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.
