INSTALLATION AND INITIAL CONFIGURATION

The device can be installed on the wall or to cover the 3-module flush-mounting box (type 503).
We recommend positioning at a height of 1.5 meters from the floor, in an area that respects as 
much as possible the average temperature conditions of the entire environment. Make sure that the 
distance between the router and the device is such as to guarantee stable communication.
Avoid installation near doors or windows, in niches, behind doors and curtains or in positions with 
excess or total lack of ventilation, to avoid that the reading of the temperature measured by the probe 
is in some way offset.

 

1) Install and connect the device according to the connection diagrams shown in this manual

 

2) Install and start the “Clima Wi-Fi Vemer” app on your smartphone (or tablet). Create a Vemer account with which to associate the device Tuo Wi-Fi (If you already have a Vemer account, go to step 3).

 

    a. Choose “Register” and fill in the “e-mail” and “password” fields and confirm by choosing “Register”.

 

        For security reasons it is recommended to choose a password different from the one used to access your e-mail box

 

    b. Check your e-mail box: confirm the activation of the account by clicking on the link contained in the e-mail sent by the system

 

3) Enter the e-mail address and password of your Vemer account

 

4) Add Tuo Wi-Fi to your Vemer account

 

• On the app...  Choose “

New Thermostat

” and follow the  guided procedure.

   Enter a name that identifies Tuo Wi-Fi, the pin (4 digits shown on the display of Tuo Wi-Fi) and choose an icon that helps identify the device among those proposed. Confirm with “Save”.

 

   The configuration procedure is finished. At this point:

 

•  the app displays the list of devices associated with your account among which also the newly associated device must appear.
