If you have 5 zones served by this unit, you will note from the tree diagram to the left (after clicking Air Side at the top) that the unit requires a Control Zone. That is where the thermostat will be (just like a real house). That zone will be satisfied. The others may or may not be, depending on the extremes in load.</span></div><div id="yui_3_16_0_ym19_1_1471191826377_4125" dir="ltr"><span><br></span></div><div id="yui_3_16_0_ym19_1_1471191826377_4125" dir="ltr"><span id="yui_3_16_0_ym19_1_1471191826377_4414">When you put a DX package in each space, you have now given each space a thermostat, and thus each t-stat will control its own zone.</span></div><div id="yui_3_16_0_ym19_1_1471191826377_4125" dir="ltr"><span><br></span></div><div id="yui_3_16_0_ym19_1_1471191826377_4125" dir="ltr"><span>John R.
