Quick Start Guiide For Non-Communicating
Outdoor Units
When setting up a ComfortBridge™ furnace for use
with a Non-Communicating outdoor unit you must
set airflow 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 airflow first.
instructed by the applicable wiring diagrams shown in
this section.
2. Connect the 1 & 2 wires between the indoor and
outdoor unit for communicating operation.
Note: verify two stage outdoor units include a 24 VAC
transformer (for outdoor control board power) Two
stage outdoor units may not behave properly without
this 24 VAC transformer.
