EXT Stage Select - Two Air Conditioner/Heat Pump Units (Select Models) On 1 Zone
This system can be configured to run two air conditioner/heat
pump units using the same temperature set-point for controlling
the comfort level in one zone
One unit is designated as the primary stage and the other unit is
designated as the secondary stage. The power module boards in
both units will use the same DIP switch selection for the Zone
(for example, both will be set to Zone 2). On the unit designated
“secondary” the power module board DIP switch identified as
“Ext Stage” must be set to the ON position in order to configure
the power module board for the on-demand secondary stage
operation (in this example Zone 2 and Ext Stage DIP switches
are in the ON position). In this stage configuration, the CCC 2
thermostat temperature set-point will be used for both the primary and the secondary stage air conditioner/ heat pump. Only
one indoor temperature sensor is required for this configuration
and it must be installed in the power module board configured
as the primary control. The turn ON time for the compressors
and fans will be controlled to ensure that compressors on the
system start one-at-a-time. A minimum delay of 20 to 30 seconds is required between compressor starts

I replaced all 6 couplers. Yes, I did see corrosion on the couplers and connectors in the Zone 1 Heat Pump.
I cleaned all of the remaining connectors. I did not replace any of them. They were clean and shiny after the cleaning. Toothbrush and CRC Electronic Cleaner.
It was strange after cleaning the connectors and replacing the couplers I went down and did another initialize but had the same symptoms. I guess it's possible the connectors may have still been a little wet from the cleaner.
Understand now regarding the board connections.
Crazy all of the wire connections inside the plenums. Seems like a pretty sloppy way to do things. Should have used some kind of moisture proof connectors. Funny how it is actually getting hard to find RJ-11's. I bought all my local Menard's had and also the last one at Walmart.
Heading to Talladega tomorrow so I will try the Zone 3 thing again when I get back.
Thanks again!
