Operation on 208 Volt Supply
The unit transformer is factory connected for 230 V operation. If
unit is to operate on 208 V, disconnect the red wire from terminal
3 of the unit transformer and connect them to terminal 2 of the
unit transformer.
24 Volt Thermostat Wiring
NOTE:
Removable connectors are provided with the control
to make thermostat wire connections. The connectors may be
removed, wire connections made and the connector replaced. It is
STRONGLY
recommended that you do not connect multiple wires
into a single terminal. Wire nuts are recommended to ensure one
wire is used for each terminal. Typical 18 AWG thermostat wire may
be used to wire the system components. 150 feet is the maximum
recommended length of wire recommended between indoor and
outdoor unit, or between indoor unit and thermostat.
NOTE:
Wire routing must not interfere with the circulator blower
operation or routine maintenance.

NOTE
: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equip
-
ment generates, uses and can radiate radio frequency energy and,
if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
—Consult the dealer or an experienced radio/ TV technician
for help.
Actual screens may look different based on the mobile device
being used.

This air handler is Bluetooth ready and functions with the Cool
Cloud HVAC phone application designed to improve the
contractor’s setup / diagnostic experience. Users can see specific
model information, review active diagnostic error codes, observe
system menu testing of all operational modes (heat / cool / fan)
directly from the phone. The phone application is also capable of
directly updating the air handler software anytime updates are
available. The application will automatically notify the user.
NOTE:
The software update may take up to 20 minutes to
complete.
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.
