Dear Mr. Chehal,<br>I think that the problem can be in the fact that if the room have a Tint fixed to 26°C, your equation don't consider this case. Perhaps is sufficient to change the equation in the following form:<br>
<p align="left"><span lang="en-us"><font face="Arial" size="2">Output</font></span><span lang="fr"></span><span lang="en-us"> <font face="Arial" size="2">= lt(time,2880)*16735 + ge(time,2881)*le(time,6552)</font></span><span lang="fr">
</span><span lang="en-us"><font face="Arial" size="2">*( lt(Tint,26)*16735+g<font size="6">e</font>(Tint,26)*33470 )</font></span><span lang="fr"></span><span lang="en-us"> <font face="Arial" size="2">+ gt(time,6553)*16735
</font></span></p><span lang="en-us"><font face="Arial" size="2"></font></span>Hoping to be helpful I wish you success in your work anyway,<br>Best regards,<br>Michele Liziero<br><br>-- <br>Ing. Michele Liziero<br>Politecnico di Milano - Dipartimento di Energetica
