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.
