This probably means that you did not list the heat pump in the AirloopHVAC branch list. Follow the "Branch List Name" in the AirloopHVAC object to find what is defined for that air loop.

I want to model 2 UnitaryHeatPump:AirToAir in one zone.
I set ZoneHVAC:EquipmentList, ZoneEquipment1 for first UnitaryHeatPump, ZoneEquipment2 for second UnitaryHeatPump.
But I had a severe error
" ** Severe ** AirLoopHVAC:UnitaryHeatPump:AirToAir = 1-HEAT_PUMP
** Severe ** Did not find correct AirLoopHVAC."
I model a UnitaryHeatPump:AirToAir and a FanCoil in one zone. But I had no Error.
