DESIGN AND OPERATING PRINCIPLE

CBF LP 200/250 T/TH/TP

CBF LP 200/250 Light T/TH/TP

The fan casing is made of galvanized steel. The fan casing includes an exhaust spigot with a back draft damper to prevent back airflow. The terminal box comprises the terminals for wiring of the fan and is attached to the fan casing. The decorative grille is fixed to the casing via the springs inserted to the holders. The front panel is fixed via the grille slots. A single-phase electric motor with a centrifugal impeller with forwarding curved blades is fastened inside of the casing. Depending on the fan model the fan may be equipped with a LED lamp, a timer, a humidity or motion sensor.

Timer (t)
After an external switch, e.g. a light switch is turned off, the fan is turned on or goes to high speed after a countdown of a set turn-on delay time, adjustable from 0 to 3 minutes.
After the fan is turned off it keeps running for a set turn-off delay time, adjustable from 1 to 90 minutes, and then reverts to the initial operation status.

Motion sensor (tp)
In case of activation of the motion sensor the fan turns on or switches to a higher speed.
After no motion is detected the fan keeps running for a set turn-off delay time, adjustable from 1 to 90 minutes and then reverts to the initial operation status.

Humidity sensor (th)
If the indoor humidity exceeds the set humidity point adjustable from 50 % up to 90 %, the fan either turns on or goes to a higher speed. After indoor humidity drops down the fan keeps running for a set turn-off delay time, adjustable from 1 to 90 minutes, and then reverts to the initial operation status.

MOUNTING AND SET-UP

READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT.

• The fan is a component part and is not designed for stand-alone operation.
• The fan is constructed for ceiling installation in the floor slab and fixation to the interjoist with the distance between the ceiling joists from 270 up to 470 mm using the removable fixing brackets or the fastening holes in the fan casing.
• The installation place must be in compliance with local construction norms for units of this type.
• Check the fan for mechanical damages prior to mounting.
• Make sure that the casing comprises no foreign objects, such as paper or foil.
• While mounting the fan sufficient service access for maintenance or repair operations must be provided.

The minimum gap between the fan and the ceiling is 5 mm.

MOUNTING STEPS

1.  Attach the fan to the interjoist using the screws.
   Vertical attachment to the beams on the wall is permissible.

2. Connect the air duct of the required diameter.

3. Connect the LED lamps (included in the delivery set) for the Light models.
   Option: connect the humidity sensor or the motion sensor (specially ordered accessory).
   For the Light models: connect the power socket of the LED lamp and the respective sockets in the terminal box. For the TH models with a humidity sensor: remove the protective cap from the grille prior to its installation. Route the contact socket of the sensor TH or TP via the opening in the grille and connect the sensor socket to the respective contact socket on the control unit.
   Fix the sensor in the grille opening and cover the opening with a protective cap.

4. Install the decorative grille on the fan casing using the holders on the casing.

CONNECTION TO POWER MAINS

• POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. THE UNIT MUST BE CONNECTED TO THE POWER SUPPLY BY A QUALIFIED ELECTRICIAN. THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.
• ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.

The fan is rated for connection to a single-phase AC 220-240 V 50/60 Hz power supply. The fan must be connected to power mains using durable, insulated, and heat-resistant conductors (cables and wires) via the circuit breaker QF integrated into the house cabling system. The external circuit breaker installation place must ensure unhampered access for emergency shutdown of the unit.

WIRING DIAGRAMS

ACCESS TO THE TERMINAL BOX FOR WIRING THE FAN

Remove the decorative grille
For accessing the connection terminals loosen the screw on the terminal box lid and take the lid off.

Remove the protective cap and install the cable gland.

CONTROL

CONTROL UNIT WITH A SPEED SWITCH

The fan with AC motor is controlled by a three-position switch. The switch has three positions:

• OFF — the fan is turned off.
• LOW — the fan operates at the reduced performance (speed 1).
• HIGH — the fan operates at maximum performance (speed 2).

When the power is turned on (~ 230 V), the fan will operate in one of the above modes.

MICROPROCESSOR CONTROL UNIT WITH INDICATION
The AC fan motor is operated by a microprocessor control unit. The front panel of the control unit comprises a light indicator, control buttons, and two connectors for the connection of the humidity and motion sensors.

After the fan is connected to the power supply, the indicator displays for two seconds. After that, the light indicator goes off and the fan starts operating in set mode. Once the button  F is pressed the indicator displays the turn-off delay timer setting , the first Setup menu entry. Use or buttons to navigate in the Setup menu. Press  F , to select a current entry in the Setup menu. After that the indicator displays the selected parameter value (e.g., turn-off delay timer setting). Use or to change the value. Press  F to come back to the Setup menu. If no button is pressed for 60 seconds, the indicator goes down.

Example
The indicator displays . Once the button is pressed, the Setup menu list goes one position down and the symbol is displayed (refer to the Setup menu). Once the button  F is pressed, the indicator displays the turn-on delay timer setting, which can be edited with the buttons and . Once the button F is pressed again, the Setup menu is displayed again and the edited value is saved.

To reset the menu to the factory settings press and hold the buttons  F and synchronously. In 5 seconds the indicator displays , and goes off. The fan keeps running in normal mode with the factory settings.

INDICATOR SYMBOLS OF THE MICROPROCESSOR CONTROL UNIT

• turn-off delay timer adjustable from 1 to 90 minutes (default setting 15 minutes).
• turn-on delay timer adjustable from 0 to 180 seconds with an increment of 10 seconds (default setting 0).
• humidity set point adjustable from 50 % up to 90 % (default setting 75 %).
• access to the submenu of the fan operation mode.

Operation mode — the fan operates without any activation signal from the switch, humidity or motion sensor. Operation mode — the fan operates with an activation signal from the switch, humidity or motion sensor. — back to the upper setup menu level.

Once the switch is turned on or the humidity or motion sensor is activated, the fan switches from the mode to the mode . After a signal is no more received from the sensor in case of the indoor humidity normalization, or no more motion is detected in case of the fan shutdown, the fan keeps running for a set turn-off delay time and then switches from the mode to the mode .

SETUP OF THE OPERATION MODES AND

The and modes can take the following values for the fan with an AC motor:

• — the fan is turned off.
• — the fan operates at reduced performance.
• — the fan operates at maximum performance.

Example 1
— with these activated settings the fan is constantly turned off. Once the switch is turned on or a sensor is activated, the fan starts to run at reduced performance.

Example 2
— with these activated settings the fan runs at reduced performance. Once the switch is turned on or a sensor is activated, the fan starts to run with the maximum capacity. This setting is factory set and is the default setting.
