The factory settings can be restored using the INIT button (see chapter 10 for a description of the
INIT button functionalities).
14.2.40. Registers WEB_PASSWORD[0:3]
These registers contain the web password of the controller.

WEB_PASSWORD0 : bytes 0 and 1 of the web password

WEB_PASSWORD1 : bytes 2 and 3 of the web password

WEB_PASSWORD2 : bytes 4 and 5 of the web password

WEB_PASSWORD3 : bytes 6 and 7 of the web password
The factory settings can be restored using the INIT button (see chapter 10 for a description of the
INIT button functionalities).
14.2.41. Register REMOTE_TEMPERATURE
The controller allows for the connection of an external temperature sensor (see section 7.4.4 for more
information).
This register contains the measured temperature, expressed as a signed sixteen bits integer, with a
resolution of 0.1 °C. Given the register value, the corresponding actual temperature for the remote
sensor can be calculated as follows:
RemoteTemperature [°C] = value(REMOTE_TEMPERATURE) * 0.1
In case the external temperature sensor is not connected, the value in the register is undefined.
14.3.42. Register BOARD_TEMPERATURE[0:3]
The controller integrates four temperature sensors. There is a temperature sensor for every couple of
power stages.

BOARD_TEMPERATURE0 : average temperature of LD1 and LD2 power stages

BOARD_TEMPERATURE1 : average temperature of LD3 and LD4 power stages

BOARD_TEMPERATURE2 : average temperature of LD5 and LD6 power stages

BOARD_TEMPERATURE3 : average temperature of LD7 and LD8 power stages
These registers contain the measured temperatures, expressed as signed sixteen bits integers, with a
resolution of 0.1 °C. Given a register value, the corresponding actual temperature for a couple of
power stages can be calculated as follows:
BoardTemperature[x] [°C] = value(BOARD_TEMPERATURE[x]) * 0.1
The average heatsink temperature may be estimated by averaging the temperatures measured by the
four temperature sensors.
14.2.43. Register SUPPLY_VOLTAGE
The controller is capable of measuring the actual supply voltage for the power stages.
This register contains the measured supply voltage, expressed as an unsigned sixteen bits integer,
with a resolution of 0.1 V. Given the register value, the corresponding actual supply voltage for the
power stages can be calculated as follows:
