When setting up a ComfortBridge™ furnace for use
with a Non-Communicating outdoor unit you must
set airow in the “ton” menu on the PCB or in the
CoolCloud HVAC APP. Failure to do so will result in
the furnace PCB displaying “IdL” and the blower will
not operate with a call for cooling. The Board does not
need to be replaced, you MUST set the airow rst.
EXTREMELY IMPORTANT: For two-stage gas heating, the
system only needs a single W input. Internal algorithms
will control staging of the gas furnace automatically based
on the single W input. For non-communicating outdoor unit
wiring see instructions below.
