No "HEATING" attribute when Turn On H7130 by toggle

[HarryGYao]

There is an error when I toggle to turn on my heater, it looks the following code cause the issue.

    async def async_turn_on(self) -> None:
        """Turn the entity on."""
        await self.async_set_hvac_mode(HVACMode.HEATING)

The following change will fix my issue.

    async def async_turn_on(self) -> None:
        """Turn the entity on."""
        await self.async_set_hvac_mode(HVACMode.HEAT_COOL)

Could you help review if the HVAC mode for turning on depends on the device?

Thanks
