Which Lennox controls to use w/XP19 HP?

[battleground_bluto]

Is there any benefit with using the Lennox Signiture Controls with the XP19 Heat pump system outside of humidity control? The contractor spec'd out the Elite series controls and I want to know if I'd miss out on anything (like efficiency) by using the Elite series controls with the 2-speed heat pump & vari speed airhandler verses the Signiture series controls. Humidity is not a big issue here (SW Washington State).

Thanks,

as long as you don't need the humidity control the elite stat is an excellant choice. same as honeywell vision pro. make sure they use the multi stage stat.
