Basics of sauna control

The sauna control unit (also known as the sauna control unit) is a crucial element that significantly influences the functionality and safety of a sauna. It is a system that regulates various aspects such as temperature, humidity and time control to ensure an optimal sauna experience.

How does a sauna control unit work?

A sauna control unit is the central element for regulating the conditions in a sauna. It allows you to set and control the temperature, humidity and other functions. Modern control units have digital displays and are often equipped with sensors that enable precise measurements. This ensures a constant and pleasant sauna environment and increases safety by automatically switching off the sauna when a maximum temperature is reached.

Different models and their power capacities

The power capacity of a sauna control unit varies depending on the model and is tailored to different sauna sizes and types. Models for smaller saunas often have outputs of up to 9 kW, while larger saunas require control units with capacities of 10.5 kW or more. These differences in power capacity affect how effectively the control unit can regulate the temperature and other conditions in the sauna. Making the right choice is crucial for an optimal sauna experience and energy-efficient operation.

Choosing the right sauna control unit: What you should consider

Choosing the right sauna control unit is crucial for an optimal sauna experience. There are several factors that should be considered when making your choice, including the specific requirements of your sauna, the desired functions and compatibility with your sauna heater.

Temperature control and humidity

Temperature control and humidity control in a sauna are critical to the sauna experience and user safety. Modern sauna control units offer precise temperature control, allowing the sauna temperature to be set exactly and kept constant. This is important to ensure a comfortable and safe sauna climate.

Humidity control also plays an important role, especially in steam or bio saunas. Appropriate humidity levels help to create a relaxing and therapeutic environment and can be customised according to the user's needs. The combination of these two elements allows for a personalised sauna experience.

Compatibility with different sauna heaters

The compatibility of a sauna control unit with different sauna heaters is a crucial factor for efficient and effective sauna use. Traditional sauna heaters require control units that are specifically designed to regulate high temperatures. Bio sauna heaters and combination sauna heaters, on the other hand, require controls that can handle both higher temperatures and the production of steam.

It is important to choose a sauna control unit that is not only compatible with the type of heater, but also supports the specific functions and requirements of the heater. A correctly selected control unit ensures an optimal sauna experience and a long service life for the heater.

Examples of the compatibility of sauna control units with different sauna heaters:

  1. Harvia sauna control unit Kombi: This control unit is suitable for both normal Finnish sauna heaters and combi sauna heaters It is mounted outside the sauna cabin and has a temperature sensor that can be used to control the temperature of the sauna heater. It also allows the sauna lighting to be connected. The control unit is designed for sauna heaters with a switching capacity of up to 9 kW and offers infinitely variable temperature control from 40 °C to 110 °C. It can also control the humidity. The humidity in the sauna can also be regulated.
  2. Sauna control unit K2: This unit is specially designed for sauna heaters with an output of up to 9 kW. It offers infinitely variable temperature preselection from 40 °C to 125 °C and allows you to plan your sauna experience up to 24 hours in advance. This control unit is designed exclusively for connection to 400 volt sauna heaters

Modern functions and technologies in sauna control units

Modern sauna control units offer a variety of advanced features and technologies that make the sauna experience both safer and more enjoyable. From digital displays and touch controls to remote control via app, the latest models incorporate innovative technologies to maximise convenience and ease of use.

Digital displays, touch display and remote control via app

Many modern sauna control units, such as the Harvia Xenio Xafir Pro and the Sentiotec Pro series, have digital displays that enable precise control and monitoring of the sauna temperature. Some models also offer touch operation, which makes setting the sauna intuitive and user-friendly.

In addition, some advanced models allow remote control of the sauna via an app. This is particularly convenient as users can switch their sauna on and off or adjust the temperature and other settings from anywhere. Such systems are compatible with devices such as smartphones, tablets and even smart home assistants such as Alexa and Google Home.

Safety functions and temperature sensors

Safety is a key aspect of modern sauna control systems. The models include integrated safety functions such as automatic switch-off in the event of sensor breakage and short circuits. This prevents overheating and other potential hazards. The K4 Next sauna control unit, for example, offers a digital temperature display that enables real-time monitoring of the sauna temperature and is equipped with safety functions that ensure a worry-free sauna experience.

Practical tips for installing and using sauna controls

Installing and using a sauna control unit can seem complex at first, but with the right tips and information, it becomes a manageable process. Correct installation and connection are crucial to the functionality and safety of the system. In addition, understanding the various settings and operation greatly enhances the sauna experience.

Installation and connection

  1. Choice of location: The sauna control unit should be mounted outside the sauna cabin in a dry and well-ventilated environment to prevent damage from heat and humidity. Make sure that it is easily accessible.
  2. Electrical connection: Sauna control units require a safe electrical connection, which should be carried out by a qualified electrician. This is particularly important for higher outputs (e.g. sauna heaters over 9 kW).
  3. Temperature sensor installation: The temperature sensor, an essential part of the control unit, should be correctly positioned within the sauna cabin to ensure accurate temperature readings.
  4. Safety check: After installation, all components should be checked for proper function and safety to ensure that there are no risks such as short circuits or overheating.

Settings and ease of use

  1. Temperature and time control: Modern sauna control units usually offer a digital interface that allows you to set the temperature and operating times of your sauna easily and precisely. The settings should be adapted to your personal preferences and the specifications of your sauna heater.
  2. Use additional functions: Many combi control units offer additional functions such as fan and lighting control, humidity control and safety settings. Familiarise yourself with these functions in order to exploit the full potential of your sauna control unit.
  3. Ease of use: Ensure intuitive operation, for example by using touch control panels or remote control via apps, which can significantly increase ease of use.

By following these tips, you can ensure that your sauna control unit is optimally installed and that you enjoy the best possible sauna experience.
