for more convenient connection:

To activate the function, only a passive electrical switch or relay output should be used. Devices for activating functions

5. DEVICE INITIALIZATION, INSPECTION, AND OPERATION
Before turning the device on, check the inside for any foreign objects, rubbish, or tools. Make sure that the unit has an air filter, the condensate drainage (if required) is connected, and the siphon is filled with water. Inspect the air duct system to ensure there are no obstructions, such as fully closed diffusers or control valves, and make sure the outdoor supply air grilles are not blocked.
The ventilation unit may come with one of two control panels:
1) Wired Easy control panel with touch-sensitive buttons that can be used only for basic ventilation modes and settings.
2) Wired LCD SimpleTouch control panel with a touch-sensitive color display, where many of the unit’s functions and settings can be viewed and changed.
The unit can be controlled in the following ways:
1) Wired remote control Easy or LCD SimpleTouch control panel, 2) smartphone via OXYGEN Installer app (Bluetooth) or the OXYGEN easy app (Wi-Fi connection). 3) Computer via easy.oxygenvent.com website.

5.1. Operating via the control panel
The Easy control panel can only control basic ventilation modes and settings. The device is controlled by touching the selected function button on the Easy control panel. Button symbols and LED signal meanings:
– an LED that lights up means the device is switched on. Other LEDs, also indicate the status of the unit when it is switched on, e.g. fan speed selected, automatic control activated, scheduling, manual control.
– An LED illuminates to inform you when the unit is operating according to the timetable set by the weekly operating modes. If the time schedule is not set or not activated, the LED flashes. When the weekly operating mode is activated, the LED for the manual control switches off and vice versa.
– The speed of the recuperator fans will change automatically depending on the air quality information received from the CO2 sensor (if fitted).
– the recuperator operates in manual mode, which allows you to set the desired fan speed.
– increasing or decreasing the fan speed. This function only works when the manual control is activated.
– signaling of active events from the unit.
– A rapidly flashing symbol means that a Bluetooth signal is being emitted. – A steady lit symbol means there is an active connection to the Wi-Fi network and the internet. – A slow flashing symbol means there is a connection to a Wi-Fi network but no internet connection.
When the unit is plugged into the main power supply, for the first 40 seconds after switch-on, the unit automation will evaluate the factory settings, check the automation components, open the external air dampers (in case of a ductwork system with actuated dampers) and set the By-pass damper to its initial position. A low humming noise will be heard during the bypass damper setting. This is normal unit operation.
A rapidly flashing symbol means that a BT signal is being emitted. When the By-pass damper stepper motor stops running, switch the unit on by pressing the button marked with the symbol . The LED on this button will briefly illuminate, followed by the manual mode LED .
When the button marked with + is touched, the first LED will light up, and after 20 seconds, the fans will start
operating. Later, after turning off the device from the power supply and turning it on again, the device will start operating in the last set ventilation mode.

5.2. Controlling the device via “OXYGEN Installer” app (Bluetooth connection)
OXYGEN Installer app is designed for device control and configuration via Bluetooth when there is no Wi-Fi connection. Note: effective Bluetooth (BT) range is about 10 meters, so if you are in a different room from the device, your smartphone may not detect the device.
To control the device via Bluetooth, you need to install the OXYGEN Installer app on your smartphone or tablet. You can download it for free from Google Play (for Android devices from version 8 onwards) or the App Store, using the QR code or link provided on the manufacturer’s website below.

App Store

Android: https://play.google.com/store/apps/details?id=com.oxygen.lt.oxygeninstaller iOS: https://apps.apple.com/be/developer/oxygen-group-uab/id1522780335

After installing the app, open it and initiate the search. The device must be connected to the network, and Bluetooth

connection must be active

(rapidly blinking BT symbol on the control panel). In the popup window “Device

choice”, select “Internet gateway”, then proceed to “Internet gateway settings” > “Time synchronization with

phone”. The controller will automatically synchronize the date and time with your phone’s clock.

Then return to the “Select device” window and choose “Ventilator controller” (highlighted in red). In this window, you can access one of the three suggested menus: 1) User settings, 2) Service settings, and 3) Creating weekly schedules (Schedule).
