Before installing and commissioning the VLR.20, read the safety instructions, provisions and conditions carefully.
This paragraph contains a number of general safety instructions. The installation of the device and remedying of any
malfunctions should be performed by acertified electrical installer according to the applicable norms. The guarantee
does not apply if this product is installed in any other way than is indicated by Fancom.
Disconnect power before installation.
Prevent electrostatic discharge (ESD) when working on the VLR.20. Ensure that the workplace is clean
and dry.
Use correct wires as shown in the connection diagrams.
Make all wiring connections and check them before applying power. Incorrect connections can cause
permanent damage.
Make sure that the VLR.20 is well and properly grounded according to the guidelines.
Never place the VLR.20 in a place where the weather has direct influence (not in the sun, not in places
where the temperature can rise sharply etc.).
Inspect the VLR.20 periodically for any damages. Notify your installation technician immediately of any
damages. A damaged VLR.20 is unsafe!
Do not use water or high pressure cleaners for lengthy periods.
It is advisable not to switch off the VLR.20. This could lead to condensation caused by cooling down.

The VLR.20 is a power controller for the control of:
1-phase voltage controllable (triac) fans
Electronically controllable lighting (incandescent lighting and controllable fluorescent lighting)
Heating lamps (phase angle control)
Install the VLR.20 and associated components as follows:
1. Mount the VLR.20 (see page 3)
2. Connect the VLR.20 (see page 3)
3. Test the VLR.20 (see page 4)
When mounting/installing the VLR.20, the following should be observed:
Never mount the VLR.20 in a room where animals are present because of the (manual) control.
Place the VLR.20 at such a height that the manual control can be used.
Mount the VLR.20 on a flat surface.
Make sure that the gland nuts are at the bottom of the VLR.20.
Seal all gland nuts after connection of the VLR.20 to prevent entry of dust, aggressive gases and/or
humidity
The VLR.20 is set as standard as an 10-0Vdc analog control. When this control changes into a 0-10Vdc control,
jumper J3 should be changed; see jumper setting. The manual operation connection should also be changed. This
means that the red (RD) and blue (BL) wire should be changed around.
Fancom advises the following controls with applications:

The VLR.20 has four jumpers with which different settings can be made. The factory setting is for fan(s) with DSR
feedback.
Disconnect the power for the VLR.20 before setting the jumper(s).

1. Switch off the power supply to the end station.
2. Control the jumper positions.
3. Switch on the power supply.
4. Set switch and knob to “aut”.
5. Turn potentiometer P1 on the CMV-board completely counter- clockwise.
6. Turn potentiometer P2 on the CMV-board completely clockwise.
7. Set the knob on the front to "man." and turn until the fan starts running.
8. Using potentiometer P2 adjust the minimum voltage between "U" and "V" so that the fan is barely running. A
Fancom fan is normally 2-wire connected and the voltage between "U" and "V" not set below 60Vac. (With a
3-wire connection , do not set the Fancom fan below 45Vac).
9. Turn the knob on the front to a minimum position (not to "aut."), until the fan stops running.
10. Using potentiometer P1 adjust the minimum voltage between "U" and "V" (for a Fancom fan, not below 55Vac).
If the fan is to stop running at 0% control, do not carry out steps 9 and 10. The fan may only stop running
completely with a 2-wire connection.
1. Switch off the power supply to the end station.
2. Control the jumper positions.
3. Switch on the power supply.
4. Set the switch and knob to “aut”.
5. Turn potentiometer P1 on the CMV-board completely counter-clockwise (and leave it in this position).
6. Turn potentiometer P2 on the CMV-board completely clockwise.
7. Set the knob to "man." and turn until the fan starts running.
8. Using potentiometer P2 adjust the minimum voltage between "U" and "V" (for a Fancom fan, not below
30Vac).
1. Switch off the power supply to the end station.
2. Control the jumper positions.
3. Switch on the power supply.
4. Set the switch and knob to “aut”.
5. Turn potentiometer P1 on the CMV-board completely counter-clockwise.
6. Turn potentiometer P2 on the CMV-board completely clockwise.
7. Set the knob to "man." and turn until the lighting is barely on.
8. Using potentiometer P2 adjust the minimum voltage between "U" and "V" (You determine the minimum lighting
position).

Fancom advises 2-wire connection of Fancom fans. If the fans are connected parallel, heat production
per fan may increase (causing a shortened working life). Fancom therefore advises not to parallel switch
more than three fans. See connection diagrams.
