Ehiem Jager heater Help

[fishkeeprian]

Hi,

Is there a way of resetting these heaters. I have been messing around with the calibration settings and its not right so i would like to get it back to factory settings to start again.

Thanks

Get a bucket of water, stick the heater in with a thermometer...once it's at a stable temperature, move the red dial to the corresponding blue dial temperature and it's now calibrated. Then test it

My advice is to buy an external controller such as a ranco, and plug it up to that. The internal thermostats on these submersible heaters are notoriously unreliable and will fail eventually. Considering that a heater malfunction can and will crash the tank, its a point of failure that needs redundancy.

The best way to handle this would be to use a ranco, and wire it up with a surge strip. Then use multiple heaters so you have redundancies if one of them fails. This has actually saved my tank once and I would never run a stand alone heater ever again.

Currently I have mine set up with an apex junior and a two stage ranco. I have the apex jr set to turn the heaters off at 81 degrees and turn a fan on which is pointed at the sump at 82. The ranco is set at 80 degrees and fluctuates 1 degree. So the highest the ranco will let the water temp go is 80 and the lowest is 79. I also have an emergency heater plugged into another outlet on my EB4.

If the thermostats on the submersible heaters stick on (which they usually do when the heaters fail) the ranco prevents it from being an issue since the internal thermostats aren't being used. If something happens the ranco gives up the ghost, then the apex will shut the heaters off and notify me if the temp hits 81. If the temp goes lower than 78, the apex will notify me and turn on my emergency heater. Even with all these redundancies, I still had a heater mishap, so that illustrates just how important it is.

I know this wasn't the answer to your original question, and I apologize. I just need to stress how very unreliable hobby heaters are and just how important redundancies are.

So to recap my tangent here on how I think you can fix your setup better and not rely on the heaters internal thermostat:

1: Buy a ranco off of amazon.
2: There are a few youtube vids on how to wire it. Its ultra easy. Use a surge strip to wire it so you have multiple outlets.
3: Use multiple heaters on the ranco so you have multiple redundancies in case one dies.
4: make sure the whole thing is plugged up to a GFCI/AFCI breaker.

There isn't really a factory reset, so-to-speak, on the Jagers. They just come pre-calibrated, so if they end up being a little off, you just have to re-calibrate with the red arrow. As suggested above, I'd get a 5 gallon bucket or something similar and see what temp it keeps the water at and re-adjust as necessary.

I recently just re-calibrated mine in-tank in my 75 gallon.. it was getting the water way too warm for my style.. 84.. i unplugged it, let the tank temp drop to 76 and changed the temp to point to 76, plugged it in... seems to be working now. (might not be a great idea to do that if the temp will change quickly and you have sensitive things)

Get a Ranco! Worth every penny.

Which controller did you get?

I can't get the Ranco in the UK so I went for the STC-1000 its accuracy is +1 degree is this ok, I have included a link. I wasn't sure if I had to wire my Ehiem heater directly into it so cut the plug off strip the wires back and wire it in or attached a UK 13AMP uk socket and plug it in that way?


What do you think?

There are some good video's of setting up the Ehiem jager heaters on Youtube.

Holy crap! 14 bucks? That's great. Lemme see if I can find a tech sheet somewhere on it and help you out? Have you got the unit yet? Does it have a manual or diagram? Could you take some pics of where it needs wired and of the manual/diagram if there is one?

Edit:
I checked the brewing forums and apparently they use this unit for fermenter control pretty regularly. Here's th video on YouTube that everyone keeps posting for reference:

Just got your PM.

That unit will work fine. Buy another heater and plug it up as well. Chances are both of them won't fail at the same time. So when one goes, the other will still heat the tank.
