Dear @@robojax, I have installed the device as a humidity controller and I'm having some problems. Maybe you can point me to possible causes. It has been 6 days since it's running. It fires at 75% RH and turns off when reaching 90% RH. Yesterday, I woke up seeing the RH at 106%,. The ligth on the STC-3028 was off and yet, the humidificator attached to it was still on. It seems the relay did not stop the electricity! When I vent the sensor off and I make it reach 75%, it starts again, and reaching 90% it stops and no, it works.. But every once in a while, it fails again... Any thought on what could it be? Factory defect? I'm connected to a 230W socket (this is now Spains voltage) and I wonder if that might be the problem. .

Thank you so much . Very well explained .

REALLY good review, appreciate the detail and tips without being too much.

Love the fact that this is in English, as most for this are not and that you're Canadian, as am I and you did a great job explaining this device. So you earned a like and sub from me. But I wish you had showed all of your wiring for every demonstration. That's the most confusing part of this thing for me, not so much the functions, but that's also highly useful and helps me learn the device better. Other videos in other languages showed their wiring, so between theirs and yours it should be fairly straight forward, I think.

@@robojax O.k., fair enough. Maybe I missed something. It was late and I was getting tired when I watched it. So admittedly, I may not have been paying good enough attention. I did see you go over wiring, yes, on one device (the lightbulb I believe). But the others, you just showed already hooked up and then proceeded to explain how the functions relate to that device you hooked up. What I meant was, I would have liked to see how every device was wired to the unit, as there are multiple ways to wire and configure this thing. Like the option of powering them all off the same power supply vs. each thing having it's own supply, like the wiring diagram shows can be done. And you did explain that every other device you hook up to it, works similar to how the lightbulb is wired, but I am so green when it comes to electrical and this stuff, I need detailed demonstrations of everything. Yours is still the best video I've seen on functions of it and how to approach wiring it, it was very logical and one of the only few videos in English about it.

Thank you for a thorough tutorial on an STC-3028. I just bought an STC-3028 from AliExpress under US $7 + Free S/H to US. If you don't mind, I do have a question in wiring this item. In this case, I am using a polarized extension cord to wire my STC-3028. The question I have is whether it is OK to use the (-) line as a pass through and the (+) line as the controlled line to connect to the S1 (temperature) and S2 (humidity) port.

👍👍

Great video, thanks. Could you advise if we can have leads from both temperature and humidity to a single fan? Not sure if it would back feed and break the unit? Thank you.

Great video and so well structured. Thabk you! What would happen if I connected SHT35 sensor instead of the one that is included? Would it work? I'm looking for better RH accuracy :)

Awesome video thanks! So this cannot be used to control both heating and cooling simultaneously, ie turning on/off a heater within a certain range as well as turning on/off an aircon for cooling within a certain temperature range?

Hi thank you very much for an excellent video. My stc 3028 works perfectly. only problem I have which is a significant one, is on the RH setting when it reaches 100% it deactivates the RH relay . I can't find or change any settings to prevent this . the controller works absolutely fine on temperature and Rh but if it reaches 100% humidity the controller clicks off the Rh relay . This pretty annoying and I'm unable to solve this. any help would be appreciated. Also there's a setting range not shown in your video for p0 P1 P2 and P3 which are alarm limits and time delays but these do not affect the maximum RH value from cutting off the relay thanks again. Peter

Sory i subscribed and 2 times thumb up!!

ello, great video, yet i still have to understand if it's either cooling or heating and, mostly imoportant if i need a relay or the unit itself acts as a relay? tanks

Hi, you made me watch the video and in the fist 15 seconds I mentioned that “you can use it as heater OR cooler controller “ so I mentioned OR and perhaps 20 or more times. Now the relay is inside it. You just need yo make two wires from your heater or cooler to connect.please watch again as I can assure you that you should not have may questions after carefully watching it.

You 'd better look further. I just bought the 3008 version. Red channel did not switch (always on regardless status of indicator light). When I tried the blue channel it said SPAT! and the fuse in my distribution cabinet was blown. Yes, I wired correctly. It is dangerous junk.

Maybe it's because of a false signal induced by the wire of the power supply. When that wire is too close to the wires of the sensor, it may induce a low current through the sensor's wire. Since electronics function with little power, that could be the problem. Prolly a bit late to the party 😂🎉
