I have two zones, with two speed handlers. The original wire was only 4 wires so I had the AC guys drop new 7 wire when they installed the new units. (Two stage on heat and cool, one wire not used.) If you have only 4 wire it is real simple to hook up.
It looks confusing, but it really isn't when you read through the instructions one by one. Oh, and print that .pdf because the manual that comes with it is almost unreadable.
They work GREAT!

She just got a new 13 SEER Goodman heat pump to replace her older Janitrol unit, however, the existing air handler was retained. The last time I was there, she simply had an analog Trane thermostat. Not sure how old the air handler is, however, I don't believe she has a two-speed air handler.
Assuming she has the 5 wire setup for heat pumps with aux heat, should the R wire connect to the RH or the RC terminal? The text instructions say to connect it to the RH terminal but the diagram says to connect it to the RC terminal.
