1�
Check the cables connecting the room unit/s to the
RVS21.826 controller:
„
No short circuits between the wires
„
No broken wires
„ Correct wire polarity on controller and room unit/s
„
Stable, secure connection of all cables to all controller
and room unit terminals
Correct any problems.
2� If step 1 does not resolve the problem:
„
Power the System controller off and on again; if the
problem persists, contact the Robur Technical Sup-
port Centre.
D Code 84
This problem occurs when two room units are connected and
they are both configured as the same type of device (e.g., both
as room unit 1).
1� Resolve the problem as indicated in par. 5.1.7 p. 34, Case
3, to configure the two room units correctly.
2� If step 1 does not resolve the problem:
„
Power the System controller off and on again; if the
problem persists, contact the Robur Technical Sup-
port Centre.
E Code 127
This problem is caused by fault to reach and maintain the le-
gionella function setpoint while the function is executing.
1� Check sensor B3:
„ Check the position and thermal contact of probe B3
in its mounting on the DHW tank. Correct the prob-
lem.
2� If step 1 does not resolve the problem:
„ Check the setpoint setting (parameter 1645, see also
par. 5.2.1 p. 34 and 5.2.3 p. 35) and set a lower
value if necessary, especially if no auxiliary boiler is
present.
3� If step 2 does not resolve the problem, check the installa-
tion's water circuits:
„
Water outlet during DHW charging.
„
Proper sizing of the coil exchanger in the DHW tank
(exchange surface area).
4� If step 3 does not resolve the problem, contact the Robur
Technical Support Centre.
F Code 324
This error is generated if two or more BX temperature sensors
have been configured to a single function.
1� Check the configuration:
„
Access the Engineer menu level, then the Configura-
tion menu, and select parameters:
- 6014 (Function mixing group 1); set it to
Multifunctional;
- 5930 (Sensor input BX1); check that it is set to Out-
side sensor B9; if not, set it to that value;
- 5931 (Sensor input BX2); check that it is set to none; if
not, set it to this value;
- 5932 (Sensor input BX3); check that it is set to DHW
sensor B3; if not, set it to this value;
- 5933 (Sensor input BX4); set it to none;
- 6014 ( Function mixing group 1); set it to Heating
circuit 1.
„
Run sensor memorization: access the Engineer menu
level, thent the Configuration menu; select param-
eter 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:
„
Power the System controller off and on again; if the
problem persists, contact the Robur Technical Sup-
port Centre.
G Codes 330, 331, 332, 333
This problem is due to the physical presence of a sensor con-
nected to one of inputs BX1, BX2, BX3, BX4, to which no func-
tion is assigned.
1� Check the configuration:
„
Access the Engineer menu level, then the Configura-
tion menu, and select parameter:
- Error code 330: 5930 (Sensor input BX1); check that
it is set to Outside sensor B9; if not, set it to this value.
- Error code 331: 5931 (Sensor input BX2); remove the
optional sensor connected to input BX2 (not used in
the standard configurations).
- Error code 332: 5932 (Sensor input BX3); check that it
is set to DHW sensor B3; if not, set it to this value.
- Error code 333: 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.
„ Run sensor memorization: access the Engineer menu
level, thent the Configuration menu; select param-
eter 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:
„ Power the System controller off and on again; if the
problem persists, contact the Robur Technical Sup-
port Centre.
H Code 173
This error is generated when the K18 unit activates its alarm out-
put. This is therefore a signal of an error of the K18 unit and not
of System controller.
In the case of K18 Hybrigas unit, or K18 Simplygas unit
and in the presence of the auxiliary boiler and connec-
tion of its alarm signal to the specific input of the K18
unit, the error can also be generated by the auxiliary
boiler.
1� You can read the error code (or codes) of the heat pump of
the K18 unit by viewing its display through the transparent
window on the right side of the casing. The E495 error code
indicates the presence of an alarm of the integrated boiler
module of the K18 Hybrigas unit or the optional auxiliary
boiler connected to the K18 Simplygas unit.
If there are multiple errors, the K18's display will cycle
through their codes. For further details and an explana-
tion of the meanings of the error codes, refer to the K18
unit's Installation, user and maintenance manual .
2� The error conditions of the heat pump of the K18 unit can be
