Bios Alarms - Ferroli RHV R134a Instruction Manual

BIOS ALARMS

They solely concern HW and SW operation of the micro-controller and do not involve the machine components (compressors,
pumps, sensors, etc.)
After selecting the bios alarms menu, all active bios alarms are displayed.
The bios alarms can end automatically or can last until operator intervention.
For example: The RTC battery alarm (RTC= Real Time Clock), while not being a cause of failure, shuts down the
machine until the current date and time are set correctly.
If there is no bios alarm the "EMPTY" string is displayed for 2 seconds.
