The "Comp. T. @ T.ext. Max" parameter, if other than 0, trans-
forms the climatic curve from linear to quadratic allowing you to
best adapt the variation of the setpoint to the variation of the
outdoor temperature.
The resulting quadratic climatic curve will have three parame-
ters:
− Heat. Set. Max
− Baseline Outdoor Temp.
− Text. Min
of the basic linear climatic curve and a value of the Heat. Set.

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.
To activate zone programming:
°C Menu → "Settings" → "Time Config."
