Up to 10 mobile devices can simultaneously communicate with an EziSET
®
enabled heater
however only one user at a time can have priority control and alter heater settings. The user
that depresses the
‘HOT WATER’ button first will assume the priority control
and will be able
to adjust temperature settings using the temperature increase (+) / decrease (-) buttons as
shown in figure 2 above. Any additional devices will be able to view the current set point
temperature but will not be able to make any adjustments as the temperature increase /
decrease buttons will not be displayed and the temperature dial will not be illuminated (refer
figure 3).
The mobile device that has priority can give up priority by pressing the
‘HOT WATER’ button
or will automatically lose priority after a default period of 5 minutes of non-use (the non-use
session timeout time can be adjusted from the SETTINGS page if desired). At this point
priority may be
assumed by another device by depressing the ‘HOT WATER’ button.
The ‘Scan’ button appears when the App cannot detect EziSET® on network (refer figure
4).
Press ‘Scan’ to start searching for EziSET on the network again. Once EziSET® is
detected the App will automatically connect and figure 3 will be shown.
The maximum selectable hot water temperature will be limited to 50
o
C. When no hot water
is flowing, temperatures can be selected between 37
o
C and 50
o
C. When hot water is flowing,
the temperature can be increased from 37
o
C to 43
o
C only. The water temperature can be
decreased from any setting whether hot water is flowing or not.
Bath Fill function:
The water volume is measured as the water flows through the water
heater. Therefore if more than one hot tap is open the expected water volume from the first
tap will not be delivered before hot water flow ceases.
NOTE:
The Rheem EziSET
®
App is available from the App or Play Store and is compatible
with a smartphone that has a minimum operating system of iOS 8.1 (iPhone 5, excluding
iPhone 5C) or Android 4.0 and later (Windows phone is not compatible).
Should the home be supplied by 3-phase power, the wireless router and the water heater
MUST be connected to the same phase for EziSET
®
to operate correctly.
