04.2 USER FUNCTIONS
Standard operation of a control board correctly installed on an forced air stove is described below with reference to the functions available to users.
The board automatically controls the stove working parameters. Users can manually switch the stove on or off and use the advanced functions, such as the weekly
programmer or the timer.
First Start-up
Upon switching on the board, the display shows the resident software version and then the stove status (OFF in case of first ignition).
Temperature Settings
To open the temperature settings, press button
2
and then
1
and
2
to change the temperature from a minimum of 7 to 40°C. If button
8
is pressed in the temperature
settings, the technical menu opens up.
Working Programme Settings
The working programme actually corresponds to the stove heat output. To open the settings, press button
1
and then
1
and
2
to change the programme from a
minimum of 1 to 5.
Press and hold button
1
down to visualise the measured flue gas temperature and then the flue gas motor speed in revolutions per minute, if the encoder is
connected.
Stove ignition
To ignite the stove, press button
8
for a few seconds. The stove will automatically continue the ignition and heating phase. Upon the first ignition and therefore
the first pellet loading, several ignition cycles need to be carried out in order for the pellets to enter the feeding system.
Stove switch off
To switch the stove off, simply press button

. After a system-controlled cooling phase, the stove is switched off.
System Error Reset
The stove signals any malfunctions detected through the relevant error code and message. Hold button
8
down for approx. 3 seconds until the error message
disappears from the LED display to clear any errors and then switch the stove back on.
Pellet Economy
If during the heating phase the room temperature exceeds the set value, LED
4
switches on and the stove limits its heat output to maintain the set temperature.
If the stove temperature further increases by the T value set in the system parameters, the stove enters the pellet economy mode, then the cooling phase. The
stove automatically resumes operation if room temperature reaches a value below the set value for at least 1 minute.
