Programming Before Installation; Installing The Battery - Toro GreenKeeper 212 User Manual

Programming Before Installation

The GreenKeeper 212 utilizes a 9-volt battery to retain its
watering program information in the event of a main power
interruption. This battery backup feature also enables
your controller to be fully programmed for operation right
out of the box—before installation—in the comfort of your
home. Simply attach the battery and begin the program-
ming steps. The program information will be retained for
the duration of the battery life – about 72 hours for an
Alkaline battery or 24 hours for a rechargeable Nickel-
Metal Hydride (Ni-MH) battery.

Installing the Battery

Note: The 9-volt battery does not supply enough voltage
to operate the station control valves.
1. Indoor models: Slide the lower housing cover toward
the bottom of the controller to remove.
Outdoor models: Pull outward on the lower housing
cover handle to remove.

2. The display will begin flashing 12:00
+/ button to stop the display from flashing. The
ON
colon (:) will continuously flash while displaying the
time and during watering operation. The Power Off
symbol will be displayed until the main power
supply is connected.
3. Locate the battery charger
switch (9) as indicated in
Figure 2. If an Alkaline bat-
tery is installed, the switch
must be set to the left posi-
tion (ALK) to turn the
charging circuit off. If a
rechargeable Ni-MH battery
is used, the switch must be
set to the right position
(RCHG) to turn the charging circuit on.
Caution: The battery charger switch must be set
correctly. Damage to the controller can result from
an Alkaline battery which may fail if charged.
4. Reinstall the lower housing cover.
Always replace battery with the same or equivalent
type. Dispose of used batteries according to the
battery manufacturer's recommendations.
