<font size="4">For <span style="color:rgb(51,51,255)">Tcool =

24 °C?<br>
<br>
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.<br>
Furthermore, when I create another Tcool equation as <span style="color:rgb(51,51,255)">35*winter+24*summer</span>, the
result is also like the Attached On-Line Plotter image.<br>
<br>
Please give me some solutions or advices! <br>
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 </font><font size="4">(Tset=17 °C). I guess Maybe </font><font size="4">the
Mechanical Ventilation will influence on Cooling and heating?</font><br>

I make a simulation. The cooling set temperature is
24*Summer schedule (2162 h to 6552 h), The heating set
temperature is 21*Winter schedule (the rest hours).
After running, however, it appears WEIRD phenomenon.
Please see the ATTACHED Energy_zone.BAL file. During the
winter period, there are Qcools and Qcool is very large
up to 47000 kJ. And then it results in wrong BAL_ENERG,
it is not 0.<br>

I cant make type673 heating mode to work. Cooling mode
