Sprinkler head advances to next station each time Insert 156T1950A trippers on outer edge of yellow dial. Each tripper represents 15 minutes/ Set minimum 12 minutes- max 20 hours 45 minutes Insert four consecutive trippers for 1 hour of watering time. When 1 hour is over, then timer no longer sends 24Volts to sprinkler head, and sprinkler automatically advances to next watering station. When timer dial rotates around to the next tripper, water resumes at next watering station. Silver Pointer located on timer dial is stationary. To set current time, rotate dial until current time lines up with silver pointer. 14-day skipper wheel |

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

rain sensorLarger image Here is finished project using a rain sensor to override timer. Image shows the Dayton power relay inside a square rain-proof PVC enclosure (junction box). Small relays (or power relays etc) are rated 15 amp but have working maximum of 10 amp. Note, the sprinkler timer enclosure usually does not have enough extra space to add the relay pointer. 14-day skipper wheel Buy 1EJG9 relay Hubbell bell junction boxes 2-gang junction box 1/2" Flexible conduit For safety, all boxes must have a cover. |

| Wiring Tips | |
 |
Keep wires straight Use solid copper, 600 volt wire (voltage printed on insulation sheathing of each wire. Never use extension cord for permanent residential or commercial wiring. Avoid stranded wire. All wire expands and contracts as power is turned on-off. Heat causes stranded wire to splay apart and get loose, eventually arcing and melting the terminal. Do not use solder on electrical connections. Solder melts with heat as power is turned on-off. If wiring terminals are corroded, try using a toothbrush and vinegar. If wiring terminals are rusted, try using WD-40 and/or fingernail sanding board. If wiring terminals are burned, try using bit of sandpaper or sanding board. If wiring terminals are melted, then timer is probably bad ... it is risky to connect wire to a damaged electrical device ... Keep timer door closed to prevent fire ... the closed door starves a fire from oxygen and extinguishes flame. |
