INTRODUCTION

ReliaHome Flex is a modular energy management system. It is designed to control residential electric loads to optimize energy consumption. ReliaHome Flex consists of two module types, a Hub Module and a Controller Module.

The Hub Module creates a wireless network within the home to connect up to five Controller Modules, each of which is installed in line with a branch circuit to control an electric load.

IMPORTANT SAFETY INSTRUCTIONS -READ BEFORE USE

WARNING! HAZARDOUS VOLTAGES PRESENT THAT CAN CAUSE ELECTRIC SHOCK, BURNS, OR DEATH. DO NOT HANDLE, INSTALL, USE, OR SERVICE THIS PRODUCT UNTIL YOU HAVE READ THESE INSTRUCTIONS.

WARNING! READ THIS DOCUMENT CAREFULLY AND OBSERVE THE FOLLOWING SAFETY PRECAUTIONS BEFORE INSTALLING OR USING THE SOFTWARE.

Observe the following safety precautions:

●    Installation and servicing must be conducted by a qualified person, according to local and national electrical codes.

●    Certified Installer training must be completed before beginning installation. Only Certified Installers can complete the in-app setup necessary for proper operation. See Step 1 for a link to installation training.

●    Review this entire manual before starting the installation or servicing process.

●    Do not use the product in any way other than its intended use.

●    Do not install or operate the product outside the conditions specified in this manual and product labels.

●    Do not open, attempt to access, or touch any internal product parts except as instructed by this manual. Improper access can introduce damaging static charges to sensitive electronics and will void the warranty. Dangerous voltages could be encountered even when breakers are open.

●    Do not use the product if it is damaged or appears to be damaged.

●    Operate the Hub Module using only the included power supply.

●    For outdoor installation of the Controller Module, utilize suitable approved fittings and preserve weather-proofing integrity.

●    Adhere to all relevant local and national safety regulations for electrical work.

WIRELESS COMMUNICATION

Communication between Flex modules occurs in the 900 MHz band. The network signal created by the Hub Module is not blocked by typical building materials and can travel far enough to reach modules placed at the distant end of a home or even an outbuilding. Communication on this network is not affected by congestion on the home’s general-use WiFi network. Modules are secured through encrypted communication and must be paired through the setup steps listed in this manual.

No access to the home’s WiFi network is required. The hub module is connected directly to the router via an Ethernet cable. 

NETWORK COMMUNICATION

ReliaHome Flex must be connected to the customer’s internet to function. Internet connectivity is required to control the system through the ReliaHome  app when away from the home. Internet access is also required to participate in utility programs.

If the internet connection goes down, Flex will still safely operate but will be unable to accept updates, receive newly scheduled utility programs, or be controlled remotely until the network is restored. Local control is still possible with a mobile device connected to the same Local Area Network (LAN) as the ReliaHome Flex hub.

CONSIDERATIONS BEFORE INSTALLATION

Required for installation:

●    A smartphone or tablet with a camera.

●    Access to the home’s router, as well as the network name and password (for connecting your mobile device).

●    Access to indoor exposed wiring for the circuit desired to be controlled. Edge is not designed to be flush mounted (i.e., set within drywall). 

Installation time varies:

●    The Controller Module may be installed in less than 15 minutes in ideal conditions (e.g., readily accessible Romex cable), while more complex installations may take more than 1 hour (e.g., existing conduit).

●    Setup of the Hub Module and ReliaHome app will take approximately 10 minutes for new systems.

Limitations of Flex:

ReliaHome Flex is able to be installed in homes with backup power but is not designed primarily to limit power usage to stay under inverter capacity. Currently, ReliaHome Flex only integrates with Tesla Powerwall for off-grid battery management. Use the ReliaHome Smart Panel (ABBHEM2) to manage other battery systems.

INSTALLATION PROCEDURE

1.	Become a Certified Installer by taking the required installer training course on the ReliaHome Learnworlds platform. https://reliahome.learnworlds.com/
3.	Ensure that the mobile device being used with the ReliaHome app is connected to the home WiFi network.
4.	Unpack the Hub Module and included cables. Check that all materials are included in the box.	Hub Module Antenna Ethernet Cable Power Cable
5.	Screw the antenna onto the hub controller until finger tight. Do not use excessive force. For best wireless transmission, articulate the hinged antenna so that it is tangential to the location where the controller module will be installed [improve this wording and add a diagram]
6.	Use the supplied wall adapter and Ethernet cable to connect the Hub Module to power and Ethernet. The hub ethernet is normally connected to the home’s wireless router.
7.	Ensure that a whole-home Surge Protective Device (SPD) from ABB's Residential SPD product line is installed. While not required for normal functionality of the ReliaHome Flex system, an SPD protects the energy management system and other sensitive electronics against preventable damage from lightning strikes. Lightning damage is not covered by the ReliaHome Flex product warranty. Note: ABB offers a wide variety of SPDs for every installation, including: THQLSURGE2: Designed for convenient plug-in compatibility with ReliaHome or PowerMark load centers and features 25 kA per phase surge current protection. THQLSURGE5: Designed for convenient plug-in compatibility with ReliaHome or PowerMark load centers and features 0 kA per phase surge current protection. THQLSURGEP5: Designed for convenient plug-on neutral compatibility with ReliaHome load centers and features 50 kA per phase surge current protection. THQLSURGEP7: Designed for convenient plug-on neutral compatibility with ReliaHome load centers and features 75 kA per phase surge current protection. THOMESURGE:  Designed for use with any load center and features 36 kA per phase surge current protection.  SPDs with higher kA ratings offer more protection and higher-value connected equipment warranties for minimal additional cost.	THQLSURGEP7 and THOMESURGE
8.	Unpack the Controller Module and included hardware.
9.	Select a location for Controller Module installation where: ●    Cable/conduit is exposed over a flat mounting surface with enough area for the Controller Module. Alternatively, wiring concealed behind drywall can be routed into the back of the Controller Module, however this significantly complicates the installation. ●    Wire direction (from breaker to load) is apparent. ●    Environmental conditions are within the Controller Module specifications. ●    Cable has sufficient slack and space for routing into the Controller Module. Note that cutting existing wiring and installing the Controller Module adds 4” of slack to the wiring. When installing near the load center, consider installing new cable to the breaker per applicable electrical codes for faster installation.
10.	Write identifying information for the load on the App Setup Card with the matching serial number if the installation location is difficult to access. This will simplify the pairing process.
11.	Identify the load you wish to control and verify it is functional before proceeding. This will help you ensure that the load has been properly deenergized in the next steps.
12.	Locate and turn off the associated breaker for the load to be controlled (or the main breaker if neutrals are shared within the home).
13.	WARNING! Failure to properly de-energize wiring can result in electric shock, burns, or death. Circuit breakers are often mislabeled. Do not proceed until verifying that the wiring to to be cut in Step 14 has been de-energized by means of a voltage tester and ensuring that the load is not functional.
14.	Using the included 1:1 scale Install Template: ●    Cut wiring at the center of the installation location. ●    Trim the cable jacket so that conductors can be arranged individually, but ensure the cable jacked extends through the cable connector and into the Controller Module enclosure. ●    Arrange and trim conductors to fit neatly in the terminals. ●    Strip 0.6” of conductor insulation.
15.	Remove the cover from the Controller Module by loosening the four hex screws on the top of the module using a 4 mm hex wrench.
16.	Determine how the Controller Module will be mounted. There are two options:
16a.	Internal mounting option: Drill mounting screw pilot holes in the four divots located on the interior of the base of the Controller Module. Drilling these holes will violate the raintight integrity of the enclosure and should only be done for indoor or sheltered installations.
16b.	External mounting option: Use the provided mounting tab screws to secure the four external mounting tabs to the screw bosses on the bottom of the Controller Module.
17.	Use a step bit or hole saw with pilot bit to drill holes in the Controller module enclosure for cable connectors or conduit connectors. There are two options:
17a.	Rear-entry option: Use a step bit or hole saw to drill two holes centered on the two small divots on the back of the Controller Module. Holes must be the correct size for the cable connector or conduit connector you will use. After drilling, gently shake or blow out any plastic drill shavings inside the Controller Module.
17b.	Side-entry option: Use a step bit or hole saw to drill two holes centered on the two small divots on either of the short sides of the Controller Module. Holes must be the correct size for the cable connector or conduit connector you will use. After drilling, gently shake or blow out any plastic drill shavings inside the Controller Module.
18.	Install listed cable or conduit connectors in the Controller Module.
19.	Determine the correct orientation of the Controller Module in the installation location: ●    The wire terminals labeled Line In is in the direction of the load center with the associated breaker. ●    The wire terminals labeled Load Out is in the direction of the controlled load.
20.	Mount the Controller Module to the wall using the pilot holes drilled previously and wood screws or concrete anchors (not included).
21.	Referencing the included 1:1 Scale Install Template, route the wiring into the Controller Module through the cable clamps and secure all conductors in the wire terminals using a 4 mm hex wrench. Ensure the wires are connected to the correct terminals labeled: L2     [Line 2] (240 V circuits only) N      [Neutral] L1     [Line 1] GND [Equipment Grounding Conductor] Conductor selections must be identical for input and output. For example, if a black wire is connected to L1 of the Line In terminal, a black wire must connect to L1 of the Line Out terminal.
22.	Torque wire terminals as follows:  4-8 AWG:      45 inch-pounds 10-14 AWG:  35 inch-pounds
23.	Tighten the cable connectors to secure the connected cable (if applicable). The combination of cable and fitting must entirely cover openings to prevent contact with hazardous voltages after installation.
24.	Ensure that the wiring or conduit is properly secured to the wall on both the line and load sides of the Controller Module. Typically non-metallic cabling must be secured within 12 inches of enclosure entry and electro-metallic conduit (EMT) must be secured within three feet, but check local code requirements.
25.	Install the cover back on the Controller Module. Use the previously removed screws to secure the cover. Note that the cover can be secured in either orientation that matches the body of the controller module. Users may find it more intuitive if the power light is the top-most or left-most of the indicator lights.
26.	Turn on the associated breaker.
27.	Confirm that the blue power indicator light is illuminated through the cover of the Controller Module. If no indicators are lit, wiring may have been reversed: ensure that the conductors from the load breaker have been installed on the "Line In" terminals.
28.	Proceed immediately to the Mobile App Configuration steps below. The controlled load will not function until the system has been properly configured in the app.

MOBILE APP CONFIGURATION

29.	Download the ReliaHome mobile application. Note: Do not download the ReliaHome Solar+ app. The correct app contains the letter “e” in the depiction of a house in the app icon.
30.	Open the ReliaHome app and select Create Account or Login (if an account has already been created). Ensure that the email address used for the account is the same one used for Certified Installer Training. If this is your first ReliaHome (or Lumin) installation, follow the link in the account activation email you receive.
