to cooling mode and the controller in this case is iterative feedback controller ?</div><div>thanks </div><div style="font-family: arial, helvetica, sans-serif; font-size: 12pt; "> <span class="Apple-style-span" style="font-family: tahoma, 'new york', times, serif; font-size: small; ">------</span></div><div style="font-family: arial, helvetica, sans-serif; font-size: 12pt; "><font face="tahoma, 'new york', times, serif" size="2">Best </font><font class="Apple-style-span" face="tahoma, 'new york', times, serif" size="2">Regards</font></div><div style="font-family: arial, helvetica, sans-serif; font-size: 12pt; "><font face="tahoma, 'new york', times, serif" size="2">Ayman Mohamed</font></div><div><font class="Apple-style-span" face="tahoma, 'new york', times, serif" size="2"><br></font></div></div></body></html>
