noob fan problem

createdlight · 07/04/2011, 07:43 AM

Hi all , I'm a noob with the apex system, but trying to set it up after having it for months now with only temp and ph probe...LOL
Well anyhow trying to setup up a fan, house fan (sits by top of tank) i have it plugged into energybar #8 slot which is a relay port i guess? and i programed for the 8 spot (FALLBACK:ON)(TEMP PROBE: TEMP)(ON TEMP:81.0)(OFF TEMP: 78.0) well temp got to 81.8 in tank as far as the display read, and fan did not come on. i did turn it on through the manual set up (auto,on,off) and it works, so i know i have it plugged in the right spot on the energybar.
anyone any idea's?

thanks gary

this is what i have it works for me

Fallback ON
If Temp > 78.1 Then ON
If Temp < 77.7 Then OFF
Defer 001:30 Then ON
Defer 001:30 Then OFF

I really don't understand this defer statement?
what ever it is it seems to fight itself
at 001:30 then on and 001:30 then off ....on and off at the same time???

RussM · 07/04/2011, 09:56 AM

No, they don't fight one another; in fact they work totally independently. One delays the outlet from changing from ON->OFF, the other from OFF->ON. You can have defer in one "direction", or both "directions". Or none at all, of course.

Did it work for you?

You can just paste in the one i posted and see if that works.
defer is on page 58 on The Unofficial New User Guide

Pulling hair out!
Ok here's what i redid....i changed mod for #8 to advanced under modify outlet, this let me program outlet to (Fallback on)if temp > then 81.5 then on
...if temp < 78.5 then off. Fan did come on for awhile, but shut off way before set point, it seemed to shut off at 80.0 and not the <78.5 that i programed. And i did not see any option for defer at all?
Am i doing this programing right?

Thanks gary

aquamanic · 07/04/2011, 01:08 PM

Did you have a Set OFF in that program? For example

Fallback ON
Set OFF
If Temp > 81.5 Then ON
If Temp < 78.5 Then OFF

Follow the above example...the Set OFF will take precedence as soon as the temp drops to 81.5. It will never get to the 78.5. Since in the above example, you have both ON and OFF conditions specified, simply remove the 'set OFF' and you would be good.

Sorry no i have no options for "set", in setup/outlet setup/program outlet,
only options are fallback,if temp >xx then on, if temp < then xx then on. Those are the only menu options i see, to set this up?

In advanced mode, you need to type on the commands.

Thanks man! i'm blind as a bat! i never saw the options at the top of the screen, when using cursor at the beginning of each line!
ok so as you guys recommend, here's the program

FALLBACK ON
SET OFF
IF TEMP > 81.5 THEN ON
IF TEMP < 78.5 THEN OFF

Cool so this should work?

K another question on my heaters... i have two 250 watts

do i need the exact same program lines? except FALLBACK OFF AND THE SET TO OFF TOO ??

RussM · 07/04/2011, 02:33 PM

That code won't work as expected. The problem is that the Set OFF will be used when ever the temp is <= 81.5; the If Temp < 78.5 will never be used.

Use this:

FALLBACK ON
SET OFF
IF TEMP > 81.5 THEN ON

-OR this-

FALLBACK ON
IF TEMP > 81.5 THEN ON
IF TEMP < 78.5 THEN OFF

I'd narrow the temp range a little bit though... maybe 78.5 - 80.5.

I probably didn't word my post #9 all that well. I was trying to figure out why your program wasn't behaving as you expect and I was asking IF you had a SET statement, not that you should add one. In any case, follow post #9 or Russ's #13 and you'll be good.

Rule of thumb is, if you're going to have both the ON and the OFF conditions specified, then do not use a SET statement - it will mess you up. Otherwise, you always want to use SET so you get to a good consistent starting point in your outlet program.

david00061 · 07/04/2011, 03:33 PM

with heaters and fans the defer opion is a good idea. It helps take all the on off away
