In this case you would be guessing on aligning the schedules with weather so it probably wouldn't work that well. You could iterate on different changeover dates to try and get it right ... </DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Regards,</DIV><DIV>Graham</DIV><DIV><BR><DIV><DIV>On 22/06/2007, at 3:09 AM, Chris Jones wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"> <FONT face="Courier New, Courier" size="2">The typical market condo in downtown Toronto has a two-pipe fan coil with an electric coil for heating during the change over season.
