I take this time to thank the woman who gave birth to such a son. Man you are a blessing. All your videos are impressive and very informative please keep up the good work. Message frm South Africa.
very helpful video! I purchased several of these about four years ago but need to reset it. your video helped me, because I could not remember how to set it up.
@@anandjoshi8554 well I guess it depends on the project. If it’s Nuclear reactor or a guided missile project, or a human cryogenic freezer then no! But for anything else yes, they work great. I have six of them and they work great.
The W3001 controller available for $3 works quite well, this seems to have similar function except it works off 120VAC, and switches the line to the output. Button user interface is different, with a low and high threshold setting used to control turn on and turn off for both heating and cooling, with the hysteresis determined by the delta between the two settings. Very useful. The cheap version uses thin gauge wire presoldered to the unit instead of screw terminals, so I just changed them to handle higher current. It does come with a housing, so it's more complete and ready to use. Modified one to get isolated contacts to switch a logic level signal rather than 120V.
Well done! Just a safety comment if I may. If you connect a test load as shown in the video be aware that 120 - 240 volts will be exposed on the back side of the circuit board. Use caution, or perhaps test with an LED and a 1K resistor in series with the relay contacts.
I have only one question that no seller can answer, but if the 12 volt DC power is lost, then you loose your settings and have to start again. I am guessing this because they list “Static Current” of less-than 35mA. I looked to see if someone ask the question and watched the entire video as well. As a retired automotive ASE Master Tech since 1978, at 62, I still like to learn, but truthfully want to use it for a fan over my transmission cooler. I enjoy your explanation & the equipment you use and describe your findings. If this was a hobby, I would not own a Fluke 87 V digital multi meter. I tell people asking wiring issues on vehicles to use dielectric grease where exposed to water/moisture but also good grounds and these “Star” washer to dig into the metal. Most forget the ground side on a vehicles chassis and using voltage drop as a diagnostic tool. Thanks again for your clear videos. I am saving this one for myself!
Hi Dean, The settings are saved when power is disconnected. Your assumption is correct on the amount of current. thank you for sharing your thoughts. stay safe.
@@robojax Thank you so very, very much! The “Static Current” they refer to must be the amount of current this device consumes when on, digital display shining, just no “On-Off” activity. I intend to use an external relay to operate my fan. This makes the current requirements on the boards relay very low, actually making its relay last longer, because it operating the coil of an 80 ohm relay. Most eBay or amazon seller do not have the product nor ship it. The payment is sent with my address and is sent form another location. I saw this device will hunting for info on it. You did a wonderful job showing both different voltage and current levels. Even noise on the out put was a bonus, important to some, but will not affect my use. Oh many blessings on your effort as video are work too. It looks like tape would hold down the NTC thermistor when the heat gun is blowing it around. I had plans to place it in the back of my custom console. It would not be fun to re-set it once power is shut off. Once again, thank you so much!!!!

Ty sir robojax... very informative.. very easy to install. Ordered another batch of this device for my incubator projects.. this is very useful for us beginners.. more power sir robojax...
@robojax Hi, I would like to implement, in a half closed box, where my NAS and switch are, who heats pretty much, to throw inside a quiet fan like Noctua 80mm NF-A8 5V PWM with temperature sensor for automatic cooling Initially I thought to use NAS usb but I think external power supply/adapter is better. You think this W1209 would be a good fit for my case?
Thank you for the great video and feedback on the comments. I purchased this controller but didn't use it because I was confused how will it know if the setup is to heat or cool. Things are very clear now.
It's a pretty sad state of affairs when the Chinese know they have us eating off their hands that they don't as much as include instructions on how to use the stuff they sell, forcing us to rely on finding the info ourselves. And still here I am, supporting their economy by buying their junk. Nonetheless I'm quite impressed with this thermostat. It works incredibly well. Question is, how long 'till it breaks down and stops working, like everything else made in that country? Thanks for posting the instructions on how to use a device that could/should have come with instructions. Sheez.
A great way to test the controller is to tape the sensor to an incandescent lightbulb. These lightbulbs get hot when turned on and cool down fast when they are turned off. In the HEAT mode the controller will turn the bulb on and off causing a cool flashing. Don't do this with an LED bulb as they don't get hot enough.
Thanks a lot for the video. I got this for a project of mine and I'm trying to find if it's possible to program it so that the + - increments go by 1 degree instead of 0.1. Also, is there a way to program it so that it is on for a certain amount of time? Thanks again!
Great video. Question: I will be connecting this thermostat to a relay in my truck (12V). When the power is disconnected from the thermostat module (via relay) will the setting on the module remain at MY settings or will they default to a factory setting when relay restores the power to themastat module? Thank you.
What is your opinion about connecting a reverse diode across the Relay terminals, to protect the contacts from potential Back EMF ?? I am switching a 12Volt 1.5A DC Fan, so a 1A rectifier should do the trick. Thank you for an awesome explanation.

Hi, Im just learning about this existing while taking abt a semester worth of time to do exactly what this does with arduino, so that sucks. I just want to ask, if I supply like 5V to the module, will the device work? I just want to use it for the temperature display and not the relay, so do I have to supply all 12V?
Hello, is it possible to connect a heater(polyamide, for instance) and heat something throughout a certain period of time, with a fixed temperature and then it goes off when the time limit is reached?
I have not see such thing. But you can buy very cheap boost converter where you can input 5V and it will boost it to 12v. I have video in that . Search my channel
@@robojax Thanks. I later saw that the solid state relay would work with an input trigger voltage anywhere between 3V to 30V to switch on high (resistive heater) loads, so no worries.

Upper and Lower Limits seem to be the total range in which the module will do anything; and their use escapes me.
For example, I initially tried using the Upper Limit for trigger temperature, and nothing worked. It seemed to lock out the module.
The use for the 'Correction' mode is also not obvious . .... Correction from what ??
