     |      You can confirm that it works by calling self.is_heating_enabled
     |  
     |  set_heating_schedule(self, schedule: dict[str, dict[str, float]])
     |      Sets the heating schedule for the heating.
     |  
     |  set_holiday_mode(self, on_holiday: bool)
     |      Whether to turn the holiday mode on(True) or off(False).
     |      You can confirm that it works by calling self.is_holiday_mode
     |  
     |  set_setpoint_temperature(self, setpoint_temperature_c: float)
     |      Sets the heating setpoint (target) temperature, in °C
     |  
     |  set_tank_heating_enabled(self, powerful_active: bool)
     |      Whether to turn the water tank heating on(True) or off(False).
     |      You can confirm that it works by calling self.is_tank_heating_enabled
     |  
     |  set_unit_datetime(self, d)
     |      Sets the datetime of your unit. Does not work on all units
