The heating curve is set when the installation is commissioned,
thermostatic valves open if necessary. In event of major losses from the
building, it is necessary to adjust the gradient of the curve mid-season
then mid-winter in increments of 0.1 every 24 hours (building inertia).
To set the heating curve for a zone:

4. With the Custom notification notification type, set the number of
operating hours before a maintenance message is sent:
1. Follow the access path described below.
2. Select the value that corresponds to the type of circuit selected:
1. Select the icon for the zone to be modified;
2. Select Heating Curve.
3. Set the following parameters:
Description
Value for the heating curve gradient:
underfloor heating circuit: gradient between 0.4 and 0.7
radiator circuit: gradient of approx. 1.5
Maximum temperature of the circuit
Curve base point temperature (default value: Off = auto­
matic mode).
If Base: Off, the curve base point temperature becomes
equal to the room set point temperature
Water temperature in the circuit for an outdoor tempera­
ture. This data is visible all along the curve.
