Hi there,

If I specify a series of data points in the part load curve dialog for a heating or cooling system, can anyone advise how the calculation handles a part load % that is in between two data points? For example, if I have 70 and 80% load but 73% is specified, would IES interpolate between these two data points or is there a step function that is applied, i.e., we would be at 70% load until 80% is reached?

Thanks!
Mark Hallman.

Mark,
Apache would interpolate between the 2 data points.

Thanks so much!
