D.149
Explanation for fault F.75
Defined displays for the fault analysis
0 = No fault
1 = Pump blocked
2 = Electrical pump fault
3 = Dry fire
4 = Alarm, voltage at pump is too low
5 = Pressure sensor fault
6 = No signal from the pump (PWM)
D.152
Type of output limiter
Defines the phase for which the output has to be
limited.
0 = No limit
1 = Phase 1
2 = Phase 2
3 = Phase 3
4 = All phases
D.153
Output limiter value
Only effective if D.152 has been set.
The value for the output limit in kW. This value is
subtracted from the current product output in the
phase(s).
D.154
Frost protection function
Deactivation of the frost protection function (frozen
component)
D.155
Current power
The product's current output (continuously updated
information)
Not ad-
justable
C
Overview of fault codes
If a fault occurs, the display for the fault code replaces all of the other displays. "F" and the fault code appear alternately in
the display.
Code
Meaning
Remedy
F.000
Interruption: Temperature sensor (NTC)
Temperature sensor (NTC) defective
Temperature sensor cable (NTC) defective
Plug connection at the NTC defective
Plug connection at the electronics defective
F.010
Short circuit: Temperature sensor (NTC)
Plug-on sensor has a short to earth at the housing
Short circuit in the cable harness
Sensor defective
F.013
Short circuit: Cylinder temperature sensor (NTC)
F.020
Safety shutdown: Safety cut-out
–
Switch the product back on.
–
Bypass the safety cut-out. When the product is started up again,
replace the safety cut-out.
–
Bypass the temperature control. When the product is started up
again, replace the temperature control.
–
Replace the PCB.
–
Replace the cable harness.
F.022
Dry fire
–
Check the product for low water pressure (< 0.06 MPa (0.6 bar)).
–
Check all of the heating system's connections for leaks.
–
Check that the expansion vessel works correctly.
–
Purge all radiators.
–
Increase the filling pressure of the heating installation.
F.024
Safety shutdown: Temp. incr. too fast
Pump blocked, insufficient pump output, air in product, system pressure
too low, non-return valve blocked/incorrectly installed
F.049
Fault: eBUS
Short circuit on eBUS, eBUS overload or two power supplies with differ-
ent polarities on the eBUS
F.063
Fault: EEPROM
Electronics defective
–
Reset the product to its factory settings (
D.096
).
F.070
Fault: Invalid Device Specific Number (no valid
Device Specific Number detected for the display
and/or electronics)
Scenario for replacing parts: Display and electronics were replaced at
the same time and the Device Specific Number was not reset.
Incorrect or missing coding resistor for the output range
