This specific controller, unlike the rest of the Westinghouse ones, gives the option of selecting the desired temperature. The greater the temperature difference in the room (always upwards) compared to the one selected, the fan operates at higher speeds. As the difference decreases, the speeds decrease, and if the room temperature falls below the desired one, it shuts off. Therefore, it solves the problem of starting with full heat at night and having to manually turn it off in the morning if it gets cold. Additionally, it also has a timer, but perhaps the other ones have timers as well.
