Best Compatible Thermostat for My System?

My Totaline thermostat broke yesterday, and I need to replace it.

Can someone recommend the best thermostat to replace it with? I am not sure what is compatible with my system.

I have a white wire attached to AUX/E in my current setup. I don't know if I have emergency heat or what that wire does.

Any help would be greatly appreciated.

Broken Thermostat: Totaline P310-0210
Outdoor Heat Pump: Payne PH15NA036-A
Indoor Unit: Payne PF4MNA037
City/State: St. Pete, FL

A picture of the wiring is attached.

Best or just compatible?

Professional thermostats :
HIGH END = Honeywell Prestige
MIDDLE OF THE ROAD = Honeywell VP 8000
LOW END = TH6220

CONSUMER thermostats :
HIGH END = RTH9580WF
MIDDLE OF THE ROAD = RTH8580WF
LOW END = RTH7600D

There are of course others that are compatible... I recommend you spend at least $75 for a quality thermostat.

Thank you so much hvactechfw. I got the RTH7600D.

Do I put the white wire that currently goes to the combined Aux/E terminal to the Aux or E terminal in the new Honeywell? The manual mentions placing a wire between them if E and Aux do not each have a wire connected. Do I need to do this with my setup?

Thanks
