Hello All,

I am having some issues with cogeneration control. I have set up an equipment control schedule on a hot water loop that my cogeneration system is attached to but I can not select it among the boilers. However, the explanation below says that is a valid method. Does anyone have any insights? I have set my cogen to track-thermal

EQUIP-CTRL

For a UTILITY meter, accepts the U-name of an EQUIP-CTRL of TYPE = ELECTRICAL that coordinates the operation of multiple generators attached to this meter. In addition, this sequence can operate the generator(s) in a peak shaving mode so that the generators only pick up the load above some upper limit. A LOAD-MANAGEMENT command can select an EQUIP-CTRL sequence that overrides this sequences on the basis of a schedule, outdoor air temperature, etc. This keyword can be used with any of the electric tracking modes (TRACK-ELEC, TRACK-LESSER, TRACK-GREATER); it is ignored for all of the other modes (DONT-RUN, TRACK-THERMAL, MAX-OUTPUT). If not specified, then the program will automatically select the mix of generators that best matches the hourly load. Note that, when tracking thermal loads (TRACK-THERMAL, TRACK-LESSER, TRACK-GREATER), the generator acts as though it were a boiler, and its operation can be coordinated with boilers and/or other generators via the HEAT-EQUIP-CTRL keyword in the CIRCULATION-LOOP command.
