I have a Carrier Heat Pump that I am going to be replacing soon with a Magic Pak 7MHP10A24 heat pump, and would like the contractor to install a good programmable thermostat as well. He recommended a Honeywell, but hasnt come back with a model number. While reading this forum, I saw a lot of recommendations for the Honeywell Vision Pro 8321 as well as the White-Rodgers 1F95-391:
The Honeywell is a good thermostat, 5 year warranty, lots of features, excellent user interface, very well marketed and very expensive(?).
The White-Rodgers is a good thermostat, 1 year warranty, even more features, classical user interface , not as well marketed, not as expensive(?).
I believe in the 80-20 rule, so I am trying to find out what features are actually very useful for our situation, and not buying something just because it is best. So I need help figuring out these features and their usefulness:
Internal and External Remote Sensors:
How easy is it to install these sensors?
Is there a maximum length of the sensor wire?
The indoor sensors help averaging out the temp, does the external sensors change the algorithm also?
I would also need to figure out how to conceal the wiring, so are there compatible wireless sensors?
Humidify and Dehumidify control:
Will this work with the new Magic Pak heat pump?
Again, will this work with the new Magic Pak heat pump? and wouldnt the Heat Pump fan need to be a variable speed fan for this? [I cant figure out from the spec sheet]
Do thermostats go bad? The Honeywell Vision Pro 8000 series seem to have a 5 yr warranty, while the White-Rodgers seem to have a only a 1 year warranty.

The old thermostat is a Carrier branded Honeywell thermostat with this on the board:
