The temperatures are falling and heating will soon be unavoidable. If the heating is switched off completely in winter, it can not only damage the heating system itself, but also promote the formation of harmful mold. So not turning on the heating at all to save money is not a solution.
So the motto is: heat cleverly! But how do you set the heating optimally in order to heat as efficiently as possible? We will explain to you what the numbers and symbols on your thermostat mean and which setting you should definitely not choose.
Understanding heating thermostat: Which temperature at which number?
The thermostat is marked with various symbols and numbers. The numbers represent specific room temperatures:
Setting 1: 12°C
Setting 2: 16°C
Setting 3: 20°C
Setting 4: 24°C
Setting 5: 28°C
If you set the heating to a level of 1-5, it will automatically heat up to the corresponding temperature. If the heater stays cold even though you change the setting or hot even though you turn it down, the heater's thermostat may be defective.
What do the symbols on the thermostat mean?
In addition to the numbers, there are also various symbols on most heating thermostats. This is what they mean:
- Snowflake or star: frost protection position
- Sun: basic setting for 20 °C
- Half Moon: Night setting for 14°C
The frost protection position is not primarily intended for heating the apartment, but is intended to prevent the heating from being turned off when it is switched off, for example. B. broken by frozen pipes.
The settings of a thermostat for underfloor heating are slightly different than those for traditional radiators because underfloor heating reacts more slowly to temperature changes and emits heat more evenly. Nevertheless, there are temperature levels and symbols here that are similar to common rotary thermostats.
Reduce heating costs: The right setting for every room
In order to keep heating costs as low as possible, it is important to choose the right setting for each room. Because not every room has to be equally warm. Here is an overview:
- Basement rooms: 6 °C (frost protection mode/star is sufficient here)
- Staircase + entrance area: 12 °C (level 1)
- Bedroom + children's room (night): 16 °C (level 2)
- Kitchen + hallway: 18 °C (between levels 2 and 3)
- Living room + dining room: 20 °C (level 3/sun)
- Children's room (day) + study: 22 °C (between levels 3 and 4)
- Bathroom: 24 °C (level 4)
Tip: At night you should select the night setting (half moon) for all living rooms to save energy.

Level 5 on the controller is a real energy guzzler. You should therefore never turn the heating up so high. A room temperature of 28 °C is only intended for an indoor pool or spa area.
Tipp:To prevent the heating from (accidentally) being turned up too high, there is a small slider on most thermostats. It blocks at a certain point so that the heating cannot be turned up any further.
