Manual control

  • The fan is controlled by means of the P2-10 speed switch (available separately).

Automatic control

  • The CBF modification with a timer T: The fan constantly operates in Mode 1. Mode 2 is triggered by the light switch closing. Upon the light switch opening, the built-in turn-off delay timer keeps the fan running in Mode 2 from 2 to 30 minutes. On elapsing of this period the fan reverts to Mode 1.
  • The CBF modification with a timer and an optional humidity sensor TH (available separately): the fan constantly operates in Mode 1. If the indoor humidity level exceeds the sensor threshold value set in the 60- 90 % range, the fan switches to Mode 2. When the humidity level reverts to the pre-set value, the built-in turn-off delay timer keeps the fan running in Mode 2 from 2 to 30 minutes. On elapsing of this period the fan reverts to Mode 1.
  • The CBF modification with a timer and an optional motion sensor TP (available separately): The fan constantly operates in Mode 1. If the motion sensor detects movement within its range, the fan goes to Mode 2. When the movement is no longer detected, the built-in turn-off delay timer keeps the fan running in Mode 2 from 2 to 30 minutes. On elapsing of this period the fan reverts to Mode 1.
