The UM506 Universal Module plugs into an AC
wall socket and can receive X10 On/Off
signals over the power line. It has a SPST
low-voltage relay (5A, 24VDC or 100VA, 30VAC)
for an output which can be configured for
either continuous or momentary (about 1 sec)
operation. Assuming that one momentary relay
closure suffices for both opening and closing
the blinds, you'll need one module for each
window to be controlled, and two AC sockets -
one for the module and one for the blind
motor.
Each X10 housecode can control up to 16
different units, so you'll need to use 2
housecodes, and probably two different
remotes since it's a pain to constantly
switch back and forth between housecodes on
one remote. Or you could use around 10 SS13A
"Stick-A-Switch" (each can control 3 modules)
.
Depending on the size of your house, the
ActiveHome Pro (CM15A) interface may not have
sufficient RF reception range to receive an
RF signal from anywhere in the house. You
may want to take a look at the WGL V572A all-
housecode transceiver (
www.smarthome.com).
However if you're planning to control the
blinds via downloaded timers and macros in
the CM15A, that ought to work for the entire
house (with the addition of a phase coupler).
