Title: CM15A will not turn lamp ON but MT13a does
Post by: rrio on November 14, 2010, 09:55:09 AM

I cannot get the CM15A to turn ON a lamp at a particular wall outlet to which I have a lamp module plugged.  I can, however, get the lamp to turn ON using a MT13A mini timer from the same outlet as where I connect the CM15A.  Is my CM15A generating a weaker ON signal, or is it defective?  Any advise and solutions?

If the lamp module is a soft start version. Where it ramps on and off.
Try defining the module in AHP as a LM14A.

I think I've tried that, but I'll try it again. Thanks, Raul

Yes, I do believe the CM15A has a weaker transmitter.

I wonder if there is a fix available or in the plans.

It could be a marginal X10 power line signal and the CM15A maybe slightly weaker.
Have you done any tests to see if you have signal suckers or power line noise makers?

I have seen a signal test of a CM15A and it was stronger than a few other X10 senders.

Though who knows with X10.
I do know the latest Lamp and Appliance modules along with the TM751 have been completely redone. With more readily available parts. Maybe the latest CM15As are also a redesign.

is it the timers and macros that doesn`t work?

if it so, try to name it on module def: lamp module (basic one).

for strange reasons some new modules don`t understand the extended codes transmitted, you have to change it for more basic ones especially if you have weak signal or transmissions just like the one transmitted by the CM15A
