Nest Thermostat and Aprilaire 760

Hello - I am installing a new nest thermostat. Below is an image of my current configuration:

As you can see, in my current configuration I have a Bryant Plus 90 Furnace which also has central air conditioning and an Aprilaire 760 humidifier. I am hoping I can find someone who can validate the proper installation of a next thermostat. The next image is a diagram of what I think I need to do to properly install my nest thermostat using the Aprilaire 760 humidifier:

I am hoping that someone knowledgeable could take a look at my proposed configuration and let me know if I have it correct, especially the use of the 6AZU2 relay.

Thanks - Steve

Welcome to the forums.

The humidifier doesn't require switched AC power. It can be plugged into an always live receptacle.
