Apex Heater Fail Safe Setting, Help Please

jsker · Jan 16, 2018

We have been living through a major cold snap there. The low temperatures have been below 60 at night for some time here in central Florida.

Last night after doing a water change and turning on my heaters to ON the heat the water. I thought that my heaters would switch off once it hit my temp setting. the heaters did not

;Jawdrop. I there a line that I can add to my settings to switch off the heaters/heater when the outlet is toggled to on or do I need to clean up my setting so this will not happen again.
Fallback OFF
Set OFF
If Tmp < 78.4 Then ON
If Tmp > 78.6 Then OFF
If FeedC 002 Then OFF
If FeedD 002 Then OFF

If there is i personally don't know of it.. on is on to me. Auto allows the apex to use its logic. What are the heaters set to? Or are they just an element

They are Fennix heaters.

I alway was under the impression that once a temp was reached the outlet would shut down for heaters.

uhhh.. i don't know why it didn't shut off when it hit the target temp. Mine always shuts off once it hits the off temp target and only turns back on once it falls below on temp target.

Is your heater plugged into outlet 4 on your eb8?

Under auto or on?
Same logic the other way the original poster, if it was off, you would then want it to kick on when it got too cold. If i was doing a water change and the heater was exposed if it kicked back on that would be very bad. So pretty sure on / off ignor the coding for that reason.

8 on EB8, the light just click on in my head. So this would be the issue since 4 and 8 are static? The other everyday one is plugged into 7

Yes removevthem from four or eight
Your code looks ok
How many heaters do you have

XNavyDiver · Jan 16, 2018

I followed Terrance's guidance when I originally set it up, which said outlet 4 for the heater. Has never failed to turn the outlet on and off when the temp parameters are reached.

Does anyone see the original question...he has it on ON not auto.

I would flip your heater switch back to Auto. If it is set to ON that will override any programming that you have set.

On a side note, aren't we Central Floridians spoiled?

2 right now, one is for backup for the cold nights. I enjoy the cold and the heat does not kick on until the house gets down to 60 at night and I need a back up heater since I have been using a 300w.

It works fine on Auto, but not when It is switched on and left on.

LOL that is so true.

Because on overrides programming...

Thank you,

Kind the whole bases of my question. Even though it is on and the EB's are controlled, then why can there not be a code line that overrides the physical on for heaters. That is one of the reason most buy a controller is for that fail safe of not burning up the system with a failed heater. And one other thoughts is if physical static outlet fails the apex would shut down the EB entirely or the outlet.

ontop27 · Jan 16, 2018

There is...its called auto

ontop27 · Jan 16, 2018

What you are asking for would make off or on useless because it would still follow the programming rather than be 100 percent off or 100 percent on

azreeftank · Jan 16, 2018

Could you please explain in more detail why a heater can’t be on certain outlets, like 4&8? I always figured all outlets are fair game as long as you Program for what you need it to do. I have an Eb4 and Eb8 on mine. Thanks

If you toggle the heaters to ON they will remain on, until the temperature that is set by the heater turns the heater off. So, it sounds like the temperature on your heaters is set too high. Now, if you set the heaters to AUTO they will turn ON and OFF according to your programming.

Personally, I would change your programming to:

Fallback OFF
Set OFF
If Tmp < 78.4 Then ON
If FeedC 001 Then OFF
If FeedD 001 Then OFF
Defer 001:00 Then ON
Defer 001:00 Then OFF

Outlet TEMP_TOO_HIGH:
Fallback OFF
Set OFF
If Tmp > 78.9 Then ON /* or whatever value you want */

EMAILALM_15:
If Outlet TEMP_TOO_HIGH ON then ON
