What it controls
The Emerson 1F97-1277 Programmable Thermostat is a programmable. Its listing doesn't spell out which heating and cooling systems it supports, so run the maker's compatibility checker before you buy.
Check your wall for a C terminal: the listing doesn't say whether it needs a C wire. The C wire guide covers adapters.
The maker states heat pump support ("7-1277 Touchscreen 7-Day Programmable Thermostat for Single-Stage and Heat Pump Systems by"), so it can drive an O/B reversing valve. What a heat pump needs from a thermostat.
Stages, per the maker: Single-Stage. A second-stage wire (W2 or Y2) at your old thermostat needs matching support here. Single- and two-stage systems.
Schedule: 7-Day Programmable. Program sleep and away setbacks once and it runs them every week.
