3.3 Control switch
The control switch of the controller turns the water heater ON and OFF. Note that in the
OFF position the water heater remains electrically live, in order for the continuous pump
to stay running.
After switching on, the text INTERNAL CHECK appears on the display for about 10
seconds. The main menu (see section 4.3) then appears. If no selection is made in the
main menu, the water heater automatically switches to the OFF mode (see section 3.6.1).
Note
To electrically isolate the water heater, you must use the isolator between the water
heater and the mains power supply.
3.4 Buttons
The use of these buttons is explained with the help of the figure showing the main menu
(see section 4.3).
The buttons are:
Buttons for UP [ ], and DOWN [ ];
Enter: [ENTER];
Reset button: [RESET].
The arrows and indicate that you can scroll up and/or down. Use [ ] and [ ] to
scroll.
The cursor ® points to the option to be activated. In the display as shown in the figure,
you can scroll through the main menu.
The main menu comprises: OFF, ON, WEEK PROGRAM, EXTRA PERIOD and
SETTINGS. You have to scroll down further to see the options EXTRA PERIOD and
SETTINGS.
The selected option is confirmed using [ENTER].
Pressing [RESET] takes you back one page in a menu and discards all options selected in
the current menu.
Note
[RESET] is also used to reset the water heater following an error.
3.5 PC connection
The PC connection is exclusively intended to enable technicians from A.O. Smith to read
the status and history of the water heater. These details can be important for
troubleshooting and/or resolving complaints.
