Replacing a Hunter 44100 for my mom - its too complicated for her and hard to read.

Its a four wire heatpump setup - Heat/Cool Transformer (R and RH jumpered with 24V in), Fan Relay (G), Compressor Contactor (Y), and Heat Relay or Valve (W)

I have Honeywell 3210D and if someone wouldn't mind confirming I'm getting this right. https://forwardthinking.honeywell.com/related_links/thermostats/pro_3000/install/69_1775.pdf

24V to the (R) terminal
Jumper the Aux and (E)
Compressor contactor to (Y)
Fan relay to (G)
Heat Relay or Valve to (O - Cool Changeover Valve)

I'd hate to make the trip to swap it out, only to find out something like it won't work with a four wire system.

Thanks!
Sam
