Please help cooling setting!!!!!!!1

[ktmc]

Hi, I'm new with profilux controller .
Anybody can help tell me how to set the cooler on & off ?
Current temp 25++ , I want to on the cooler at 26c and to off at 25c.
I' m not using heater. Just 1hp compressor. Is using socket 4 .

set the desired temp. as needed (maybe you also change the hysteresis and cooling difference)

then assign the function "temp. 1 cooling" to the socket in question

everything covered in the programmer's guide

Can u show me how is it? don't understand what the manual is talking.
hysteresis ????
cooling difference ????
I just want if over 26c drop to 25c.
already waste 2 day to setting this :mad:

[Matthias]

set the temp. to 25°C and the hyseresis to 1°C, that's it
last step set the socketfunction to temp 1 cooler

I really don't know where the problem is

Hi Matthias,
Ur mean is set the nominal to 25c ?
hyseresis to 1°C then the cooling difference to 0?
This step I try so many time already...
Why Temp drop to 23c ,the socket still on ?????

[Matthias]

please post screenshots of the temp. - and socket-settings

Hi Matthias,
I get it, problem is from socket setting .
so thank you very much.

If you set nominal to 25 and hysteresis to 1, isn't the result that the cooler comes on at 25.5 and goes off at 25. If you want it to come on at 26 and go off at 25, would the hysteresis have to be changed to 2? Just asking.

Ken, you are right - because the hyseresis covers the complete invervall from switching a heater (too cold) to switching a chiller (too warm)

if someone wants to know these things in detail: read more about sensor settings in the manual ...
