This air handler is Bluetooth ready and funcons with the Cool
Cloud HVAC phone applicaon designed to improve the contrac-
tors setup / diagnosc experience. Users can see specic model
informaon, review acve diagnosc error codes, observe system
menu tesng of all operaonal modes (heat / cool / fan) directly
from the phone. The phone applicaon is also capable of directly
updang the air handler soware anyme updates are available.
The applicaon will automacally nofy the user.
NOTE: The soware update may take up to 20 minutes to complete.

EXTREMELY IMPORTANT: For all cooling calls the system only re-
quires a single Y input from the thermostat. For all heang calls
(including applicaons with backup electric heater kits) the system
only requires a single W input from the thermostat. Internal algo-
rithms will control all available cooling and heang stages based
on these inputs. Any single-stage 24VAC thermostat can be used.
For proper operaon, the thermostat must be setup to control a
single stage AC outdoor unit and to control single stage electric
heat operaon. The control board does not accommodate an O
wire thermostat input (reversing valve signal). If a heat pump is
installed, the thermostat should be setup as stated above. Seng
the thermostat for the heat pump control or mulstage control
may result in incorrect performance.
1. Connect all necessary thermostat wires to the thermostat
connector on the air handler control as instructed by the
applicable wiring diagrams shown in this secon.
2. Connect the 1 & 2 wires between the indoor and outdoor
unit for communicang operaon.
Note: Verify two stage outdoor units include a 24VAC
transformer (for outdoor control board power). Two stage
outdoor units may not behave properly without this 24 VAC
transformer.

3. Download the Cool Cloud HVAC phone applicaon for
charging and to congure /test system.
NOTE: When new versions of Bluetooth Communicaon Soware
and Air Handler Control Soware are available, the phone appli-
caon noes the user. Soware updates are classied as either
oponal or mandatory and installed by using the phone applicaon.
Ensure all mandatory soware updates and install if necessary.
16.1 Charging
1. Two-stage outdoor units using the Cool Cloud HVAC appli-
caon:
a. Using the cooling icon aer entering the outdoor
unit menus, energize the outdoor unit at 49%
capacity or lower.
b. Charge the outdoor unit as required using the
charging informaon provided with the outdoor
equipment.

EXTREMELY IMPORTANT: For two stage electric heat kit control
the system only needs a single W input. Internal algorithms will
control staging automacally based on the single W input. For
non-communicang outdoor unit wiring, see instrucons below:
1. Use the wiring diagrams on the next page to connect low
voltage thermostat wires.
NOTE: When installing the air handler with a non-com-
municang heat pump, wire directly to the “O” terminal
on the non-communicang heat pump. See the following
gures.
