BN30 socket thermostat

Plug in. Set room temperature. That's it!

Socket thermostat with temperature sensor

The thermostat BN30 enables temperature control of heating devices and air conditioners in steps of half a degree from 5 °C to 30 °C. To this end, simply plug the socket thermostat in between the heating device or air conditioner and a socket, and select the desired temperature. Via its integrated sensors, the device measures the current room temperature and regulates the heating device or air conditioner according to the desired nominal value.

The extremely simple handling and programming of the device enable a multitude of possible applications – for example, the BN30 is particularly suited for mobile heaters.

The respective current room temperature can be read conveniently from the large overview display, and the heating device or air conditioner can also be switched off permanently by the thermostat.

Moreover, the BN30 is fail-safe thanks to an integrated EEPROM making sure that the selected settings are maintained in the event of a power failure.

Practical tip: Ideally, the BN30 should be plugged into interior walls.

Examples of use:

Note: Connected consumers are switched to zero potential when the device is switched OFF and must be provided with an automatic restart function.

BN30 – Special equipment features

BN30 socket thermostat
The BN30 socket thermostat offers regulation of the temperature of air-conditioning and heating units in the range from 5 °C to 30 °C in 0.5 °C steps.
BN30 socket thermostat
The operation of the BN30 is intuitive. The socket thermostat is quickly and easily placed between the electrical appliance and the socket. Then all that remains is to set the desired temperature.
BN30 socket thermostat
The sensors in the BN30 measure the room temperature at 10-second intervals and regulate the connected heating or air-conditioning unit according to the programmed target value.
BN30 socket thermostat
The BN30 socket thermostat has an integrated EEPROM (Electrically Erasable Programmable Read-Only Memory). This means that the selected settings are retained in the event of a power failure.

Application examples

BN30 socket thermostat
Whether electric fan heater, infrared radiator or hot plate - in the operating mode "Heating", the socket thermostat BN30 activates the connected heater until the desired room temperature is reached.
BN30 socket thermostat
Pleasant coolness in the office, in shops or at home - in the "cooling" mode, the BN30 socket thermostat activates the connected cooling device until the predefined target temperature in the room is reached.

Before purchasing the room thermostat, think about the applications for which you want to use the room thermostat. Also make sure that the heating or cooling appliance to be controlled is suitable for use with an external room thermostat.

As a general rule: Electrical devices that do not restart automatically after a power interruption are not suitable for use with an external room thermostat!

A digital socket thermostat like the socket thermostat BN30 is characterized by its simple handling and programming. When the desired target temperature has been set, the thermal sensor installed in the thermostat head measures the actual value of the room temperature and regulates the heating device or air conditioner connected according to the desired target value.

Characteristics of the digital socket thermostat BN30:

  • Suited for heating and cooling control
  • Operating range from 5 °C to 30 °C 
  • LCD display with temperature indication
  • Simple handling and programming
  • Permanent shutdown of the consumer
  • Favourable purchase costs


For the convenient control of several mobile devices with plannable switching times, we recommend the use of a multifunctional device like the radio thermostat BN35. The radio thermostat comprises a radio-controlled socket (receiver) and a radio handheld transmitter (transmitter). The radio thermostat in the handheld transmitter always measures the current room temperature of its surroundings. With the radio thermostat BN35, up to 100 switchable and adjustable radio-controlled sockets can be controlled simultaneously with only one transmitter over a range of up to 20 metres.

Characteristics of the digital radio thermostat BN35:

  • Suited for heating and cooling control
  • Convenient timer function
  • Separate handheld transmitter and receiver
  • Operating range from 0 °C to 70 °C
  • LCD display with temperature indication
  • 2-pin safe switching
  • Extensive programming options
  • Switches up to 100 radio-controlled sockets in parallel 
  • Permanent shutdown of the consumer
  • Remote operation
  • Automatic frost protection system
