Fan Only Mode Menu option

[Horse2370]

Is your feature request related to a problem? Please describe:

Fan Only Mode setting
Describe the solution you'd like:

In the Homekit option I have operation modes Off, Cool, Heat and Off.
In the Carrier App I have Cool, Heat, Auto, Fan Only and Off
Describe alternatives you've considered:

I can get Fan Only mode by using homekit to set the Operation mode to Off, then set a fan speed of anything and then set it to off. Note the Fans are always set to Auto.
i.e. with Operation mode set to Cool. Set mode to Off, then go to the fan speed slider, select a few percent, then slide it back to off.
Wall thermostat screen then changes from Mode Off, to Mode Fan Only

Maybe I have missed a setting somewhere???

Additional context:

I am using an Infinity 4 Zone system. I use Fan Only operation most of the time to ventilate the house using Fresh Air profiles to control the ventilation system and turn the furnace fan on low to circulate.
This request is to make setting Fan Only mode easier for others in the house and unify the House controls in Homekit and not numerous different apps.

As a note, your plugin work extremely well on my Infinity Gas furnace, Heat Pump and 4 Zones. Much more responsive than the official application and does 99.9% of what I need day to day. Filter alerts etc. is not something I worry about but once a year and thats on the Carrier System Controller screen. The ability to just expose the Operating mode and temperature is all that is needed for everyone else. Thanks so much for implementing this using the official API.
