The Enphase Environ Smart Thermostat
The Enphase Environ™ is the world’s first solar-integrated, web-enabled,
smart thermostat. Using plug-and-play wireless technology, the Environ
connects to the Envoy Communications Gateway, and is integrated with the
Enlighten™ website. This allows you to monitor and control your heating and
cooling at the wall, on the web or from your smart phone.
The Environ Smart Thermostat is compatible with all popular residential
HVAC systems:
x
24VAC single, two, three stage conventional heating systems
(gas/oil/electric)
x
heat pumps (single and two stage compression)
x
single or two stage auxiliary heat (electric or fossil)
x
zoned forced air and zoned hot water (2 or 3 wire) (Enphase Energy
recommends professional HVAC installation for zoned forced-air
systems due to additional equipment for baffles, etc.)
x
millivolt systems (with 24VAC adapter)
x
one or two stage cooling
x
hybrid systems.
The Enphase Environ™ will control temperature to an accuracy of ± 1° F and
is designed to work with ambient temperatures from 35° F to 95° F
Heating or cooling temperatures can easily be set on the large touchscreen
with the
+/-
buttons. A minimum 4 minute off time protects heating and
cooling compressors from damage. This thermostat uses a new technique
called sequential staging for more comfort with faster reaction to requested
temperature changes.
This thermostat must be run on the HVAC system’s 24VAC (C wire) or
external 24VAC transformer connected to the C and RH terminals. The 24VAC
C wire is located on the other side of the 24VAC heating transformer, and
can be found where the other thermostat wires connect at the wall or at the
furnace.
Other Elements in the Enphase System
The
Enphase Enlighten
web-based monitoring and analysis system
analyzes the per-module data collected by each microinverter. Enlighten
automatically detects any shortfall in energy production, identifies possible
causes, and suggests solutions to correct the problem. The Enphase
Enlighten website is constantly monitoring every module on every
installation.
The Enphase Envoy communications gateway and the Enlighten Energy
Monitoring capability have been expanded to support additional smart energy
