Applications that have more complicated requirements (for example having two different cool-
ing systems within the same room) can use the advanced mode.

Register 1201 allows a master controller to control the LED ring to indicate the status of cool-
ing and heating in the room. A constant blue means that cooling mode is active, but is not cur-
rently switched on. A constant orange means that the heating mode is active, but is not
currently switched on. The ring begins to breathe as soon as the room is cooled or heated. A
breathing green means the fan is on with no cooling and no heating. Gray means that no cool-
ing and no heating is currently possible; the central cooling and heating system is turned off or
the room user has disabled cooling or heating via a HVAC Mode overwrite. Register 1201 is
encoded as follows:
Bit representation: 000D CCBB 0000 0AAA
• AAA (bits 2-0): currently active hvac mode
• BB (bits 9-8): Heating outputs status
• CC (bits 11-10): Cooling outputs status
• D (bit 12): fan output status
• Bits 2..0:
• - 0: heat & cool not available (grey ring)
