Looking for a more modern replacement for my Honeywell

T8602C thermostat controlling Zone 1...
Looking for a more modern replacement for my Honeywell T8602C thermostat controlling Zone 1 through a MABS 2-3 panel. The two features that make the application unique are that the thermostat must have both O and B terminals for changeover control and must be battery powered (there’s no C or Common wire). Any suggestions?

Ya, maybe. Which model do you think might give me battery power, O and B terminals, and remote connectivity?

all of them are battery powered and have a separate O and B terminal. the wifi models do require a C wire. if you still need a wifi thermostat then you can use an add a wire kit if you do not have enough wires for a C wire. other than that there is really no thermostat that will be wifi capable battery powered and have separate O and B.
