Stella F – Bidirectional radio protocol

  • sensor, regulator and actuator, all in one
  • self-sufficient, energy efficient room control is possible
  • save up to 30% in heating costs
  • wireless
  • radio controlled (proprietary)
  • bidirectional radio communication
  • easy to install due to the snap-on adapter system
  • actuating time just about 3s/mm
  • nearly noiseless gear
  • maximum lift of valves: 4,5 mm
  • automatic frost protection
  • "open window" detection
  • disassembly protected by security mechanism
  • only use the supplied tools to open/removable
  • battery operation: 2 x AA battery (battery life up to 2 years*)
  • 2-year guarantee 
  • connection: M 30 x 1,5
  • fits on a lot of well known lower valve parts 
    (e.g. Heimeier, Danfoss, Honeywell Braukmann, Honeywell 
    MNG, Oventrop from approx. 1996 among others)
  • adapters for different types of valves available
  • casing: synthetics ASA, similar RAL 9016, white

Stella F+ 

  • technical features correspond to Stella F
  • available with 4 batteries (battery life* is thereby extended)
  • disassembly protected by security mechanism (anti-theft system), 
    secure battery cover for the industrial sector

* (depending on the profile of heat distribution and climatic conditions such as the existing external temperature during the heating period and the duration of the heating period and the valve used)


Wireless actuator suitable for heating, ventilation and air conditioning systems

Stella F and Stella F+ are produced in five different versions: Stella proprietary, Stella enocean, 
Stella KNX (RF), Stella zigbee and Stella z-wave. Each of the actuators is radio controlled and has 
low power consumption levels. The actuators have a snap-on closure, feature low noise levels 
and can be installed quickly and easily.

  • operating voltage: 3V (2 x AA battery)
  • actuating power: max. 120 N
  • ambient temperature: 0-50°C
  • media temperature: max. 100°C
  • CE compliant according to:  EN60730
  • protection class: IP20
  • RT+T directive
  • dimensions (W x H x D): 65 x 65 x 48 mm
