Re: Making an X-10 lamp module immune to dimming

["Jeff Volp" <JeffVolp@xxxxxxx>]

IC pin 8 is the output that drives the triac.  The delay of that pulse with
respect to powerline zero crossings determine the brightness.  It is not
clear how they adjust the phase, but it is probably done by some sort of
timer in the IC whose count for each half cycle is a function of the dim
level.

Since older lamp modules come on at full brightness, the problem only occurs
if they are manually sent dim commands.  Either just don?t do that, or put
them on their own housecode where they can?t be directly accessed.  Then
have your Ocelot or HV map manual commands to only ON/OFF on that housecode.
The macro can also handle the ?ALL? issues.

We have a bunch of lamp modules that are only used for ON/OFF control.  Most
power CFLs, but one runs our hot-water recalculation pump.  Can you imagine
CLACK - - - -CLACK every 15 minutes from an appliance module?
