ᐅ Setting the underfloor heating – desired temperature preference

Hello dear forum,
I have the following problem in my new build.
My temperature sensor is turned all the way down.
However, I can’t tolerate the temperature in the living/dining room.
It is 25 degrees Celsius (77°F) here. How can that be?
I have already lowered the desired temperature setting on my boiler, but it doesn’t help.
I have one heating circuit for the kitchen, one for the dining room, and two for the living room. All open to one room. Is it correct or possible that all heating circuits are controlled by a single temperature sensor, or did they forget to install some?
Thank you very much!

Knallkörper26 Feb 2018 19:31Our heating system is very simple. There are three outdoor temperatures, each assigned a corresponding flow temperature.
For me, it looks like this:
20°C (68°F) outside: 22°C (72°F) flow temperature
5°C (41°F) outside: 30°C (86°F) flow temperature
-10°C (14°F) outside: 36°C (97°F) flow temperature
These three points essentially define a linear curve with a kink.
You can also set certain limits: my heating system turns off at outdoor temperatures above 15°C (59°F). So the flow temperatures above that are only theoretical. Additionally, a minimum and maximum flow temperature can be set.
It should work like this for almost any heating system.

There are two rotary knobs and a menu display. The technician said the menu display is for viewing only, no adjustments. That’s his responsibility. Rotary knob A controls the maximum flow temperature, ranging from very low to very high. Rotary knob B is marked with a faucet symbol and controls how hot the domestic hot water should be. We have it set to 50°C (122°F). He suggested I turn it down to zero from Easter until October, as the solar system should handle hot water alone during that period. The heating system then won’t produce any hot water at all.
That’s as much as I’m allowed to adjust, he said. Because customers often mess things up and then call on Sundays complaining the house is cold, always saying they haven’t changed anything. Apparently, teachers are especially like that, he added. [emoji4]

There are many factors. We have a supply temperature of about 30/32 degrees Celsius (86/90 degrees Fahrenheit) at -12 degrees Celsius (10 degrees Fahrenheit).
Limits for a heat pump include, among others, the upper heating limit and the bivalence point at the lower end. The heating curve must be adjusted for each house and system, depending on the heating load, orientation, and personal comfort temperature.
