7.5.1. MODIFYING THE WATER TEMPERATURE SETTING

Description
To modify the water temperature, press button P1 and
then increase or decrease the temperature parameter
with buttons P1 and P2.
When the water temperature has reached the set value,
the power is automatically brought to the min. value,
MODULATION status.
When the fume temperature reaches a set max. value the message MODULATE F appears
on the control panel and the stove activates the flame modulation procedure without
any user intervention, whereas if the temperature exceeds 285°C the alarm "AL3 HOT
FUMES" appears and the boiler activates the shutdown procedure.

7.5.2. CLEANING THE BRAZIER

Description
During normal operation in work mode, the "BRAZIER
CLEANING" mode is activated at parameter-fixed
intervals for a set duration.

7.5.3. DHW WITH RAPID HEAT EXCHANGER

Description
When hot water is required, the display shows the message DHW EXCH and the LED
indicated by the tap lights up. The function is carried out only if the boiler is on, and the
water inside the heating chamber has reached a sufficient temperature. In the remaining
cases the service is not provided.

7.5.4. DHW WITH STORAGE TANK

Description
This type of installation requires the use of an external thermostat or a water probe, which
measures the DHW storage tank (puffer) temperature.
▪ In the former case, temperature SETTING is obtained by adjusting the puffer thermostat
controller.
▪ In the latter case, to modify the temperature it is necessary to press button P2 on the
control panel and then increase or decrease the temperature value with buttons P1 and
P2.
The DHW function is activated when the temperature falls below the SET temperature.
During the STANDBY phase, the boiler automatically lights and goes to WORK mode.
Once the work temperature of the heating chamber water is reached, the supply of water
to the storage tank (puffer) is activated. The boiler display shows the message DHW and
the respective LED lights up.
When the SET temperature of the storage tank is satisfied, the BOILER activates the
heating system.
