SZVAV Sequence of Operation
Cooling:
Unit will look at zone sensor space temp input, set-point, and rate of fall. The unit will use this information in an algorithm to calculate a discharge air set-point. This is not a user controlled set-point, but can be altered by the DA Cool set-point limit being set to high or the zone sensor location receiving incorrect space temperature or incorrect information from the Discharge temp sensor. The unit is monitoring performance to help reduce unnecessary capacity run time. The unit will vary the compressor and indoor fan capacity to meet the discharge temp set-point.
