Or sorry, I made a mistake in my previous mail :
* Tcool = 35 - 9 * Summer (instead of 35*winter - 9*summer)
Regarding your heating system it may be something like :
* Theat = 21*Winter
Regarding your attached picture, your heating system seems to work all
the time.
In summer, either you cool at 21°C, either there is no internal gains
defined, and you heat at 21°C.
Check your differents inputs.
You can procede step by step (internal gain = 0, ventilation = 0,
infiltration rate = 0...) to see the influence of each parameters in
your model to catch your issue.
Best regards
