[EnergyPlus_Support] Air to Air heatpump error

I keep getting the warnning

   ** Warning ** Coil:Cooling:DX:SingleSpeed "128376 COOLING COIL" - Full load outlet air dry-bulb temperature < 2C. This indicates the possibility of coil frost/freeze. Outlet temperature =   1.40 C.
   **   ~~~   **  ...Occurrence info = IBM  BARTON, 04/20 11:10 - 11:15
   **   ~~~   ** ... Possible reasons for low outlet air dry-bulb temperatures are: This DX coil
   **   ~~~   **    1) may have a low inlet air dry-bulb temperature. Inlet air temperature = 13.537 C.
   **   ~~~   **    2) may have a low air flow rate per watt of cooling capacity. Check inputs.

It appears to me that it is trying to cool when it should be heating (the return air temp is below set point).

Does anyone have any suggestions?
