$20.00 Controller-how to wiring (easy)

[jawfish]

Have you looked at the one with a 20 amp model ?

It gets better and better. Thanks to Rick for all this info.

I am running 2 heaters (500W & 300W) with separate controllers in the sump for 300G tank. Each Controller can handle up to 800-1000W but I decide to run 2 to cross check temp on both controllers and just in case 1 fail, the other back up. I place both titanium heaters in last chamber where the pump pushes water back with the returns on both ends into main tank and temp probes place in first chamber other end of sump where drain water from main tank. I am not sure tanks are not cover the top or lid but i cover mine and temp is stable so far.

Just out of curiosity, do you have the probe set in the sump or in the tank?

Probe is in the sump and my digital thermometer is in the tank

Really Nice write up Rick, I'm a huge fan of DIY projects and I'll definetly be referencing this one down the road. What a great project!

I don't know, You and Paul have been churning out these "How to" posts left and right!

Had a heater cook all of my year old galaxy Turquoise last night. Will this prevent that?

yep, the controller will shut power off to the heater at whatever your preset temp is, it could happen again though if the controller were to fail along with the heater at the same time but i would say thats a longshot to happen.

You just saved me a pile of money with heater controller how to. Very cool.

Chances are a controller "fail" would result in a no heat situation as opposed to a always on heat situation.

THANK YOU!!!!
I was just about to order a name brand controller for $60 and I got two for half that. Thanks again!

These are a great controler I haven't had an issue with one either very reliable and easy. You can programe them to not exceed a set temperature range or go bellow a certain range either. Just don't over load them.

Good post . Think I'll try this

Here's a question. I need my tank to stay between 83 - 85 so should I have heater set on high side of like 86 and controller set on 84 +\- 1 degree?

Set controller at desired temperature and heater one or two degrees above.

I would assume you could turn the heater all the way up since the controller is going to shut is off at the desired temp.

Hey Rick,
Have you found that the controller is fairly accurate out of the box or have you had to calibrate them? I just completed my first two and the temp the controller shows is a little low compared to my infrared thermometer. Guess my thermometer could be off but wanted to find out what you have seen with yours.

Thank you
