Quick Start Guide For Communicating
Outdoor Units
EXTREMELY IMPORTANT:
For all cooling calls, the
system only requires a single Y input from the thermostat.
For all heating calls (including dual fuel applications), the
system only requires a single W input from the thermostat.
Internal algorithms will control all available cooling and
heating stages, including dual fuel operation based on
these inputs. Any single-stage 24VAC thermostat is
applicable. For proper operation, set up the thermostat to
control a single-stage AC outdoor unit and a single-stage
gas furnace. The control board does not accommodate an
O wire thermostat input (reversing valve signal). If using a
heat pump, set up the thermostat, as stated above. Setting
the thermostat for the heat pump control or multi-stage
control may result in incorrect performance.
1. Connect all necessary thermostat wires to the
thermostat connector on the furnace control, as
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
appropriately without this 24 VAC transformer.

Download the
CoolCloud
HVAC phone application for
charging and to configure/test system operations.
NOTE: When new versions of Bluetooth
Communication Software and Furnace Control
Software are available, the phone application
notifies the user. Software updates are classified
as either optional or mandatory and installed by
using the phone application. Ensure installation
of all mandatory software updates. Review notes
for optional software updates and install if
necessary.
NOTE: If an E11 code exists for the inverter system
immediately after line voltage is applied (code
shown in the CoolCloud HVAC phone application
or displayed on the inverter control), the System
Verification Test needs to be completed before
any other operation. See the following procedure.
1. Allow the system to remain Idle for 5 minutes.
2.
Turn the system verification test on either by using the
CoolCloud phone application, or by entering the
SUt
menu through the furnace pushbuttons.
3. Wait for the test to complete.
Charging
1. Inverter units using the
CoolCloud
HVAC phone
application or control board push button:
a. Charge the inverter units by setting the CR9 menu
(Charge Mode) to ON through the furnace control
board pushbuttons or 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.
