I bought a Tpriv and love it so I also bought a Valyrian tank and the coil is 0.15 ohm 95-120 watts so I adjusted it to the spec cus it barley hit now it blinks red and looked up other specs and still same thing now it did work very well for a week and all of a sudden blinking red . Can anyone give me advice on how to fix the issue ? I would be grateful.
