Just wondering if you tried setting the max
to 255 or higher to stop the flashing?

I believe the flashing is because the process
variable is outside of min/max settings.

ok.
I try to do this.
only the maximum value?

I noted that it flash also with negative values..

example..we are in stable temp 85°C. I’ll see:

85…. 170….85……-27…..85….
in random way… the value 85 is surely more present then the flash values that appear and disappear very very fast!

here a video of previous unit that show you the problem

Im thinking the ‘A value is being interpreted
as a value outside your min/max. It will probably
lead you to using a digital gauge.

Ian has also added a number of functions that
might be able to average the occasional bogus
reading away. Should be listed in his wiki links
above.

wow!
very interesting!

but how to use this?
where i have to write the equations?
and specially which I have to use?

I suppose this:
EWMAF(weight:value)
Exponentially weighted moving average filter – filter noisy signals here. ‘weight’ should be between 0(more smoothing) and 1(less smoothing)

Equation: EWMAF(0.001:((A*256)+B))
Equation: EWMAF(1.0:A)
Equation: EWMAF(0.1:Val{Tilt(z)})

sorry for my stupid questions..
but where I have to write this equations?
and I have to write all the equations yous wrote?

PS: I tried to change the scales..the minimum and the maximum..the problem remain..the shown error values is lower, it stay in the the range, but it flash in any case.

There are no stupid questions.

No you don’t have to enter all
the examples. You need to edit
the equation of your custom pid
and put your current equation into
the value portion of the EWMAF
function. My equations were just
examples of how to use the function
and its syntax.

Ok my equation is AC-40

Can you write me what I have to put considering my equation?

Equation: EWMAF(0.1:AC-40)

You can change the 0.1 value as needed to smooth.

nothing…
I gone with the value up to 1.
tried
0,1
0,5
1
the problem stays.
smoother but it stays
