THE CONTROL PANEL MUST BE INSTALLED BY A QUALIFIED EXPERT ONLY, PROPERLY
TRAINED AND HAVING THE REQUIRED TOOLS AND MATERIALS CHOOSING LOCATION FOR CONTROL PANEL INSTALLATION
Examples of wireless alternatives and system operation scenarios

Example 1 : direct control panel connection to master ventilator without using a router.
The control panel must be installed within the range of the Wi-Fi access point built into the master ventilator.

• Set the ventilator to Wi-Fi access point master mode (see the ventilator user’s manual).
• Install the control panel within the range of the Wi-Fi access point built into the ventilator.
• Pair the control panel with the ventilator (see below).

Note: the limitations specific to the number of devices that can be connected to the ventilator in the Wi-Fi access point mode are detailed in the ventilator user’s manual.

Example 2 : connection via a router with a single Wi-Fi access point.
The control panel can be installed outside the range of the Wi-Fi access point built into the master ventilator.

• Connect the router to the access point built into the router (see the ventilator user’s manual).
• Bring the control panel within the range of the Wi-Fi access point built into the ventilator.
• Pair the control panel with the ventilator (see below).
• Install the control panels within the range of the WiFi access point built into the ventilator.

Example 3 : connection via a router connected to several Wi-Fi access points.

• Connect the router to one of the Wi-Fi access points (see ventilator user’s manual).
• Pair the ventilator with the first group of panels.
• Connect the ventilator to the other Wi-Fi access point (see ventilator user’s manual).
• Pair the ventilator with the other group of panels.

ATTENTION: IRRESPECTIVE OF THE SELECTED CONNECTION PATTERN THE PANEL MUST BE WITHIN THE RANGE OF THE WI-Fl ACCESS POINT BUILT INTO THE VENTILATOR DURING THE PARING OF THE CONTROL PANEL WITH THE MASTER VENTILATOR.
