Ämne: ES3 World Computer radiators not working after power shutdown

[Juan]

Hi all, apologies for the english.
I have an ES3 world computer at home, recently one of our fuses went out and after I changed it, seems like the settings on my heating system got reset and now my radiators aren't working. I managed to get the water to warm up so at least that's work.

I went through the Manual https://www.thorenvarmepumpar.se/images/Pdf-er/handbok_thor_es-3_till_2010.pdf and i couldn't find anything useful.

Does anyone have a hint into what can be going wrong?

Thanks in advance

It can be in the summer-mode.
Check outdoor temperature and the LED lamp for summer button?
There are also a changeover valve to shift between heating radiators or heating warm water, this can be broken?

Hi, thanks for the reply. Is not in summer mode. Is there any way I can check if the changeover from heating radiator to warm water is broken? or any indicator that this isn't working?

You can remove the engine part of the changeover valve, nr 3 in side 16 in your manual.
Depending on what type of valve it is you can try to move the valve position manually?
You can also check if the engine part moves if you switch between summer mode and not summer mode?
