The following warnings must only be rectified by qualified personnel:
Warning Cause Rectification
W 69 Partial load: stable condition not
achieved
Check the ionisation electrode, replace if
necessary [ch. 9.1.4].
Clean burner surface, if necessary replace
[ch. 9.1.3].
Check wind conditions at flue gas system.
W 1201 Communication error
Check voltage supply at condensing unit.
Switch on switch S1, see [ch. 5.7].
W 1301 …
1324 Communication error
Check CAN-Bus connection to EM heating
circuit.
W 1501 …
1332 Communication error
Check CAN Bus connection to room device 2.
W 1601 …
1632 Communication error
Check CAN Bus connection to room sensor.
W 1701 …
1732 Communication error
Check CAN Bus connection to room device 1.
10.3 Fault codes
The following faults must only be rectified by qualified personnel:
Fault Cause Rectification
F 1 Heating circuit device
:
Communication error EM heating cir-
cuit
Check CAN Bus connection.
F 2 Heating circuit device
:
External sensor (T1) of EM heating
circuit defective
Check the sensor and cable and replace if neces-
sary
F 3 Heating circuit device
:
Flow sensor (B6) of EM heating cir-
cuit defective
Check the sensor and cable and replace if neces-
sary
F 11 Temperature at flow sensor > 105 °C
[ch. 3.3.3]
Temperature is measured at the flow sensor eSTB.
Ensure there is a flow of water.
Increase water flow.
Purge unit on the water side, initiate program
Automatic purging
, see [ch. 6.6.9.6].
Check the heat exchanger on the water side for
contamination or calcification.
F 13 Flue gas temperature too high
[ch. 3.3.3] Check the heat exchanger [ch. 9.1.5].
F 14 Flow temperature rises too rapidly
(gradient)
[ch. 3.3.3]
Temperature is measured at the flow sensor eSTB.
Ensure there is a flow of water.
Increase water flow.
Purge unit on the water side, initiate program
Automatic purging
, see [ch. 6.6.9.6].
F 15 Difference between flow and flue gas
temperature is too great
[ch. 3.3.3]
The flow temperature is measured at the flow
sensor eSTB.
Ensure there is a flow of water.
Increase water flow.
Check heat demand (e. g. heating curve), reduce
if necessary.
Heating capacity too high, reduce parameter
2.1.2 Maximum load heating mode
.
F 19 Flow temperature (VPT) rises too rap-
idly (gradient)
[ch. 3.3.3.2]
Temperature is measured at the flow sensor of the
multifunction sensor VPT.
Ensure there is a flow of water.
Increase water flow.
Function / check the setting of the pump.
Purge unit on the water side, initiate program
Automatic purging
, see [ch. 6.6.9.6].
