Review: Works great if you follow the instructions - Read through reviews and there are so many reviews about it simply not working straight out of the box. Unfortunately, based on what a lot of the reviews say, that's probably more to do with user error than the unit itself. The wiring isn't exactly intuitive and if you don't read the instructions you're going to have a bad time with a seemingly broken unit. You can even see the wiring diagram in the product listing pictures. Before giving up on the unit make sure you wire it properly according to the instructions Only time will tell how long this lasts but right now it's a great little temperature controller.
Review: Works great for low-amp loads - I bought this controller for a portable fish tank that I'm building. It works great for controlling the cooling pump. Easy to "set and forget" - just what I needed and at a very reasonable price. Two thoughts, though, based on some of the negative reviews I've seen: 1) The relay in this controller is rated at 10 amps but I don't believe it. It's tiny, and drawing that much current through it will cause problems (arcing, which will eventually destroy the relay). Limit your load to 1 amp or less. 2) Have good, clean power (ie steady voltage) to drive the controller. If you use the same power source for both controller power and load you may have wild voltage swings, which will eventually kill the controller.

## Features

- Temperature controller monitoring instrument, show the measured temperature (red) and set temperature (blue) at the same time. Can be used for cooling/heating control. Operating Voltage: DC12V 200mA
- Measurement Range: -50 to 110 Celsius (-58 to 230 F), the C/F button allows you to switch between Celsius and Fahrenheit temperatures
- Clear Working State: the relay is closed when the light is on, and the relay is disconnected when the light is off. It has high temperature protection.
- With a waterproof NTC (10K 0.5%) temperature sensor probe, rogrammable heating/cooling mode, delay start, high temperature alarm, Celsius/Fahrenheit mode, etc.
- Can be used for fish tank water temperature control, incubation field, equipment cabinet, air conditioning system, temperature control protection, control cabinet cooling system and other DIY temperature control systems.

## Questions & Answers

**Q: Can this be used to control a small 12v heating pad to keep the lithium batteries in my RV above 32 degrees (0 degrees C)?**
A: Yes.  I would use the 12v model so that it connects direct to RV DC system.  Use output of controller to control coil of another automotive relay, that second relay ultimately applies power to heating pad,  Why this method?  If the controller goes sideways, you can always use a switch at second relay to turn on manually.

**Q: do you have a temperature controller for high temp k type thermocouple**
A: Any of our controllers can use a high temp K type thermocouple.

**Q: How does the range setting work? I want power on at 33 degrees F - power off at 35 degrees F**
A: Set P0 to H, for heating. P1 to 2 and the setpoint to 35. cutton is temp setting plus (differential P1)setting.

**Q: Does this device hold its settings during a power loss?**
A: Yes it does.

### ⭐⭐⭐⭐ It does control the cooling fan and provide overall temperature readings inside inclosure.
*by C***K on October 25, 2022*

I installed this temperature controller inside my self built home generator to monitor and switch a heavy velocity radiator fan 10 amps 12 volts on, to control heat buildup. It preformed perfectly as described. This controller held up for 4 months average to 6.7 hours at different times generator was needed and during a couple test runs. The last time I test run the generator, it failed to come on during engine run time. I assume this device is the same as the digital RPM display I purchased and went through 3 of them one right after the other. I discovered that although the manual claims to operate on 12 volts. That maybe true under certain conditions. The temperature controller states that it will function up to 14 volts. In order to correct the failure I had to install a 9 volt regulator in line with the RPM counter and a 12 volt regulator for the temperature controller. Both regulators have over voltage protection so if the regulators are damaged due to over voltage they shut down. I strongly recommend voltage regulators on devices that are installed where an alternate charging system provides power to keep battery charged. Other than this issue Ive ordered 2 more of the temperature controllers and 2 of the RPM counters for spares. If they continue to fail, I will have no other option but to find another product that will preform and last.
