Zone 2 minimum heating setpoint at basic external
temperature (Par. 2222)
It sets the minimum heating setpoint when the
external temperature is equal to the value set in
parameter 2222 (basic external temperature).

2000 2220
Zone 2 minimum external temperature
It defines the minimum external temperature to
which the maximum heating setpoint Par. 2219 must
be associated.

2000 2222
Zone 2 basic external temperature
It sets the external temperature at which the boiler
setpoint must be reduced, according to the value de-
fined in parameter 2221.

Zone 2 summer/winter switching
It blocks the heating request when the external tem-
perature is greater than this setpoint.

Use of Zone 3 control accessory
0 = NO
1 = Yes
If Zone 3 control accessory is used, AT and OT inputs
are not enabled. AT input is used only to enable the
night reduction on all the active zones (Par. 2001 = 2
and 3).

2000 2303
Zone 3 heating setpoint in 0 and 3 heating modes
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 3 is configured as mixed, the value set in
parameter 1114 will be used as setpoint.
