Call service attribute

Hi I need some help.
I have connected to izone in HA but don't know how to call service , its attribute. Below is the entity
and attribute is hvac_modes . I want to call service fan_only, or off. How can I call service?

And set up AC fan_modes: low, medium, high, auto

Can anyone help me? I would be very grateful

Sorry, I can't quite tell. Is this a Node-RED question or a Home-Assistant one?
