Bypassing Capacitor For Low Wattage Devices


My low wattage device glows when the relay is off. 

Description/Explanation of Issue

This is due to a capacitor installed across the relay to meet CE requirements for larger wattage devices.


If you find that you need to install this dimmer with low wattage devices, the capacitor can be bypassed by moving the appropriate channels jumpers.

The jumper (circled red below) is located to the right of the relay on the Triac PCB:
