2577 : // The available capacity of the desuperheater heating coil is determined by the

2580 : // a requested load (load based control) or applied to the air stream to meet a
2581 : // heating setpoint (temperature based control). This subroutine is similar to
2582 : // the electric or gas heating coil except that the NominalCapacity is variable
