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.
− T. Out. Min
of the basic linear climatic curve and a value of the Heat. Set.
Min. diminished by the value of the parameter "Comp. T. @
T.ext. Max", as can be seen in the example in the figure.

When more than one direct zone activates a heat request
at the same time, the delivery setpoint will be equal to the
highest setpoint of the zones making the request.

To set the direct zone with a fixed setpoint, the zone setpoint
values "Max. Set. CH" and "Min. Set. CH" must be equal.

5.6 Programming the zone
By default the schedule timer is disabled.
To start up a request from the zone, just close the zone request
contact. In that event the thermal unit (or the cascade of ther-
mal units) will start up with a setpoint equal to the value cal-
culated on the zone climatic curve increased by the "Zone Ex-
tra Setpoint" value and, if it is a mixed zone, the mix valve will
modulate to maintain the delivery temperature of the zone at
the setpoint calculated.
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.
