Heating general settings
2000 2001
Heating operating mode
0 = Operation with fixed setpoint and ambient ther-
mostat
1 = Operation with climatic curve and ambient ther-
mostat
2 = Continuous operation with climatic curve and
night reduction with ambient thermostat
3 = Continuous operation with fixed setpoint and
night reduction with ambient thermostat
4 = Operation with variable setpoint with input signal

2000 2007 Switch-off hysteresis in heating mode 0…20 3 °C I
2000 2008 Ignition hysteresis in heating mode 0…20 3 °C I
2000 2005 Circulator post-circulating time in heating mode 10…900 120 sec I
2000 2009
Burner restart time
It defines the stand-by time for a subsequent restart
after a switch-off, regardless of the delivery temper-
ature decrease. If it goes below the value set in Par.
2010 the thermal unit remains on.
10...900 180 sec I
2000 2010
Temperature differential for burner restart
It defines the temperature difference below which
the burner restarts regardless of the elapsed time
indicated in Par. 2009.

2000 2096
Overtemperature protection
If the boiler temperature exceeds this value, the
burner turns off and the circulator continues its op-
eration to discharge the excessive heat.
85...95 85 °C I
Direct Zone / Zone 1 Heating Settings
3000 3100
Use of Zone 1 control accessory
0 = NO
1 = Yes
If Zone 1 control accessory is used, AT and AP inputs
are not enabled. AT input is used only to enable the
night reduction on all the active zones (Par. 2001 = 2
and 3)
0…1 0 I

0 = direct
1 = mixed
0…1 1 I

Direct Zone/Zone 1 setpoint in heating mode Par.
2001= 0 and 3
The thermal unit adjustment determines the boiler
setpoint in heating mode, using the highest value
among the requests of all the active zones (Par. 1101,
1201, 1301)
If Zone 1 is configured as mixed, the value set in pa-
rameter 1112 will be used as setpoint
If Zone 1 is not ena-
bled:
(Par. 2121, Par. 2024)
If Zone 1 is enabled:
BT: (Par. 2121, 45)
