MASTER VALVE C O M M O N T O A L L V A L V E S Remove the lower cover of the DDC controller. Place the unit on the wall using the top screw slot. Level the controller, then insert screws into the two lower screws holes under the terminal block. Connect the solenoid wires to the terminal block. Connect one wire from the solenoid to its respective station number on the terminal block and the other wire to the C-common terminal. Finally, connect the transformer wires to the 24 VAC terminal. 9 VDC battery. The 9 volt battery compartment is located between the sensor terminal and the 24VAC terminal. The 9 volt battery powers the LCD display in the absence of AC power and allows “Arm Chair Programming “. Program information is retained during power outages by an on-board lithium battery. Note: Only after all the wiring is completed and checked should the transformer be plugged into AC power. -3- Sensor connection and operation: TRANSFORMER Quick Ref. Card RESET SENSOR Install in a protected area. 9 volt Battery SENSOR To connect a rain sensor, remove the jumper wire from the sensor terminal and connect one wire of the Toro Rain Switch to the C-common terminal and the other wire to the N.C. (normally closed) terminal. As soon as the Rain Switch contacts change from the N.C. position to the N.O. (normally open) position, irrigation will be suspended. Irrigation will resume as soon as the Rain Switch dries and its contacts return to the N.C. position. When irrigation is suspended due to the Rain Switch, the display shows: OFF NOTE: When using the Toro Rain Switch, follow the Basic Connection Installation Instructions. -4- Block Diagram presentation of the programming sequence of the 3 irrigation parameters: Run Time, Days and Starts for each program.
