Well more to the story. Around 5AM the AC shuts off. All of them with E1 error.
So I ended up replacing and cleaning all 3 units now with new couplers in all of them. After that I did an Initialize and it did not recognize any of the zones. Went up and put the Middle AC back on Ext. stage instead of Zone 3. Did another initialize and is working as was originally.
One other thing I did was swap the RJ-11 cables on the middle AC relay board because I think I may have swapped them. Not sure if it makes a difference?
Another observation was that the Blizzard Heat Pump only had Heat Pump and Furnace Dip switch settings on. No zone 1 or EXT. stage on. I figured one or the other would have been on?
So now I am a bit confused. I don't know if it was the RJ-11 couplers, the dip switch settings on the middle AC, or a swapped RJ-11 on the middle AC relay board that caused the issue this morning.
Any input is welcome!
