PERATION
The battery backup will last over 2 years of “powered-off time”. This means that if the Smart Touch is plugged into a control that
is powered up, the battery is not being drained. Only when the AC power to the control board is powered off is the battery being
drained in the Smart Touch itself.
When the battery dies, is removed, or replaced, the only information that is lost is the date and time. No other information is lost.
Also the screen lock PIN will be reset to its default (“1234”) when the battery gets removed or dies. This is done in case the
locking PIN is forgotten and the display gets locked. All other programming parameters, calibrations, program scheduler
settings, etc., are retained in flash memory forever, and do not use the battery power at all.
When the battery dies, there will be no visible indication on the display during normal power up. What will happen is that upon a
subsequent (AC) power down and power up, the user will immediately be prompted to set the date/time setting. This is their
indication that the battery needs replacement. Note that if the battery were dead and the date/time were set correctly during a
given AC power up, as long as the display has AC power, it would retain the correct date/time indefinitely. The next time AC
power is removed, the date/time would again be lost and be prompted for upon the next AC power up. When the fresh battery
gets installed, the next AC power up will also immediately prompt for the date/time setting.
