instructions.
• Place the sensor on/off switch to the "on" position to
begin operation (see figure 6)
Rain Sensor Bypass
This sprinkler timer is equipped with a sensor override "on/
off" switch. This switch is for use during maintenance and
repairs, so the sprinkler timer can be operated even if the
rain sensor is in active mode.
Important: If the rain sensor switch is in the "on" position and
no sensor is connected, the sprinkler timer will not operate.

Pump Start & Master Valve
This sprinkler timer allows a master valve or pump start
relay to operate whenever a station is on.
Note: If you are activating a pump from this timer, you must
purchase a Pump Start Relay. From the pump start relay (or
master valve); connect one wire to the "Pump" terminal and the
other wire to the "Common" terminal.
Replacing the Battery
Timer requires a CR2032 Lithium battery
• The battery will maintain your program in case of an AC
power loss
• Battery should last approximately one year
• Open by sliding the battery tray out to the right
• Insert one CR2032 battery into the compartment with
the + side up
• Slide back into place.
PROGRAM
RAIN DELAY
RESET
AUTO
A weak or missing battery can cause the time, date, and
program to be erased after a power failure. If this happens,
you will need to install a fully charged battery and reprogram
the timer.
Tip: Replace battery every year, to avoid loss of programming
Note: A battery alone will not operate the valves in your
sprinkling system. The sprinkler timer has a built-in transformer
that must be connected to an AC line voltage source.
