Control panel for CBF LP fans

Manual control

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

Automatic control

• Timer: the fan constantly operates in Mode 1. When the light switch is closed, the fan switches to Mode 2 after the end of the turn-on delay time (from 0 to 3 minutes). Upon the light switch opening, the built-in turn-off delay timer keeps the fan running in Mode 2 from 1 to 90 minutes. On elapsing of this period the fan reverts to Mode 1. Timer and humidity sensor (available separately): the fan constantly operates in Mode 1.
• If the indoor humidity level exceeds the sensor threshold value set in the 50-90 % 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 1 to 90 minutes. On elapsing of this period the fan reverts to Mode 1. Timer and motion sensor (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 1 to 90 minutes. On elapsing of this period the fan reverts to Mode 1.

• The fan is designed for ceiling mounting.
• The fan is attached to the ceiling joists with spacer brackets and self-tapping screws.
• The flexible air duct is connected to the fan exhaust spigot through a clamp.
• The reduced casing height allows fans to be installed in ceilings with a thickness of minimum 140 mm.
