Dosing Pumps
The controller is capable of controlling 8 DC Dosing Pumps allowing you to fertilize your plants or whatever you can come up
with. Each pump has its own set of schedules. The controller tracks how many doses are remaining in each reservoir, when a
reservoir is empty the dosing pump won’t run, press the Refill Bottle button when you fill it up. You can also adjust the
controller to run the same speed as your pump. The controller is setup for 12v DC pumps but can be used with 6v pumps
using a DC regulator to drop the voltage.
Changing Dose Amount and Manual Dosing
From the Home screen press: Settings > Dosing, and
you get the screen on the left. Here you can adjust
how large the dose is in milliliters for each pump and
tell the controller you refilled the reservoir. You can
also manually dose each pump by pressing the
Manual Dose, for that particular pump.
The maximum dose amount for each pump is 250ml,
each reservoir can hold a maximum of 250 doses and
the maximum reservoir size is 2550ml. All this is
taken into account when you change your settings.
For example if you have the bottle capacity set to
2000ml but you wanted to dose 5ml, that would be
over the maximum amount of doses allowed per reservoir so to set 5ml you would have to adjust reservoir size to 1270ml or
less.
Press NEXT, bottom right, to view pumps 5 – 8.
Calibrating Dosing Pumps and Reservoir Capacity
From the Home screen press: Settings > Hardware >
Dosing Pumps, and you get the screen to the left,
DOSING PUMP SETTINGS, where you can adjust the
speed and reservoir capacity for each dosing pump.
First you can adjust the Pump Rate for each dosing
pump. This is where you calibrate each pump so they
dose accurate. Follow these steps to calibrate your
pumps. It’s recommended to use a small measuring
cup, one around 10ml will work just fine.
1.
Stick one hose in a container of water, the other hose place it in or hold over the measuring cup
2.
On the Dose Settings screen set the Dose Amount for each pump to 10ml or the size of your measuring cup.
3.
On the screen to the left press the Manual Dose, to see how much is pumps. If the dose is more or less than 10ml adjust
the Pump Rate on the screen above. Repeat until you get a 10ml dose.
4.
You can now set the dose amount to the amount of fertilizer you wish to dose.
