Help with Buderus 2107 Logamatic Control

Maximus

Hi there, I have a question regarding the Warm Weather Shutdown (WWSD) on my heating system, equipped with Buderus 2107 Logamatic Control.
Here is the problem, I set the WWSD temperature at 12 c° so the heating system should work only under this outside temperature and not over, but even with 15 c° the heating system doesn't enter in summer mode and start heating the house without any needs because in the rooms is more than 22 c°, so I go on the heating room and set manually the summer time.
There is something that I can check, for example a delta in temperature ?
Thanks

No ideas ?

If you know how to use a meter abd can download the control manual, you could check it out, otherwise you’re going to need someone familiar with that control to come over and start troubleshooting.

cold draft blowing on the OA sensor (?)

or sensor out of spec, does the boiler control show the OA temp?

I would check if the OD temp reading on the screen is the same as your setting. Check the OD sensor. When you set the control to summer does the issue go away?
