Hi guys,
I am cleaning and rebuilding a complete IHKA heater system. I can measure the temp sensors but I do not know how to test the actuators. Anyone have any idea?
Here is a training manual IHKA in German language, I assume you can read and understand that, hope that helps, download it, Seminararbeitsmaterial IHKA 53 pages http://www.e38.org/e32/klimaautomatik.pdf
