Pump LED diagnose and remedy
The pump have an LED operating status display, this makes it easy
for the technician to search for the cause of a fault in the heating
system.
1. If the LED display lights up continuously green, it means the pump
is running normally.
2. If the LED display is flashing green, it means the pump is running
venting routine. The pump runs during 10min in venting function,
afterwards the installer has to adjust the targeted performance.
3. If the LED is flashing green/red, it means the pump has stopped
operating due to an external reason. The pump will restart by itself
after the abnormal situation disappeared. The probably reason to
cause the problem is that the pump undervoltage or overvoltage
(U<160V or U>280V), you should check the voltage supply. Another
reason is the module overheating, and then you should check the
water and ambient temperature.
4. If the LED is flashing red, it means the pump has stopped
operating, some serious fault has happened(e.g. pump blocked), the
pump cannot restart itself due to a permanent failure and the pump
should be changed.
5. If the LED is not light up, it means no power supply to the pump,
maybe the pump is not connected to power supply, you should check
the cable connection. If the pump is still running, it means the LED is
damaged. Or the electronics are damaged and the pump should be
changed.
Failure diagnosis at the moment of first installation
■ In case nothing is displayed on the user interface, check for any
of the following abnormalities before you can diagnose possible
malfunction codes.
1) Disconnection or wiring error (between power supply and unit
and between unit and user interface).
2) The fuse on the PCB may have run out.
■ If the user interface shows "E8"or"E0" as an error code, there is a
possibility that air exist in the system, or the water volume in the
system is less than the minimum volume.
■ If the error code "E2" is displayed on the user interface, check for
the wiring between user interface and unit.
More error code and failure cause can be found in "Error codes".
