Zone 2 setpoint increase
Increases the value of the heating zone setpoint. For
example, if the zone setpoint is 40°C, the heat request
sent to the boiler will be increased by 5°C (factory setting),
therefore the value requested at the boiler will be 45°C.
Valid only for mixed zone.

If Zone 2 control accessory is used, AT and OT inputs are not
enabled. AT input is used only to enable the night reduc-
tion on all the active zones (Par. 2001= 2 and 3)

Zone 3 Heating Settings

Zone 3 heating setpoint in 0 and 3 heating modes
The thermal unit adjustment determines the boiler set-
point in heating mode, using the highest value among
the requests of all the active zones (Par. 1101, 1201, 1301)
If Zone 3 is set as mixed, the value set in parameter 1312
will be used as the setpoint.

Zone 3 setpoint night reduction in heating mode (Par. 2001

It defines by how many degrees the heating setpoint will
be reduced at the opening of the ambient thermostat (AT)
contact
The reduction of the delivery temperature affects all the
active heating zones and it can be used when the AT ter-
minal of every zone regulator is jumpered
