97 Switch speed 2 Fan DPT 1.001 1 bit CW
98 Switch speed 3 Fan DPT 1.001 1 bit CW
This object is used to receive a control value for fan speed. An OFF telegram to one of the three
communication objects, fan speed 1-3, switch off the fan completely. If the object received,
automatic mode is set OFF.
0 : fan OFF
1 : fan ON
99 Fan speed UP/DOWN Fan DPT 1.007 1 bit CW
This object is used to switched one fan speed further up or down via 1-bit telegram.
0 : fan speed DOWN
1 : fan speed UP
100 Status fan ON/OFF Fan DPT 1.001 1 bit CT
The status of fan coil channel is visible via this communication object.
0 : complete fan coil channel inactive (all outputs OFF)
1 : any output of fan coil channel is switched ON
