Carrier My Infinity Integration into HA


I am a newbie to HA and not a programmer. So far have been successful in installing HA, Shelly devices, Node Red and basic automations.

I would like to add my Carrier My Infinity HVAC to HA but cannot understand how to do it. Others have developed a custom component for this -

I cannot figure out how to get from the custom component to controlling various HVAC controls in HA.

Any help will be appreciated.

Thank you
