Set and forget. A good thing!

Works well - the temperature probe is long enough to place in a shady spot for precise control. Stores settings without battery - can be switched between solar panel and fan motor. Two months later it works like new.

Pros
  • Quality construction
Cons
  • Empty

Works well at a great price

Just installed, very easy if you follow the instructions in the description (they are not included in the package). Actually works much better than expected. Using a computer fan to ventilate an enclosed cargo trailer from a solar panel/battery. Plan to upgrade in the future if you run into issues.

Pros
  • Excellent construction
Cons
  • Reliability

very favorable temp. Controller

I use this to control my fridge's exhaust fans. Nice instruction, except that the output on the yellow wire passes through the supply voltage when the output is on. That would be good info. in the instructions. It would also be nice to have a tempo. in hail F, but not necessarily.

Pros
  • Great Price
Cons
  • Easy Serviceability

Very useful in hydroponic greenhouse

Needed to control greenhouse fan operation. This mini thermostat has turned out to be quite suitable. In combination with a relay, a timer and a fan speed controller, this mini thermostat works very well. The main meat are short braids; double length recommended. This beef and the temperature readings in Celsius. I could switch to metric if I had 10 years to adapt, but converting Celsius to Fahrenheit is a math problem. Coding becomes child's play with YouToob videos and following an unwritten…

Pros
  • Made of 1.8mm thick ABS material, high security, anti-aging, strong and durable.
Cons
  • Very expensive

Confusing structure but great little controller

As others have written this is a cheap but good little unit. There is no manual but I found this YouTube video very clear on wiring and programming. Just watch XH-W3002 Thermostat Wiring and Programming on YouTube and this guy from Australia will walk you through everything step by step. Note: The 220V version is used but the programming is the same. If you're using this for cooling, just set P1 to the temperature you want to turn on and P0 to the temperature you want off. Example: Mine is set…

Pros
  • Three buttons for easy operation, set start temperature, end temperature, set temperature, start delay.
Cons
  • Expensive
