Question: WS467(C3) on when WS467(C2) off

[wtell]

i have two ws467,one code is C2,one code is C3.
X10: TM751 houseCode set to C and one MS14A set to C2,one MS14A set to C3.
they work ok,but some times,ws467(C2) on(the MS14A of Code C2 trigged),delay 1 minute light off, another light(controled by C3 WS467) auto on.

how do i solve the problem ?

thanks.

The MS14A has a Dusk Dawn Sensor. It sends a On at Dusk and an Off at Dawn or if light is shining on it and fools it. This Dusk Dawn Sensor is on the Moston Sensors Address +1 Unit Code. So your C2 MS14A is sending on and off codes on C3 when dusk and dawn are sensed. C3 is your second Motion Sensors output. Try changing the C3 to C4. That will leave the dusk dawn address unused. Note the C4 sensor then has a C5 dusk dawn.

As Brian H indicated, it's not so much a problem as it is understanding how they work.
If changing the code isn't an acceptable solution, then you might try the tape method he and Puck described here* in response to a similar recent question.
