[delta 4 dimmers]

Many thanks for your help. I successfully trimmed the dimmers using the pot. It was generating 25volts ac for zero control voltage. It will be interesting to see if it wanders off again. if it does then I will replace the unit.

We have long since lost the manual for the delta4 that runs some of our house lighting. The dimmers are not going off properly at zero control volts. Is the unit trimmable? I can see one single pot on the pcb but have not yet plucked up courage to adjust it.
