WHAT TO DO?
Delete the message (see point 8). Heating circuit can continue operation because the system
ignores the room device operational mode switch and temperature dial if "switch" is defective.
Contact qualified person as soon as possible.
ERROR 47 "Roomdev.2 probe DISTURBED!"
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the Roomdev 2 probe signal is either far over or under the normal range (larger than
+130°C or smaller than -30°C).
Error might be caused by e.g. a wrong room device, or a failure of the room device.
WHAT TO DO?
Delete the message (see point 8). Heating circuit can continue operation because the system runs
with a default value of 15°C if probe is defective. Contact qualified person as soon as possible.
ERROR 48 "Roomdev.2 switch DISTURBED!"
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the "remote control" signal (operational mode – switch or termperaturedial) at heating
circuit 2 lies either far over or far under the normal range (larger than 4900 ohm or smaller than 20
ohm).
Error can be caused by e.g. a wrong connection, or because a wrong room device has been
mounted. But it can also be caused by a room device failure.
WHAT TO DO?
Delete the message (see point 8). Heating circuit can continue operation because the system
ignores the room device operational mode switch and temperature dial if "switch" is defective.
Contact qualified person as soon as possible.
ERROR 49 currently not available!
ERROR 50 "Primary or Second.airflap DID NOT GET TO requ. POSITION!"
This ERROR report displays a possible technical failure at the boiler or installation only qualified
personal can fix.
Displayed if either primary or secocdary airflap does not reach the required position because it is
e.g. blocked.
WHAT TO DO?
Delete the message (see point 8). Heating operation not possible, contact qualified person.
ERROR 51 currently not available!
ERROR 52 „Clean OXYGENPROBE!“
This ERROR report displays a technical failure at the boiler only qualified personal can fix!
Displayed if at the end of the log burnoff process the combustion chamber temperature is signalling
that burnoff has finished (for it has fallen below the Off detection thresholds), but the oxygen probe
provied contradictory values. In this case either the probe is only contaminated or it is defective.
WHAT TO DO?
Delete the message (see point 8).
For the technically gifted, the probe removal is reasonable.
It is located beneath the rear sheet metal lid. First, the cap nut has to be removed with a pipe
wrench and unscrewed, then the probe can be slid off. Remove the dust accumulated inside the
probe by gently blowing air to the probe tip. Check if the pipe piece the probe has to be screwed
into is free from any residues before reassembly.
ERROR 53 "Dom.water1 probe DISTURBED!"
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the domestic hot water 1 probe signal is either far over or under the normal range
(larger than +130°C or smaller than -30°C).
The mistake can lie with the probe itself (e.g. moisture intrusions) or with cable, clamps, or plugs.
WHAT TO DO?
Delete the message (see point 8). The affected domestic hot water circuit cannot continue
