Yes, the Eberspacher 802 is compatible with an Eberspacher D4S Airtronic heater with H Kit symbol. This would be a suitable upgrade if you wish to utilise the integrated temperature sensor. NOTE - the 802 temp sensor requires a connectiuon to the grey cable on the heater controller harness ( the grey cable is not used on the mini-controller so it may be taped back)

Thank you
