Flow temperature 30°, return temperature 28° (return too warm, you could have the flow temperature turned down)
No. Unfortunately, the conclusion is physically not possible. Example: Maybe at that time only the valve for the guest bathroom is open.
Another example: The heating has been off for days, the house is cold. But now, after the annual vacation, I want to heat again. Meanwhile, the sun warms the floor to 20 degrees. Flow temperature is 10 degrees, return temperature is 12 degrees. Still, I do not have enough heating power by far.
I have now assumed my control system and have not shared all the details.
So, according to the instructions, you would proceed approximately as follows:
Set the flow curve.
Set the return curve.
The return curve and temperature limit must of course be lower than the flow.
In certain cases, the return temperature would then throttle the flow.

There are two rotary knobs and a menu screen. Menu screen, said the technician, just look, don’t change anything. That’s his territory.
Hmm, the two knobs only define the limit values, meaning they are just emergency brakes or full throttle.
Behind the knob in the middle, however, hides the entire control of the system. But if you are satisfied with the technician’s setting, then that’s fine.
I’m not allowed to adjust more, he says. Because customers always mess everything up and then call on Sundays because the place is cold and always say, no, we didn’t do anything. Especially teachers are like that, he says.
He says that...
In certain cases the return temperature would then throttle the flow temperature.
That’s already done by the outdoor temperature control.
