I don't know if it's only me but I just started using the temperature control on the rdna40 now that I got some coils to use it with. I have used it for like 5 or 6months now in v/w mode with regular coils. But since I started using the temp control it seems to fire weirdly and draining my battery way way faster than normally. I know obviously there is going to be a difference in how it works but I don't think it is working right. Am I supposed to adjust the wattage also or just set the temperature I want it at and let it do the work? I have tried changing the wattage to see if it made a difference but it doesn't, at least nothing noticeable. Anyone having this problem or know what I'm doing wrong maybe.
