the way i understand it (and my electrical knowledge is fairly limited, so i may be misinterpreting it) is that the hot wire is what is being switched. so I have my input hot wire connected to channels 1, 5, & 7 (all pigtailed from the channels wire nutted together with the hot from the power cable, so 4 wires total). this hot is interrupted by a switch in both the heat/cool stages, so channels 6 and 8 each feed a separate hot wire to the receptacle to control the fridge/heater. the neutral from the power cord is in connected to the receptacle and no, i did not break the tab on the neutral side which takes care of neutral on both outlets. i have a jumper neutral that feeds the controller. since only the hot is switched, the neutral stays live to control whatever it needs to.
hopefully that makes sense. and hopefully that isn't the wrong way to do it, but it seems to work fine as is. let me know if that answers your question.
