3.2.2 Failure Operation - Control Panel Functions not available
When the ignition is switched on, the control panel and the main relay board
intercommunicate. In case there is an intercommunication failure, the control
panel will indicate
after 15 seconds and the main relay board will
automatically activate the AUTO function with the set-point of 22 °C. After the
first communication, the system works with the last temperature setting.
This is a failure condition, although it enables the equipment to work even
without communication between the modules.
If the equipment is operating and there is a communication failure, it will
continue operation on the selected function until the ignition is switched off.
Alternator voltage
above 33 Volts.
To restore normal operation, the AUTO key
must be pressed and pressed a second
time after a period of at least 10 seconds. If
the failure persists the failure indication will
come on again.
Alternator voltage
below 21 Volts.
The system operates with reduced perfor-
mance. When the alternator reaches the
normal level, the system will resume its
operational condition before fail taking into
account the possible change of control pa-
rameters.
Alternator voltage
below 18 Volts.
To restore normal operation, the AUTO key
must be pressed and pressed a second
time after a period of at least 10 seconds. If
the failure persists the failure indication will
come on again.
Battery voltage
above 31 Volts.
When the battery reaches the normal level,
the system will resume its operational con-
dition before fail taking into account the
possible change of control parameters.
External temperature
below the minimum re-
quired for operating
the system (8 °C) with
reheat mode enabled.
When the external temperature is above
8°C the system will resume its operational
condition before fail taking into account the
possible change of control parameters.
