Error Code List
The error codes are split into two groups; shut down codes and blocking codes.
7.2.1 Shutdown Codes
Code
Description
Solution
1
Shut off signal after the flame is out and all
ignition attempts have failed.
Check the gas supply and open any closed
valves.
2
False flame signal. A flame signal is recog-
nised without the gas valve being open.
Check the gas valve. If there is a flame, replace
the gas valve. Check the ionization and replace
as needed.
3
Excess temperature signal from the excess
temperature thermostat. If the thermostat
is open, it will cause an error to occur.
Check the boiler settings (draft curve, max. Tem-
perature, differential gap). Check the supply and
return flow sensors.
5
Speedometer error. The controller requires
a certain fan rotation, but is not receiving a
(correct) speedometer signal.
Check the connection between the fan and the
automatic firing device. Check the fan and re-
place as needed.
11
Errors during the first temperature check.
Initially, the pump’s controller will turn on to
equalize the supply and return flows to with-
in 5 °C of each other. The sensors have
not reached the same values within app. 4
minutes.
Check the supply and return flow temperatures.
Check the sensors and replace as needed.
26
The controller has lost the flame signal 4
times within 240 sec. There is something
wrong with the flame recognition’s reliabil-
ity.
Check the ionisation and clean or replace as
needed.
