16 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 applications with backup electric heater kits) the
system only requires a single W input from the thermostat.
Internal algorithms will control all available cooling and heating
stages 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 single
stage electric heat operation. 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 multistage 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 section.
2. Connect the 1 & 2 wires between the indoor and outdoor
unit for communicating operation.
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 application for
charging and to configure /test system.
NOTE: When new versions of Bluetooth Communication Soft-
ware and Air Handler 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 all mandatory software updates and install if
necessary.
16.1 Charging
1. Two-stage outdoor units using the Cool Cloud HVAC
application:
a. Using the cooling icon after entering the outdoor
unit menus, energize the outdoor unit at 100%
capacity.
b. Charge the outdoor unit as required using the
charging information provided with the outdoor
equipment.
16.2 Electric Heater Kit Testing
1. Select the electric heat icon after entering the air handler
menus in the Cool Cloud HVAC phone application.
2. Select any value less than 50% for low stage operation
and any value greater than 50% for high stage operation.
3. Confirm thermostat heating and cooling calls function
properly with equipment.
17 Quick Start Guide for Non-Communicating Outdoor
Units
EXTREMELY IMPORTANT: For two stage electric heat kit control
the system only needs a single W input. Internal algorithms will
control staging automatically based on the single W input. For
non-communicating outdoor unit wiring, see instructions 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-
communicating heat pump, wire directly to the “O”
terminal on the non-communicating heat pump. See the
following figures.
