The functions with 0...10V regulator are activated by means of their parameters. When the function is enabled (P82=3)
and P78=1, the input manages the heating set point temperature directly; when P78=2, the input manages the heating
power input directly. Demand is activated above 3V and the heating setpoint is calculated in proportion to deviation from 3
to 10 V DC, to give a setpoint that goes from minimum to maximum.
