Custom EMS

SET HeatingSetpoint = <Var,SPTemp,20>,

could be written to indicate that HeatSetpoint can vary and if a Custom EMS variable with Variable key of SPTemp was included in the optimisation, then for each iteration of the simulation, the code in angle brackets would be automatically replaced, behind the scenes, with the setpoint temperature currently being tested, e.g.

SET HeatingSetpoint = 20.7,

The process involved in setting up Custom EMS variables is explained in detail in the Optimisation Tutorial - Custom EMS Variable
