Description of possible faults
Signs of a fault
Hints
1.
The display is blank
despite connection to
power supply.
Check:
§
if the main fuse is burnt-out, replace if so,
§
if the lead connecting the panel with the module is properly
plugged in, and if
it’s
not damaged
2.
Preset CH temperature
on
the
display
is
different
than
the
programmed one
Check:
§
whether the domestic hot water tank is filled at the time and the
preset domestic hot water temperature is higher than the preset
CH temperature; if so, the difference of readouts will disappear
after the domestic hot water is filled, or after decreasing the
preset domestic hot water temperature.
§
whether the room thermostat is on
–
set the service parameter
Lower preset CH temp. to thermostat
to “0”
§
if the time periods are on
–
enable time periods
3.
CH pump is inoperative
Check:
§
whether the boiler exceeded the parameter
CH pump start temp.
–
wait or decrease the
CH pump start temp.
§
if the room thermostat is not blocking the CH pump - set the
parameter
CH pump start temp. with thermostat on
to “0”.
§
if the DHW priority, which blocks the central heating pump, is
enabled
–
disable the priority by setting the
DHW mode
to
No
priority
,
§
whether the central heating pump is not damaged or clogged.
4.
CH pump switches off
temporarily
§
If this happens when the boiler temperature is 10
o
C lower than
the preset boiler temperature, it is a normal symptom
connected with detection of fuel shortage
5.
The fan is inoperative
§
increase the fan power (parameter
fan power
),
§
check if the safety temperature limiter STB jumper is on
terminals 1-2 (the jumper should be placed only if no
temperature limiter is connected).
§
if the boiler manufacturer equipped it with a temperature limiter
STB with manual return to the initial position, unlock it by
removing the lid and pushing the button, in accordance with the
documentation provided by the boiler manufacturer.
§
Check setting of the parameter
Feeder and Fan power
and set it
to
ON,
§
check the fan and replace it if necessary
6.
Fuel
feeder
inoperative/does
not
feed
§
Check if the feeder leads are properly connected to terminals
§
If temperature limiter STB is connected to terminals 1-2, check if
the circuit is not cut off due to boiler overheating,
§
Check if the feeder motor is in working order,
§
Check setting of the parameter
Fuel feeder and Fan power
and
set it to
ON
,
§
If you can hear the motor working but the fuel is not fed, replace
the cotter pin in the fuel feeder coupling, in accordance with the
boiler manual
7.
When the Fuzzy Logic
mode is on, the fuel is
not burnt out
completely, and there
are fuel remnants in the
ashes
§
Open the fan aperture and/or fan return flap to the maximum
§
Clean ducts which supply air to the furnace
§
Check if the seal between the fan and the boiler casing is in
working order,
§
Make sure that the proper fuel type is selected (if other fuel
types can be selected in the regulator)
–
in the fuzzy logic mode,
combustion of mixed fines and eco-peal coal is not allowed.
§
Unseal the boiler room window, thus providing sufficient
amounts of fresh air.
8.
The
temperature
is
§
Check if there is good thermal contact between the temperature
