How to connect rain sensor to sprinkler timer that does not have rain sensor terminals

For Timers without Rain sensor terminals
Illustration shows how to connect Rain-Click (or any brand rain sensor) to a timer that does not have rain sensor connections.
Rain click is simple on-off switch
Wires on rain click are rated 24 volt AC
Yellow wires from timer carry 24 volt AC

Relay is ON when no rain..
Relay OFF when it has rained, so pump cannot activate when timer turns on

14 day skipper wheel

14-day skipper wheel

Intermatic sprinkler timers are 14-day timers
Set watering times, and then skip any day of week
Each day of watering follows same schedule, but selected days can be skipped.

Install 107T19 silver pin into the timer dial at 12 midnight location so skipper wheel advances each day.
107T73 Day wheel pins are located around the skipper wheel and pulled upward to select which days will be skipped.
How to set and troubleshoot sprinkler timer

Sprinkler timer dial

Notice silver-colored skipper-wheel advance pin located at 12 midnight position on dial.

Push trippers all the way down on the timer wheel
Each tripper represents 15 minutes. Two trippers in a row make 30 minutes. Four trippers in a row make 60 minutes of watering.
Leave tripper out of the dial, and sprinkler head will advance to next zone. Next tripper on dial will start watering at the next zone.

Stationary pinter remains at 7:00 o'clock position.
Set current time by rotating dial until current time lines up with stationary pointer.
