compartment is sealed with four (4) screws.
2. Unscrew all screws and remove the battery
compartment lid using a Phillips screw driver.
3. Install one 9-volt battery (not included).
Observe the polarity of the picture.
4. Reattach the lid and screws, ensuring the
rubber sealing gasket is in place.
e battery should be replaced as part of
yearly maintenance. e controller will
maintain time/day/program for 32 minutes
without a battery installed.

is not necessary. Follow the directions below to attach the SST to your valve:
1. Turn water o to the valve.
2. Unscrew the existing solenoid
and discard.
3. Screw in the included adapter
(if necessary) (Figure 1).
4. Screw the Toro solenoid onto
the adapter (Figure 1).
5. Mount the SST onto the
