Thermostat Plug Socket

This plug-in thermostat works perfectly! The display is very clear and easy to read. It controls the temperature accurately and keeps my space exactly where I want it. Setup was simple and straightforward. Highly recommend!

I gave this item a 5 star review because it did work for my need to make a freezer work like a refrigerator over the holidays when the original freezer thermostat stopped working. However, it now does something more important for me. We use an electric heater overnight to keep our bedroom comfortable instead of using our HVAC propane heater which would heat half the house also and cost a lot more. Our old heater quit and most of the room heaters these days have electronic temperature controls that are very useful in their ECO mode. Unfortunately, when switching power levels and fan speeds several times during the night they make a lot of relay clicking and fan noise sounds for several seconds, enough to actually wake me up. Not good! So I bought a more old fashioned room heater with a mechanical thermostat, no beeps and no display light to brighten the bedroom. It only had one problem, the mechanical thermostat has about 6F difference between the turn on and turn off temperature (hysteresis) so you are either too warm or too cool multiple times per night. This unit solved my problem completely. This might have worked for the newer high tech heaters but when they lose power they do not automatically turn on with the settings in place before power was lost.

I've took to keeping a space heater in my room lately. The furnace never comes on when it is cold in this room, and when it does, it stays on so very long after it gets uncomfortably hot. So I closed that vent and got a space heater. Problem is. When the "heat" kicks off. The "fan" keeps going. That sucks in two ways. First it way to noisy. Then, the cold air from the fan hurts my head. BUT. turn the thermostat on my heater all the way hot. And use this little gem as the thermostat. And when it turns "off". No more fan. And this is accurate to a tenth of a degree fahrenheit. AND the temperature sensor (thermocouple), is no longer in the heater. Or even the plug. It is on the end of a 3 meter wire. Put that sensor up on the wall and enjoy a "true" 70.4 degrees fahrenheit. You get to set your "turn on" and your "turn off" temperature. So, in my scenario. Kick on at 70.2 and off at 70.4. That is a pretty tight tolerance, yes. And when the snow blows. That heater is on and off, every couple minutes. And when your thermocouple is accurate to a tenth of a degree. A person can do that. This is a must have for my situation. It will also go down. If you put the thermocouple in a refrigerator the the electronics are not functional. Maybe you are going to use it in the garage. It will go into "cooling" mode. If the "start temperature" is higher than the "stop temperature". That setting is automatic. Easy peasy. But as for settings. FIRST THINGS FIRST. You need to pick your measurement scale (fahrenheit or Celsius). You gotta long press "something". The "set" button?? maybe, i don't remember??

Buying appliances in the middle of a supply chain crisis is no fun. When I purchased an extra refrigerator a year ago, I was lucky to find one at all. Unfortunately, I didn't get one that was "garage" certified, which meant I lost a bunch of perishables when my garage got too cold (the ambient thermostat will turn off the fridge when it gets too cold). The solution was the combination of a Diophros 1500W Space Heater, and a KETOTEK Digital Thermostat Outlet Plug. I'm only using the temperature control mode of the KETOTEK, but it's working great. I'm turning on my "dumb" space heater at 10C, and it shuts off at 12C. That's enough to keep the ambient thermostat on my fridge happy, and I won't have to waste a ton of energy on the heater when it's warm enough without it on. The thermocouple seems accurate, and it's great that you can locate it away from the outlet. I don't love that the design of the unit blocks other outlets on my power strip (it blocks 4 of them, due to the specific nature of my power strip). I also don't like that the blue LED is so bright, as it makes the LCD hard to read without direct lighting. Those are minor quibbles, though, as the KETOTEK is an inexpensive and reliable method for keeping my fridge working when the garage is cold - without wasting energy when it's warm enough for the fridge to operate normally.

i wanted my heat lamps to shut off at a fully customizable set point to save on power. this held up all winter with zero issues for the heat lamp it was plugged into

I use this unit to "convert" a vintage (1970's) chest freezer into a refrigerator. The temperature range settings are very easy to adjust, and the included booklet has good instructions to do such. I appreciate that this unit displays the current temperature of the unit (via a temperature probe), as well as the current settings for max/minimum temperature ranges. I have been using this for several months and it hasn't skipped a beat. I have auxiliary analog thermometers in the actual fridge itself, and they indicate the same temperature as the digital readout on the unit itself. It is very user-friendly to set up and adjust. I am quite happy with this thermostat and would likely purchase another one if needed in the future.

Easy to program, easy to use!

Saw them on a technology connections video and knew I needed them. I’d been looking for a good controller for my space heater and these work fantastically. I’ve even got one out in the well house that’s been going strong all winter.

I like that it seems accurate, it's easy to adjust, but I didn't see a manual with it and I don't understand quite yet how the other modes work, but very ideal if I can program a cooling setpoint and heating setpoint! I have this connected to 120v fans mounted on my register upstairs. Upstairs used to be 5-6°C warmer then the main floor, now this helps me keep it within 2°C

I bought it and it worked okay but I need model with powered up cord.
