Code Warning
Additional information about causes and remedy:
If flow passing through pump in the opposite direction is too strong, the motor can no longer start.
551 Undervoltage
Additional information about causes and remedy:
The pump is running. Undervoltage reduces the pump's performance.
If the voltage continues to drop, reduced operation cannot be maintained.
552 There is externally generated flow through
the pump in the direction of flow.
Additional information about causes and remedy:
The pump can start despite flow.
553 Electronic module is defective.
Additional information about causes and remedies:
The pump is running, but may not be able to provide full power. Contact service.
1)
554 MFA pump is not reachable.
Additional information about causes and remedy
1)
In the MFA overview, check the pump highlighted with (!).
The supply is ensured, a substitute value is assumed.
555/ Implausible sensor value at analogue input
557/ AI1, AI2, AI3 or AI4.
591/
594
Additional information about causes and remedy
Incorrect sensor values may lead to substitute operating modes
that ensure functioning of the pump without the required sensor value.
556/ Cable break at analogue input AI1, AI2, AI3
558/ or AI4.
592/
595
Additional information about causes and remedy:
Cable break detection may lead to substitute operating modes that ensure functioning of the pump without the required
external value.
560 Incomplete software update.
Additional information about causes and remedy:
Software update was not carried out; pump continues to operate with previous software version.
561 Voltage digital input overloaded (binary).
Additional information about causes and remedy:
Binary inputs are impaired. Functions of binary inputs are not available.
562 Voltage analogue input overloaded (ana-
logue).
Additional information about causes and remedy:
Analogue input functions impaired.
563 Sensor value missing from BMS
management system).
Additional information about causes and remedy:
Control functions impaired. A replacement function is active.
564 Setpoint missing from BMS
220
Cause
Power supply too low.
Power supply has fallen below a
minimum limit value.
External influences cause flow in
the pump's direction of flow.
Electronic module is defective.
1)
A MFA partner pump no longer re-
acts to requests.
The configuration and the present
signal lead to an unusable sensor
value.
The configuration and the present
signal help identify the cable break.
The software update was not com-
pleted.
Voltage digital input short-circuited
or too heavily loaded.
Voltage analogue input short-cir-
cuited or too heavily loaded.
2)

Remedy
Check power supply.
Check power control of the other
pumps.
Replace electronic module.
Check Wilo Net connection or
power supply of the partner pump.
Check configuration of the input
and connected sensor.
Check configuration of the input
and connected sensor.
Software update with new software
bundle is recommended.
Check line and consumers connec-
ted to power supply of digital input
for short-circuit.
Check line and consumers connec-
ted to power supply of analogue in-
put for short-circuit.
