Pr12 Temperature differential on “SET H2O” and “SET SANI” for switch-off/on
Allows setting temperature differential on “SET H2O” and “SET SANI” for equipment switch-off and re-ignition.
The equipment automatically switches off placing itself in “STOP FIRE” stand-by position once the
temperature differential (or “SET H2O” or “SET SANI” + Pr12) is exceeded. It will automatically re-ignite below
the temperature differential (in this case only on “SET H2O” or “SET H2O” – Pr12). This parameter can be
increased or decreased if necessary to anticipate or delay equipment switch-off. To avoid continuous switch-
off and re-ignition, it is advised not to excessively decrease this value.
Pr13 Flue gas minimum temperature to consider equipment on
Allows setting the flue gas minimum temperature value to consider equipment on. The equipment changes to
work phase if the flue gas temperature set on this parameter is reached within ignition time (value set on
Pr01); if not, it goes in “NO PELL” or “NO FIRE” alarm. To avoid risk of not reaching sufficient temperature in
ignition phase, it is advised not to excessively increase this parameter value; vice-versa, to avoid the
temperature of the water inside the boiler's body heating the flue gas so that the equipment goes to work
phase (flue gas temperature > Pr13) without pellet igniting, do not excessively decrease this parameter value.
The parameter is not normally changed; however, should it be necessary to do so, the set value goes from 45-
55°C. Below the temperature set in this parameter with manual equipment switch-off “OFF”, the flue gas intake
device electric power supply is also interrupted during switch-off phase.
Pr14 Flue gas maximum temperature accepted “ECO FUMI”
Allows setting the accepted flue gas maximum temperature. The equipment goes to safe work phase called
“ECO FUMI” when reached. The equipment automatically goes to POWER 1 during this phase. The
parameter is not normally modified.
Pr15 Pump activation threshold
Allows setting the system's pump start temperature. The forming of condensate inside the boiler body affecting
its duration and correct equipment functioning can be avoided by increasing this parameter value but not
decrease it.
Pr16 Flue gas intake device speed during ignition phase “LOAD PELL”
Allows setting the flue gas intake device speed when the equipment is working in “LOAD PELLET” phase
(excluding previous pre-load phase if present). If using a difficult to burn "hard" (or dark) pellet, this parameter
value can be increased. The same must also be increased/decreased depending on flue draught.
Pr17 Flue gas intake device speed during start phase “FIRE ON”
Allows setting flue gas intake device speed (revs/min) when equipment is working in “FIRE ON” phase. If
using a difficult to burn "hard" (or dark) pellet, this parameter value can be increased. The same must also be
increased/decreased depending on flue draught.
Pr18 Flue gas intake speed in power 1 work phase
Allows setting flue gas intake device speed when equipment is working in POWER 1. If using a difficult to burn
"hard" (or dark) pellet, this parameter value can be increased. The same must also be increased/decreased
depending on flue draught.
Pr19 Flue gas intake speed in power 2 work phase
Allows setting flue gas intake device speed when equipment is working in POWER 2. If using a difficult to burn
"hard" (or dark) pellet, this parameter value can be increased. The same must also be increased/decreased
depending on flue draught.
Pr20 Flue gas intake speed in power 3 work phase
Allows setting flue gas intake device speed when equipment is working in POWER 3. If using a difficult to burn
"hard" (or dark) pellet, this parameter value can be increased. The same must also be increased/decreased
depending on flue draught.
