How to program an alert based on temp differences?

[ca1ore]

Cannot work out how to do this, or if it is even possible with the current programming options in apex. I have a temperature probe in my sump and another in the display. I want to setup a virtual outlet to alert/be notified if the difference between the two readings exceeds a certain value. Something like ...

SET OFF
FALLBACK OFF
If Temp_1 < Temp_2 BY MORE THAN 1.5 Then ON
If Temp_1 > TEMP_2 BY MORE THAN 1.5 Then ON
Defer 005:00 Then ON

Bolded text is syntax not supported by apex. Anyone have a clever way to do this?

Go to your task page in fusion, go to probe alarms, click on temp, click which temp probe as you have two, fill in the blank with minimum and maximum temp, click next, then after it loads click ok. Repeat for your second probe.

Unfortunately the apex programming language is extremely limited and I don’t believe there is any way to do what you want. It won’t even let you compare your two temp probes... you can’t say If Temp_1 < Temp_2... you can only compare a temp probe to a specific number.

Ok, that's what I figured. Thx for confirming.

I’ve done what your asking and I posted the steps above, or am I missing something?

What you posted is not what he’s asking. He has two temp sensors and he wants the apex to alert if one sensor is 1.5 degrees higher or lower than the other sensor. Not if the sensors are higher or lower than a specific temperature.

Ah ok sorry

Yeah to a large degree it can be said that the Apex doesn't do math; no way to test for sums or differences.

OK that is what I mostly thought - couldn’t hurt to get another opinion or two just in case I’d missed something.
