+# Loosly based on the Airrounder Plus config
+# Dealing with the overlapping DP modes, decided to retain one climate window
+# and have that auto update rather than seperate Fan and Climate UI's.
+# Mode matrix for reference:
+#  Fan only mode:
+#   Low DP4=heat_low DP5=NatureWind_Low
+#   Med DP4=heat_low DP5=NatureWind_High
+#   High DP4=heat_low DP5=CoolWind_0
+#  Heat:
+#   Low - DP4=heat_high DP5=SleepWind
+#   High - DP4=heat_0 DP5=SleepWind
