User functions

Standard functioning of a control board properly installed on a stove is described below with reference to the functions available to users. The
indications listed below refer to a control board fitted with programmable thermostat.
Turning on the stove
Make sure that there are pellets in the hopper, that the burn pot is correctly positioned and clean from any combustion residues and then close
the door.
To switch the stove on, act on P4 for a few seconds. The display shows that the stove is on.
Start-up phase
The appliance performs the start-up phases in sequence according to the methods defined by the parameters that manage levels and times. The
display will show the wording ON, as there is no pellet loading but the fume fan is operating. PELLET LOADING state will occur where the pellets
are being loaded into the burn pot. Once the pellets have started to burn and the fume temperature is increased, the display will show FIRE ON,
a transition phase between ignition and operating power.
Ignition failure
After a predefined time, if the fume temperature has not reached the minimum permitted value, reached with a ramp of 2°C/min, the appliance
goes into alarm status.
If there are unburnt pellets inside the burn pot, it is necessary to empty the burn pot before switching the stove on again. This will avoid wasted
pellets and possible spillage within the combustion chamber.
If the pellets have begun to burn but the alarm state persists, wait until all the pellets are burning and then switch on again.
Check that there are pellets inside the hopper.
Stove operational
At the end of the start-up phase, if no problems occurred, the stove enters its normal working mode.
When the flue gas temperature is the same as that set by the parameters, the fan is switched on.
Once the set temperature has been reached, the appliance will go into MODULATION and automatically work at minimum power.
Every 8 hours of continuous work the appliance performs an automatic switch-off in order to guarantee cleaning of the burn pot.
Changing set room temperature
Press the P2 button to change the set room temperature. The display shows the current SET temperature value.
It changes the appliance's temperature setting
Press P1 button to change the set room temperature. The display shows the current SET temperature value.
External thermostat/chronothermostat use
If you want to use an external programmable thermostat, connect it to the TERM clamps (connector CN7 pin 7-8).
•
external thermostat
•
external chronothermostat
To enable the thermostat bringing the room temperature below 7°C when the wording T-E appears.
The stove external thermostat is enabled when the contact is closed with stove on.
Room temperature reaches the set value (SET temperature)
When the set room temperature value is reached or the fume temperature has reached the safely value, the stove heat output is set automatically
to the minimum value, MODULATION mode.
If the stove is in the STAND-BY mode, it switches off with a delay equal to a pre-set time after reaching the SET temperature. Restart takes place
after occurring of the condition in which the ambient temperature lowered.
Cleaning of the burn pot
When the stove is in the working mode, the "BURN POT CLEANING" mode is activated for the period determined by a pre-set parameter at certain
intervals.
Switching off the appliance
To switch off the appliance simply press the P4 button for approximately 2 seconds. The Auger tube stops immediately and the exhaust blower
reaches its maximum speed value. The FINAL CLEANING phase is performed.
