Elite Direto as indoor trainer in Garmin wrong speed

[eder.alvarez]

Hi,
I have purchased an Elite Direto Smart Trainer.
When i connect it to Edge 820 as Indoor Trainer Sensor, and the wheel circumference set to 175mm as Elite says, the speed is only of 2-3 km/h, very low. If i set for example wheel circunference to 17mm the speed increases x10.

If I disable Indoor Trainer Sensor and enable Cad/Speed sensor of the same Elite Direto trainer with 175 wheel circumference, the speed is correct.

What is the correct wheel circumference configuration for good speed readings using Elite as Indoor trainer sensor?

​​​​​​​Best Regards,
