Work Phase - Ferroli LIRA SLIM PLUS Use, Installation And Maintenance Instructions

LIRA SLIM PLUS

6.1.3. WORK PHASE

When the fume temperature reaches and exceeds the preset value and maintains it for at least a certain time, the
unit switches to work mode, displaying the message "heat" and the ON/OFF LED is on.
When the fume temperature reaches the preset threshold, the fan turns on (exchanger LED on).
During the work phase, brazier cleaning is activated at preset intervals, displayed by the message "Brazier clean"
for a set duration.
Changing the work output
During the work phase, it is possible to change the heating capacity by pressing the + button (set output LED on).
To increase output, press the + button again, to decrease it press the – button.
The set output level is shown on the display. Wait 10 seconds to exit the setting, without carrying out operations on
the keypad, or press the ON/OFF button.
Changing the room temperature
Press the – button to change the room temperature. The SET temperature is shown on the display and to change it
use the + (increase) and – (decrease) buttons. After about 10 seconds, the value is stored and the display returns
to normal viewing, or press ON/OFF to exit.
When the room temperature reaches the set value, the heating capacity of the unit decreases automatically until it
reaches its minimum value; in these conditions, the display shows the message "temp. Reached" and the LED on
the display comes on.
Standby
If enabled in the menu, this function allows the unit to be turned off under the conditions listed below:
- if the room temperature is higher than the setpoint plus a temperature gradient, the display will show the message
"start-standby" for a certain time, highlighting the time in minutes to activate the function.
After this time, the message "waiting" appears on the display; in this state, the auger is off (auger LED off), the room
fan switches off when the threshold is reached and the ON/OFF LED flashes.
When the fume temperature reaches the preset threshold, the unit goes on standby and the message "eco stop" is
displayed. The auger is off (auger LED off), the room fan is off (exchanger Led off) and also the fume fan.
If the room temperature drops below the set temperature (Room setting) minus the temperature gradient, the unit
turns on again.
Make sure to check the pellet level in the hopper to prevent the flame from going
out due to lack of pellets.
The lid of the pellet hopper must always remain closed, it must only be opened
when loading fuel.
The bags of pellets must be kept at least 1.5 m away from the unit.
If STANDBY mode is not activated and the SET temperature is reached, or if the fume temperature has reached the
maximum set value, the message MODULATE or MODULATE F appears on the display and the unit activates the
flame modulation procedure without any user intervention.
If, instead, the STANDBY mode is activated, when the SET temperature is reached the unit activates the modulation
mode for a few minutes. If the temperature remains steadily above the set point, the unit turns off. Restart occurs
after the room temperature drops below the set temperature by a few degrees (default 2 °C). If the fume temperature
increases further, beyond a set limit, the HOT FUMES alarm appears and the unit activates the shutdown procedure.
