Coil:Heating:DX:MultiSpeed - rated waste heat fraction of power input

Hi,

I'm trying to setup an idf file with a Coil:Heating:DX:Multispeed object. I've read the engineering manual and the input-output manual and I still can't figure this out.

What is the waste heat fraction? I set this to 0.0 and I get an error:

* Severe * <root>[Coil:Heating:DX:MultiSpeed][Heat Pump DX Heating Coil][speed_1_rated_waste_heat_fraction_of_power_input] - "0.000000" - Expected number greater than 0.000000

I don't know why I need to have a waste heat component in the heating component of a heat pump.

Could someone help me understand what this value does?

Thanks
