Hi, I've recently been using the heater pro (us plug) for my 30cm cube and have set the wattage limit to around 40-50w but have noticed a constant overheat/very fast heating after waterchanges. Ive confirmed that the issue is that no matter what wattage I set the limit to, it will use around 570 watts no matter what. When plugged into my ups, the fault light triggers whenever it is in heating mode because it is using too much power. On both the app and unit itself, the set wattage limit is displayed correctly but current watt useage on the app is around 570 whenever it powers on. Ive attached an image on the app that shows even with an 8 watt limit, it will still heat with 571 watts and trigger my ups fault alarm.
