Look in the mtd file and find the meters in question. That file will show you what is on each meter. The Heating:EnergyTransfer meter is, if I recall correctly, a sensible only meter. The HeatingCoils:EnergyTransfer is likely total energy transfer, including latent. This would explain why the heating coil energy transfer is larger than heating energy transfer. In fact I just went through this for AHSRAE Std 140 where the html District Heating energy was larger than the Heating:EnergyTransfer and I was confused, until I realized the difference between a meter including latent heat and one that does not.

In the fan model the Electric Power Minimum Flow Rate Fraction = 0.2. At flow fractions below 0.2 the fan power will remain constant. At 0 flow the power will go to 0.
