Zone 3 basic external temperature
It sets the external temperature at which the boiler
setpoint must be reduced, according to the value de-
fined in parameter 2321.
5...30 20 °C I
2000 2325
Zone 3 summer/winter switching
It blocks the heating request when the external tem-
perature is greater than this setpoint.

2000 2331 Zone 3 mild climate temperature compensation 0...20 0 °C I
2000 2332
Zone 3 ambient temperature nominal value
When an OpenTherm (OT) ambient thermostat is con-
nected to the zone control accessory, this parameter
is not used.

DHW settings and system configuration
2000 2047 DHW setpoint with heater 40...65 57 °C U
2000 2036
Hysteresis for heater DHW request start
If the heater temperature goes below the DHW
setpoint minus the hysteresis value defined in this
parameter, the regulator confirms the fulfilment of
the request.
0...20 3 °C I
2000 2037
Hysteresis for heater DHW request stop
If the heater temperature goes above the DHW
setpoint plus the hysteresis value defined in this
parameter, the regulator confirms the stop of the
request.
0...20 3 °C I
2000 2038
Thermal unit delivery temperature increase in DHW
mode with heater
It increases the delivery temperature to the boiler by
the value set in this parameter.
0...30 15 °C I
2000 2042
Heat request priority
0 = Time priority between domestic and heating
mode defined by Par. 2043.
1 = Heating mode priority
2 = Domestic mode priority
0...2 2 I
2000 2043
Time for which the priority is alternately assigned to
domestic and heating circuits when the Par. 2042 is
set to "0” mode (for heater only).
