HOME ENERGY SYSTEM - COMPONENTS
SYSTEM OVERVIEW
All Dave Lennox Signature
®
Collection air conditioners and
heat pumps are equipped at the
factory for upgrading to the
SunSource
®
Home Energy System.
Units can be upgraded at the time of installation or in
the future.
Solar energy is rst used to meet cooling/heating
demands. When the cooling/heating system is not
operating, the system powers lighting, appliances and
other electronic devices in the home. And in some
locations, any surplus power is sent back to the utility
company for a possible credit (check with your local
utility company for availability).
The SolarSync™ Package consists of the following
components:
• Lennox Solar Subpanel eld installed in a Dave
Lennox Signature
®
Collection air conditioner or heat
pump unit.
• Solar Modules (1 to 15 may be used to vary the
amount of electricity generated).
• Envoy Communications Gateway that monitors home
energy usage.
All components must be ordered separately.
Wiring from the roof mounted solar modules is routed to
the outdoor unit. From there power travels to the home
electrical service panel using the existing outdoor unit
power wiring.
NOTE - Refer to separate Product Specications
