Dometic CCII Control Board for Penquin II
Hi, new here to the forum. One of my roof AC units quit. It doesn't do anything. I measured voltage on the board (115VAC) but nothing coming out of the board. The board has P/N 3312227.000 on it. A...

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
