Operation Manual

Menu M4 – SELECT LANGUAGE
Use this function to select one of the languages available.
Menu M5 – SELECT FEELER
Use this menu to select the internal or the remote control sensor
Menu M6 – MODO STAND-BY
If you select the “MODO STAND-BY” mode, the stove switches off after a period of time, set by Pr44, during which the room temperature remained at a value higher
than the SET temperature.
Only if the following condition occurs -
T
SET
< (T
ambiente
- Pr43), it is then possible to switch the stove back on.
Menu M7 – MODE BUZZER
Set it to “OFF” to disable the buzzer.
Menu M8 – LOAD INITIAL
Use this function to pre-load pellets for a period of 90 seconds when the stove is switched off and cold. Press P1 button to start and P3 button to stop. The initial
load phase must be carried out 5-6 times in case of 12kW corner inserts. The initial load phase will be carried out also when the hopper gets completely empty
during insert normal operation. The auger tube empties completely and the LOAD INITIAL phase must be repeated.
Menu M9 – STATE STOVE
This function displays the current status of all the devices connected to the stove. A few examples are included in the following pages.
Menu M10 – SETTINGS TECHNIC
This menu item is reserved to the stove installer. After entering the password, P2 (increase) and P1 (decrease) buttons allow all the stove working parameters to
be set.
USER FUNCTIONS
Standard functioning of a control board properly installed on a forced air pellet 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.
The technical setting mode is described in detail in the following sections.
Switch on the stove
To turn on the stove, turn on P3 for a few seconds. The ignition is signaled in the display
Start-up phase
The stove performs all the steps of the start-up phase according to the parameters concerning its levels and times.
Ignition failure
The alarm is triggered when, after the period of time set by Pr01, the fume temperature has not reached the minimum value admitted (Pr13 parameter) with a
gradient equal to 2°C/min.
Working mode
At the end of the start-up phase, if no problems occurred, the stove enters its normal WORK mode.
Exchangers are enabled if the fume temperature is higher than Pr15. Exchangers no.2 and 3 start working only if they were previously enabled.
Changing set room temperature
Press P1 and P2 buttons to change the room temperature. The display shows the current SET temperature value.
External thermostat/programmable thermostat
If you want to use an external programmable thermostat, connect it to the TERM clamps (connector CN7 pin 7-8).
• external thermostat: set the stove SET temperature to 7°C.
• external programmable thermostat: set the stove SET temperature to 7°C and disable the chrono functions from 03-01 menu.
The stove external thermostat is enabled when the contact is closed with stove on.
Room temperature reaches set value (SET temperature)
When the set room temperature value is reached or the fume temperature has reached the Pr13 value, the stove heat output is set automatically to the minimum
value (MODULAT-) mode.
If the stove is in the MODE STAND-BY mode, it switches off after the period of time set by Pr44 and after reaching the SET temperature. If the following condition
occurs -
T
ambiente >
(T
SET
+ Pr43), it is then possible to switch the stove back on.
Burn pot cleaning
When the stove is in the WORK mode, the “CLEANING FIRE-POT” mode is activated for the period set by Pr12 parameter at the intervals set by Pr03 parameter.
Stove switching off
Hold P3 button down for approx. 2 seconds to switch off the stove. The Auger tube stops immediately and the exhaust blower reaches its maximum speed value.
The CLEANING FINAL phase is performed. At the end of the period of time set by Pr39, when the fume temperature has reached a value below Pr13 parameter,
the exhaust blower stops.
Switching on the stove again
It will be possible to switch the stove back on only at the end of the safety period of time set by Pr38 and if the fume temperature has reached a value below
Pr13.
WHAT HAPPENS IN CASE OF…
Pellet ignition failure
If pellets do not ignite, the display shows the alarm message “NO LIGHTIN-”.
Power outage
When the power is resumed after an outage, the stove enters the CLEANING FINAL/BLACK OUT phase and waits until the fume temperature reaches a value
below Pr13.
If the power outage duration is longer than T, the stove switches off.
ALARMS
In case of malfunctioning the control board reports the problem and activates various procedures depending on the type of alarm. Possible alarm messages are
listed below.
In case of alarm, the stove is immediately switched off.
The alarm status is reached after a set period of time (Pr11) and can be cleared by pressing P3 button.
ALARM ACTIVE PROBE EXHAUST - Fume temperature sensor alarm
The alarm is triggered when the fume temperature sensor is not working properly or is disconnected. During the alarm, the stove switches off.
ALARM ACTIVE HOT EXHAUST - Fume overheating alarm
The alarm is triggered when the fume sensor registers a temperature exceeding 220°C. The stove switching-off phase starts immediately.
