Homekit Controller Lenox S30 thermostat Fan Control

I’m trying to understand how / if, I can turn the fan on from Home Assistant.

Current state

I have the S30 added as a device and can see / control the thermostat from HA. In order to get this to work I did have to add it from iPhone using the WAC processs…after that it just appeared in the zeroconf - delightful!

I could not definitively determine if there is a way vis the Climate Lovelace card to turn the fan on.

I have tried calling the climate.set_fan_mode with a variety of values with no result or error messages.

It’s not clear, what the valid values should be - on,off,auto - and/or how to determine if the devices HomeKit integration even support turning the fan on / off
