I talk to Auber all the time and will see what we can do about a payback
I have read the pdf referred to earlier and am reposting this pic that Jan posted earlier:
The thread size on the Auber RTD is M12 x 1 . While that is certainly a valid size, the 1.0 mm pitch is a very rare item. So, while removing piece A in the pic is relatively easy, be a little careful with piece B. The male thread on piece B would need to be M12 x 1 for a proper RTD fit. Call me a "doubting thomas" as I will believe it when I see it. Pics from you will be appreciated.
The female threads in piece B obviously accept the Prodigy thermostat bulb just fine. I do believe
those threads are (as I said in a previous post) PG 7 threads which would have a metric designation of M12.5 x 1.27 .
