This furnace is Bluetooth ready and functions with the Cool
Cloud HVAC phone application designed to improve the con-
tractor’s setup / diagnostic experience. Users can see spe-
cic model information, review active diagnostic error codes,
observe system status during operation, make system menu
adjustments, add site visit notes and run system testing of all
operational modes (heat / cool / fan) directly from the phone.
The phone application is also capable of directly updating the
furnace software anytime updates are available. The applica-
tion will automatically notify the user if updates are available.
NOTE: The software update may take up to 20 minutes to
complete.

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. Inter-
nal algorithms will control all available cooling and heating
stages including dual fuel operation based on these inputs.
Any single-stage 24VAC thermostat can be used. For
proper operation the thermostat must be setup to control a
single-stage AC outdoor unit and to control a single stage
gas furnace. 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. 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 ther-
mostat connector on the furnace control as instruct-
ed 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.
