Apex programming question

[kaspm]

I'm trying to program my brs dosing pump. My current code is this:

Fallback OFF
OSC 000:00/001:00/079:00 Then ON

I want it to run for 1 minute every 80 minutes. However when I plugged it in, it never turned off.

Also I have a 120g tank and my pump is 2ml/min if I do the recommended .1ml/gal I should dose 12ml per day, does this seem correct?

Thanks

Try adding in:

Set OFF

before the OSC command

Also, which outlets are you using. Some are designed for small loads, others not.

I use mine like as a light setting what time on and what time off no programming ? Hope this help sure is a lot easier.

I tried the link and that's the code I have but it still doesn't seem to come on. I have it plugged in to outlet 6

Dosing pumps are a low wattage device and if you are using a EB8 energy bar (Not the New EB832) then the BRS dose pumps will only work on outlets #4 and #8

Along with it wanting to be on #4 or #8, remember that the OSC command "resets" itself at midnight every day. Your code is correct for the pump to run for 1 minute on, 79 minutes off - but that 80 minute interval will start at midnight. So depending on when you plugged in and programmed the outlet, you might have to wait up to 80 minutes to see the program work.

Also... make sure your outlet is set to "auto".

Also, the BRS dosers are 1.1mL/min. Have you tried this calculator?

Update it is working in outlet 6. Also the pump I got is coming in at 2ml/min based off of how much it doses in 10 mins.

Update it is working in outlet 6. ...

I'd strongly advise you to move it to either #4 or #8. Strongly.

Just because it's working now doesn't mean it will continue to work. Low Wattage devices (say less than 5W) on any of the triac-controlled outlets (1-3, 5-7) will not *reliably* turn on or off. It may turn on/off just fine 50 times in a row, but on the 51st time it might not turn off. You really don't want to risk that with a doser. A powerhead... no big deal. But not a doser.
