[EnergyPlus_Support] Water-to-Air Heatpump and Humidity Control

["energyplus99" <energyplus99@xxxxxxxxx>]

I have a water-to-air heatpump(using coefficients) hooked up to a 
vertical GSHE and three zones.  One zone has a thermostat and I am 
able to nicely control the temperature through that thermostat via a 
dual setpoint with deadband.

But during a summer designday run the humidity gets really high.  So 
I added a ZONE CONTROL:HUMIDISTAT to the zone containing the 
thermostat and now I get the following severe error:

"DualSetPointWithDeadBand: Effective heating set-point higher than 
effective cooling set-point"

How is it that the setpoints that I specified are changed (I've 
checked the values and what I specified looks OK)?  And what can I do 
to remedy the situation? (The error message suggests that I increase 
the deadband if Im using an unmixed air model - but Im using the 
default model so I dont think the suggestion is relevant).

Any help would be greatly appreciated!
