Dear GHL Support,

My new Profilux 3ex system (Firmware 6.14) is displaying an incorrect temperature of 30.0 C. Measurements with a Salter Digital thermometer and JBL Mercury thermometer adjacent to the GHL sensor record 27.6 and ~ 28 C.

I've examined a few forum threads on this topic and have attempted to follow the process of adjusting the temperature via GHL Control Center 1.0.6.6 lowering by 2.4 C. After completing the "Adjust Temperature" I find the "Save changes" icon is greyed out.

Confirming if the change has been applied by placing the temperature sensor in a cooler container of water yields no change in the displayed value.... so clearly no settings have been updated.

Choosing to Calibrate the temperature sensor prompts for the ADC1 and ADC2 values (not knowing what these offsets could be) I choose OK and presto the "Save changes" icon is available, selecting this resets the temperature to 30.0 C.

Not the desired result I'm looking for.

Could you please suggest how I can resolve this issue taking note that I'm new to this product.

Many thanks
