Why do some HVAC systems output 2 streams of heating energy?

I am using a ‘Packaged Single Zone - HP’ system, which is outputting 2 streams of heating energy.

They are:

  • “Heating Electric Energy for COIL HEATING DX SINGLE SPEED 1(kWh)”

  • “Heating Electric Energy for COIL HEATING ELECTRIC 1(kWh)”

Can someone please explain how to interpret these? Can I just add them to get the total heating energy consumption?
