That looks a bit naff, a single 92mm fan that looks cheap & nasty not a very good blade design. Fixed temperature control so can not be adjusted to suit the fridge installation, might as well throw your money in the bin.

@Rob Turner -or @Lenny HB I'm thinking of getting the same controller. Does yours 'remember' the temperature setting when it's powered off or is it powered all the time? The reason I ask is that the easiest place for me to position the controller is in the back of the fridge (so not easily accessible) and I am thinking of having an off/on/auto switch accessible from within the motorhome.
With this in mind, I really don't want to be having to change settings on the controller every time I switch the thing on!!
Thanks,
Bill

This is the one I have ordered and it says it comes with a temperature sensor.
Well although I have ordered one it is not despatched for a week or so as out of stock, yes the fans go in the top vent but the temperature sensor wants to be high up as well on the basis that hot air rises, I will start a thread when it arrives so keep your eyes peeled.Hi Martin,
Decided to email the supplier re. the above as I had some spare time and this is their reply:-
This kit is including;
> frame with 2 ventilators + an integrated temperature sensor, so the sensor is on the frame.
> remote control with potentio meter, so that you are able to “program” the temperature on which the ventilators should go on (in automatic setting). Plus you can switch to manual.
I am really confused now as my understanding is that the fans should be located in the upper vent and the sensor near the absorption unit unless I have got this back to front! Looks a really neat unit so really keen to understand how this might work!

Sorry @Lenny HB but I've another question! How deep (front to back) is this control board? It's just that the plastic project case I'm looking at is 85x56x24mm. I'm not sure that the 24mm is sufficient.If you are going to mount it behind the fridge (I did that on my last van) might as well use and once set up put it in a plastic box.
Just used one for my internal fridge fan approx 48 x 44 x 22 it gives dimensions on eBay link.Sorry @Lenny HB but I've another question! How deep (front to back) is this control board? It's just that the plastic project case I'm looking at is 85x56x24mm. I'm not sure that the 24mm is sufficient.
Bother - sorry, I've just remembered that this was for your old motorhome. Can you recall roughly how deep it was?
Thanks @Lenny HB - on the link I was looking at it only gave the 48x40, not the depth.Just used one for my imteral fridge fan approx 48 x 44 x 22 it gives dimensions on eBay link.

Yes but those vent clips break easily (I've broken them in the past) and the vents are expensive also can be painfull on the fingers. Much easier to fit fans and forget no messing about taking vents out every time you stop.I had recently considered fitting fans to the fridge vent, however whilst touring France last year, we were camped next to a French couple and I noticed that they had removed their fridge vents, later in the day we got chatting to them and it transpired he was a refrigeration engineer in the Champagne industry, I asked him why he had done that and my idea of fitting fans, he informed me that just removing the vents when stationary was far more effective than fans, and he in the course of his work done much research and tests on both methods, hence why he had just removed the vents...I emulated his method, the rest of last summer we had no issues with a 'warm' fridge and we are currently in Croatia where daily temperatures are in the mid 30's...the wine and beer are wonderfully chilled...
Used them in the past on caravans but never had any luck with them on the big fridge freezer uints tried variuos temraturers.. The hysterisis far too wide, the 40 deg ones don't normally switch off until the temperature drops below 25 deg so the fans are running permantly.I don't really understand the need for switches or adjustable controllers. The switching temperature isn't critical (just error on the side of early switch on) and only needs to ensure the fan doesn't run at night. Fixed sensors are cheap and wiring is simply. I use one of these.
I can't remember what switching temperature I chose.
You're quite correct - I've been looking for something better for a while although I'd still prefer a simple 2-wire device.Used them in the past on caravans but never had any luck with them on the big fridge freezer uints tried variuos temraturers..

Paul,I think it's likely that your controller is switching the 12 volts across from the 12 volt input on the 4 way terminal block to either K0 or K1 or both.
To test, check for 12 volts between GND and K0 when the LED is off and there should be no voltage and the the same (between GND and K0) when the LED is lit and there should be 12 volt.

You trying to confuse the poor man.If the default mode is cooling on the controller, it will complicate things a little but the handy little relays have a set of NO and NC contacts and the temp controller circuit can be used to switch the controller operation around to heating mode.
