Hello guys:

I'm having trouble with a VVT Carrier zone controller M/N:33ZCVVTZC,thewre is RTU on roof that serves 6 classrooms with an individual space sensor per classroom, this one room is turning the heat on for no reason, teacher complains that is way too hot,space sensor reads 11.5 ohms@75F S/A sensor is also readind 11.6 @75F, both sensors are within range, the only other component that could mulfunctioning is the controller itself, its getting 24 V A/C, I also looked at the trend chart and is fluctuating up and down quite often, should I replace the controllers??? is there a way to troubleshoot it???. Thank you for any advice.
