swegonventilation ="<data>"

Where

<data> corresponds the data item. See complite list below.

Number	OutdoorTemperature	{ swegonventilation="OutdoorTemperature" }
Number	SupplyAirFanSpeed	{ swegonventilation="SupplyAirFanSpeed" }
Switch	Preheat	                { swegonventilation ="PreheatState" }
