6.1 LIST OF ERRORS AND
TROUBLESHOOTING INSTRUCTIONS
Table 6.1 p. 37 lists the error codes, their descriptions and pri-
orities, which may be generated by the System controller for the
K18 when configured to support the circuits envisaged in this
manual. The last column of the table lists measures for resolving
the problem.
Errors are shown on the QAA75.611 room unit's display with the
symbol
. If you press ( ) when this symbol is displayed, the
unit will display the code and description of the highest priority
error. No other errors will be displayed until this error is resolved.
Errors are usually reset automatically when the problem in ques-
tion is resolved; only if the display also shows the wording Reset
? at the bottom left and Yes at the bottom right need the error
be explicitly reset; to do so, press OK twice (after having resolved
the problem in question, otherwise the error will simply repeat).

Troubleshooting measures
A Codes 10, 30, 50
1� Memorize the sensors:
„
Access the Engineer menu level, then the Configura-
tion menu; select parameter 6200 (Save sensors),
set it to yes and confirm.
The value of parameter 6200 which displays at the end
of the configuration procedure will still be no; this is
normal (this setting executes an action, i.e. memoriza-
tion of the actually installed sensors).
„ Wait for a minute.
2� If step 1 does not resolve the problem:
„
Check the connection of the sensor in question, cor-
rect it and memorize the sensor again as indicated in
step 1.
3� If step 2 does not resolve the problem:
„
Disconnect the sensor from the RVS21.826 controller
and measure the resistance between the cable's two
wires. If the measurement indicates a short or open
circuit, identify and resolve the problem, which may
be due to the sensor itself or its wiring. Once the
problem has been resolved, reconnect the sensor and
memorize it again as indicated in step 1.
4� If step 3 does not resolve the problem:
„
Access the Engineer menu level, then the Configura-
tion menu, and select parameter:
- Error code 10: 5930 (Sensor input BX1); check that it
is set to Outside sensor B9; if not, set it to this value.
- Error code 30: 5933 (Sensor input BX4); check that it
is set to the value used by parameter 6014; if not, re-
maining in the Engineer menu level, menu Configura-
tion, select parameter 6014 (Function mixing group
1) and set it to Heating circuit 1.
WARNING: This sensor is used only if heating circuit 1 is
mixed, otherwise no sensor should be con-
nected to input BX4. If a sensor is connected
to the input by mistake, remove it, then run
sensor memorization again as indicated in
step 1
- Error code 50: 5932 (Sensor input BX3); check that it is
set to DHW sensor B3; if not, set it to this value.
WARNING: This sensor is used only if DHW production
is performed by the K18 unit, otherwise no
sensor should be connected to input BX3.
If a sensor is connected to the input by mis-
take, remove it, then run sensor memoriza-
tion again as indicated in step 1.
„
Run sensor memorization again as indicated in step 1.
5� If step 4 does not resolve the problem:
„
Power the System controller off and on again; if the
problem persists, contact the Robur Technical Sup-
port Centre.

2� If step 1 does not resolve the problem:
„
Check the communications between the controller
and the room unit/s and their configuration (see par.
5.1.7
p. 34). Resolve the problem, then run sensor
memorization again as indicated in step 1.
3� If step 2 does not resolve the problem:
„
Power the System controller off and on again; if the
problem persists, contact the Robur Technical Sup-
port Centre.
