Fancom VLR.20d Manual page 6

The VLR.20d 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)

Heating elements (period control)
Install the VLR.20d and associated components as follows:
1. Mount the VLR.20d (see page 3)
2. Connect the VLR.20d (see page 3)
3. Test the VLR.20d (see page 4)
When mounting/installing the VLR.20d, the following should be observed:
Never mount the VLR.20d in a room where animals are present because of the (manual) control.
Place the VLR.20d at such a height that the manual control can be used.
Mount the VLR.20d on a flat surface.
Make sure that the gland nuts are at the bottom of the VLR.20d.
Seal all gland nuts after connection of the VLR.20d to prevent entry of dust, aggressive gases and/or
humidity
The VLR.20d 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.
