Gas pedal and parking brake of the heater: Explanation correct?

Night setback can be helpful under certain conditions, but most of the time it is not sensible. By runtime I mean that the heating heats for as long as possible. Optimal are single-digit start numbers per day. The concept of modern surface heating systems is to deliver low temperatures over a large surface area.

that's too easy again...

Well, with you, the hydraulics through the mixer and storage are not particularly good. That's why it’s more complicated there.

Actually, it is quite simple as long as the heating engineer hasn't messed up the hydraulics.

-Supply temperature as low as possible
-Running time as long as possible
-Flow rate only balanced with the thermostatic radiator valves
-Adjust temperature via heating curve

After that, in the best case, you never have to touch the heating again

Can the running time be adjusted somehow or is it simply influenced by the other parameters?

For me, currently for heating a
min. target supply temperature of 15 degrees C
max. target supply temperature of 90 degrees C
was set.

Should I lower the 90 degrees C as well or does the device need this possible high value for some cleaning functions?

The runtime results from the maximum flow temperature and the heating curve.

Simply put, the heating curve of the heating system indicates which flow temperature you need at which outside temperature to achieve a certain temperature.

So I have understood the heating curve. Do you also know if the maximum target flow temperature can be turned down? Currently it is set to 90 °C for me. I just thought that the 90°C only needs to be reached for cleaning processes. Because I never need 90°C hot water for heating.

Does anyone know why I only get a maximum of 1l flow in the sight glasses? They are fully opened
