I am out of the office from Monday, June 11 to Friday, June 15 and unable to respond at this time.
For any urgent matters, please contact Dr. Manuel Romero (manuel.romero_at_imdea.org).
Thank you for your understanding.

Dear Adrien Jezequel,
Many thanks!
I think you'd better put for cooling temperatures
- 35?C in winter (no cool) - heating temperature at 21?C
- 24?C in summer
which may be translated in an equation tool by something like :
- summer = GE(TIME,2162)*LT(TIME,6552)
- winter = 1 - summer
- Tcool = 35*Winter - 9*Summer
For Tcool = 35*Winter - 9*Summer, do you mean if in winter, Tcool = 35 ?C,
so Cooling doesn't work ; if in summer, Tcool = -9?C or 24 ?C?
Meanwhile, another weird phenomena appear: After running based on your
solution in winter, indoor temperature becomes 35 ?C also not 21 ?C,
although I set heating temperature as 21 ?C; in summer, however, indoor
temperature becomes 21 ?C. Please see the Attached On-Line Plotter image.
Furthermore, when I create another Tcool equation as 35*winter+24*summer,
the result is also like the Attached On-Line Plotter image.
Please give me some solutions or advices!
I think the point how to set that Cooling doesn't work in winter? The
possible reason of that problem is that I also set a Mechanical Ventilation
in winter (Tset=19 ?C) and summer (Tset=17 ?C). I guess Maybe the
Mechanical Ventilation will influence on Cooling and heating?
Many thanks in advance!

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
