| Pump is not running although the power supply is switched on | Electrical fuse | ||
| defective | Check fuses | ||
| Pump has no voltage | Resolve the power interruption | ||
| Pump making noises | Cavitation due to insufficient suc- tion pressure |
Increase the system pressure within the permissible range
Check the delivery head and set it to a lower head if necessary
Building does not get warm| Thermal output of the heating surfaces is too low|
Increase setpoint
Set control mode to Δp-c
Warning signals is indicated by the LED display. Fault signal LED does
not light up.
E07| Generator operation| Water is flowing through the pump hydraulics, but
pump has no mains voltage| Check mains voltage
E11| Dry run| Air in the pump| Check volumetric flow rate/water pressure
E21| Overload| Sluggish motor, pump is opera- ted outside of its
specifications (e.g. high module temperature). The speed is lower than during
normal operation.| Check the ambient conditions
Fault signals is indicated by the LED display. Fault signal
LED lights up red.
