(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.

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.
