Why?

Estimate based on the ISO 7730 comfort model.

Read the room you are in, away from a radiator, a window and direct sun. Humidity matters as much as temperature: at 21 °C, going from 35 % to 70 % clearly changes how it feels. The two fields are independent — a thermo-hygrometer shows both side by side.

How you experience temperature
I run cold
I run hot
Why?

"Run hot" = easily bothered by heat — the exact antonym of "run cold", which feels the cold quickly. With nothing selected, the calculation runs in neutral mode. Each pill is a toggle: click the active pill again to go back to neutral.

Kind of space
m²
Why?
The effect is concentrated in small homes: the envelope-to-volume ratio scales as 1/√A. Doubling from 25 to 50 m² shifts the setting by 0.2 °C; from 300 to 600 m², by only 0.1 °C. And it shows up more in a house than in a flat, which exposes about 15 % of its surfaces whatever its size.

Why?

If you have an outdoor thermometer or a personal weather station, your reading beats the forecast: it comes from your own place. Leave blank to use the weather service. Measure in the shade, sheltered from wind and away from walls — a thermometer in direct sun can read 10 °C too high.
