Example dual-point configuration entry

should include this to work:

heat_cool_mode: true

so something like this:

# Example dual-point configuration entry
climate:
  - platform: thermostat
    name: "Thermostat Climate Controller"
    sensor: my_temperature_sensor
    min_cooling_off_time: 300s
    min_cooling_run_time: 300s
    min_heating_off_time: 300s
    min_heating_run_time: 300s
    min_idle_time: 30s
    heat_cool_mode: true
    cool_action:
      - switch.turn_on: air_cond
    heat_action:
      - switch.turn_on: heater
    idle_action:
      - switch.turn_off: air_cond
      - switch.turn_off: heater
    default_preset: Home
    preset:
      - name: Home
        default_target_temperature_low: 20 °C
