The Good The Emerson 1F78-151 thermostat reliably automates your weekday and weekend temperature presets.

The Bad It feels cheap, has a particularly bland design and doesn't come with a backlight for making manual adjustments in low-light conditions.

The Bottom Line Emerson's 1F78-151 programmable thermostat is fine, but its competitors offer more in terms of features and design.

Of the five affordable programmable thermostats I've reviewed to date, Emerson's $43 1F78-151 -- sold on Amazon for $26 -- is the least interesting. Sure, it will dutifully adjust the temperature for you four times a day, but it really doesn't have much else going for it, and that makes it hard to recommend for purchase over most of its competitors.

To begin, the 1F78-151 doesn't come with a backlight like the Lux TX500U, the Hunter 44157, the White-Rodgers P200 and the Honeywell RTHL2310B. Of course, not having a "nightlight" feature isn't exactly a deal-breaker at this price range, but it would definitely make the small display easier to read -- especially in low-light situations.

This thermostat also feels cheaply made from its white plastic casing to its buttons and its display. I know, all of these thermostats cost at or under $30, so what should I expect? But some of these competitors really do stand out by comparison, especially the streamlined, backlit Lux TX500U.

To appear more minimal, many manufacturers attach a plastic covering to their thermostats. That way, you can flip open the covering when you need to access certain buttons and can otherwise keep them covered. Instead, Emerson's 1F78-151 displays everything up front in a way that looks cluttered.

Its default is also to flash the time and the current ambient temperature reading, something I find slightly annoying. I would much rather the thermostat display stay fixed and not alternate between different types of information. The Emerson 1F78-151 is decent, but I would consider the Lux TX500U or the Honeywell RTHL2310B instead.
