W3230 Temperature Controller

Works excellent controlling fans in the caravan fridge in hot weather set at 39° with a 4° waiting works perfect

It’s a small unit and could do with being a bit bigger. Easy to wire up but not so easy to configure. I purchased it for heating control of a a PTC system. Once it gets to 40 I wanted the relay to switch off. Simple enough in theory, but difficult practically. I managed to sort it by just playing around with it over half an hour in the end. For £10 a budget, entry level unit that works well, just difficult to setup.

After a shaky start due to total lack of instruction, I was about to give up when I found the attached diagram. Basically, I had just wired the 12v supply directly to VCC & GND which did supply the power for the controller. It allowed me to program everything etc. Try as I might, having connected my fridge vent fans directly to S1 & S2, I could not get the fans to work? I assumed, wrongly, that a ‘bridge’ was built into the PCB? Not the case, so wired like the schematic shows, had all up and running in no time! Very pleased overall, can’t comment on longevity of the unit but for the price, a good solution to help keep my fridge running efficiently. The manufacturer also has a website if you search this product description which has a lot more info on setting up all the parameters.

Once you work out the functions it works very well.

Worthless, didn't Wark at all just some lights and that's it. Tested re tested, didn't bother to even claim,

I already had everything I needed to complete a DIY filament dryer box, minus one digital thermostat, with the ability to switch 12v at 2mps. This little cheap and cheerful gizmo seem to suit my needs. I used it to switch a 12v 100w Peltier car heater. I found playing around with the unit revealed additional programming menus not documented. In fact the unit came with no wiring or programming instructions, however a little digging around on Google I soon found a fairly descriptive English manual in PDF format for model W3230, after which programming was easier, but still awkward to navigate using three sketchy buttons. Pro's It's a cheap solution, that once you've got your head around the secret menu, it's a fairly easy and useful digital thermostat. It can be set to operated between a wide range of temperatures. With selectable software based NO/NC operation from a SPST 12v relay. Although it's plastic housing initially appears somewhat flimsy and fragile, once mounted into a panel those vulnerabilities effectively disappear. I needed to maintain a steady enclosure temperature between 65~75 degrees, which it does so without issue. Con's: The status LED on my unit was misaligned with it's aperture, but was an easy fix. The screw terminals are not anchored to the circuit board, excess force can easily damage them. Conclusion: You get what you pay for, it does what it says in the listing.

I installed this in my VW camper to switch on cooling fans to increase the airflow around the back of the fridge - works perfectly, very easy to install and configure and particularly liked the length of the temperature sender lead. Display is easy to view and the power draw is minimal, I have it set to switch on the fans at 25c. Highly recommended.

Does what it is supposed to do but I have a few comments. The instructions show two diagrams for connecting a 12V load and an AC mains load. These are labelled the wrong way round which could be dangerous for anyone who doesn't know what they are doing. The specified load is 20A but the connectors are small for the cables that would be advisable for that rating. 1.5 mm2 is about the maximum size that will fit.

funktioniert einwandfrei

Manque une notice détaillée pour changer les modes de fonctionnement, mais on trouve en essayant...

Va bastante bien, tendría que traer instrucciones de uso en Español, porque tiene truco para programarlo. Pero una vez programado funciona correctamente y es económico.
