The settings of the dimmer module are determined by placing a shunt (=jumper) over pins 1-2 or 2-3 of JP1,

2 and 3 (see figure 1.0). The operation of the device becomes unstable if the jumpers are not mounted.

JP1 – Memory function:

The last used luminous intensity is stored in the memory if this function is activated.

1-2: Memory function is deactivated.

2-3: Memory function is activated.

JP2 – Safe min. luminous intensity:

This function is designed to make sure a lamp doesn't burn at too low a luminous intensity for too long. This

function offers two distinct advantages: first of all, the life of a halogen bulb is not shortened unnecessarily

because it's working at too low a temperature. Furthermore, it doesn't really matter if a lamp escapes your notice

because of its limited luminous intensity. The lamp will be extinguished automatically after a certain time.

1-2: This function is deactivated.

2-3: This function is activated.
