<P>Hi Jon,</P>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; All the 3 loops are the "zone control",basic control exactly, and first loop for January~April, second loop for May~Oct,the third loop for the last two months.Each has different heat&amp;cool temp. Those loops are all for one zone. Can we link the loops to the zone at the same time?</P>
<P>&nbsp;</P>

&gt;The&nbsp;following&nbsp;question&nbsp;needs&nbsp;further&nbsp;clarification
&gt;
&gt;-&nbsp;are&nbsp;the&nbsp;3&nbsp;loops&nbsp;´zone&nbsp;controls´or&nbsp;´plant&nbsp;controls´?
&gt;-&nbsp;are&nbsp;all&nbsp;3&nbsp;loops&nbsp;active&nbsp;at&nbsp;the&nbsp;same&nbsp;instant&nbsp;in&nbsp;time?
&gt;-&nbsp;please&nbsp;describe&nbsp;each&nbsp;of&nbsp;the&nbsp;control&nbsp;loops&nbsp;-&nbsp;what&nbsp;is&nbsp;being&nbsp;sensed,&nbsp;what&nbsp;is&nbsp;being
&gt;&nbsp;&nbsp;actuated,&nbsp;what&nbsp;control&nbsp;logic&nbsp;is&nbsp;being&nbsp;used,&nbsp;how&nbsp;many&nbsp;periods&nbsp;in&nbsp;the&nbsp;day
&gt;&nbsp;&nbsp;and&nbsp;most&nbsp;important....
&gt;-&nbsp;what&nbsp;is&nbsp;the&nbsp;goal&nbsp;of&nbsp;the&nbsp;control?
&gt;
&gt;One&nbsp;zone&nbsp;can&nbsp;have&nbsp;one&nbsp;ideal&nbsp;control&nbsp;associated&nbsp;with&nbsp;it&nbsp;at&nbsp;each&nbsp;timestep.&nbsp;And
&gt;one&nbsp;physical&nbsp;room&nbsp;can&nbsp;be&nbsp;modelled&nbsp;as&nbsp;three&nbsp;thermal&nbsp;zones&nbsp;(e.g.&nbsp;perimeter,&nbsp;middle&nbsp;core)
&gt;each&nbsp;associated&nbsp;with&nbsp;a&nbsp;different&nbsp;control&nbsp;loop.

&gt;Hi&nbsp;all
&gt;
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I&nbsp;have&nbsp;set&nbsp;3&nbsp;loop&nbsp;for&nbsp;one&nbsp;year&nbsp;and&nbsp;i&nbsp;want&nbsp;to&nbsp;link&nbsp;all&nbsp;the&nbsp;3&nbsp;loops&nbsp;to&nbsp;the&nbsp;zone.&nbsp;But&nbsp;it&nbsp;seems&nbsp;one&nbsp;zone&nbsp;only&nbsp;can&nbsp;be&nbsp;linked&nbsp;with&nbsp;one&nbsp;loop.
&gt;
&gt;&nbsp;&nbsp;&nbsp;&nbsp;Is&nbsp;there&nbsp;any&nbsp;solution&nbsp;for&nbsp;the&nbsp;problem?
&gt;
&gt;Thanks,
&gt;Teresa
