Apex Alarms

[John Ford]

So I set up a few simple alerts maybe a year ago and just recently I started to get this email once or twice a day.

 

Date: 2018-02-03 21:00:54 -0500

Status: ON

Statement: If pH > 8.50 Then ON (8.51)

 

The problem is my ph is right around 8.1 or 8.2. It’s never even close to 8.5 even if I look back at my graph it does not come close to 8.5. Is there a way to add a time delay so the ph would have to maintain greater than 8.5 for 30 seconds to limit false alarms or is there a mistake/flaw in my statement below.

 

Set OFF

If Temp > 82.0 Then ON

If Temp < 75.0 Then ON

If pH > 8.50 Then ON

 

I also want to add an alarm for my ato so if the pump runs longer than one minute but I can start a new thread or look into that more later.

 

Thanks for any suggestions.

The Defer command adds the requirement for a condition to be continuous for a period of time before the code will take effect.

 

Set OFF
If Temp > 82.0 Then ON
If Temp < 75.0 Then ON
If pH > 8.50 Then ON

Defer 005:00 Then ON

Thanks Jon!

 

Would that defer for all of the above or just the PH?

[Jon Lazar]

It'll defer all them.

 

If you only want the delay for pH, I think you would create a virtual outlet for pH, with a Defer. Then use the virtual outlet name in the list of email conditions. Disclaimer:  I'm no expert, there may be a better way to do it, and I haven't tested this code.

 

HighpH

Set OFF

If pH > 8.50 Then ON

Defer 005:00 Then ON

 

 

Email/Alarm

Set OFF
If Temp > 82.0 Then ON
If Temp < 75.0 Then ON
If HighpH ON then ON

Defer 005:00 Then ON

The virtual outlets are above my head at the moment. Haha

 

I changed the defer time to 000:30 just to shorten that parameter. So far today I have not received one apex alert.

 

Thanks Jon!
