Installation Recommendations

WARNING
Improper installation, adjustment, alteration, ser vice or maintenance can
cause property damage, personal injury or loss of life.
Installation and service must be performed by a li censed professional HVAC
installer (or equivalent) or a service agency.
Before beginning installation, note the type of equipment, number of stages,
and any accessories being installed.
Do
• Read this entire document, noting which procedures pertain to your specific
equipment and system requirements.
• Make sure that all wiring conforms to local and national building and electrical
codes and ordinances.
Do Not
• Install on voltages higher than 30VAC.
• Exceed 300 feet (91 meters) run when using 18AWG or 22AWG
thermostat wire or larger (see "Table 5. Terminal Designations and Wiring
Recommendations" on page 6 for further details.
• Allow power load from any thermostat connection to be more than 1 AMP.

Smart Hub Installation

IMPORTANT
Do not install smart hub in location where direct exposure to condensation or
dripping water is possible.
DO NOT install smart hub on indoor unit.
1. Things to consider when installing the smart hub:
• Install near the indoor unit such that there is a direct path to the
approximate location of the home Wi-Fi access point (the signal is not
blocked by the indoor unit or duct work, for example).
• Can be attached to a vertical surface such as a wall stud or roof truss
web, or to a horizontal surface such as a floor or ceiling joist, or a roof
rafter.
• Smart hub antenna should be positioned such that it is roughly vertical,
no matter the orientation of the smart hub, itself.
• DO NOT install the smart hub on the indoor unit, duct work, or other
equipment that could induce vibration in the smart hub.
DO NOT install the smart hub on or near large metal objects. This
•
could adversely affect the range and directional coverage of the smart
hub Wi-Fi signal.
• If the smart hub MUST be installed on a metal object, orientate the
antenna perpendicular to the metal surface.
• In all cases, the smart hub antenna orientation may need to be adjusted
to obtain best Wi-Fi results.
2. Use the following procedure outlined in "Figure 17. Smart Hub Installation"
on page 11.
3. For low voltage wiring connections use diagrams in section titled
"Application Wiring" on page 8.
IMPORTANT
Do not install smart hub in location were direct exposure to condensation or
dripping water is possible.
A Use the Smart Hub as a template to mark the desired mounting locations on the wall or stud.
