A thermostat is basically an on-off switch, that is controlled by temperature. They have inexpensive analog type dial thermostats(No digital readout) that may work just fine to turn ONLY your AC on and off.
With the heat pump, then you will need a thermostat that can handle both the heat and cooling functions and switch the proper valves to reverse the operation.
The only thing you need to do is look at the wiring diagram and figure out which wires turn the AC on and off and hook them up to your new thermostat. Taping off the other wires to be used at a later date when you install the full function thermostat.
