Apex Code Review - Adding OSC command to my ATO code

Drauka99 · Jun 15, 2016

I have decided to add kalk to my ato reservoir. Looking at the output on Apex my ATO is running about 6 times a day for 10 minutes each time. So ~50ml a minute at 60 minutes is 3000ml a day. I am being generous at 3000ml, its likely more along the lines of 2500ml

My current code is

Fallback OFF
Set OFF
If SumpLo CLOSED Then ON
Defer 005:00 Then ON
If SumpLo OPEN Then OFF
If SumpHi OPEN Then OFF
If AtoLow OPEN Then OFF
If Sw2 CLOSED Then OFF

I was thinking of adding an oscillating command to make the pump run shorter times throughout the entire 24 hours. Would I just add the command like this

Fallback OFF
Set OFF
If SumpLo CLOSED Then ON
Defer 005:00 Then ON
OSC 000:00/002:30/057:30 Then ON
If pH > 8.40 Then OFF
If SumpLo OPEN Then OFF
If SumpHi OPEN Then OFF
If AtoLow OPEN Then OFF
If Sw2 CLOSED Then OFF

I really want to keep the defer command in there but can drop it if you think that's going to be an issue. I am also fine with small amounts of kalkwasser being added through the day, my PH runs a bit on the low side even during the middle of the day.

Disregard SW2 code at the end, that is a tank service switch i setup to kill several outlets during sump cleanings and big water changes.

The way I see the Defer statement is that IF SumpLo is CLOSED for 5 minutes continuously then set the outlet register to ON; This does not definitively turn on the outlet. No damage is done IMO. The OSC might pump enough water to change the SumpLo to OPEN within 5 minutes and the Defer statement might be ignored sometimes.

The way I understand it the defer statement would have kept the pump off for 5 minutes when its state was triggered to on, since it was only triggered on for 2 minutes 30 seconds it would have never met the 5 minute requirement.

I had posted this same question on the Neptune Community Forum and got a response with the code format I have been using for the last few days

Fallback OFF
Set OFF
OSC 000:00/002:00/028:00 Then ON
If SumpLo OPEN Then OFF
If SumpHi OPEN Then OFF
If AtoLow OPEN Then OFF
If Sw2 CLOSED Then OFF
If pH > 8.40 Then OFF

quite simple the ATO pump can run for 2 minutes every 30 minutes (I changed that to make the ph swings even smaller), unless one of the other switches tells it to stay off. Quite an simple solution.
