tion box all the way back to the electrical panel. NOTE: Do not
use gas piping as an electrical ground. To confirm proper unit
grounding, turn off the electrical power and perform the follow-
ing check.

This furnace is Bluetooth ready and functions with the Cool
Cloud HVAC phone application designed to improve the
contractor’s setup / diagnostic experience. Users can see

codes, observe system status during operation, make sys-
tem 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.
NOTE: The software update may take up to 20 minutes to

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 heat-
ing calls (including dual fuel applications) the system only
requires a single W input from the thermostat. Internal al-
gorithms will control all available cooling and heating stages
including dual fuel operation based on these inputs. Any
