Setting use of room thermostat (TA) where there is Open-
Therm (OT) connection
0 = Uses only OT communication. The heat request and the
setpoint are communicated only via OpenTherm.
1 = Uses room thermostat (TA) to activate heat request and
OT to communicate the setpoint requested to the boiler
(*).
(*) When setting parameter = 1 in a central heating system
managed with zone valves, where there is an OT room
thermostat for each valve, the OT room thermostat will
control the opening and closing of the respective valve
(zone) and the valve microswitch, connected to terminal
TA of the boiler, will control (ON/OFF) the heat request. If
both requests (OT and TA) are active, the OT request will be
fulfilled.

Direct Zone/Zone 1 setpoint in heating mode Par. 2001= 0
and 3
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 1 is configured as mixed, the value set in parame-
ter 1112 will be used as setpoint
If Zone 1 is not
enabled:

Direct Zone/Zone 1 minimum external temperature
It defines the minimum external temperature to which
the heating maximum setpoint in Par. 2119 must be asso-
ciated
-20…5 -20 °C I
2000 2121
Direct Zone/Zone 1 heating setpoint at the maximum ex-
ternal temperature (Par. 2122)
It sets the minimum heating setpoint when the external
temperature is equal to the value set in parameter 2122
(basic external temperature)
If Zone 1 is not
enabled:

Direct Zone/Zone 1 maximum external temperature
It sets the external temperature at which the boiler set-
point must be reduced, according to the value defined in
parameter 2121

2000 2125
Direct Zone/Zone 1 summer/winter switching
It stops the request in heating mode when the external
temperature is higher than this setpoint

Direct Zone/Zone 1 ambient temperature nominal value
When an OpenTherm (OT) ambient thermostat is connect-
ed to the thermal unit or to the zone control accessory,
this parameter is not displayed

2000 2133
Direct Zone/Zone 1 setpoint night reduction in heating
mode Par. 2001= 2 or 3
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.
