> Errors diagnostics:
In diagnostics state:
- TEMPER TURE LEDS shall encode the error.
- ECO led shall be off.
- RE DY (with ECO version) leds shall be off.
- WIFI led (with WIFI version) state is given by Wifi state
If more than one occurs, the one to be shown depends on priority (1 is highest). So, for
example, if Error Relay Stuck occours and in a second time an NTC short is checked, only
the Relay error with a highest priority is shown. Errors codification is given by tables
below.
If a new error occurs while the HMI is in diagnostics state, the HMI shall not leave this
state and the diagnostics shall not be updated.
fter 25 seconds the system will come back in lockout state, but if error is removed
before timeout elapses the diagnostic state is not left.
Errors codification is given by tables below. The led on the left is the 40°C led, while the
one on the right is 80°C led.
