Firmware release 1.16

Cleaning mode activation

To avoid that cleaning mode gets activated unintentionally, the procedure to enable it has been slightly modified.

• There is no longer an immediate visual change to the LED ring and status LED once the upper ToF is triggered.

• The delay before cleaning mode is activated is changed from 3s to 10s.

Bugfix: shortly triggering top ToF cancels usage detection

In FW 1.15, briefly triggering the upper ToF reset the usage detection, allowing an automatic flush to be unintentionally cancelled. In firmware 1.16 this bug has been resolved.
