This is an elemental result that is equivalent to the thermal error energy result (PRESOL,TERR) in Mechanical APDL. This thermal error energy result provides a way to gauge the coarseness of your mesh. If a region of the mesh reveals dramatic changes in contour colors from element to element, then that region's mesh is probably inadequate and a mesh refinement should be considered. The numerical values in the legend are not especially significant.

The values for this result have no unit of measure. The description of this result is the same as Error (Structural) except that heat flux is the basis for the errors instead of stresses. However, the structural error result differs in that it has an energy-based unit of measure (Joule, etc.).
