7.5 BI-FIRE MID and BI-FIRE Functioning principle
The stove can function just with pellets, just with wood or with both combustion chambers on.
There are two functioning conditions:
Pellet side conditions with “PELL ON”:
it switches on automatically when the wood side switches off;
it is switched on manually;
it switches on with the chrono-thermostat.
Pellet side conditions with “PELL OFF”:
it does not switch on automatically when the wood side switches off;
it is not switched on manually;
if set with pellet side running then when it switches off, it remains off;
it switches on with the chrono-thermostat.
With the wood side on, the pellet side switches off immediately on reaching the temperature set on the “SET
H2O”.
With the wood side off, the pellet side switches off only if, after having reached ”ECO H2O” state, it exceeds
temperature differential set on the Pr12 or “ECO H2O” time set on Pr23 lapses.
ATTENTION
If temperature set on “SET H2O” is reached while pellet side performs ignition cycle, pellet side does not
immediately switch-off but only after having exceeded temperature differential set on Pr12 or after “ECO H2O”
time set on Pr23 has lapsed.
If thermo stove is working with pellet...
- Pellet only (functioning with 5 work powers, functioning economy phase, chrono-thermostat, room thermostat
function active).
- If wood side switches-on (wood fumes temperature ≥ Pr48) the pellet side switches off when the temperature
set on SET H2O is reached.
If thermo stove is working with wood...
- Wood only;
- With wood on, it is possible to switch the pellet side on manually, which will switch-off when the temperature
set on “SET H2O” is reached. To switch the pellet side on, hold key 4 down (switch-on/off);
With “PELL ON” function active:
The pellet side ignites when the wood side switches off i.e.when the flue gas temperature is lower than
150°C (Pr48) and the temperature of the water in the boiler is lower than 60°C (Pr11).
With “PELL OFF” function active:
The pellet side DOES NOT ignite when the wood side switches off i.e.when the temperature of the
fumes is lower than 150°C (Pr48) and the temperature of the water in the boiler is lower than 60°C
(Pr11).
