I have the new one now but have not yet installed it -- waiting for a
new door to be installed. The only *visible* changes are the different
wall-mount control and the hard-wired power cord instead of being
removable at the opener end.

I do see that the new wall control is claimed to be compatible with
their Z-Wave system, but I haven't read up on that yet to know what
advantage that offers.

Actually the salesman (it was the same guy who sold me the unit 5 years ago)
told me that they had made dozens of improvements. They are also coming out
with a slightly more powerful unit that integrates with their wireless
control system. In any case the new units have been working fine for me but
I would want Wayne Dalton to install it. I would not dare do it my self.
And as I said two units needed a synchronization fix of the gears because
the locking arm was coming down at the wrong time as delivered by the
factory. By the way the motor is in the moving arm.


Although ours was purchased only about three years ago, it was in fact a
5-yr old one, according to the Date of Manufacture label: 0903.

I know that at some point during those two years they changed the
light-activation mechanism from infra-red to radio-frequency. Also the
wall-mounted control gained some new features: e.g., the lock-out switch.

Perhaps during those five years they have made mechanical improvements as
well and the replacement will last us for many years.
