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.

When you change any of the following parameters, the
new values will only display on the web user interface.
