Thanks for taking the time to clarify. This makes sense.

It's basically Q = Mdot * deltaH from fan coil inlet to outlet. Since the inlet is the zone exhaust node, then it's the impact of the energy transfer from the supply air leaving the fan coil with respect to the zone conditions. As long as the fan is on, this report will be non-zero (and never 0 or very rarely coincidentally 0)
