The last week has seen the space temperature of the VEA at End X slowly increase during the morning hours. This was found to be associated with the outdoor air temperature reset programming which allowed the supply air temperature to reset upward as the temperature outside cooled off, which was most pronounced in the early morning hours. This rise in supply air temperature prevented the air handler from effectively cooling the space, until the sun came up and warmed the air, which caused a downward reset. This programming has been modified to avoid this problem in the future.
