My heaters won't come on!

[rossbryant1956]

Continuing to add piece parts to my controller, added my heaters today. Went in and made sure my memory upload covered my heaters with the proper temps, uploaded the memory and wired up the heaters.

Now my temp is dropping, is well within the range they should be on, but not coming on. My memory file is attached:


My pde looks right but would appreciate your advice:

When the temp hit the low range temp of 78.2, the heaters came on. I would have thought they would fire as soon as the RA noticed the temp falling into the range. Thx Ross

something else that happened at almost exactly the same time is that now my PH has fallen substantially from a steady 8.4 (for weeks) to a low 7.74 and it is staying there. So please do look at my code above and see if anything I uploaded would have caused this. Thx

any advice on my pH problem? Did reloading my memory blow my calibration?

[rimai]

Yes sorry
These lines on the memory file did it:

Code: Select all

    InternalMemory.PHMax_write(840);
    InternalMemory.PHMin_write(550);

so how do I fix? Delete those two lines and reload the mem? Or set them to something else. Thx for all your help.

Did you write down the numbers when you did your calibration?

[rossbryant1956]

Of Course I Did!!

I just can't find them.

Do I use those values?

I found a post http://forum.reefangel.com/viewtopic.ph ... 251&p=2324 and set those values as stated in here to 512 and 807 and ph now says it is 8.12.

Let me know, I can recalibrate tomorrow night (or find the slip of paper)

As always, thx

Yeah, you can just replace the numbers with the ones you've written down.
