3. 8. 2 LED Ring
These registers can be used to determine or override the default color and behavior of the
LED ring.
Ring brightness in normal operation and ring brightness in SLEEP mode can be individu-
ally set. The ring colour and style normally change automatically based on hvac mode
(heating = orange, cooling = blue…) received from controller (Refer
HVAC mode selection).
The master controller can override the automatically determined colour by writing a value
to the ‘Ring Colour’ register. The format is RGB565 (5 bits red, 6 bits green, 5 bits blue from
most significant to least). A value of 0 (corresponding to black) represents AUTO mode,
meaning the LED ring changes colour according to currently active hvac mode.
The controller can also override the ring style by writing to holding register 1101.
3. 8. 3 Temperature display configuration
It is possible to disable temperature unit change on the wall module and have it fixed in
Celsius or Fahrenheit.
