    Staefa Controls

    I've inherited a building with some older Staefa stand alone controls and can't find anything on the web to help me decipher how they operate. I mean I get the gist, MA controller, min OA, DX Cooling. Since I can't find replacement controls without charging the customer a small fortune, I want to be proactive and find alternatives before they quit on me. Any info on the following would be appreciated:
    PU-K4
    RDK9
    RDK92
    SE4TV
    FR-T30
    FK-T30
    R.U22 (SCS-unico)
    Thanks in advance for any and all help.

    I can send you a scanned in staefa service manual that has all that kit except the R.U22 but its 12Mb. Stick your email address in your profile and I can send it later today.

    That would be awesome! I'll have to do it after work and when I get home, the internet on my phone doesn't let me edit my own profile. Thank you!

    SCS-Unico

    For others reference, it is a room temp sensor with integral controller.

    PDF attached.

    To Picnik or 501 miller, is there any chance I could get a copy of that staefa service manual, I do work in a library that uses that system, as with 501 info is hard to come by, I would greatly appreciate it.

    Thanks Stan

    The problem you will run into if a lot of those parts fails is that there is no viable replacement for a lot of it. The PU-K4, RDK92, SE4TV and RDK9 are 20V phase cut. The T-30s can be swapped out with 3.5K sensors that you can find. The FR-T30 can be swapped to 1Ks if they are on a universal input.

    neilh20man, you have to update your info and include an email address in it. You will be unable to post your email in the thread. I will send the info, but please add your email into your profile.
