The increase in space temperature in zones 2A and 5 in the LVEA this morning appears to be from sun exposure on the building. Both zones experienced rapid increases at the same time, at the same rate of increase. Both zones have the most sun exposure during the morning hours. The space sensors are located in the exterior walls which makes them susceptible to radiant heating during periods of direct sun exposure. These sensor locations also caused issues at the mid and end stations, when the southern exposures routinely read colder when the winds blow. 

I have made slight adjustments to the set points in zones 2A and 5 to accommodate for the sun exposure. If it continues to be a problem, sensor relocation will likely be needed.
