They went bust, no idea how, but anyhow, I have a Navitron tdc3 solar therm
al controler and some years ago I saw someone explain in great detail exact
ly how the special functions, like speed control, worked. Is anyone here a
refugee also and has tucked away in their Dropbox Onedrive or filing cabine
t somewhere this explanation? Or can help me out with exactly how it works?
The instructions in the manual are not very good and still have not evolve
d for the latest models(made by Sorel)
