 fig. 7, page 5).

If the problem persists:
▶ Press the Reset button (

 fig. 20) and hold for several seconds. 

Please note! This means that all personalised settings are deleted, 
and the Wi-Fi connection must be established again.

If the problem persists:

The fault displays for the heat source are visible on the touch screen and 
are sent automatically from the controller to the EasyControl app.

No Wi-Fi connection. The Wi-Fi signal for the Wi-Fi 
router may be too weak. Install a Wi-Fi amplifier.

The “Hide” function for the Wi-Fi router is possibly 
switched on, or the “Broadcast” function (sending 
SSID) may be switched off. Temporarily switch off the 
“Hide” function or switch on the “Broadcast” function.

No connection to the Internet server. Wait until the 
connection to the Internet server has been 
automatically restored. Even without a server 
connection, the heat source can be controlled in 
manual operation or via the time program after it has 
been put into operation.

The serial number and access code are on the sticker, 
which is on the front of the brief installation 
instructions, and on the sticker at the back of the 
EasyControl. If the app is used to log on, the serial 
number and access code can be displayed in the app, 
by navigating via the “Info menu” to the “Product 
information” submenu. If the serial number and access 
code can not be found, please contact “Consumer 
Info”

Does the EasyControl have a connection to the 
Internet (

 section 5.4)? Serial number and access 

code entered? Please note, these are capital letter 
sensitive. There is possibly a slow Internet connection. 
Wait for a few minutes.

The displayed temperature can be set in the app or on 
the EasyControl site

.

If the touch screen does not detect anything for more 
than 5 minutes, it automatically switches itself off. 
After this, the touch screen can only be activated again 
by touching it.

EasyControl uses the standard Wi-Fi protocol. Do not 
therefore use any $ characters in the Wi-Fi network 
password. Remove the $ character from the network 
password.

It is possible that, when delivered, the EasyControl 
does not yet have the current software version. This 
means that possibly not all app functions can be used. 
The software update occurs automatically and make 
take some time.

Indication of one of the following messages: repeated 
ignition attempts, dripping/leaking DHW tap, too little 
flow through the heating system, leak in the heating 
system, boiler pressure too low, or heat source shows 
the Maintenance symbol. These are informative 
signals. The heat source is functioning normally.

The heat source is malfunctioning. Go to the 
EasyControl app for more information.

Software updates are performed automatically. 
This requires a continuous Internet connection. 
If the router is provided with a timer, updates can be 
missed.
