This furnace is Bluetooth ready and functions with the
CoolCloud HVAC phone application designed to improve
the contractor’s setup / diagnostic experience. Users can
see specic 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 application will automatically
notify the user if updates are available.

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 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
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 properly without
this 24 VAC transformer.
