KETOTEK Digital Temperature Controller AC110V 10A Fahrenheit Thermostat with 2m Waterproof Sensor 2 Relays Heating Cooling Incubator

Have used these in the past 2 years. Replaced many factory ones with these. Very easy to program and no issues at all. Dixell and others have a million functions that you need to set. For a refrigerator this is perfect. I installed one on a freezer with a defrost timer option, let's see how it goes.

I used this in a fruit dehydrator cabinet to keep the air at a constant temperature. One heating element remains on continuously while this controller cycles the other element on and off. So far it works well. I suspect if it is a mechanical relay the internal relay will eventually fail. We will see how long it lasts.

It works great, fully customizable to what temp you want. I installed into a chest freezer and have had no issues.

This is a flimsy product with inadequate instructions. The terminals are fragile and do not hold the wires tight--the wires slip out. A dangerous product in that sense! Not plug and play. You have to wire up what could have come pre-wired. Want to plug your little 200 watt heater into it--well you'll have to butcher the heater's cable--and then it still won't work, and who knows why since the instructions are vague and written in China. Sending it straight back!

I like this thing a lot for the price. I use it to heat my 3D printing enclosure so I can't speak too much on the accuracy but I do like that you can adjust the range for when it clicks on and off. my one big gripe about this thing is that as soon as it's plugged in it by default turns on. What I'm assuming is, is that this may be designed for more long-term temperature controlled applications so that if there was a momentary loss of power when it comes back on it wouldn't stay shut off and ruin whatever you're trying to control the temperature. But for my particular application, which may not be what it was actually designed for, it kind of stinks that I could not be using the printer and be away from home in that if the power went out for a second I would come back to my heater on. However this is easily overcome by hooking up a toggle switch to it we're simply unplugging it when you're not using it. My other gripe and this is the big one is it's a pain in the neck to adjust the temperature. the instructions are written in broken English and it's actually a process of going through a few menus to just change the temperature rather than just pressing up or down on the arrow keys. but it's one of those you get what you pay for and it does work great so I'm not disappointed. If it was more expensive I would probably give it a lower rating but it's a good bang for your buck.

Used this on a little giant 9200 incubator as an upgrade. Works, however you can not set the temp to 99.5.. you can only set it in even 1 degree increments. I watched videos online on how to wire it in and also used the schematic provided to figure it out. Luckily it worked. Otherwise it seems fine

The internal relay no longer turned off after just 3 days of use. The unit was stuck in the ON mode. My guess is the claim to handle a 10amp load is not accurate. My load was 7 amps for the surge and 1 amp thereafter. If u r going to use this device, add a heavy duty relay to handle the load.

I used this for a failed thermostat on a 1953 Frigidaire refrigerator. It is accurate and does the job at an extremely low cost. I only use the 'cool' side of the heat/cool relay set, but after initial setup it has worked flawlessly for a few months. It has also reduced the running cost by keeping a narrower temperature window. It took a few tries to get it set up, but after that I have not touched it. Wiring it into your system is pretty straight forward, I am also running an auxiliary fan to help cool the compressor. I bought one as a spare, and bought another to install on my 1946 GE refrigerator also. So obviously I would buy again.

Tiene buen funcionamiento, no me ha fallado, es presiso, solo la temperatura tiene una diferencia de casi un grado. Si lo recomiendo. Conecte lo como lo recomienda el manual. Yo lo use para una incubadora.

Das Teil macht sehr gut, was es soll. Der Einbau ist sehr einfach. Wäre eine Beschreibung in Deutsch dabei oder eine logische in englisch, dann wären es 5 Sterne.

Great for homebrew
