Hello,

I write in English because I do not speak German language.
I had the same problem with valve thermal drive control A2T4-SAUTER.
CTC build it in some of their boilers as a part of automatic heating control
CRC-matic typ EW-3.
I have CTC central heating boiler type EM-265.
This is the third control that has got out of order. Each control lasted cca 5 years. Now you can not purchase a new one because they are not produced any more. No alternative solution is foreseen.
What a shame for CTC.
CTC boiler is of a good quality, and it will still last for many years.

Here is information for you.
I have found technical solution how to repair-change A2T4 thermal membrane.
People with the same problem can contact me.
They will get repair information gratis (text and fotos).
Change part is cheap and reliable (Danfoss).

With kind regards
