This warning is usually caused by a pump running when coils are off. The pump heat causes the plant water to heat up without a sink (the coils) for heat transfer. Check the operation of the coils with respect to pump operation. You can also add Output:Diagnostics, ReportDuringWarmup; to see what is happening if this warning happens before normal reports are generated.
