I have a Traeger Pellet unit that originally used a standard "high,medium,smoke" thermostat.... not digital. I purchased the newer digital thermostat from Traeger, installed it per directions.... now it won't cook at less than 350F.... way too hot for slow cooking and/or smoking..... Any thoughts out there as to how to fix this problem??? I have to assume there was a problem in the wiring directions, but how do I find how and what to change??? Thanks for any help from those of you who are much more experienced than I.....Mercy
