ᐅ How do you control underfloor heating in a newly built home during initial occupancy?

Good day,
This topic has been discussed here several times before, but maybe someone can give me advice for my particular situation.

I moved into a new condominium in a six-family house (first occupancy) in the summer.
It’s on the upper floor facing east-southeast (bedroom, study, kitchen face east; living room faces south).
Heating system: pellet heating with a solar collector system for domestic hot water and heating support.
3 rooms plus kitchen and bathroom, about 80m2 (860 sq ft). Each room has a Salus thermostat controller.
Flooring: laminate (except hallway, bathroom, and kitchen which have tiles).
Household situation: single occupant, full-time employed (leave home around 8:30 am and return at about 5:30 pm).

I want to switch on the underfloor heating for the first time now; it has never been in operation before.
According to the heating technician, a balancing procedure was done. I am supposed to control everything using the room thermostats only.

Question:
How should I set the individual room thermostats?
For example, should I set the bedroom to 18°C (64°F) and leave it at that until summer?
And the living room? Set it to 20°C (68°F) and leave it running continuously—even if the outside temperature, even in winter, is occasionally quite warm?

I have no experience with this at all!

Are there any tips to avoid overheating? PS: The walls are practically dry—no moisture issues from the new construction. The apartment is quite “warm” since it is well insulated (KFW70 standard) and on the sunny side.

Thank you very much

As warm as you want it – but don’t expect miracles with temperature zones.
Keep in mind that there is a certain delay, so gradually increase the temperature on the thermostat and wait a day to see if you like it.

Thank you for your message.
So I will adjust step by step each day until I find the comfortable temperature.

But:
What if the outside temperature becomes much warmer or colder than it is now?
Should I leave the setting as it is or turn it down or up?

And if I am away from home for 10 hours a day, should I not turn the thermostat down? Not even a little?

Thank you very much.

I can imagine that the heating system has an outdoor temperature sensor and regulates itself. The thermostats in your rooms control the valves of the heating circuits.
In theory, once you have found the perfect setting, you shouldn’t need to make any further adjustments.

It’s hard to give a general answer – if it is a typical solid construction with a lot of thermal mass, lowering the temperature doesn’t help or can even be counterproductive because the “cold” will penetrate when you come back home.
Heating costs should be very minimal anyway.

It’s hard to give a general answer—if it’s a regular solid masonry building with a lot of thermal mass, turning the heat down doesn’t help or can even be counterproductive because the “cold” penetrates the building, especially when you come back home.

Hello.
We already have an outdoor temperature sensor, so the heating is weather-compensated.
However, I have an east-south facing apartment on the upper floor. Naturally, it is “warmer” than apartments on the north or west side.
The outdoor sensor activates quite early to make sure no one has a cold apartment.
Does this mean it doesn’t make a difference for me how I should adjust the settings?
Thanks.

You won't be able to get that sorted – it’s not systematic, but sporadic... yesterday we had 23°C (73°F) in the living room due to the sun – but it quickly evened out again.
