I'm getting severe error when using single speed cooling tower which terminates the run. I'm not getting this error when using 2-speed and variable speed cooling towers. All auto sizable fields were left as autosized for all 3 types of towers but I'm getting errors only when using the single speed tower. Also, the edit tab for the single speed cooling tower shows grayed out fields (cannot be edited). Is there a way to make this fields editable?
Below is the error message I'm getting:
* Severe * CoolingTower:SingleSpeed "1 SPD COOLING TOWER". Tower performance input method requires valid nominal capacity.
* Severe * CoolingTower:SingleSpeed "1 SPD COOLING TOWER". Nominal tower capacity has been specified and design tower UA is being autosized.
* ~~~ * Design tower UA field must be left blank when nominal tower capacity input method is used.
* Severe * CoolingTower:SingleSpeed "1 SPD COOLING TOWER". Nominal capacity input method has been specified and free convection UA is being autosized.
* ~~~ * Free convection UA should be left blank when nominal tower capacity input method is used.
* Severe * CoolingTower:SingleSpeed "1 SPD COOLING TOWER". Free convection nominal capacity must be less than the nominal (design) tower capacity.
* Fatal * Errors found in getting cooling tower input. ...Summary of Errors that led to program termination: ..... Reference severe error count=4 ..... Last severe error=CoolingTower:SingleSpeed "1 SPD COOLING TOWER". Free convection nominal capacity must be less than the nominal (design) tower capacity.
I'm testing this on a simple model to isolate the error and get quick results. Nominal capacity can't be entered manually as the field and others are grayed out. Any comment on why this error is occurring or suggestions to correct this error will be most appreciated. Thanks.
