Hello. I am new to pellet burners.
I just bought a Variowin with a B-PML buffer loading module. My problem is the apparent total lack of schematics to show what pumps and valves I need to make this run and load the buffer.
I could buy the windhager solution at 1000£ for 2 pumps and a master controller but would prefer to understand how this thing works and use my own OpenMotics house control system to run the boiler.
Can anyone point me to the plumbing and electrical connection schematics to set this thing up?
