Help with Flat Plate Solar Collector temperature out of range errors (too high and too low)

edit

I am trying to use the SolarCollector:FlatPlate object in EnergyPlus to reduce the load on the boiler to provide heat for my space and swimming pool. I'm unfamiliar with this object and I don't know how to set it up correctly. I have read through the E+ documentation on the object, and I have looked through the example file for the object but I am still getting the following warnings in my simulation.

** Warning ** GetSpecificHeatGlycol: Temperature is out of range (too high) for fluid [WATER] specific heat **
**   ~~~   ** ..Called From:UpdatePlantLoopInterface,Temperature=[198.57], supplied data range=[0.00,125.00]

I can't figure out what is causing the the temperature to be too high or too low. I have tried raising and lowering the flow rate of the water through the plate, but that did not solve the problem.

I am grateful for any ideas.
