The “Comp. T. @ T.ext. Max” parameter, if other than 0, transforms
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 parameters:
- Heat. Set. Max
- Baseline Outdoor Temp.
- Text. 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.

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 ther-
mal 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.
