Can this be used in the 220V 50Hz?china

[roger1818]

No.  There is only a 120V 60Hz version for
use in North America.  There are three
issues.  Obviously the voltage difference
is the first issue.  The second issue is
that the clock is dependant on the 60Hz
signal and would run slow with 50Hz.  The
third issue is the European (and thus
presumably Asian) versions of X10 use a
different RF frequency for the RF remotes.

How to distinguish difference issue in  the
buy?

[holger]

it would be nice, if AHP would be produced
in a 220V/50Hz Version.
My one is working well on 50HZ, after the
Modification to 220V.
e.g. the Clock is definitely running
correct!

Mosquito:  I don’t understand what you are
asking.

Holger:  Interesting.  When you did your
modification, did you disconnect the signal
coming into or out of U4 or do you keep your
CM15A connected to your PC 24/7?  The former
would then have the time of day clock timing
based on the CY7C63723’s internal clock
similar to what happens in a power outage and
the latter would have the clock be
continuously updated by the PCs clock.

How are you checking the clock accuracy?  If
you are using reports from the PC, that can’t
be relied on, as the PC will almost certainly
have recently updated the clock in the CM15A.

How did you overcome the difference in RF
frequency?  Are you going to publish on the
web your modifications for others to use?  I
would be interested to see what you have done.

Holger:
How did you do your conversion?
Do you have any details available so that
it's possible to copy your work?

It's tragic that they killed the
developement for the AH in favour for AHP
that *only* works with hardware for 120V/60Hz
