Apex Controller Question

[Davisc1293]

I installed a fan to come on at 79.6 and turn off at 79.6... the first day it worked great with the graph showing a very consistent swing from 79.6 to 79.7 back down to 79.6 and so on as the fan cycled on and off... it is still working great but today after messing around with some other things it is now going from 79.7 the fans come on and cool it to 79.5 and then going back to 79.7 I'm by no means complaining about this .2 swing. Just wondering if I am missing something because it was working "better" if you can even call it that.

Temperature isn’t always updated in realtime, so parameters can sometimes drop or increase by more than +/-0.1.

You are better off with the .2 temp swing- on/off constantly will burn your fan out.

I was more worried about the controller itself I used a very inexpensive PC blower fan like you'd see inside a laptop.... actually very effective for a tiny little fan... but I'm not gonna worry about it like I said I wasn't worried about the next to nothing swing was more curious what I could have changed lol

Well. If it bothers you then just undo what you’ve changed to get it back to square 1 but yeah- if you’re not concerned with the continual on/off then you can’t do much better than a .2 swing similar to the wear on your fan, the switched outlet doesn’t have an infinite amount of on/offs either so you may want to consider that.

That is to close of a swing between on and off for any sensor and controller. The margin of error of any sensor isn’t that close. I would at least change it to 79.6 and 79.3, and that is close. When I used my to Apex to control my fan I turned it on at 78 and off at 77 degrees.

At on and off at 79.6, it will never know to turn on and off.

While im sure the tolerance are not nearly that tight but it does seem to be doing a great job
