Debugging of errors

I get this recurring error when I run my model. what could be the reason and how do I correct it?

CalcDoe2DXCoil: Coil:Cooling:DX:SingleSpeed="POINT_OF_SALE SZ-CAV COOLING COIL" - Air volume flow rate per watt of rated total cooling capacity is out of range error continues...

That warning means the DX cooling coil has an air volume flow rate about 2 times higher than expected.

The volume to capacity ratio for DX coils is DX coil volume air flow/DX coil cooling capacity.

The expected range is around 0.00004 - 0.00006 m3/s/W.

The coil air flow is too high or the coil capacity is too low.

Thank you so much for the clarification. How do you recommend I can correct the flow rate?

Increase the cooling capacity or decrease the air flow rate by 2x.
