AxLink Channels

Each AxLink device contains 255 channels numbered 1-255. The AxLink Channels for the thermostat are defined in the table below.
The Type column indicates who initiates the channel change. The Master directs the thermostat to change its state through
channels with type CMD. The thermostat informs the Master of state changes through channels with type FDBK. Some channels
can be used for both CMD and FDBK.
