Temperature will not go above 200 degrees C

Just Purchased my Fixhub portable power station, when attempting the first use, I turned the knob to adjust the temperature, It was able to decrease the set temp down to 200 degrees, but when turning the knob to the right it does nothing, just stays at 200. It came with installed firmware version 1.3.0, and I did try to downgrade a version just to test with no luck. When pressing the knob to change the temperature units, the cursor would not move down to Fahrenheit. If I am missing the correct way to adjust temperature or if there could be something defective about my unit i would appreciate answers.
