RIMS using Grainfather Connect

Hello all!

I’m looking to finish off my RIMS system and was looking at potentially using the Grainfather connect as a controller.

I have a couple of questions if anyone has experience doing this...

I currently have a 2400w element in my RIMS tube - as the GF connect regulates the power sent to the element is there any issue using the 2400w element? I know the connect is only rated to output 2000w and I wouldn’t mind just buying a 2000w element if it will cause issues with the unit.

Is it possible to open up the unit and replace the temp probe so (an electrician) can install a probe with a longer wire?

I would also be hoping (for an electrician) to cut the cord that runs to the pump and install a female power socket so I can plug my pump directly into it.

Any help would be greatly appreciated!

Cheers!

 

You can get a plug adapter that'll let you plug pump right into bottom. I would stick to the specs it has for the element. Would be good to do the same for the pump, i think i i remember someone hooking up a bigger pump and it tripping the unit.

 

Tried this out with a march 809 and a 240v 4500w (running 120v so 1125) watt element, seems to be doing ok.

 

Cheers pbrennan10, looks exactly like the sort of thing I am trying to rig up. Maybe I’ll get a lower wattage element and give it a crack.

 

Loaned it out to a friend and he used it once with great success then about 30 mins into the second brew he said it stopped heating. I think it may have just been the fine tuning phase of the temp control that the grainfather kicks into when within 4 degrees of target (SSR?). Have taken it apart and tested it and everything seems to work fine. Any ideas?
