Daikin and Virtual Mode

hi all, I’m looking for a correct configuration of my daykin (BRP069B41 module) with alexa.
I made this:

Group      gClima_Sala                         "Clima Sala"                                                           {alexa="Endpoint.Thermostat"}
Switch     Power_Clima_Sala                     "Power"            <switch>             (gClima_Sala)                   {channel="daikin:ac_unit:192_168_1_84:power", alexa="PowerController.powerState"}
Number   SetPoint_Clima_Sala                 "Setpoint [%.0f °C]"  <temperature>        (gClima_Sala)                   {channel="daikin:ac_unit:192_168_1_84:settemp", alexa="ThermostatController.targetSetpoint"}
Number   IndoorTemp_Clima_Sala          "Temperatura Interna  [%.1f °C]" <temperature>   (gClima_Sala, gChart)      {channel="daikin:ac_unit:192_168_1_84:indoortemp", alexa="TemperatureSensor.temperature"}
Number   OutdoorTemp_Clima_Sala       "Temperatura Esterna  [%.1f °C]"  <temperature>   (gClima_Sala, gChart)     {channel="daikin:ac_unit:192_168_1_84:outdoortemp"}
String       Mode_Clima_Sala                      "Mode "             <climate>             (gClima_Sala)                  {channel="daikin:ac_unit:192_168_1_84:mode", alexa="ThermostatController.thermostatMode" [binding="daikin"]}
String       FanSpeed_Clima_Sala              "Fan"                   <fan>                   (gClima_Sala)                  {channel="daikin:ac_unit:192_168_1_84:fanspeed", alexa="ModeController.mode" [supportedModes="AUTO=@Setting.Auto,SILENCE=@Setting.Quiet,LEVEL_1=Level One:@Value.Low,LEVEL_2=Level Two,LEVEL_3=Level Three:@Value.Medium,LEVEL_4=Level Four,LEVEL_5=Level Five:@Value.High",friendlyNames="@Setting.FanSpeed,@DeviceName.Fan",ordered=true]}

Now, I can power ON/OFF, move up and down the temperature but nothing else like SET the temperature, switch the mode or set the fan speed. I read about a Virtual Mode on 2.5-4 version but I cannot find documentation. Could someone help me please?
