IntroductionWelcome to Intelligent Watering!Timer FeaturesThank you for purchasing a WiFi-enabled Smart Timer fromRain Bird, a trusted name in irrigation throughout the worldfor over 80 years.The Timer has a variety of advanced watermanagement features, including: Zone based programming allows independentirrigation scheduling for different areas (Zones), basedon the specific water requirements for each area.In this manual are step by step instructions for how toinstall and operate your timer. P rograms can be set to water on selected days ofthe week, odd or even calendar days, or at customintervals, allowing enhanced flexibility and control ofirrigation schedules. M ultiple Watering Start Times allow you to run thesame program multiple times on the same day.Timer manual interface controlsand indicators. S easonal Adjust allows quick adjustment of wateringduration based on weather or other conditions.The manual timer interface allows for visualconfirmation of schedule as well as customprogramming when a mobile device is not available.

InstallationMount TimerTools and Supplies NeededMount the Timer in an accessible location Phillips screwdriverNOTE: Indoor models are for indoor useonly. Outdoor models can be used indoorsor outdoors. Wire stripper HammerNOTE: For indoor models, choose a locationwithin 6 feet of an AC power outlet and atleast 15 feet away from major appliances orair conditioners. V alve wire: direct burial, color coded multistrand (not included) 18 gauge for runs less than 800 feet.Drive a screw into the wall, leaving an 1/8” gapbetween the screw-head and the wall (use thesupplied wall anchors if necessary). 14 gauge for runs greater than 800 feet. Watertight splice connectors (not included)Locate the keyhole slot on back of the unit andhang it securely on the screw.Before Removing Old TimerRemove the wiring bay cover at the bottom ofthe unit and drive a second screw through thecenter hole at the bottom of the unit as shown(use the supplied wall anchors if necessary).ABAT&TAT&T4:24:211PPMM100%24VACSENSOR COM12345INDOOR MODEL6100%1/8 IN.A.

Optional AccessoriesPump Start RelayConnect an optional Master Valve, Pump StartRelay or Rain Sensor to the Timer.Pumps are used in some places to draw water from awell or other source. If you are activating a pump fromthe Timer, you must install a pump start relay.Master ValveA pump start relay connects to the Timer in the sameway as a Master Valve, but connects differently at thewater source.Timers support the use of a master valve.Using a direct burial cable, connect one of thewires from the master valve (or pump start relay)to the master valve terminal (M).To avoid possible pump damage, connecta short jumper wire from any unused zoneterminal(s) to the nearest zone terminal in use.Connect the remaining wire from the mastervalve (or pump start relay) to the commonterminal (C).Example: If a 4 zone model Timer is in use withonly two zones connected, route the terminalsfor zones 3 and 4 to the nearest active terminal(in this example, zone 2).RESET24VACSENSC M 12345678A CCESSORYACTIVETERMINALRESET24VACA PERWIRES4SENSC M 12345678

Outdoor TimerThe outdoor controller comes with a standard 6 ftpower cord so it can be installed indoors, or outdoorsif plugged into a weatherproof external outlet.The outdoor controller can also be wired directly intoa power supply by removing the power cord. It has aninternal transformer that reduces supply voltage (120VAC in US) to 24 VAC. You will need to connect powersupply wires to the transformer’s three wires. (Line,Neutral, Ground).CONNECT120 VACWIRING COMPARTMENTRoute the three wires from an external powersource into the wiring compartment.WARNING: Electric shock can cause severeinjury or death. Make sure power supply isturned OFF before connecting power wires.Using wire nuts, connect the external powerwires to the internal connection wires inside thewiring compartment.WARNING: All electrical connections andwiring runs must comply with local buildingcodes.WARNING: Be sure to connect the coloredcoded external wires to the same color internalconnection wires, as follows:WARNING: DO NOT apply power to the unituntil you have completed and checked all wiringconnections.WARNING: Disconnect or shut off theexternal power source before connecting ordisconnecting wires to the ve the wiring bay cover at the bottom ofthe unit.Remove the WIFI Module to access the wiringcompartment.Locate the wiring compartment in the lower lefthand corner of the unit and using a screwdriver,unscrew wiring compartment front cover.EXTERNALPOWER WIRESUnscrew the wire nuts connecting the powercord and the transformer wires.
