Menu M7 – SET TECHNIC
This menu item is reserved to the stove installer. After entering the password, P1 (increase) and P2 (decrease) buttons allow all the stove working parameters to
be set.
USER FUNCTIONS
Standard functioning of a control board properly installed on an air stove is described below with reference to the functions available to users.
Stove ignition
Hold P4 button down for a few seconds to switch on the stove. The display shows the message “START” when the stove is on.
During this phase the stove goes into the pre-heating status: the ignition plug (as indicated by the relevant LED) and the exhaust blower switch on.
Any problem detected during the switching-on phase is indicated on the display and the stove goes into the alarm status.
Pellet feeding
The pellet feeding phase starts after approx. 1 minute: the message “LOAD PELLET" scrolls on the display. During the first stage the auger tube feeds the pellets
to the burn pot for a fixed period of time. During the second stage the auger tube switches off (auger tube LED off), while the exhaust blower speed and the ignition
plug remain as in the previous status. In case of ignition failure at the end of this phase, the auger tube and the ignition plug remain on.
Fire present
Once fume temperature has reached and exceeded a pre-set threshold, the stove goes into the ignition mode and the message “FLAME LIGHT” appears on the
display.
The exhaust blower speed is fixed, the auger tube remains on for a determined period of time (auger tube LED flashing) and the ignition plug is off (ignition plug
LED off). Any problem during this phase will cause the control board to stop and the stove to go into error state.
Stove operational
Once fume temperature has reached a given value, maintaining it for a pre-set period of time, the stove enters the normal working mode. The upper display shows
the time and room temperature, while the lower display shows the heat output set and the actual heat output of the stove. Press buttons P5 and P6 to set the heat
output and buttons P1 and P2 to set the room temperature. If fume temperature reaches the threshold set, the air exchanger fan will switch on.
During this phase, the stove performs a cleaning of the burn pot. The message “CLEAN BRAZIER” scrolls on the display, the Auger tube is on (as the relevant
LED) and the exhaust blower is on. Once the set period of time has elapsed, the stove goes back to the working mode.
Changing set heat output
During stove normal operation (working mode), the heat output can be changed by using the P5, P6 buttons. Press P6 button again to increase the heat output
and P5 button to decrease it. The display will show the set heat output. Do not press any button for 5 seconds or press P4 button to exit the setting mode.
Changing set room temperature
Press P1 and P2 buttons to change the room temperature. The display shows the set room temperature (SET temperature value). Press P1 and P2 buttons to
increase or decrease, respectively, the temperature value. The value is saved after approx. 5 seconds and the display goes back to normal. Otherwise, press P4
to exit. You can also set “Man”; the stove will operate in “MAN” manual mode, at a fixed heat output. Or t-e, if you connected an external thermostat.
Room temperature reaches set value (SET temperature value)
When the set room temperature value is reached, the stove heat output is automatically set to the minimum value. During this phase the display shows the
message “MODULAT-”. If room temperature falls below the set value (Set temperature value), the stove will go back to “Working” mode and to the previously set
heat output (Set heat output value). If there is an external thermostat and the room temperature has been set to t-e, if the thermostat is open it will begin modulation
and if closed, it will return to the heat output set.
Stand-by
When enabled in the menu, the STAND-BY function allows the stove to be switched off after complying with the following conditions. It is enabled if the room
temperature exceeds the relevant set value (Set room temperature value) plus a pre-set temperature delta for a certain period of time. The message "SO-STBY"
appears on the display followed by the minutes left. At the end of the period of time set, the message (ATTESA RAFFRED-) “Wait for cooling" will appear on the
display. During this phase the auger tube is off (Auger tube LED off) and the exchanger switches off. When fume temperature reaches the relevant threshold, the
stove goes into the Stand-by mode and the message “STOP ECO TEMP OK” scrolls on the display. The Auger tube (Auger tube LED off), the exchanger
(exchanger LED off) and the exhaust blower are off.
If room temperature falls below the set value (Set room temperature value) plus the threshold set by the temperature delta, the stove switches back on.
Stove switch off
Hold P4 button down to switch off the stove. The display shows the message (CLEANING FINAL). The Auger tube motor stops (Auger tube LED off) and the
exhaust blower speed is pre-set. The fan of the exchanger (exchanger LED on) remains active until the fume temperature falls below the pre-set value. After a
given time, if the fume temperature is below the given threshold, the stove switches off, displaying the message “Off”.
ALARMS
Should any malfunctioning be detected, the control board reports the problem in question: the alarm LED switches on (alarm LED on) and the buzzer goes off.
In case of alarm, the stove is always immediately switched off
EXCEPT FOR THE POWER OUTAGE ALARM, the alarm status is reached after a given time and can be cleared by holding P4 button down. Whenever an alarm
is cleared, the stove starts a switching-off phase for safety reasons. The alarm LED (alarm LED on) will remain on and the buzzer, if enabled, will sound
intermittently during the entire alarm phase. Should the alarm not be cleared, the stove will in any case be switched off and the alarm message will remain on the
display.
AL1 BLAC-OUT - Power outage alarm
Power outage may occur with stove in working mode. When power resumes, if the power outage period has been lower than the value set by a 20 second
parameter, the stove will restart in the WORKING mode. The message “AL1 BLAC-OUT” scrolls on the display and the stove switches off.
AL2 PROBE EXHAUST - Fume temperature sensor alarm
The alarm is triggered in case of faulty fume sensor. The stove goes into the alarm status and the alarm LED switches on (alarm LED on). The message “AL2
PROBE EXHAUST” will scroll on the display and the stove will switch off.
AL3 HOT EXHAUST - Fume overtemperature alarm
The alarm is triggered whenever the fume sensor detects a temperature higher than a fixed set value, which may not be modified by means of a parameter. The
message “AL3 HOT EXHAUST” appears on the display and the stove switches off.
AL4 FAN FAILURE - Faulty fume encoder alarm
The alarm is triggered in case of exhaust blower failure. The stove goes into the alarm status and the message “AL4 FAN FAILURE” will scroll on the display.
AL5 NO LIGHTIN- - Ignition failure alarm
The alarm is triggered in case of ignition phase failure. This happens if after the relevant given time, the fume temperature does not exceed a given threshold.
The message “AL5 NO LIGHTIN- " scrolls on the display and the stove goes into the alarm status.
AL6 NO FIRE - No pellet alarm
The alarm is triggered when fume temperature falls below a given parameter. The message “AL6 NO FIRE" scrolls on the display and the stove goes into the
alarm status.
AL7 SAFETY THERMAL - Thermal safety overheating alarm
The alarm is triggered whenever the general safety thermostat detects a temperature exceeding the trigger threshold.
