I have two Levitron HCM06-1D 1000W dimmers on two separate circuits. I have V572 and XTB-IIR.
I have these set to a dimmed level, so an ON command will turn ON the previously stored dim level, OFF command will go dark. I have minimum DIM level set, so I can easily manually reset stored DIM level to minimum DIM level if needed.
These have worked well for many months. Now I have problem.
After an ON command is issued, I get the stored DIM setting. However, some time later I find them at FULL ON. I reset to DIM level, and again, some time later I find I am at FULL ON. It’s like someone is playing a joke - setting FULL ON some time after I set DIM level.
I already know the routes and testing to do to find errant commands, noise, neighbor X10’s, etc., etc., etc. What I am looking for is OTHER non-command possible causes that I’d never find by searching for command related anomalies.
So, is there a condition these Levitron HCM06-1D 1000W dimmers can see to cause a reset-to-full-ON condition?
I will disconnect all X10 controllers from the house, turn the Levitrons on by hand, and monitor X10 traffic with XTBM. If I get the behavior with no X10 commands, I’m going to think it’s some other non-command cause.
