I have been assigned to do an experiment where temperature control is necessary. The profilux 3 and GHL doser 2 is available. I've installed the program on my computer, but I just can't seem to figure out how to make it work.
I have the two temperature sensors (1 and 2, plugged into profilux 3) and an aquarium heater plugged into the socket (and I have put in the right socket with temperature and heating on the system switch channel option.

I have a container with water in it, with a set temperature, but I want it higher. How do you go about that? (I've tried setting the temperature I want under the Probe/sensors menu, then taking temperature 2 in this case and inputting the temperature I want under nominal value both on the computer and on the profilux 3. On the display it says the temperature it is in the water, then on and a circle)

I don't have any clue about this stuff, so help would greatly be appreciated.
