[EnergyPlus_Support] Operation Scheme Error

["JV Dirkes II" <jvd2pe@xxxxxxx>]

Dear E+ Forum,

I have not been able to fix the error below, and will appreciate some
insight and help.  There is only one "Plant Operation Schemes" object
in the .idf (as shown below), so I can't figure out what the error
refers to.



   ** Severe  ** More than one Operation scheme scheduled for same
plant loop
   **   ~~~   ** occurs in PLANT LOOP = PLTLOOP_HTGWATER
   **  Fatal  ** Program terminates due to above conditions.
