operation with a defective probe, contact a qualified person.
ERROR 54 „Digital room unit heating circuit 2 does not respond!“
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the communication between boiler and the digital room unit is disturbed.
WHAT TO DO?
Delete the message. The heating circuit can continue operation because the system continues
running when disturbed communication without room unit. Contact qualified person or LOHBERGER
HEIZTECHNIK customer services as soon as possible.
ERROR 55 "Bufferprobe TOP DISTURBED!"
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the top buffer probe (Bf1) signal of buffer at boiler 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). It is not possible to operate the heating with a defective "top"
buffer probe, contact qualified person.
ERROR 56 "2nd Buffer Hc3/4 probe TOP DISTURBED!"
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the top buffer probe signal where heating cicuits 3 and 4 are connected 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). It is not possible to operate heating circuits 3 and 4 with a
defective "top" buffer probe, contact qualified person.
ERROR 57 "Bufferprobe BOTTOM DISTURBED !"
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the bottom buffer probe (Bf2) signal of buffer at boiler 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). Heating operation can continue if "bottom" buffer probe is
defective; buffer loading status might be calculated incorrectly and thus refill INFO reports might be
triggered incorrectly. Contact qualified person as soon as possible.
ERROR 58 "2nd Buffer Hc3/4 probe BOTTOM DISTURBED!"
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the bottom buffer probe signal where heating cicuits 3 and 4 are connected 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). Heating circuits 3 and 4 can continue operation if "bottom"
buffer probe is defective; buffer loading status might be calculated incorrectly and thus refill INFO
reports might be triggered incorrectly. Contact qualified person as soon as possible.
ERROR 59 „Digital room unit heating circuit 3 does not respond!“
This ERROR report displays a technical failure of the installation only qualified personal can fix!
Displayed if the communication between boiler and the digital room unit is disturbed.
WHAT TO DO?
