A STEADY LIGHT indicates that assistance must be requested, there may be a problem with the microprocessor or internal short circuit.
ONE FLASH indicates that there is air in the system and so the pump is running dry. System will reboot manually every 10 minutes up to 5 cycles. Then once every hour for 10 cycles. In case of failure the circulator will stop.
TWO FLASHES indicate that the circulator is blocked or there is a loss of control over the phase. The pump will attempt a restart using algorithms to perform automatic unlocking. If unsuccessful, an error will be indicated. In this case, the user must perform the restart manually by pressing the on/off button.
THREE FLASHES indicate the electronic board overtemperature. If the temperature returns to normal values the pump reset is automatic. Manual reset is not possible.
