Good evening Homer!
I got notification reminder regarding your post so please let me explain you shortly to your bolded questions/concerns.
My replies are in red, thank you.

[/b]


Just look at the bolded part, then go back and read this thread, the entire thing. Every problem anyone posts about, all they have to tell anyone is this same exact thing. If bluetooth works with everything in my home and anything I want to connect to except your doser, even if its sitting on top of the doser, there might be something wrong with your BT module or coding. Not every damn computer in the world that works with everything EXCEPT your doser.
Im really happy that your BT is working with everything on your home - but still doesn't matter in situation of BT module not support communication protocols included in Class 1 modules and supported in "full" radios included in this modules. If it would be something wrong with our coding - it should be wrong on all computers/devices or we are going way that every Customer have different software/firmware and doser. It's not working like that.




Look your not going to get any response on this forum from anyone at PacSun as no one has been in this thread from them since june.

Please excuse me, as you see we are ready to answer any questions posted by our Customers but we dont have time every day to read all forums. As you can see you don't have to wait too long for my reply.
Additionally - I can only say that's not true that our company is not active in our threads, last answers made by our technical support come frequently on RC - lastly I was replying on some posts on RC in October this year. If I missed any of your question/post please take my apologies.


Anyone buying this should really look elsewhere. I literally threw mine in the trash after 4 months of it intermittently working, then finally bricking itself with a firmware update. There is no way in heck I would spend extra money to send it to poland to maybe get it back working only after several months of no doser. By that time any sane person would just buy another doser and tell poland to keep their giant POS.

I'm sorry to hear that you did it. During firmware update you did probably a very simple mistake which I will explain below.



And YES I will tell anyone that wants to buy this, to go elsewhere.

You quoted some my answers to you:
Ok explain this to me then... Why can I go back to original firmaware with the exact same BT module, yet updates will not take? Must be my BT module right?
It's quite easy to explain. You tried to did a firmware updates using previous version of software(which was including also firmware update option). It was working but limitation was file size - up to 32kB. All latest version are compatible also with Kore 7th and size is much bigger - thats why it require different firmware uploader which is explained on our website(in download section you can find firmware, manual and special tool for doing firmware updates in our devices).
I regret that you not contacted with us earlier (with our support which reply to questions immediately) - they would be happy explain it to you and even assisi in remote firmware update(we did several times for non experienced Customers - completely for free doing also some online training for them). If course, even with weak radio uploading "old" firmware can generate some CRC errors (which occur when there are checksum errors during packets transmitting - mean weak radio in computer not transmit all packets properly)

This is totally not true. Think of windows updates, some fail for some, while the same exact computer owned by someone else installs them without problem. It all depends on whats on the PC prior to the update. Even basic coders know this, and yet you don't?
Please forgive me but we can't take full responsibility for Windows updates if they are not working properly or doing a mess with BT transmission. We try to do our software/code flexible as we can but we don't know what you have installed on your computer. Similar situation was on Mac computers with Maverick software where AirDrop service wasn't working properly after new system installed. Before it was working fine - and after released update to Maverick by Apple - also started working fine. Should we say in that situation that our "transmission protocol" was faulty? Rather not I think. I can post several comments of Customers which had problems which their bluetooth speakers, keyboards and wireless media devices. It was simply something wrong with that version of OS. In your situation - Im almost sure that faulty was Bluetooth module in your computer even if it was connecting with everything (as I supposed it mean mouse, maybe keyboard.).

Please allow me to move your any other post for direct communication with our technical department (if anything else need to be explained).
Tomasz from technical support will wait for your any mails on service@pacific-sun.eu

Hello Sultan!
My replies are below(red):

Hi Pasificsun and All

I am in love with my Kore 5th Ultimate Pack and I am using all options for several months.
One of the best investment I did for my tank.
Thank you hearing that - a specially here ;-)

AWC Improvement Need:
I have only one improvement need or any suggestions to solve are welcome
I use AWC DC pumps when I calbirate DC Pump1 (Dirty Water) it never loose calibration as water level in Sump is stable so the head pressure is not changing.

However for fresh mix salt water DC pump this is not the case as head pressure is changing due to the water level decrease. I am using Vertical Style 100 Litres water tank probably 80cm height 40cm diameter. I observe each 2 days need to reduce the calibration amount approx 10ml. Is it possible to add a ratio for this so it will automatically update the DC Pump calibration? Or Maybe an option to enable Fresh Mix Tank size can be entered and then make some head pressure calculations etc according to water level (percentage of filled level) Now I need to change calibration amount every 2 days.

Hmm, please drop us email to service@pacific-sun.eu with above question./concerns - we will ask our programmers how it can be solved. Are you using latest software and firmware where both DC pumps can be calibrated right? If it will be possible to make any improvement on this from software side we will do it of course!

Looking forward to your suggestions or any other feedback from users if they face same issue.
Maybe I have some issue on the pumps and making some suggestions those will not add value?

Kindest Regards

Thank you!

Thanks Syntax.....the only part of the tubing from my Kore 5th doser that will be touching any fluid is the tubing PULLING fluid from the pump, (the other side of the pump and related tubing ends up in my sump). For example: I dose about 145ml of vinegar a day (carbon dosing) so that container will be pretty full and the tube submerged in the vinegar container. That will be pulled from the dosing pump and exits the pump to my sump. The tubing that ends up dripping in the sump is at least 8 inches from the water level... this being said the only thing that could possibly create a siphon effect is the vinegar. So, if at all, I would think a check valve would go there....do you agree?

My greatest fear is that a siphon effect would end up emptying the vinegar or trace elements or magnesium or potassium container in totality into my sump rather than the prescribed dosing amount......and that's what I am trying to avoid. I'm not sure that when the dosing pump shuts off that a siphon effect is guaranteed to not happen.

If you are worried about siphon effect you can you check valves - however if bottles are placed under the doser and tunings output are above water level - it shouldn't happened

 

[Przemek_PacSun]

Any news about removing 5000ml refill limit, as we have spoken at Interzoo?

I'm still waiting for a new fw....

I found your post now. Can you tell me, if there will be limit up to 6500ml in single container it will be enough for you? With that kind of precision 0.1ml for channel #1 and 0.01ml for all other channels we have limitations for anything above 6500ml..
Please contact with our service for more informations.
Thank you.

Thank you.

The last fw has the same limits of 5500.

For KH dosing, I need 10.000ml or more, but the minimum dose value or precision is not a problem IMHO. Could be 1 ml.

If I dose 300 ml of KH or 298 or 302, is not a problem.
So, if the fw has the possibility of reducing the precision but raising up the container volume at least on #1 head Could be great for me.

I just changed the tubing on all of my pumps. I found tubing that meets your product specifications on the inner dimension, (I was previously using wider tubing...which was working as well). All my pumps in use (4 out of 5) had been previously programmed and calibrated. I have check valves on all the pumps both on the intake and the output. I used the manual dosing module to test all the pumps and all were working prior to letting the unit run as programmed.

Pump #4 was scheduled to dose 50 ml, on Saturdays and Tuesdays only, in 24 increments during the day. Well pump #4 went on yesterday, (Sunday), and dosed about 600ml in about 6 hours time....all the other pumps seem fine. I noticed that the pump #4 container, which is a plastic bottle which holds around 1900ml was "drawn in" or appeared as if a vacuum effect had taken place, (air sucked out of the container). None of the other containers, which are all the same, had this issue. Could that have any effect on the amount dosed?

I am going to check the date on the unit tonight, and I will recalibrate pump #4 as well. I will also make the hole in the cap of the container a little wider so that this vacuum effect (or sucking all the air out of the container) does not re-occur.

Any other suggestions/comments/explanations would be welcomed.

I do not want to have a re-occurrence of dosing 600ml in my tank when I programmed the unit to dispense/dose only 50ml. That would make the unit worthless.

 

[Przemek_PacSun]

If your doser was working properly before tubings change and you not performed any calibrations etc after - there is no other way than problem with tubing (not properly placed rollers after changing, not proper ID/OD etc). Have you done any firmware updates or changes in settings after new tubing installation? If not and after change you see simply almost emptied bottle it can't be related with doser settings.
Doser don't know which tubing are you using - if it "dosed" more than should maybe there was "siphon effect" (if tubings are different than they should be ).
It's only one explanation of that situation. Our doser require 3/5mm Pharmed tubings (ID/OD) - using different sizes can make your liquids moving inside tubes when pumps are not working.

 

[Editour2]

As I stated above.....I switched from using a little wider Inner dimension tubing to tubing that meets your specifications for the inner dimension, (ID). The OD on the new tubing is a little bigger and that made a tighter fit with the hole drilled in each container lid/cap. Nothing else changed accept that pump #4 did not dose as programmed. All other pumps seem fine. I will check calibration and the rollers etc. I will also make the hole at the top of each container a little bigger to avoid any potential siphon effect....even though I am using check valves. Container #4 was the only one that the air was being sucked out of it so I suspect that this is part of my issue. I didn't have that issue before I changed the tubing.

 

[Przemek_PacSun]

Hello
We not suggest using other than 3/5mm(or 1/3mm) - with 1mm wall thickness. If you are using tubes with ID the same like ours but OD different - it can make doser not working properly.
If you need that kind of tubings - please send us mail, we can mail it to you by post priority(few dollars cost) and you will be sure that's proper like should be.
Please take a look for Page 55 following manual(it's about Kore 7th and kHLab - but maybe your rollers need to be replaced. If you will use to thick OD tubings it will shorten their life time.

[Editour2]

The inner dimension is 1/8 inch and 1/4 inch OD. These are dosing tubes from bulk reef supply. I just changed to this over the weekend. I have the kore 5th doser. I checked pump #4 and the rollers were on backwards so maybe that combined with the air being siphoned from the container is the issue. Where can i send sn email for your tubing and i need the pump tubing also since I found one was cracked but not being used.

Hello

Can you clarify what you mean here? Are you saying you recommend either 3mm ID 5mm OD

OR

1mm ID 3mm OD

I don't think you meant 3/5ths of a mm for the ID and 1/3rd of a mm for the OD.

 

[Przemek_PacSun]

ID - Inside Diameter
OD - Outside Diameter

both - 1/3mm or 3/5mm have 1mm tubing wall thickness.
The main difference is maximum flow - on 3/5mm nominal flow(at maximum speed) is about 60ml/min, on 1/3mm - about 13-14ml/min.
We use this precise tubings on our Kore 7th(but of course - its compatible also with Kore 5th)- 2nd channel - for dosing reagent with 0.01ml precision (its very important when doser have to calculate dosed liquids properly to measure alkalinity automatically in reef aquarium ).
If I should clarify anything please let me know!
Regards

[Editour2]

Przemek,
I am sorry to beat this topic to death here but I am still unclear.
For example:
when you say 1/3mm do you mean:
1mm is the inner dimension (ID) and 3mm is the outer dimension (OD)?

Secondly:
on pump #4 which is the pump I had the issue with....I found the rollers were reversed, (which I did by accident when I cleaned them). Also I was getting a siphoning effect in the container (only on that container). Could these issues be the cause for not dosing what was programmed?

thank you for your patience with me.
Frank

 

[Przemek_PacSun]

1. Yes, 1mm is inner diameter, OD is outer diameter.

2. As I said - it had to be issue related with tubings(now we know that with bad assembly after changing tubings).
Of course, without any doubt it could affect proper dosing and siphoning effect.

I have a 2014 first gen doser that doesn't appear to have a reset button. The unit has been in storage for a few years. I decided to re-purpose it today and attempted a firmware update. The display now says "Bootloader Ready". I reviewed what I could find online about pressing the reset button. How do I reset a unit without the button? I tried the tri-state switch from top to middle to top and that didnt have any effect.

Thanks,
Kevin

UPDATE: I can now connect via the 3 position switch from Bootloader Ready to Connected Uploading and have run the firmware updater 5 times. Each time its says it finished I reboot the doser and it shows Bootloader Ready. I'm doing this from a MAC if that makes any difference.

 

[PacSun Service]

[MENTION=37436]kpctoy[/MENTION] - Please try delete doser from your Mac, restart Mac, turn off doser power supply for 30s, next pair doser again with Mac and try to upgrade again.

Best regards
Pacific Sun Service

 

[kpctoy]

Ok, have tried again using the MAC as well as using a Windows PC. The MAC says its finished yet the doser still shows Bootloader Ready once completed. I've removed, rebooted and re-added via bluetooth 3 times. Each time is the same experience.

What am I missing here?

I did try using the app to access the device and it looked to connect. Showed firmware version 88, responded back but manually turning pumps on has no affect, The display continues to show Bootloader Ready.
