Control A/C Fan

Hi ?
I love HomeWave ? great app!
I?ve got HomeWave connected to my CT100. It controls the AC perfectly.
I can?t seem to find how to turn just the fan on/off.
With Vera Mobile there is a ON/OFF button for the fan, but I can?t find the control for Home Wave.
Any ideas?

I have the Trane thermostat, and can do this.

Create a “Thermostat Settings” control in HomeWave
Link it to the thermostat
Select the new device, and hit the setup icon (wrench)
Change “Controlling: Mode” to “Controlling: Fan”
Change it to “Rose” if you want instead of “Buttons”
Hit OK
Hit Save

That worked great, thanks.
