Honeywell Visionpro TH8320
Honeywell Visionpro TH8321 w/ humidity display

Honeywell RTH8500D , it has less options than the Visionpro series but it's available at your hardware store.

I use the Visionpro TH8321 and I really like it.

The Visionpro TH8110 will not support your system.

It appears that your new stat will not support your multistage heatpump. The T7350B will.

If you get a multistage heatpump stat:
Black = E
Blue = C
White = Aux
Orange = O (or O/B)(O/B would have to be configured for O)
Red = Rc & R
Green = G
Yellow = Y

Configuration:
Limited configuration can be done with the keypad using
the Configuration ID. In order to determine the proper
codes to use for the Configuration Variables (CnfgID).
NOTE: Spreadsheets of the CnfgID values are available
online at http://customer.honeywell.com
The PDA T7350 Configuration Tool or the PC Tool
LonSpec can also be used as follows:
1. Open the PDA Config Tool Application.
2. Select the desired configuration.
3. On the summary screen, tap CnfgID.
4. The PDA determines the proper CnfgID.
5. Make note of the values.
6. Press both Copy and Run Schedule.
7. Tap until C1 appears on the right end of the display.
NOTE: While stepping toward C1, check other
items to ensure they are set properly. See
Setup Using Keypad section.
8. To adjust each variable to match PDA indication:
a. Hold down the up �� or down �� key to adjust
the value quickly.
b. Tap the up or down key for fine control.
9. Tap to switch to another variable.
10. Return to step 8 and repeat the process until all
configuration values are set properly.
11. To exit the Installer Setup, press Run Schedule.
