WARNING: Multiple alarms are displayed one at a time.
WARNING: - The triggering of alarm n. 4 (faulty sensor) and/or the control unit failure alarm determine the automatic
starting of the system with pressure switches (check the efficiency of the expansion tanks).
- The triggering of alarm n. 16 (inverter failure) disconnects the pump powered by the inverter and maintains
pressure regulation by the Systemcontroller.
The message "MOTOR MAINTENANCE alarm 1" is cancelled by moving the cursor to
table 8.2.3, the motor that is scheduled for maintenance, then selecting ON using the
