2The 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:

x24VAC single, two, three stage conventional heating systems

(gas/oil/electric)

xheat pumps (single and two stage compression)

xsingle or two stage auxiliary heat (electric or fossil)

xzoned 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.)

xmillivolt systems (with 24VAC adapter)

xone or two stage cooling

xhybrid 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

7 Copyright Enphase Energy Inc. 2010 141-00010 Rev 01

devices and services such as the Environ Smart Thermostat. This capability

enables Enphase Systems to not only generate clean energy, but also to

monitor and control energy usage.

Through Enlighten, you can manage your Environ Smart Thermostat from

anywhere through the Enphase Enlighten web-based portal. Enlighten

enables you to view and edit your programs and settings. It provides:

xease of use of setting configurations and setting up 7-day programs

through a large web browser window rather than on the wall-mounted

unit.

xthe ability to access these settings online from any browser, as well as

smartphones.

xvisibility to solar production information and HVAC controls side-by-side

on the same portal.

The Enphase Envoy is an integral component of the Enphase Energy

Microinverter system. It operates between the Enphase Environ,

microinverters, and the Enphase Enlighten web-based monitoring and

analysis system. The Envoy functions as a gateway and monitors the

microinverters that are connected to the photovoltaic modules.

The Enphase Microinverter is a fully integrated device that converts the DC

output of a single solar module into grid-compliant AC power. In addition to

performing the DC to AC conversion, it maximizes the modules' energy

production by using a sophisticated Maximum Power Point Tracking (MPPT)

algorithm.

How the Environ Smart Thermostat Works with the Enphase System

The Environ programmable communicating thermostat interfaces to the

Enphase Envoy communications gateway using a ZigBee wireless interface.

This interface is designed to be plug and play.

Once mated, the Environ can be reached and programmed through the

Enlighten website from virtually any location.

3Environ Installation

Your thermostat is a precise instrument; please handle it

with care.

Turn off electricity to the HVAC system before installing or

servicing the thermostat or any part of the system. Power

can be disconnected at the circuit breaker or at the HVAC

system.

Do not turn electricity back on until work is completed.

Do not short (jumper) across electric terminals at the

control on the furnace or air conditioner to test the

system. This may damage the thermostat.

All wiring must conform to local codes and ordinances.

This thermostat is designed for use with 24VAC and millivolt systems with a

separate 24VAC power adapter.

The thermostat relay load should be limited to 1.0 amp.

Higher amperage may cause damage to the thermostat.

You will need a small Phillips screwdriver and a drill with

3/16-in. (4.8mm) bit for wall mounts.

Location

Replacement installations: mount the

Environ in place of the thermostat. You

must have a C wire or other 24VAC

power available at the Environ location. A

new location will require moving your

wiring.

For new installations and for re-locating

the Environ, follow these guidelines:

xLocate the thermostat on an inside

wall, about 5 ft. (1.5m) above the

floor, and in a room that is frequently used.

xDo not install it where there are unusual heating conditions, such as:

in direct sunlight; near a lamp, radio, television, radiator register,

fireplace; near hot water pipes in a wall; or near a stove on the other

side of a wall.

9 Copyright Enphase Energy Inc. 2010 141-00010 Rev 01

xDo not locate in unusual cooling conditions, such as: on a wall

separating an unheated room; or in a draft from a stairwell, door, or

window.

xDo not locate in a damp area. This can lead to corrosion that will

shorten thermostat life.

xDo not locate where air circulation is poor, such as: in a corner, an

alcove; behind an open door.

xDo not install the Environ until all construction and painting has been

completed.

Note: The thermostat does not require leveling.

Remove the Old Unit

Read the instructions carefully before removing any

wiring from the existing thermostat. Wires must be

labeled before they are removed. THERE IS NO

STANDARD COLOR CODE. When removing wires from

their terminals, ignore the color of the wires and LABEL

THEM by the terminal where they were screwed.

Switch OFF electricity to the furnace and air conditioner,

then follow these steps.

1. Remove the cover from old thermostat. Most are snap-on types and

simply pull off. Some have locking screws on the side or front. These

must be loosened. DO NOT remove wires. Note the letters printed near

the terminals. Attach labels (enclosed) to each wire for identification.

2. Label the wires one at a time. You must label all the wires before you

proceed. With all wires labeled,

remove them from the old unit.

3. Make sure the wires do not fall back

inside the wall. You can wind them

around a pencil to keep them from

falling.

4. Loosen all screws on the old

thermostat and remove it from the

wall.

10 Copyright Enphase Energy Inc. 2010 141-00010 Rev 01

What wires do you have?

Make sure your wires are labeled. This may require you to find the other end

connection for each wire on your heating or air conditioning equipment and

read the label there. Refer to the Wire Reference on page 39 for better

understanding of wire labels from different HVAC system makers.

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, remove the

metal jumper-clip between these 2 terminals.

IMPORTANT:If you have both O and B, refer to page

39 for wiring information.

Prepare Wires

Please follow these guidelines for safe and secure wire connections:

xYou will need at least 2.6” (66 mm) of wire for each of your

connections to the Environ.

xIf you do not have enough wire, splice additional wire to allow enough

slack.

xFan out wires below the hole as shown.

xRemove insulation 1/8” (3 mm) from the tip of each wire.

xTake care not to damage the labels for each wire in handling.

Do not allow wires to touch each other or parts

on the thermostat.
