19. Description of possible faults
Symptoms Tips
1. There are no signs of
operation of device
despite connection to
the network.
Check:
§
If line fuses are not blown, replace if necessary.
§
If the wire connecting panel with the executive module is plugged
correctly and if module is not damaged.
2. Preset boiler
temperature on the
display is different from
the required one.
Check:
§
If in this time the HW silo is not loaded and if preset temperature is set
above the preset boiler temperature. If so then the difference in
readings will disappear after heating the HW silo or reduce the preset
HW temperature.
§
If time periods are activated – then deactivate time periods.
3. CH pump is not
working.
Check:
§
If boiler exceeded temperature above parameter Temperature of
activating CH pump – wait or reduce value of this parameter.
§
If HW priority is activated which blocks CH pump – deactivate priority
be setting HW pump operation mode on No priority .
§
If CH pump is damaged or blocked.
4. Fan does is not
working.
§
Check if plug jumper is installed for the limiter of safety temperature
STB on terminals 1-2, (the jumper should only be installed only in case
when temperature limiter is not connected).
§
If producer of the boiler has equipped it with temperature limiter STB
with manual return to original position, it should be unlocked by
untwisting the cover and/or twisting the button according to
documentation of boiler producer.
§
Check the fan and replace it if necessary.
5. Additional feeder is not
working (module B).
§
Check if feeder wires are correctly connected to terminals.
§
Check if there is a jumper on terminals 1-2 of module B.
§
Check if feeder engine is not damaged.
§
In case when engine work can be heard and fuel is not provided check
the feeder with its user manual.
6. Fuel feeder is not
working / does not
provide fuel
§
Check if feeder wires are correctly connected to terminals.
§
If temperature limiter STB is connected to terminals 1-2, then check if
the circuit is not cut off due to boiler overheating.
§
Check if feeder engine is not broken or damaged.
§
In case when engine work can be heard and fuel is not provided check
the feeder with its user manual.
7. Fuel is not burnt off
completely, there are
not burnt remnants in
ashes. Fuel burns with
big amount of smoke,
burner fades.
§
Check settings Power modulations in: Menu
→
Boiler settings
→
Power modulation .
8. Temperature is not
measured correctly.
§
Check if there is a good thermo contact between the temperature
sensor and measured surface.
§
Check if sensor wire not goes too closely to network wire.
§
Check if sensor is connected to terminal.
§
Check if sensor is not broken – check with point 12.9.
9. In HW pumps mode =
SUMMER heaters are
hot,
boiler is
overheated.
§
Increase value of parameter HW pump operation time extension to cool
off the boiler.
10. HW pump is not
working, even if HW silo
is loaded
§
Set the parameter HW pump operation time extension = 0
