How to change target_temp_high in bang_bang?

Configuration
1

I use

climate:
  - platform: bang_bang
    name: "boiler thermostat"
    id: boiler_thermostat
    sensor: boiler
    default_target_temperature_low: 36 °C
    default_target_temperature_high: 43 °C
    visual:
      min_temperature: 18
      max_temperature: 60

To change target_temp_high try:

actions:
  - choose:
      - conditions:
          - condition: time
            weekday:
              - tue
        sequence:
          - target:
              entity_id: climate.boiler_thermostat
            data:
              target_temp_low: 36
              target_temp_high: 55
            action: climate.set_temperature

Automation works, but
Current {{ states.climate.esphome_web_7590e4_boiler_thermostat.attributes.target_temp_high }}
show 43
