Comp. Parameter T. @ T.ext. Max
During in-between seasons, when the external temperature
gets close to the maximum limit set (T. Ext. Max.), the delivery
temperature calculated in the climatic curve could be different
from the one suitable to meet the request. This parameter per-
forms a non-linear correction of climatic curve to compensate
such difference.

6.5 Programming the zone
By default the schedule timer is disabled.
In fact, to start a request from the zone just close the contact
of the zone request. In this case the thermal module (or the
cascade of thermal modules) will start with a setpoint equal to
the value calculated on the zone climatic curve increased by the
"Zone Extra Setpoint" value and the mix valve will modulate to
maintain the delivery temperature of the zone at the calculated
setpoint.
If there is no external sensor, the delivery setpoint of the ther-
mal unit will be equal to the maximum setpoint of the climatic
curve.
