Review: Termostato - 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!
Review: Unexpected Use for Controlling a Room Heater Overnight When it's Very Cold Outside - 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.

## Questions & Answers

**Q: Can I dip the temperature sensor in water?**
A: I used mine with the sensor immersed for about a year. This was in a water bath in a crockpot for inexpensive sous vide cooking. I also used it for making yogurt. It failed after about a year and in my reading on the issue, this sort of failure  is common if the sensors are immersed for long periods. I recently  got a replacement unit and I will be protecting the sensor by using it with a thermowell, which is a close-fitting metal tube that is immersed in the liquid and sealed at one end, but open to the air at the  other.

**Q: Is this device UL certified?**
A: Hello, this device is not UL certified.

**Q: How long is the probe cord?**
A: I believe the picture shows it is 118 inches.

**Q: Specs say the most power it handles is 2a inductive, nowhere near enough for a freezer or basically any ac. have many of us used it for that anyway?**
A: I don't know what inductive load is. I use it on an infrared lighting fixture in a greenhouse that pulls about 15 amps without problem. The specs also list it as ok for refrigerators and freezers.

### ⭐⭐⭐⭐⭐ Just excellent
*by M***L on January 4, 2023*

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??
