I am modeling central AHUs w/chilled water cooling coils and hot water
reheat at the zone level.
I can export hourly data from the system reports for the return air
temperature, entering coil temp, leaving coil temp, etc. BUT I was
wondering if there is a way that I can verify the supply air temp after
the reheat coil?
When I export the Zone Unit-Supply temp form the variable type: Thermal
Zone, I get zeros!! Am I looking in the wrong place or is there a reason
why we can not get the supply temperature after the reheat coil? I
appreciate any input. Thanks!

Michelle,
I've had the same problem in trying to get the supply air temp after the reheat coil in eQUEST. As far as I can tell, it can't be done. I believe the reason why you are getting zeroes with the Zone Unit-Supply Temp under the Thermal Zone is due to the fact that the system type you have selected doesn't have a "Zone Unit". Even though there are reheat coils in the zone, it doesn't classify that as an unit, which makes sense considering you have a central AHU. Other system types have "Zone Units", like unit heater, fan coil, etc.
Sorry I couldn't help, maybe someone out there knows a way of getting supply air temp after reheat?
