Expose climate entity fan_mode via modbus integration

Feature Requests
1

The modbus integration’s climate platform works really well for my air conditioning. It exposes most of the functionality through the register parameters like hvac_mode_register. The fan mode of the Climate entity doesn’t have an associated parameter on the modbus integration. Is it possible to add this?

I’m new to this, i have started to build code recently, could you please sharing me the config.yaml for reference? Thank you so much

I’d really like to see fan mode and fan speed controls added to modbus climate entity as well. Hopefully more people will vote for this feature request. Here is an example from my Australian Actron system for reference. Full manual and modbus registers can be found here.

Same here, hope it will be implemented
