Configurable (default: disabled)
Only for INDIG3: PWM input (100Hz/0,03Hz) to check the %
value of power which depends on the cycle; this function lets
you to set a power set point by means of a digital signal (ex.
from PLC or controller with PWM output).

OUTPUTS
Configurable (default: heat control)
State of control is displayed by LED (O1, ,O3)
OUT1 is connected to Master unit,
OUT2 and OUT3 are connected to Expansion units
