A Great Solution For a Malfunctioning AC Unit

5 out of 5 stars

A Great Solution For a Malfunctioning AC Unit
I purchased this temperature controlled outlet to use with an air conditioning unit that has a compressor relay that is sticking intermittently. The outlet has more functionality than I need, but I really like that it's a "set it and forget it" setup. Once I had my temperatures set and the sensor placed in a good location, I've not had to adjust the outlet at all. I will say that the backlit LED is bright, so I've had to toggle this off after losing power a couple of times. For heat mode, the left temp must be lower than the right and vice-versa to enable cooling mode.

    Device set for heating to start at 45° and end at 50°. However the outlet does not come on at all so my greenhouse got cold. Have read manual and carefully followed poorly written instructions. Should be simple, but it just doesn't work. Junk.

    Reviewed in Canada on November 20, 2024

    I bought this to control a 1500 watt heater in a small outdoor insulated shed, to keep it between 6.5 and 9.5 Celsius (that's 44 to 99 F).
    It worked flawlessly for a month now and seems pretty accurate at those temperatures, measured against two old school red alcohol thermometers.
    It's also very easy and intuitive to program, either to start a heater or an
    air conditioner

    Works really well and saves on energy!

    Reviewed in Canada on September 25, 2025

    I purchased this thermostat for my sunroom to operate my heaters. I place my seedlings in the sunroom in early spring and I have the thermostat set to come on when the temperature drops below 12 C and shut off at 15 C. I no longer have to worry if my plants will freeze overnight and I am not wasting energy by running the heaters when it warms up. I would definitely buy again.
