Review: Specification issues between what you can see on desertcart vs. what's in the user guide. - I gave this item a 5 star review because it did work for my need but the specs you can see on desertcart don't match those in the user guide that comes with the unit. Looking at the item on desertcart it appears that the unit will control appliances up to 120VAC/15A. I needed it to control the temperature in an old freezer over Christmas that still works but the thermostat is dead. So, I bypassed the freezer thermostat and intended to use this device to turn the freezer power on at 40F and off at 34F so it would basically be a refrigerator. Reading the user guide while setting it up I saw the the unit is mainly designed to control a resistive load 2A/240W. Anything with an AC motor is an inductive load (fans, refrigerators, freezers, etc.). My freezer would technically exceed the 2A inductive load but I was out of time and had to use it anyway. It worked perfectly for over two weeds and is still working fine though not in use as the moment. Oddly, the user guide says the unit is "widely used in heating, refrigeration..." so that is confusing since refrigeration usage appears to violate the 2A inductive load spec. As an electronics engineer I have many years of experience with AC and DC relays. In most cases, relays do better switching AC loads with some inductance than DC loads since any inductance in a circuit causes an arc when disconnecting the load and when switching AC loads the arc is extinguished when the voltage polarity changes within a few milliseconds. That doesn't happen with a DC load so the contacts on relays designed for switching DC loads are typically much beefier to handle the arcs. Other than the spec confusion, this is a great little unit!
Review: This has worked great for our heater application - Working great so far. using it to control a Ceramic heater for my well pit. It have multiple settings and ways to control what you need for your application as well, not just on or off.

## 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.

### ⭐⭐⭐⭐⭐ Specification issues between what you can see on Amazon vs. what's in the user guide.
*by J***K on January 8, 2026*

Reading the user guide while setting it up I saw the the unit is mainly designed to control a resistive load <14A, like a heater element, and should not be used for controlling inductive loads >2A/240W. Anything with an AC motor is an inductive load (fans, refrigerators, freezers, etc.). My freezer would technically exceed the 2A inductive load but I was out of time and had to use it anyway.

### ⭐⭐⭐⭐⭐ Great air temp probe
*by T***S on November 11, 2025*

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).
