Plum ecomaxx 800 R2 User Manual

7. When the Individual
Fuzzy Logic mode is on,
the fuel burns out too
intensively.paliwa
 reduce fuel feeding rate by lower setting of the parameter Fuel
correction in Fuzzy Logic mode. See sec. 7.8,
 check whether incompletely burnt fuel comes from operation in
SUPERVISION mode. If YES- adjust this mode acc. sec. 11,
 check whether incompletely burnt fuel is produced by frequent
change-over from SUPERVISION to OPERATION mode and V/V,
Cycle order OPERATION acc. sec. 35,
 if the regulator has the option of fuel type selection - make sure
the correct fuel type has been selected (see sec. 7.10 – Fuzzy
Logic mode does not allow burning a blend of fine coal and ECO-
pea coal),
 check whether correct type of boiler/ burner has been selected.
See sec. 21.1
 open fully fan baffle and/ or return flap
 clean off ducts supplying air to the furnace
 change Fuzzy Logic settings in: MENU → Service Settings →
Boiler Settings → Burner Settings → Fuzzy Logic (accessible to
boiler manufacturers only)
8. When Fuzzy Logic mode
is active, combustion is
too intensive and the
furnace lowers into
retort.
 increase fuel feeding rate by higher setting of the parameter Fuel
correction in Fuzzy Logic mode. See sec. 7.8
 check whether too intensive combustion occurs in SUPERVISION
mode. If YES - adjust this mode acc. sec. 11,
 check whether too intensive combustion is caused by the setting
Cycle order OPERATION - see sec. 35,
 if the regulator has the option of fuel type selection - make sure
the correct fuel type has been selected (see sec. 7.10),
 check whether correct type of boiler has been selected. See sec.
21.1.
 change Fuzzy Logic settings in: MENU → Service Settings →
Boiler Settings → Burner Settings → Fuzzy Logic (accessible
only to boiler manufacturers only)
9. The temperature is
measured incorrectly
 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 11.9
10. In the DHW=SUMMER
mode, the radiators are
hot and the boiler
overheats.
 increase the setting of the parameter: HUW pump operation
extension time to cool down the boiler. See sec. 36,
 increase the setting of the parameter: max. HUW temperature to
enable excessive heat discharge to HUW container. See sec. 40,
Note: inform the users of high temperature of hot utility water!
11. the DHW pump is active
even if the DHW tank
has been filled.
 Set the parameter HUW pump operation time extension = 0
12. The boiler overheats
despite disabled airflow.
 the reason may be boiler defect or improper chimney design -
lack of protection against too excessive flue draught.
