Regolatore di temperatura digitale doppia sonda 10A 1200W per ventilatore tappetino termico terrario

Probably it is the Alarm settings ( AL、AH、d7 ) you set areNOT the right temperature you want. AL is low temperature alarm(it sounds when current temp is AL or Lower), AH is high temperature alarm(it sounds when current temp is AH or Higher), d7 is difference alarm(it sounds when the temp deviation between sensor 1 and sensor 2 is over d7).
