10.2.3 FAULTS OF THE FW200 PROGRAMMING UNIT
Operating and fault indications of the hybrid manager are displayed on
the FW200 programming unit and on the hybrid manager control
module.
The following information given in the service instructions of the FW200
programming unit is prerequisite.
• Principles of operation
•Troubleshooting
INDICATORS ON THE HYBRID SYSTEM
Indicators on the hybrid manager are displayed exclusively on the
internal display of the hybrid control module.
10.2.4 FAULT DISPLAY ON THE FW 200 WEATHER-COMPENSATED
CONTROLLER AT USER LEVEL
Faults are displayed directly at user level ( Fig. 62).
If the heat pump or the boiler is the cause of the fault, this is shown on
the controller display with a corresponding message. The fault number
displayed will contain at least one letter, e.g. Fault d1 or Fault CC (
Tab. 34).
If the cause of the fault (the heat pump or the boiler) cannot be identified
directly from the information in the fault display:
▶ Check the display on the boiler:
– If the boiler is displaying a fault ( technical documentation for the
boiler), the heat pump is not faulty.)
– If the boiler is not displaying a fault ( technical documentation for
the FW200), before proceeding to check the heat pump.)
See the technical documentation for the FW 200 weather-compensated
controller or the relevant technical documentation for more detailed
information about faults caused by other system components.

Cause Remedy (by contractor)
ON 5H Relay test was activated – –
OFF Heating and DHW mode in parallel Hybrid system runs in heating and DHW
mode simultaneously (parallel)
–
OFF Pump pre-run phase in internal unit – –
OFF Heat pump pre-heat phase – –
OFF Heat pump in operation – –
OFF Hybrid manager pump: post-run phase – –
OFF Heat pump in defrost mode – –
OFF Only EMS heat appliance in operation – –
OFF Heat pump blocked: more than 4 starts
per hour
– –
OFF Differential temperature outside the
permissible range
Indicator for low system flow rate. Check
filter for blockages
and clean if necessary
OFF Heat pump operates with the boiler
blocked
– –
OFF Heat pump in service mode The heat pump is running in service mode
(100% heating output)
Switch over to normal mode on completion of
service work. Service mode terminates
automatically after 15 minutes
Table 33 Hybrid manager indicators (internal unit)
The faults are shown in descending order based on
severity.
If a fault has several causes, the next lower-priority fault
is shown after troubleshooting. Tab. 34 lists the faults
sorted by fault no. and code.
