Trying to remember how this was set up after update erased settings. I cannot remember and i've been told eight different ways to sort of accomplish this by different people.

I want chiller and heater to run without ghl control unless either malfunctioning. Specifically, I want the heater off at 78.5F, an alarm at 78.5F (or 76.5F), and the chiller off at 76F and 84F.

Right now, I have one temp probe and three virtual probes.

Temp probe #1 for temp too high, and alarm on. Alarm goes off if the temp goes over 78.5F.




(Virtual) Temp probe #2 for if chiller is stuck on chilling too much, no alarm. I want the chiller off if the tank temp hits 76F.

(Virtual) Temp probe #3 for chiller stuck on but heating tank, no alarm. I want the chiller off if the tank hits 84F (rare if caused by chiller but can happen).

(Virtual) Temp probe #4 heater shut off. Heater is shut off if the temp hits 78.5F. I have a "cooling difference" of 1F but god knows what this does. I can't find anything anywhere actually describing this function. The hope is this some how keeps the chiller and heater from being on at the same time. But i have no idea how or if this works. Or what setting it should be at.


Programable logic to effectuate the chiller being off if tank too cold or too hot:

Note: this isn't working? What am i doing wrong?

"Switch channel" for chiller:

So, anyone that understands all this, what i am doing wrong here if you do not mind explaining?

Thanks!
 
I do not understand this at all - you have started two different threads with different scenario for the same task. Can you please take away one of the threads and describe your problem as it is in reality

Well before i updated my controller's firmware i had asked for help doing this exact thing. Between Vinnie, you, another, and a local buddy i thought i had it set up. Then i updated by firmware. Lost all of it. I was irritated, not motivated to try to setup this software again (its a half day task usually or more) and left it alone for a few weeks. Finally i am trying to get it set back up. I have no idea how it was setup and just guessing at how i did it before. This is not stuff that is easily remembered. ... So i posted this thread. Why can't i post a new thread? You've helped and i appreciate that a lot. But i also understand its a huge time suck to work on GHL programming, let alone for another person, so i totally understand if you dont' have time to help again
 
So cooling difference is:

When you want to exceed the hysteresis value by a few degrees (whatever you set the cooling difference to) before the chiller comes on? Correct? Thank you!!

I have a hard time the with the german to english translation for GHL. It's like reading a paper/letter from an exchange student in college; you ultimately get what is stated but it's definitely not stated in very common vernacular.

You may have figured this out already, but the controller has a feature to download and save its settings. That way if you do need to restore them for any reason, it's a simple upload. You do however have to re-enter the virtual probes from the front panel. For those you can save screenshots of the settings, so you know what they were and can verify that they restore properly when re-entering them. That's what I do, and I save the settings after every change I make.
 
Local buddy figured it out. I had the temperature 3 virtual probe set to cooling but since this was a shut off for a chiller that was (malfunctioning and) heating it needed to be set to heating (or hit "invert").

Last, the "or" function in programable logic 1 would not work for this. CHanged that "function" to an "and" now it appears to work when i test it; A very low temps the chiller shuts off and at very high temps the chiller shuts off. Everything in between the chiller regulates its own temperature.

For this brief moment in time, i feel like i 90% understand my settings here. The trouble is that in a few weeks or months, there is little chance i will remember. Hopefully it comes back to me if i need it to. The GHL is for sure its own hobby.. lol

Backing up now so i don't have remember, maybe! lol.
 
Does anyone know how to program the GHL so that the chiller and heater will never be on at the same time?

That's my loose end on this programming. ..

Could be as simple as heater outlet and chiller outlet never have power at the same time. How do i do that?

To be frank - it is not a question of time if I do not help you again - I´m retired. It is more a question of your total disrespect for GHL in another thread that make me think if it is worth to help you with your setups again. If a lot of people have help you to set up the program in an earlier thread - and that you want exactly that setup - why do you not just go back to that thread and do your setup the way it was described there.

You must respect the GHL :D

You're hilarious. I am sorry you're hurt that i don't like GHL. I didnt realize i was mandated to like or respect GHL. I mean i bought, i have it, i use it, but no i dont particularly like it....i borderline hate it. Certainly would not recommend it without strong words of caution. Mostly that its for people that want another hobby... learning GHL programming....it's kinda like a lemon car, you're just stuck with it until u ditch it.

I understand you have a profilux 3, have used these for years, speak a couple languages, and at this point have mastered the programming. Not everyone seeks to be you. Some of us just want a controller as a time saver and to protect our tanks if something fails. GHL for me has not been a time saver. Its a huge time suck. Like i said its another hobby of its own. It may save my tank but im not clear there because when you only speak 50% of its language can you be confident in what you're programing?

The prior thread doesnt have in it how i actually set things up. It has several suggestions. It wasnt until csund came over and helped me dial it in that it was set up. He is very good at this. LOVES GHL. We're still friends. My thought is that we never even set it up right the first time. We had the "OR" function in advanced programming. We needed an "AND". So, no, the prior thread was no help.

Moreover, he is very good a programming GHL's, a HUGE fanboy like you, and we still initially got something as simple as emergency shut offs for a chiller programmed wrong initially.

The point being, and word of caution, for GHL users--be careful programming and test everything after thoroughly--because its not easy software to use or setup.

When GHL says that its easy to program, that's either a lie or a gross over confidence in their products ability to be used correctly by the average person. Again, you're not average. Your like a super human with GHL. Us mere mortals are pale in comparison.

Sorry to burden you with this extra thread. Its probably taking up too much harddrive space on your computer.
 
Cooling Difference, using the same Temperature Sensor to control the Heater and Chiller.
So ultimately it was csund's conclusion that cooling difference cannot be used to prevent the chiller and heater from coming on at the same time if one was malfunctioning, at least not where i am having the chiller and heater only controlled by ghl when extreme temps are hit.

In other words, if the chiller malfunctions and comes on when the tank is set to 77F (when it shouldnt) but the temperature of the tank is actually 76F--both the heater and the malfunctioning chiller will be on....

My only solution would be programming that said both the heater and chiller outlet cannot be on at the same time.

This was easy to accomplish on my previous aqua controller jr.. if heater outlet on then chiller outlet off..

But so far crickets from GHL--in all its supposed superiority--in being able to do this very simple and pretty common programing??

If the chiller and heater are being controlled by the same Temperature sensor with a cooling difference what possible failure mode would cause both heater and chiller to be on at the same time?

They are not controlled by the same temperature sensor. The whole point of my programming was to have the Chiller's temp sensor control it and the heater's temperature sensor control it. GHL only steps in when one malfunctioned and the temperature, as determined by GHL's temperature probe, goes outside that wide range (76F to 84F) into dangerous terrritory.


In other words, i don't trust GHL to control my heater or chiller and don't think its good for either the heater or the chiller. I want the devices to do their thing. GHL is a back up for failure.

Unfortunately, if one device fails and stays on when it should not, the other device may be running too.

What i want is a command in GHL that says if heater on, chiller off, and/or vice versus. Then the temp will go up or down based on the room temp, and i will get an alarm and correct the problem.

I can't seem to be able to do that.
