I have a Quadra Fire gas stove with a smart-stat-II remote that will not work. The remote says E 5 and will not function at all. I have tried to reprogram the remote using the learn function and still nothing. Does anyone know what the E 5 on the remote means? Also would I be able to replace this remote system with a different brand? I am assuming they are all pretty much universal. Any help would be appreciated. Thanks!
