What software are you using, Justin? I have seen EnergyPro require
the cooling tower minimum water temperature to be above the boiler
setpoint. This might be correct for a water source heat pump
system, but I don't think it is correct for a hot water reheat
system, for instance. I have never been able to get EnergySoft to
tell me why this limitation exists.<br>
<br>
You may have a different situation, but I have seen that error in
EnergyPro.<br>
