LED Indicator Faults Causes Remedies
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.
E04 Undervoltage Power supply too low on mains
side
Check mains voltage
E05 Overvoltage Power supply too high on
mains side
Check mains voltage
E10 Blocking Rotor blocked Activate manual restart or con-
tact customer service
E23 Short-circuit Motor current too high Request customer service
E25 Contacting/ winding Winding defective Request customer service
E30 Excessive temperature
of module
Module interior too warm Check conditions of use
E36 Module defective Electronics defective Request customer service
