OpenTherm --> Analog Converter
Posted: Tue Oct 25, 2016 2:47 pm
I have a Vaillant Aqua Plus (VUI 280-7) boiler that has an analog interface (pins 7-8-9) for flame modulation, so it expects a DC voltage range.
I would like to install a Honeywell Evohome system in my house that has an OpenTherm interface for flame modulation.
The boiler is still in a good shape, so no reason to replace it yet with a more modern one that has an OpenTherm interface, but instead it would be great if I could find an OpenTherm --> Analog converter that can be applied to my boiler.
Can anybody help me in this regards?
