Firmware update: GHL Doser 2 level control!

[Matthias Gross]

Hi

I am happy to announce the new firmware 1.09 BETA and the new GHL Control Center 1.0.7.0!
It took longer than we planned, but we wanted to achieve the best features possible.

The GHL Doser 2 has now full level control:
- automatic water change (AWC)
- auto top off (ATO) in 3 modes: 1 sensor, 2 sensors (as backup), min - max control
- mixed mode AWC + ATO

ATO and AWC timer controlled

supports up to 4 level sensors and 3 independent level control circuits

Doser firmware 1.09 has BETA status for a few days, we will change it to release state after a few days.

The level settings are added right now to myGHL.

Does the control center d/l include the firmware update?

 

[Matthias Gross]

no, GCC includes only release versions

the 1.09 BETA is an extra download in our download section

Is there any news on the magnetic stirrers?

And also power bar hook up as you cant do a water change effectively through 45ml/min. For water change we need to be able to hook up external pumps. Although this becomes expensive when you factor in the power bar so maybe some DC 24v pumps that could plug into the sockets on the back of the doser currently assumed for the stirrers?

Thanks in advance.

Overwhelmed(in a good way) by the amount detail and functionality of this update.

Nice work!

Thank you so much! This update was really hard and took a lot of time. But the next update is already in the pipeline!

Where can I find any info on how to use the new level control features? Specifically AWC.

I setup AWC using the Doser 2 just as I would dosing anything else. I'd like to know what specifically should be done for AWC.

From what I remember; in GCC - there should be a tab for level sensors. There you can select level sensor 1 and 2; and their function - like level 1 as ATO/Max and 2 as Min.


It should be in the manual; I learned how to set it up from there.

Here's how AWC is done on the GHL Doser 2:

1. Go to "œDose Overview" and select the first doser pump you wish to use for AWC.

2. Change this pump setting to "œLevel Control", set Index to "œ1", and Function to "œFill Water".

3. Go to the next doser pump you wish to use and change this pump setting to "œLevel Control", set Index to "œ1", and Function to "œDrain Water".

4.Go to "œTimer" settings and select "œEvent Start" in the switchmode box.

5. Select the days of the week you want this timer to run.

6.Click "œNew" and set the time you want this timer to begin.

7. Go to "œLevel" settings.

8. Select Control circuit 1 and set Operation mode to "œWater Change". Set the maximum-on time also.

9. In the same window, select "œ1" for Activated through timer.

10.Select the level sensors you want controlling this function. If you are using sensor 1 and 2, select 1 and 2 as shown in the photo.

11.Click "œOK" and save your settings.

There's a new manual for the GHL Doser 2 coming soon.

Can you please explain what the settings do exactly? I'd specifically like to know how the timer and sensors work in this scenario. Do we have to use the sensors?

What if I just want to change out 1.5 gallons per day?

 

[Vinny@GHLUSA]

With those settings the AWC will work as follows:

1. The doser drain pump turns on and runs until it drains enough water to meet the lower level sensor in the sump.
2. The doser fill pump then fills the sump with new SW until it hits the top level sensor.

The timer settings allow you to pick what days you want to run the AWC and what time to start it. You can also set the maximum-on time as a failsafe.

Sensors are required to operate the Doser 2's AWC feature as it was intended. It is possible to run them solely on the timer functions, but that is at your own risk.

Changing out 1.5 gal per day would mean running the motors for over 2 hours. As long as it stays off for 2 hours to rest, it is okay. Keep in mind that running the pump for this long will lessen the life of the motor given the extended run-time.
