I was not suggesting that the soldering method was the cause of my issues. As I had the same problems when I connected my relay output wires to pins 2/4 on the satelite connection port. Everything would work for a while and then after a while start to become faulty. I only mentioned the orientation of the units regarding sunlight as it was my observation that the faulty condition appeared to occur only during mid/late afternoon when the sun was strongest so that there seemed to be some correlation there. I wondered about the sun/IR problem and covered the eye with elec tape but did not help (Unit continued to cycle). I also wondered whether the other aspect of the sun's position (heat) was the culprit in some way, altering behaviour of circuitry and wiring (reduced resistivity).
At any rate it IS very bizarre. The units are not damaged as they work perfectly well under all conditions as before using the remote and manual button provided that:
Unit 1 does not have any length of wire attached to the internal switch (it still has the short pigtail wires soldered to the switch, but i needed to cut it from the 12ga speaker wire installed through the walls and down 3 stories to the utility rm where the relay controller is.
Unit 2 is still connected to all wiring but diconnected from the relay output.
Unit 3 is connected to my relay output and can function 100% this way with either automated relay control or manual/IR operation.
I contacted ESI yesterday and it looks like the product you had suggested is for my older non-platinum powerrise units, but won't work in my application as it requires a 3-wire connection and I only have 2-wire in place. At any rate, I have to resolve the cause of my issues due to internal wall wiring before I could implement anything further. I would need to do further troubleshooting by swapping out blinds and exchanging connections between relay outputs, wall wiring and blinds to get to the root cause, however this would be very time consumming so I was hoping someone had a whizzy bang answer : )
My current theory is that there may be a partial short in the in-wall wiring (staple through the jacket...) that manifests when sufficient heat allows subtel movement in conductors around the staple..... or, the length of unshielded wiring is picking up some elec noise which does something to the circuitry on the motor board???
Unfortunately I have not been able to talk to anyone at Hunter Douglas that is REALLY technically savvy on the detailed design/operation of powerrise that could understand my conditions and make some probable suggestions.... ie when my unit1 goes into a continuous cycle mode: up/down/tilt/up, this is not a condition that can occur from a continuous closure of the manual button (as in a dead wire short) - it is like some special demo/test mode that can be selected by program/switch setting only...
