Unitary System Performance

I have successfully cloned a Unitary System from a component model into an airloop, and inserted a setpoint manager, air terminal, and zone. However, I have received an error that I am not sure how to resolve. The error message reads:

"Cooling coil object type requires valid UnitarySystemPerformance:Multispeed for cooling to be specified with number of speeds > 0"

If anyone has some pointers on what is the main issue, that would be great.
