Upon completion of the previous steps, it is mandatory for the installer to upgrade the software of the water
heater to the latest version. Upgrading can be done by the installer, using a mobile phone (pairing with the
water heater is not required), as follows:
1. Download and install the “MyEssency” mobile application from your preferred mobile application store.
2. Launch the mobile application and create an account.
3. Click on ‘Change my WiFi settings’ and follow the steps on the mobile application to connect the water
heater to a WiFi network.
4. Once the procedure is completed, go to the settings menu on the water heater’s touchscreen, (see page 35)
then Upd. After confirmation, the software upgrade will be started. A progress indication will count up from 1
to 100.
5. When the software upgrade is completed successfully, the progress indication on the water heater will be
displaying ‘100’, and the WiFi connection must be turned o if the water heater owner doesn't want to use
the App : SEt -> Con -> Off (see page 35 for Parameter Settings). In case an issue occurs during the
software upgrade, ‘Err’ will be displayed and the procedure should be repeated.
