1) Begin the Enlighten activation
process, specifying the number of
Environs at your site.
2) Install the Envoy before installing
the Environ Smart Thermostat. See
the Envoy Quick Install Guide for more
information.
3) The Envoy may automatically
upgrade in order to support Environ.
Do not interrupt power during this
upgrade.
CAUTION:
To avoid electrical shock and to prevent damage to the furnace, air conditioner, and
thermostat, you should disconnect the power supply before beginning work. You can
disconnect the power at the circuit breaker or at the HVAC system.

ou must have a "C" wire or other 24VAC power available at the Environ location. If a "C"
wire is not present, you must add this wire. See the Environ Installation and Operation
Manual for more information.
For 'multi-zone' systems where multiple thermostats are connected to a single HVAC
system, Enphase Energy recommends professional HVAC installation ONLY.
Make sure your wires are labeled. This may require you to find the far end connection for
each wire on your heating or air conditioning equipment and read the label there. Refer to
the Wire Reference in the Environ Installation and Operation Manual for more information
about wire labels from different HVAC system manufacturers.
IMPORTANT:
"C" wire or 24VAC power is required
for the Environ to operate. If you do
not have a "C" wire, you can run a new
wire from the HVAC to the Environ or provide
24VAC power to operate the Environ using a
standard 24VAC wall transformer.
IMPORTANT: If you have both RH and RC wires, remove the metal jumper-clip
between these 2 terminals.
IMPORTANT: If you have both O and B wires, consult the Environ Installation
and Operation Manual for wiring information.
