phone, tablet, or computer over your home’s wireless
(WiFi) network.
• Receive alerts when you’re low on hot water.
• Create custom water heating schedules that are
controlled by your computer or other device through
your home’s WiFi network.

2Review the requirements.
To get started, you will need:
• A working wireless (WiFi) network router with Internet
access.
• A personal computer, smart phone, or tablet computer
connected to your home’s WiFi network.
• One of the following water heater models:
ES2H40HD045V, ES2J40HD045V, ES2H50HD045V,
ES2J50HD045V, ES2J65HD045V, ES2H80HD045V,
ES2J80HD045V, ES40R92-45D, ES40R123-45D,
ES50R92-45D, ES50R123-45D, ES80H123-45D.
• One #2 Phillips screwdriver.
Read and follow all of the instructions, cautions, and
warnings in your water heater’s use and care guide.
WARNING! Even if the water heater’s temperature
control is set to a relatively low temperature, hot
water can scald. Install thermostatic mixing valves at
each point-of-use to reduce the risk of scalding.
3Install the Controller.
WARNING! Working on an energized circuit can result
in severe injury or death from electrical shock. Turn power
off before performing this installation. Check wires with a
non-contact circuit tester to make sure power is off.

4Complete Setup.
Step 1: Check the Status LED on the controller.
The Status LED should brighten gradually, then
dim suddenly. If it does not brighten gradually
and dim suddenly, press the reset button 8
times with a paper clip (about once per second)
until you hear a beep. See Figure 1. The beep
indicates that the controller has been reset.
Step 2: Open a wireless network control panel on your
device (computer, smart phone or tablet).
A list of available wireless networks should be
displayed (Figure 4).
Step 3: Disconnect your device (computer, smart
phone or tablet) from your home’s WiFi
network.
You will connect to a different network during the
next step.
Example: List of SSIDs Displayed in
Available Wireless Networks

Step 5: Once your computer is connected to the
energySmart network,
A. Open a browser window.
B. Type 192.168.10.1 into the browser’s Ad-
dress or Location bar, then press [Enter].
See Figure 6.

B. IMPORTANT: If your router is set to hide
its SSID, look for its MAC address instead.
You will be asked to enter its SSID during
the next step.
C. Click the “Join” button next to your home’s
wireless network (Figure 7).
D. If necessary, type your wireless network
password in the dialog box, then click OK.
E. When you have connected successfully, the
Status LED will be on steady (no blinking,
flashing, or dimming). However, if you don’t
get a steady LED status light, repeat all
steps in this section.
Step 7: Reconnect your device (computer, smart
phone or tablet) to your home’s wireless
network.
Step 8: Register and sign in as described in the next
step.

Status LED
The green LED on top of the controller indicates its
connection status or error state as described below. See
Figure 8.
See Troubleshooting for an explanation of each flash
code (page 8).
Beeper
Audible beeps indicate status changes that require your
attention. If you hear a beep, refer to the Troubleshooting
section to determine its meaning.
Reset Button
The reset button is located toward the center of the
electric water heater controller (Figure 1).
To reset the controller and put it in Access Point (AP)
Mode:
1. Press the reset button 8 times with a paper clip
(about once per second) until you hear a beep. See
Figure 8.
The beep means that the controller has been
disconnected from the WiFi network and has been
reset.
2. If you can’t connect to an SSID in the available
networks list, repeat step 1. (See Figures 5 & 7).
This may be necessary in areas with multiple WiFi
signals or when the WiFi signal strength is weak.
To restart the controller without going into Access Point
(AP) Mode:
1. Press and hold the reset button down until you hear a
beep (about 12 seconds).
2. Release the button. The controller will reconnect
to the web server. However, it will not default to AP
Mode.

Enabled / Disabled
Enabled
To control your water heater through Iris®, your controller
must be enabled and connected. It is enabled when the
Grid Enabled button is lit up (backlit). See Figure 9.
To enable the controller:
1. Unlock the water heater’s user interface (if it is
locked). To do so, touch the lock button for at least
5 seconds. The Lock icon will disappear from the
screen.
2. Touch the Grid Enabled button until it lights up
(backlit).
Disabled
While disabled, all water heater parameters can be
viewed through Iris®, but they can only be changed
through the water heater’s user interface. This safety
feature can be used to ensure local control only.
The controller is disabled if:
• The Grid Enabled button is not lit up (not backlit)
• The controller’s LED is flashing “3 seconds ON, 3
seconds OFF.”
IMPORTANT: In the event of a power outage, the Grid
Enabled Button will turn OFF automatically. See Figure 9.
Enable it as described in Enabled above.
To disable the controller so that the water heater can only
be controlled locally:
1. Unlock the water heater’s user interface (if it is
locked). To do so, touch the lock button for at least
5 seconds. The Lock icon will disappear from the
screen.
2. Touch the Grid Enabled button until its light goes out
(no longer back lit).
Parameters
You can monitor and control the following water heater
parameters through Iris®: operating mode, temperature
set point (up to Maximum Set Point), and heating
schedule. Estimated Hot Water Level may be viewed
through Iris®.
For safety reasons, your temperature setting through Iris®
cannot exceed the temperature that is programmed into
your water heater’s user interface.
For example, if the user interface on the water heater is
set at 120°F, the set point range in Iris®would be 80°F to
120°F. 120°F would be the Maximum Set Point.
WARNING! Even if the water heater’s temperature
control is set to a relatively low temperature, hot
water can scald. Install thermostatic mixing valves at
each point-of-use to reduce the risk of scalding.
Read and follow all of the instructions, cautions, and
warnings in your water heater’s use and care guide.
Parameter List
When you change any of the following parameters, the
new values will only display on the web user interface.
The remote settings will not be displayed on the water
heater’s user interface, but this will not effect your
intended settings.
Mode
Standard, Energy Smart and Schedule
Set Point
Temperature setting range: 80°F to 150°F (27°C to 65°C).
NOTE: Your temperature setting through Iris®cannot
exceed the temperature that is programmed into the water
heater’s user interface.
Heating Schedule
This parameter allows you to set water heating schedules
through Iris®.
Estimated Hot Water Level
The estimated hot water level may be viewed through Iris®.
This parameter is not configurable.

TROUBLESHOOTING
Frequently Asked Questions
Q. The power to my house went out. When it came
back on, I couldn’t control my water heater
through Iris®. What’s wrong?
A. In the event of a power outage, the Grid Enabled
Button will turn OFF automatically. When it does,
the controller is disabled and your water heater
cannot be controlled through Iris®. To restore
functionality, follow the instructions in the Enabled
section, page 6.
Q. I’m trying to increase the water temperature
setting though Iris®. It doesn’t work. Why won’t
it work?
A. For safety reasons, your temperature setting
through Iris®cannot exceed the temperature that
is programmed into your water heater’s user
interface. For example, if your water heater itself is
set to 110°F, then 110°F is the highest temperature
setting allowed in Iris®. Check your water heater’s
temperature setting and adjust as necessary.
Q. One of the parameters shown in Iris®is different
than what is displayed on the water heater’s
user interface. Is this okay?
A. Yes. The controlling parameters are displayed in
Iris®. See Parameters on page 6.
