need 5 wire thermostat with heat anticipator

Just bought condo and need to replace thermostat with one that has a 5 wire connection and heat anticipator to adjust for shorter more frequent cycles. The newer ones can handle 5 or more wires but no adjustable cycles, the older type have adjustable cycles but only have 4 wire connections, HELP

    Is that all you need?
    Is it a heatpump? Is either terminal O or B being used?
    Theres only about a bajillion thermostats that offer those terminals.
    Look at the Honeywell T6 Pro. Nice but simple. You set the CPH as needed.

    What are the 5 wires used?

    Your making this harder than it has to be. A common wire is not needed but optional with Honeywell T4. It uses batteries to operate.
    Is this a conventional gas/electric setup or heat pump?
