Stepless Variable Control Unit for Vario Wall-Mounted Ventilators
The CREN control and regulation unit is an stepless speed controller for Vario wall-mounted ventilators. Using the integrated phase angle control, the fan speed can be adjusted comfortably and precisely. Additional control functions such as reversing, natural ventilation and automatic operation are also available. Installation is carried out surface-mounted and is suitable for standard flush-mounted boxes.
Flexible & Infinitely Variable Control
Vario wall-mounted ventilators are speed-controllable. With the CREN, the output and fan speed can be adjusted continuously.
- stepless speed control (phase angle control)
- Reversing – change of airflow direction (supply / exhaust air)
- Natural ventilation (damper opening)
- Automatic operation in combination with C sensors
Application Note
The technical principle of phase angle control may cause a slight humming noise at low speed levels with certain motors. In noise-sensitive areas such as bedrooms or living spaces, the use of a 5-step control unit for Vario ventilators (CR5N) is recommended as an alternative.
