It definitely has an a/c function (it will cool an enclosed space using refrigerant 410A) so if it is not a heat pump, then it is an a/c.
Technically an a/c is a heat pump in that it acts to pump heat out of an enclosed space, but in common parlance a "heat pump" is an a/c unit which can be switched to pump heat into an enclosed space using the refrigerant.
According to the label it has a "heat package" (EHK10AKN3 P/N 327929-406) which is not further specified. This heat package could be connections and devices using the refrigerant to heat the interior space in which case it would be a heat pump (pumps heat into the space), but this package may be simply electric resistance heat elements (large coils which get hot and are in the air stream). I suspect the latter, but can't say right now.
I am surprised that the labeling on the unit does not state that amount (kg) of refrigerant 410A the unit contains and that it does not give the rating in BTU/h. Are there other labels on this equipment?
Look at the information labels on the outside unit. That will probably give you insight into whether this is a heat pump or just an a/c.
