Tekmar D352 help!

Mich Member Posts: 1
I've bought a house with radiant in-floor heating controlled by a Tekmar house control D352.  My floors become HOT wherever the system is turned on.  I have read the error messages in the manual, none of which reflect what my panel is showing...all of the indicator lights are on and none of them are blinking!  Apparently the 352 has been discontinued and no one in my area seems to know what to do about my way too hot floor.  Does anyone have some advice?

    Hi Mich,

    You can find the manual for your Tekmar on their website. You should be able to download it as a pdf. file, and make a hard copy. Good Luck!

    I have a Tekmar 352 controlled system, so I can help if you still are looking for information.

    you might have

    a bad injection zone valve. If memory serves the 352 does on/off injection.

    would need more detail about what's going on and what you have for a system here.
