1. Inverter units using the
CoolCloud
HVAC phone
application or control board push button:
a. Inverter units are charged by setting
the CR9 menu (Charge Mode) to ON through
the furnace control board push buttons
or through the
CoolCloud
HVAC phone
application.
b. The System will remain in charge mode (high
speed) for 60 minutes before timing out.
c. The installer must manually shut off charge
mode once complete.
2. Two-stage outdoor units using the
CoolCloud
HVAC
application:
a.
Using the cooling icon after entering the outdoor
unit menus, energize the outdoor unit at 100%
capacity.
b. Charge the outdoor unit as required using the
charging information provided with the outdoor
equipment.

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.
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.
