Nibe Uplink - Detect Passive cooling


I have OH 2.5.0 running with the Nibe Uplink binding connected to a F1145-PC. The connection works great (thanks!)

I’n having trouble though detecting if passive cooling is active or not.

I’ve mapped channel 47412 to a customer channel but that keeps reporting ‘2’ for months…
On the page, X7 is mapped to ‘indication cool mode’.

Does anybody know how to detect the passive cooling state?
