The Best Room Thermostat: Our Choices
Guide: Questions you should ask yourself before buying a room thermostat
What is a room thermostat?
A room temperature controller regulates your heating so that you always have the desired, optimal room temperature in your home. Depending on the installation and system, several thermostats can also be used in different places in the house or flat.
What should I consider when buying a room temperature controller?
Before you buy a room thermostat, you should measure the wall recess available at the intended installation location.
Most room temperature controllers can be flush-mounted or surface-mounted in the same way as light switches or sockets because of their length and width of approx. 8.6 cm each.
Which cable for room thermostats?
The exact wiring diagram, which is always included with the installation instructions, should explain how to use the cable.
How much does a room thermostat cost?
If you are looking for a cheap room temperature controller, you do not necessarily have to go for an analogue model. However, the prerequisite is that your budget is more than 45 euros.
What alternatives are there to a room temperature controller?
If you need high technology and particularly value automation in the home, you need a digital and programmable room temperature controller with an interface to the smartphone and additional GPS. Heating control via Bluetooth: The Bluetooth Smart radiator thermostat can be conveniently set up and controlled via a smartphone app.
Decision: What types of room temperature controllers are there and which is the right one for you?
There are basically four types of room temperature controllers:
- digitally programmable room temperature controllers
- manually adjustable room temperature controllers
- Room temperature controllers with radio
- Room temperature controllers with WLAN
What distinguishes a digitally programmable room thermostat and what are the advantages and disadvantages?
With a digitally programmable room thermostat you have a practical LED display where you have all the important information. This is usually the current room temperature, the possible temperature deviation and temperature display as well as memories for preferred time of day or weekend temperatures.
The experience reports show that digital is basically an advantage with a room temperature controller. Digital room temperature controllers are suitable for flush-mounted and surface-mounted installation.
What distinguishes a manually adjustable room temperature controller and what are the advantages and disadvantages?
A mechanical room temperature controller does not have a display and only has a controller, as well as knobs and/or switches. You always get individual room temperature controllers here, which means that such a controller is installed in each room so that you can set the individual temperature in the rooms.
Since analogue, i.e. electromechanical, room temperature controllers are operated manually, they are easy to use and hardly require any installation work.
What distinguishes a room temperature controller with radio and what are the advantages and disadvantages?
Similar to radio thermometers, radio room temperature controllers offer a great deal of convenience. They enable comfortable heating or cooling without having to stand at the room thermostat. With radio models, an underfloor heating system can be upgraded or extended without extensive chiselling and plastering work for laying the cables.
For effective individual room control, the battery-operated radio room thermostat is connected to the radio control terminal strip in the heating circuit manifold via 868 MHz and assigned to the individual heating circuits of the floor heating system. Control is also optionally possible via the Internet.
What distinguishes a room temperature controller with WLAN and what are the advantages and disadvantages?
Many users do not want to give up the feeling of modern living, because when on the move it is convenient to switch on the heating with a room temperature controller and come home to a warm home.
Most models offer convenient control of the room temperature controller via an app that can be used with iOS or Android mobile phones. These usually have a limited range of functions.
Purchase criteria: You can compare and evaluate room temperature controllers based on these factors
In the following, we will show you which aspects you can use to decide between the many possible room temperature controllers. The criteria you can use to compare room thermostats include:
- Mounting type
- Temperature control
Before you buy a room thermostat, you should measure the wall recess at the intended installation location. The modern room thermostat is not very large. The width varies between 5 and 15 centimetres, depending on the brand. If the room thermostat is installed with a surface-mounted unit, the dimensions play an exclusively optical role.
In installations where the room thermostat disappears into the wall with the flush-mounted installation, it is particularly necessary to determine the maximum possible depth in advance and to buy the device to match.
There are various ways of classifying and assigning room temperature controllers. A distinction is made between the type of mounting, which can be either flush-mounted or surface-mounted.
|Flush-mounted||- Is integrated inconspicuously into the wall, extremely space-saving - all standard switch frames can be installed - recommended for new buildings and homes - underlines tidy|
|surface-mounted||- room thermometer is mounted in a box in front of the wall - easier to install - ideal for retrofitting - often a cheaper option|
For good programmability, it has a touchscreen LCD display and offers simple temperature control as well as a weekly programme. This way you can plan energy savings over several days and weeks. As a radiator thermostat or connected to the underfloor heating, it can be set for absence hours or holidays.
Room thermostats can usually be operated with 230 V mains voltage. However, there are also models that can be operated with a lower voltage.
The less current that flows when the room thermostat is switched, the more switching cycles the unit will survive.
The maximum switching current is always specified by the manufacturer and must never be exceeded. It is very advantageous if your room temperature controller can manage with a low ampere rating.
Room temperature controllers are available for underfloor heating, air conditioners and heaters. The adjustable temperature range is between approx. 0 and 45 °C, which means that an optimum room temperature of 21 to 23 °C can always be set.
Ideally, the temperature should be set from five and up to 35 degrees Celsius. In addition, the deviation between the set temperature and the temperature reached should be as small as possible.
Facts worth knowing about room temperature controllers
How do I install a room temperature controller?
When installing the room temperature controller, there are some technical requirements that must be observed. This includes the correct height of the room thermostat. Ideally, mount your model on a wall at a height of about 1.5 metres. Since it needs to sense the circulating air in the room for measurement, it should not be covered with curtains or furniture.
Since the connection is made directly to the power supply, regardless of the type of installation, it is recommended that this work be carried out by an experienced and certified specialist company.
It is not recommended to use the position where the room thermostat is exposed to frequently changing temperature conditions. Therefore, locations near windows are not suitable. In addition, the room temperature controller must not be placed in the immediate vicinity of radiators.
How can I connect a room thermostat?
Most models for wall mounting are square and have a size of 8.6 x 8.6 cm. When mounting, the depth is decisive, which should ideally be less than 4.6 cm. In simple models, a room thermostat is connected to the servomotor of a heater. Make sure to turn off the power beforehand so that you can work safely.
|1. Preliminary work||Switch off the power supply so that all wires remain voltage-free during connection.|
|2. Determining the installation location||The installation is normally carried out in a flush-mounted socket (ø 60 mm) at a height of approx. 1.5 m.|
|3. Connecting the thermostat||Remove the housing cover and connect to the circuit according to the enclosed wiring diagram.|
