be open before it is permitted to commute from the medium fan speed to 
the maximum fan speed  (object "A/C unit  -  Fan  status" will reflect the 
current fan level; see Table 1).

Step control

:

 

selecting this option ("Yes") brings the 1-bit object "A/C unit - 

Fan  step", which allows increasing (sending the value "1") or decreasing 
(value "0") the fan speed by one level (for example, under the minimum level 
of speed, if the value "1" is sent via this fan step object, the speed will 
become medium). 

 

Precise control

:  selecting this option ("Yes")  brings  the 1-byte object "A/C 

unit - Fan precise", which allows establishing the value, in percentage, of the 
desired fan speed level, according to the values shown in Table 1. 

Step control and Precise control can be jointly enabled, so that the fan speed can be 
controlled in one manner or other at any time, as desired.

TEMPERATURE 

From this window it is possible to configure several parameters related to the setpoint 
temperature sent to the A/C Unit.  

Note that the parameters shown below do not apply in modes “Auto”, “Fan” or “Dry”.
