I am trying to set this option to the OS:Site:WaterMainsTemperature using the following syntax:

w=model.getSiteWaterMainsTemperature
w.setCalculationMethod("CorrelationFromWeatherFile")

but it always returns false. Am I missing anything? Is this option implemented in OpenStudio.

It appears that EnergyPlus added this calculation method in v9.0 but it has not yet been made available in OpenStudio. I have filed an OpenStudio feature request.

In the meantime, your options are:

Set the calculation method to "Correlation", in which you will have to process the weather file yourself and set the appropriate values (average outdoor drybulb, monthly differentials), or
Use an EnergyPlus measure to set the calculation method to "CorrelationFromWeatherFile".
