There are overlapping start times programmed. Clear all start times and then enter only one start time. If you would like to water more than once a day, enter the next start time for later in the day. A start time is the initial time of day when the timer will begin to water. Each station or zone will then water in sequence according to its chosen duration. Multiple start times allow you to water all stations more than once in the same watering day.

Programming instructions are included with each timer. These instructions are available for each timer in the Product Manual section. Browse the online catalog to find your timer or use the search at the top of every page! Orbit also offers an online tutorial and video on how to program your timer in the Video and Tutorial Support Sections.

One or more of the electric control valves has a shorted solenoid, or there is a short in the wiring. If you have a multimeter or volt meter you can check your wiring and solenoids for shorts and continuity. Otherwise, try switching another solenoid from a functioning valve to see if the problem valve will turn on. If so, replace the solenoid. If not, you may have to replace the wiring.

Check the transformer for output (24VAC). Push the red power reset button or verify that the fuse is good. Turn on a station manually and check the output at that station (24 VAC). If there is proper voltage, there may be a problem with the wiring or the solenoid on that valve. If the valve has a flow control, be sure it is open all the way. If there is low or no voltage, the timer needs to be replaced.

There is an error in programming. Reset the timer and then reprogram.

This is generally a wiring problem between the timer and the valves. To be sure, check the output at the timer and verify that there is voltage only at the station that the display indicates is watering. If so, then electrical current from one valve is transferring to the wires on the other valve causing them both to open. Replace the wiring to the valves.

The battery compartment is located on the back left side if you are looking at the face of the timer. If you feel along the left side of the timer you will feel an indentation and see a little slit that a screwdriver can be put in to slide the tray out to the left. Or you can take the timer off of the wall and turn it over and you will see the square tray that slides out.

No. These timers do not offer the pump start terminal or master valve functionality.
