fan speed controller

27 posts in this topic

hi,

 

iv been looking on ebay for a fan speed controller but there's far to many to chose from so i'm looking for recommendations please....

 

i'm looking for one that's got an automatic temp control on it and it has to be silent, i have £150 to spend on it but if there's a decent one for cheaper that would be great...T.I.A

The sms twin controller does everything you want it to. I can't confirm that its completely silent but it should do the trick depending on your size and circumstances.

I was really paranoid about mine to begin with, as I haven't done a grow in a year or so.. but now i walk into the house and don't notice it. 

The room its in is at the top of the stairs facing the staircase and I leave the door wide open time to time.

 

Also there are 3 generations of the SMS controller so if you go to a shop with the newer one or 2nd gen, you may be able to haggle them a little on the price of an old one.

 

One thing I would say though is dont buy a used controller make sure its brand new as I have a Gen2 and a gen1 and the gen2 seems to cause 4in inline fans to destroy themselves..

 

Let us know what you go for! I don't think SMS controller is a variac though...

I note that if you google those controllers you get a website as well as ebay selling them. I am an electrician and would have no trouble building one of the controllers in the diy section......BUT watts has run out of the 1amp version so im looking around. (Background - I am currently in the early planning stage of getting a list of stuff together.) Hence why I am having a look at this part of the forum.....I have lurked for about 6 years....lol I like to take my time hehe.

i never got a reply so i just bought it mate, i still don't know if it was worth the price though as i don't understand fully what it is lol, its just an electronic thermostat and an auto transformer(whatever that is) inside the box, you set the temp you want and the fan speeds up or slows down to stay on what its set too, there's no variac inside it and you can't manually slow/speed up the fan...and you can only wire one fan up to it.

Is there any sort of seperate temp probe or sensor?....if not then it's built into the unit.

You will have to fiddle about a bit to find the right position in the growroom to get the best results.:yep:

That's good, you can mess about positioning the probe to find the best spot. I have mine close to the roof and out of direct light, works a treat.

Good luck with it bud:yep:

i'm only 2 weeks away from harvest and everything's doing ok for now mate so i don't want to change anything while everything's fine, i was going to set it up properly when the tents empty... 

 

i'v only done the wiring on it for now, the fan entry point iv just put a single socket coming from it and when it's time i'll just put a plug on my fan instead of wiring it straight to the connector, i'll also have to set up all my ducting properly, iv got new stuff their but iv just never got round to changing it, so i'll have quite a lot to do after this crops down.

Got 2 of them - they are really good. You can either leave controller to adjust the fan speeds automatically or you can set the desired speed by changing some wires inside. The guy from smartus uk explained me how to do so. You need to change wires inside, straight forward but can't remember a thing now - it was over 2 years ago! Both controllers still works fine and there's no hum from fans!
