Honeywell Prestige IAQ and Aprilaire 700

[Jjfuhreck]

Bought both an Aprilaire 700 and an HVAC buddy recommend the Honeywell Prestige IAQ to control it. Buddy was supposed to help install both but he has ghosted me. Can anyone offer any instructions on how the low voltage wiring should be done??

Need all the numbers off stat, iaq module, brand and model #off furnace or air handler. That stat doesn't show RH or a terminal.

Picture in original post is my existing thermostat. I posted it to show how it is currently wired and that I have one unused wire. Buddy said the new setup will require 5 total wires.

Can't find a wiring diagram on the furnace. Stat needs to be programmed for humidifier and dry contacts U1 to energize humidifier
