Room thermostat

The correct setting of the room temperature is an important aspect for well-being in our apartment or house. If you are not sure which room temperature controller you should choose, here are a few tips and hints.

Are you also one of those people who react sensitively to temperature changes, who quickly freeze or sweat? Setting an incorrect temperature can cause discomfort and even health problems. With a room temperature controller, you are able to keep the temperature in your home constant. You don't have to worry about rooms that are too warm or too cold. In the office, warmer room temperatures are not only beneficial for employees, but also have a positive effect on productivity. If the temperature is too cold, employees get sick more often and cannot concentrate as well. It is all the more important that the temperature in the office is right. With a room temperature controller, you can easily regulate the temperature yourself and ensure a pleasant working atmosphere.

Tips for searching

This catalog is located in the main category 'Electrical Material'. Here you will find analogue room temperature controllers, programmable devices, room temperature inserts and actuators. If you are looking for KNX room temperature controllers for your building automation, please use our search or visit the main category 'Smart Home'.

There are many different types of room temperature controllers on the market. We will help you to find a device that is suitable for your needs.

What types of room temperature controllers are there?

There are different types of room temperature controllers. These differ in structure, mode of operation, type of operation and price. The simplest room temperature controllers are the analogue devices. These are easy to use and inexpensive to purchase. The temperature is usually regulated steplessly by means of a rotary disc. Some models also have an ON/OFF switch. The installation is usually flush-mounted. There are also models that can be surface-mounted. With digital controllers, enter the setpoints directly. There is no dial here. If these are programmable, set the room temperature for different days and times in advance. Such a device then adheres to the specified configuration over the programmed period of time. So-called 'smart' room temperature controllers offer many individual options for setting the temperature. These can be freely programmed and provide interfaces to building automation systems. It is usually operated using buttons on the device or a touch screen.

Where should the room temperature controller be installed?

A few things should be considered so that a room temperature controller can measure and regulate the temperature precisely. Basically, such a device determines a difference between the current room temperature and a target temperature. This can be done mechanically or via a sensor. Corresponding signals are then passed on to the heating, which lead to an increase or decrease in the room temperature. Attach the controls so that an accurate measurement can be made. Incorrect measurements mean that the heating is activated too early or too late and the room temperature does not match the desired temperature.

Which circumstances could lead to incorrect measurements?

The room air cannot circulate around the room temperature controller. Heat builds up in niches. The air exchange is also low behind cupboards or curtains. Here the controller may measure too high a temperature or react too slowly to changes. A measurement too close to the radiator is also critical. It gets warm too quickly here and the controller switches the heating off again. As a result, the desired temperature is not reached in the room. In contrast, installing it in areas with a lot of drafts or near a window that is often open will result in readings being too low. Here it can happen that the room gets too warm or a lot of heating energy is wasted. The controller does not switch off the heating correctly.

Assembly

Flush-mounted room temperature controllers can be installed in a normal switch box or a cavity wall box. Surface-mounted devices are attached directly to the wall. In any case, please follow the manufacturer's instructions exactly when wiring. This is the only way to ensure trouble-free functionality.

Please pay attention to the following during installation:

a mounting at about 1.60m above the floor
good air circulation without heat build-up or draughts
a mounting location without direct sunlight
attachment to an internal wall

Which temperatures are ideal for well-being?

The ideal living room temperature depends on personal preferences and the time of day. As a rule, however, the temperature in living rooms should not be below 16 degrees Celsius, otherwise the risk of catching a cold or other health problems increases. During the day temperatures can be a bit higher, while the bedrooms are usually cooler. In Germany, the following values are considered optimal:

Living room: 20°C to 22°C
Children's room: 20°C to 22°C (18°C at night)
Bedroom: 16°C to 18°C
Bath: 20°C to 23°C (depending on usage and time of day)
Kitchen: 19°C

TIP:

Each additional degree of room temperature increases the heating costs. Use the possibilities of modern heating systems and lower the room temperature in unused rooms by around 5°C during this time.

To save energy, you can schedule heating breaks, for example. Adjust the devices so that the room temperature is lower when you are not at home. If you are away for a few days, reduce the temperature to 15°C or slightly lower. Based on this, you will reach the feel-good temperature after your return within 1 to 2 hours.

Do room temperature controllers require a power connection?

In order to work correctly, a room temperature controller needs a power supply. Unless it is a device with radio technology, you need a cable from the heating circuit distributor to the controller. This serves to supply the controller with power and to connect an actuator. You therefore need a cable with at least four conductors and a corresponding cross-section, of which the yellow-green protective conductor is used exclusively for protective earthing. When buying, make sure that you have a 24V or 230V system.

How do I set the exact temperature with analogue room temperature controllers?

Some analogue room temperature controllers with a rotary disk do not show the room temperature in °C, but rather a scale, often from 1 to 6. It can be a bit difficult to find the optimal temperature here. However, there is a reason for this. The manufacturers do not label the heating controllers with degrees, since other factors influence the room temperature. Deviations arise, for example, from accumulated heat or draughts. If this is the case, the temperature on the controller does not match the temperature in the room and differences arise. The scale roughly corresponds to the following temperatures:

* (asterisk - if present) corresponds to approx. 5°C and is designed as frost protection
Level 1 corresponds to about 12°C
Level 2 corresponds to around 16°C
Level 3 corresponds to around 20°C
Level 4 corresponds to around 24°C
Level 5 corresponds to around 28°C

If it is colder on the room temperature controller than in the rest of the room due to drafts, the set level 3 may already correspond to room temperature level 4. In the opposite case, the room temperature may only be 16°C, although for the controller it is in a niche Accumulated heat has already reached 20°C. The heating is switched off too early. In these circumstances you have to try something to find the optimal setting position.

With a modern heating system, you can regulate the temperature in your immediate vicinity individually. In the eibabo® technology store you will find numerous room temperature controllers that you can integrate into your heating system depending on the requirements or equipment. When buying, pay attention to quality. Here in the shop you can get top devices from manufacturers such as Busch Jaeger, Eberle, Gira, Jung, Theben, Devi and dozens more.
