Chiller EIR default rated condition and curves don't match

The Default Chiller:ElectricEIR creates has a problem... At the rated conditions, the CAPFT and EIRFT will return a value different than 1.

model = OpenStudio::Model::Model.new
chiller = OpenStudio::Model::ChillerElectricEIR.new(model)
ref_lchwt = chiller.referenceLeavingChilledWaterTemperature
ref_ecnwt = chiller.referenceEnteringCondenserFluidTemperature
eirft = chiller.electricInputToCoolingOutputRatioFunctionOfTemperature

# EIRFT is wrong
eirft.evaluate(ref_lchwt, ref_ecnwt)
# => 0.8614399290202399

# CAPFT is wrong
capft = chiller.coolingCapacityFunctionOfTemperature
capft.evaluate(ref_lchwt, ref_ecnwt)
# => 1.0554712015060401

# EIRFPLR is ok
eirfplr = chiller.electricInputToCoolingOutputRatioFunctionOfPLR
eirfplr.evaluate(1)
# => 1.00138225
