6. Setting the second timer
The second timer is an added feature that can only be set between the hours of 21:00 – 08:00. Note
that the timer will only work in standard mode. Before setting the timer, ensure the clock is adjusted to
the right time. Note that the timer start time is set first, followed by the end time. If users choose not to
activate the timer function, press the 'Program' button repeatedly till the 'Timer 1' and 'Timer 2'
indicator lights are off.
The directions for setting the second timer are the same as setting the first timer. The difference is that
while setting the second timer, ensure that the indicator light showing 'Timer 2' is lit before you press
and hold the 'Program' button to enter the setting mode.
To view the timer settings, press the 'Program' button repeatedly to select either Timer 1 or Timer 2.
Press and hold down the 'Program' button for 3 seconds. The time that appears is the start time. Press
the 'Program' button again to show the end time. Press the 'Program' button again to exit the menu.
7. Heating modes
The 'Heating Mode' button allows users to switch between three heating modes, 'standard', 'single'
and 'multiple'. By default, the system is set to 'standard' mode. Users may only select one heating
mode at a time.
Standard mode: The system runs to conserve energy and the instant and MAX functions are not
available.
Single mode: The system heats only half a tank and is good for very low-usage periods and the
instant and MAX functions are not available.
Multiple mode: The system runs at high performance to meet the needs of larger, high-usage families.
8. MAX function
The MAX function is an A. O. Smith technology that allows users to get consistent hot water for long
periods of time. This function will automatically activate if there is an unexpected surge in demand
for hot water. The ►► indicator will light up when MAX is activated.
The MAX function will not work in 'standard' mode.
