## Description

This is a DC 12V Fahrenheit Digital temperature controller. It can control the power to a freezer to prevent it from getting too cold, or control the power to a terrarium to prevent it from getting too hot, maintain a stable environment. This controller provides heating and cooling modes and temperature alarm function. For example: If you choose heating mode, set control Value to 100°F, set span value to 10°F. The relay will be connected when temp drop to 90°F. The relay will be disconnected when temp reaches 100°F; If you choose cooling mode, set control Value to 100°F, set span value to 8°F. The relay will be connected when temp reaches 108°F. The relay will be disconnected when temp drops to 100°F Specification: 1.Power supply for the controller: DC 12V 2.Temperature unit: Fahrenheit, Measure range: -4 ~ 212°F 3.Temperature measure resolution: 0.1 4.Accuracy: ±0.5 5.Working mode: Heating OR Cooling mode 6.Slew range of temp controlling: 1 - 25(Max temp span between ON and OFF) 7.Control resolution: 1(Minimum temp span between ON and OFF) 8.Power consumption: less than 3W 9.Relay contact capacity: 10A/250VAC, 10A/110VAC 10.Data retention: Yes 11.Compressor delay protection: YES 12.Product size:8.5*7.5*3.5cm / 3.4*3*1.4in 13.Sensor Cable length: 3m/9.8ft Package Content: 1x Digital Temperature controller

Review: i am using to regulate the temp in my lithium battery housing, these are in a space that will go down to below 0
Review: This is exactly as described and worked perfectly the very first time I wired it up. Use case: I had a car audio amplifier under my rear hatch floorboard powering a subwoofer, I think it had far too many overheating cut-outs until it gave up. I replaced that with a larger amp to now power TWO subwoofers, one remained under the floor and the other is in the open area in the back. I installed a 12vdc brushless fan to blow on the underside of the amp, and when I first got everything running, I noticed the fan is a LOT louder than I had hoped, so I bought this temperature switch. I wired it up so that the power to the fan instead went to the temp switch, then the unit's switched leads supplied the (+) 12vdc to the fan. I changed the settings for this video to show what happens when setting "d" is at 2°F and the target temperature is 73°F ... The amp's temp slowly crept up to [Target]+[d] and the fan kicked on and I watched the temp drop to 72.8°F before the fan kicked off. I then let it cycle through one more time to 75°F, fan kicked on, temp continued to creep up to 75.2°F before starting to fall back down, to 72.8°F and fan turned off. That was proof enough that this thing does exactly what I intend, and I now have it set to kick on at 100°F and run until the temp probe reaches 94.9°F (target = 95° and d = 5). The only complaint I have is that the programming is a little convoluted. I did not explore any settings beyond Target, d, and mode = C (for cooling, opposite of H which is designed to switch on a heater to get temps up when the probe gets too cold). I will update this if the unit fails within the first year of use.

## Questions & Answers

**Q: Can the sensor be submerged in a water tank to read water temperature?**
A: I sealed the sensor at the end of the wire inside a 4-inch length of heat-shrink tubing and sealed the ends with silicone.  I use mine to turn a heating element on/off during the winter to keep a small livestock water tank from freezing.

**Q: can the sensor wires be lengthened**
A: Simple answers: It uses an 10K NTC sensor that can be lengthened up to 100 feet with 18 gauge (AWG) SHIELDED wire. Up to 10 feet non-shielded.

**Q: Can you turn it on and off?**
A: Yes. You can turn it on and off. Press the button "Rst" to turn it on/off.

**Q: How do I switch between cold and hot mode**
A: Just change the HC value. HC=H for Heating Mode. HC=C for Cooling Mode
1.Press SET for 3 secs, HC appears on screen, release SET button
2.Press SET once to enter HC parameter
3.Press UP/DOWN button to select C or H, Press SET once again and back to HC(main menu)

Good instructions if you read schematics and understand basic electronics. (I you do not, don't buy this!) The output is for driving a relay coil or other simple LOW CURRENT circuit. Installed in a sheltered but unconditioned locker in a travel trailer, it has been running a water tank heater for months with no problems.
