Inkbird controller with JBJ Chiller Help Please

[131696]

how do I turn on the compressor on JBJ chiller with Inkbird controller? it turns on the chiller but compressor don’t come on ,do I have to unplug the thermostat on chiller or somehow rewire the controller it to compressor.or is it a setting on inkbird please help.I got 3 min delay on Inkbird controller for compressor but it don’t come on.and yes the chiller does work and compressor

set the temp on the inkbird to desired. the 'on' temp of the chiller must be lower say by a degree or 2. also make sure both are calibrated about the same.

I want the controller to turn on the compressor without the chiller thermostat.thats why I bought the controller to control it better. plus the thermostat on chiller don’t trust it .need the controller to turn on compressor when I say to turn it on with the controller

I would suggest doing it the opposite way. I first calibrate the chiller temperature probe to sync up with my Apex temperature probe (in your case, the InkBird). Then I let the chiller function as it was designed to, letting it’s onboard controller turn the compressor on and off. I then set the Apex boundaries for redundancy and failsafe protection.

Dont have apex ,i have inkbird controller. Maybe for xmas might get lucky and win 1 ..lol.i just need the controller to turn on compressor thats all .how to wire it up to do that?

Understood, so you program your InkBird like you would program an Apex outlet.

Let me explain... Make sure the InkBird temperature probe is reading your tank temperature. Plug your chiller into one of the InkBird outlets. The InkBird will display a temperature reading and the chiller will display a temperature reading, so you’ll need to calibrate either the InkBird or the chiller, so that the temperature readings are identical on the displays. Now set the chiller temperature at 79 degrees. For my chiller, a JBJ 1/10, this means that the compressor will kick on at 78 degrees and stop at 79 degrees. Now program your InkBird outlet to turn the chiller on at 76 degrees and off at 75 degrees.

By doing this, you’re letting the chiller controller turn the compressor on and off. But if the chiller controller fails in the on position, continuing to cool the tank, the InkBird is the failsafe that will shut the chiller down when the temperature hits 75 degrees. Let the chiller do its job and run the compressor and let the InkBird serve as the insurance policy.

The thermostat,board is messed up on jbj chiller dont work.Please read from start.need controller to turn on compressor without help of chiller.bypass chillers thermostat

 

[131696]

I know theres a way to rewire chiller so it will do this

Unfortunately, methinks your only option may be this...

JBJ Arctica JBJ Arctica 1/10,1/5,1/4,1/3 HP + Commercial up to 5 HP Chiller Replacement Controller (DB-C-3P)

Controller for your Reef aquarium to keep everything running smoothly in your tank.

Perhaps @Brew12 can offer some advice with his electrical expertise...

Ill just send inkbird back ,it dont do like it says or what others say on forums. Wonder if Ranco controller will turn on compressor.i want 1 degree differance how hard is that? 77 to 78 back to 77 .this is turning into a nightmare build

 

[Dr. Dendrostein]

I build and service chillers, and commercial refrigeration. To by pass your controller in the chiller. You need to provide us a schematic of chiller. If dont have or can't get. You'll need a refrigeration service tech. with years experience,come to your home, all the young ones, will have no clue what to do. Today's schools are trash

Just built a $1200 1/2hp chiller, out of window AC, For $123. I had most parts

Have you ever opened up the chiller controller / thermostat to see how it’s wired? Here’s a single stage Ranco wiring video that might help...

 

[131696]

That just the board need the thermostat also. Just need a controller for the compressor thats all .thats why they make external thermostats for this purpose.if they dont turn on compressors without help of chillers then there useless to buy to me.

 

[131696]

So now im getting a ranco controller. Chiller is a jbj 1/5 for electronics diagram

 

[131696]

Will the ranco controller video turn on a compressor on a jbj chiller without help of the thermostat on chiller?

 

[Water Dog]

Find a schematics of your chiller... @Dr. Dendrostein said he may be able to help you if you find
him the schematics of your chiller.

 

[131696]

Ok Thanks

Look what I found... I’m no electrician, but I‘m thinking that this can somehow be done with a single stage Ranco.

Let's just say that was the schematic, all you have to do is disconnect the plug, that says, connector male 3P, wire nut 1 and 3, that's it. Close up chiller, with out controller, chiller stay running 24/7.
That's where a Ranco or Inkbird comes in.

@Dr. Dendrostein Nice!
