6.1.2 Heating curve
The following menu allows you to select the heating curve (value
adjustable between 0.2 and 4 - factory setting: 0.5), which allows
you to obtain the maximum heating demand for the usual minimum
outdoor temperature for the region in which the sensor is installed.
The automatic heating curve function continually and automatically
seeks the most suitable value to ensure your comfort and
the effi ciency of your heating system. The optimum value is
obtained approximately 24 hours after the system is started. It is
recommended to activate this function.
1 Select Htg curve settings
on the screen.
2A With Automatic htg curve
activated.
2B With the Automatic htg
curve deactivated, you must

Case of a heat pump controlled by On/Off contact
• Refer to the heat pump installation manual to access the
“after-sales” parameters listed below.
• Set the heat pump heating curves complying with the
correspondences with the Systempro control unit heating
curves (see table below).
b
Incorrectly setting these parameters may signifi cantly
impact the system effi ciency.
- Setting of the heat pump parameter 112:
Heating curve of the Systempro
control unit
Heating curve
of the heat pump
0.1 ▸ 02 7
0.3 ▸ 0.4 8
0.5 ▸ 0.7 9
0.8 ▸ 0.9 10
1.0 ▸ 1.2 11
1.3 ▸ Max. 12
Example:
- Setting of the heat pump parameter 112:
Heating curve of the Systempro
control unit
Heating curve
of the heat pump
0.1 ▸ 0.2 7
0.3 ▸ 0.4 8
0.5 ▸ 0.7 9
0.8 ▸ 0.9 10
1.0 ▸ 1.2 11
1.3 ▸ Max. 12
In the case where the MODUZONE Z20 or Z30 option is installed:
if the curve setting is "1.2" on the control unit, the curve setting
will be "11" for heat pump parameter 112.
