Hi all
I wonder if anyone has had something like this happen before.......................this is what I said in a support ticket to the (UK) manufacturers of the dimmer switches. These are Varilight V-Pro dimmers
Hi
Ref: model MJP120
I hope you can throw some light (no pun intended) on the way two of our V-Pro dimmers are behaving.
Yesterday 29th November, I upgraded all 4 off dimmers in our house as we were changing to using dimmable LED bulbs (currently all 13W Philips CorePro lamps). Note ~ all purchased from CEF.
We have a modern consumer unit (fitted a few years ago) with separate circuit breakers for the downstairs lights and the upstairs lights wiring.
The strange behaviour is as follows:-
* It only affects the downstairs dimmer units.
* There is one dimmer in the sitting room and another one in the dining room.
* With both the sitting & dining room lights on together with the kitchen light (this is tube fluorescent with a single toggle switch), we find that when the kitchen light is turned off it will turn off these other two lights....but not always both of them!
* The behaviour is slightly random in that it does not happen consistently i.e. sometimes ~ no such effect, or only one of them goes off, or both lights go off.
* Following that trigger event, the dimmers will not switch on the lights with the initial press of the dimmer button and require a second press of the button to turn on the light(s).
* We never had this happen with the old style dimmers used with tungsten or the more modern halogen energy saver bulb.
IMO and perspective
It is like the kitchen light switch is triggering a pulse in the lighting circuit that is causing the dimmers to failsafe to a sort of reset state. Now, I think I once read that fluorescent tube "starter units" can go wrong and cause issues but that is when they 'start' i.e. the light switched on but not 'off' causing any issues.
So in advance of the manufacturer replying with their wisdom............................I thought I would pick the collective TPers brains
TIA
