• CBF LP Light: basic model with a two-speed motor.
• The CBF LP Light T unit is equipped with an adjustable turn-on and turn-off delay timer. A humidity sensor or a motion sensor (available separately) can be optionally connected to this fan modification.

The built-in control panel of the CBF LP Light T fans enables setup of the following parameters:

• timer-based turn-on delay
• timer-based turn-off delay
• humidity level
• air flow in Modes 1 and 2.

Control panel for CBF LP Light 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.
