We go through our off grid sap sucking system and how we built it. The link for the what I used is www.instructab... but I did make some changes for our application.
I am a little confused, well, sometimes that is an understatement. LOL. Why do you need a car relay when the temp controller has a built in relay? I have seen this before on some other videos and was wondering. I have this same setup but without the car relay and have had no problems. Just curious why it is needed?
I followed the plans that I found online and they called for the the rely which my guess is for the higher amp rating. The Temp controller is only rated for 10 Amps the relay is 30 amps so it just builds in a safety factor, to prolong the life of the temp controller. But if yours works without the extra relay that's good to know for the future.
Yeah, I thought of that too. The pump is only rated at 7.5 amps so I figured I was good. If it blows up, then I guess I should have used the extra relay.... :)@@kalevalasouthfarm
