## Description

Temperature Controller Humidity Controller & More

Review: Works for my use case. - Five stars because I've not encountered its reportedly shortcomings, as I'm only using a simple temperature on/off function (not timed). Another reviewer studied the unit ad nauseam, and provided revised instructions. I strongly recommend you find that review as a supplement. I can probably use an AI to merge the text, integrate his with the manufacturer's poor guidebook and output a 'new' instruction manual. 😆 I have its temperature probe affixed to the UV lamp on my RO system with thermal tape and Velcro, so that the lamp isn't running 24/7 when the water isn't moving, as that segment gets pretty hot. Some say the UV lamps will last longer if they're not cycled on and off. I suspect it might last longer if it's not getting so bloody hot when there's no water to cool it. In any case, what I spend on replacement lamps I might save in power reduction as an offset. 🤷‍♀️
Review: Great air temp probe - Bought this to regulate the temperature of a towel warmer i made. It has been great. Easy to use, with a very long temperature probe wire. It is accurate in the high low temp setting and easy to change when necessary. Nice thing about the probe is it measure air temp, without having to actually attach to anything, (metal to metal).

## 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.

### ⭐⭐⭐⭐⭐ Works well to convert a chest freezer into a refrigerator.
*by C***Y on December 17, 2024*

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.
