Issue overview

User file has PTACs with hot water heating coils. PTACs provide ventilation air. For zones with a zero design zone heating load, the PTAC heating coil is undersized and cannot temper the ventilation load. Adding a small negative other equipment load to those zones in order to force a non-zero design heating load fixes the coil sizing. Unit 116 and Unit 206 show the problem.
