Hello,
Does anyone knows how the hardware (and software) of a regulator to start modulating the gasburner of central heating works.
I mean modulating on the boilers own thermostate (set on 60°C).
The boiler measuring points are suction and return temperature.
The signal to start modulating go to the boilerfan speedregulator with on his turn regulate the gasvalve and this mixture goes through a venturi ad the premix burner.
Thanks in advance
Albert
