Delayed Chiller/Fan startup

I've noticed a significant amount of toggling as the temp bounces between the on value and below on value for my fans. Is there a way to put a delay on the standardfan option so it comes on 15 mins later or so? I was thinking about using the MH function to try and substitute but couldn't really make sense of it.
Thanks in advance!

Can you post the function you are using?
You have to make sure to leave a certain difference for histerisys.

I'm just using code from the Tutorial:
http://www.reefangel.com/Support.Relay- ... rdFan.ashx
Code: Select all
ReefAngel.StandardFan(Chiller,775,783); // Setup Chiller to turn on at 78.3F and off at 77.5F
I've noticed the fan toggles on and off (as a result of the temp probe reporting between 78.3 (on) and 78.2 (off). I assume the way it should work is once the temp reaches 78.3 the fans should turn on and stay on until the temp reaches 77.5?

Yes, that's how it should work.
Maybe you have something else in your code. Can you post it?

else

}
}
It's been cooler lately so the fans haven't kicked in. When I get off work I'll setup borderline temps with the ambient reading to make sure it's still happening.
As always, thanks for the help!

Working as intended here.
This line is redundant though.
The function ShowInterface() calls it in every loop.
