    Hi, I have unlocked my system using the given codes but it’s not letting me increase my heat to warm my home. Also, the unlock is still visible once I complete the inputting the codes, giving me no other options. I’ve taking it off the wall removed the batteries for a few seconds than replaced them backwards for a few seconds. Then removing them and putting them back in correctly. Still no change, please help.
