cannot heat DHW

[michalholes]

Hello,

I dont know if its my fault or not. But I cannot enable heating of domestic water in Home assistant. Part of my configuration.yaml:

 - name: "DHW"
    unique_id: "DHW"
    modes:
    - "off"
    - "heat"
    current_temperature_topic: "opentherm-thermostat/dhw-actual-temperature/get"
    mode_command_topic: "opentherm-thermostat/dhw-state/set"
    mode_state_topic: "opentherm-thermostat/dhw-state/get"
    temperature_command_topic: "opentherm-thermostat/dhw-temperature/set"
    temperature_state_topic: "opentherm-thermostat/dhw-temperature/get"
    min_temp: 12
    max_temp: 60
    value_template: "{{ value }}"
    temp_step: 1

And here is my screenshot from HA:

Please, can you write me, if I made a fault in config?

Thanks a lot.
