HOW THE BACKUP SYSTEM WORKS
The Total Control uses non-volatile memory to store watering programs. This type of
memory prevents the watering program information from becoming lost in the event of
a power failure. An additional benefi t of non-volatile memory is that a factory-installed
backup program is not necessary, thereby avoiding the potential for dead-heading a pump.
Because the current time and date are always changing, only the most recent date can be
saved in non-volatile memory. Therefore, a battery is required to maintain the correct time
and date in the event of a power failure. A 9-volt alkaline battery (provided) will maintain
the correct time and date during power failures up to 90 days. In a typical installation, the
battery should last from two to four years before replacement is necessary. Once the battery
or AC power is connected, the controller can be fully programmed for operation.
NOTE:
For operation of the valves, AC power must be applied.
To install the battery:
1. Pull the two latches on the hinged control
module assembly and carefully swing it outward
to open.
2. Locate and remove the battery compartment
cover from the lower back side of the module.
3. Connect the 9-volt alkaline battery supplied to
the battery clip terminals.
4. Insert the battery into the compartment and
reinstall the battery compartment cover.
Caution: Batteries contain hazardous material. Always handle and discard
batteries properly in accordance with the battery manufacturer's recommendations.
NOTE:
In the event of power failure and the 9-volt battery is missing or drained, only the
time and date will be lost. Controller watering program information will be retained in the
non-volatile memory.
