PC-104/106 SPRINKLER SYSTEM CONTROLLER INSTALLATION INSTRUCTIONS Rain Bird Rain Clocks are designed for use with all standard residential 24 volt AC electric valves regardless of brand. However, some older brass electric valves and commercial duty plastic valves may have power requirements higher than this series is designed for STEP 1: MOUNT THE TIMER Location: Select a location inside a building, and within six feet of a grounded electrical outlet. This is not an outdoor timer.
STEP 2: CONNECTING THE WIRING How to choose the right type of sprinkler wire: Use 18-gauge “bell,” “thermostat” or “underground burial” wire for the sprinkling system. “Bell wire” is available in single strands or twisted in 2 or 3 wire sets and can only be used indoors. “Thermostat wire,” the most common sprinkling system wire, is typically available with up to 7 wires twisted inside a brown PVC jacket (about ¼” in diameter), and is suitable for most indoor and conduit installations.
STEP 3: CONNECTING THE TRANSFORMER Refer to Figure 2 and connect the yellow wire to the terminal marked "YELLOW," and red wire to the terminal marked "RED" and the blue wire to the terminal marked "BLUE." Caution: Always connect the wires before plugging in the transformer. If not, you run a risk of short circuiting the transformer and/or clock. STEP 4: USING THE PUMP START CIRCUIT Pump start or master valve capability is available only on the PC-106-PS and PC-104-PS models.
PROGRAMMING INSTRUCTIONS Use to set the days to water Use to set the daily start times Use to set current time Adjust time up and days to on Use to set length of watering SET CLOCK WATER DAYS STATION TIMING MANUAL START & WATER TIMES PER DAY AUTO ADVANCE ON Adjust time down and days to off OFF OFF Use to operate system manually Use to put timer in rain shut down mode STEP 1: SET THE CURRENT TIME AND DAY SET CLOCK The PC-104/106 Series holds a 7 day program which repeats after the seventh
1-D: To display the Current Time Press Display Shows: SET CLOCK The above setting of 2:20 PM = 1420 military time You can also press the “SET CLOCK” button during any other programming operation to return it to the time of day display. STEP 2: SET THE DAYS OF THE WEEK TO WATER When shipped from the factory, the PC-104/106 Series is pre-set to water every day of the week. Since this is a single program timer, all stations will water on the same program of watering days.
2-B: Watering on an “Interval” of Days (i.e. every 3rd day) Now Press Adjust Day 1 to “ON” with: WATER DAYS Display changes to: ON Now Press Adjust Day 2 to “OFF” by pressing: Display changes to: OFF WATER DAYS Now Press Adjust Day 3 to “OFF” by pressing: Display changes to: OFF WATER DAYS Now Press Then adjust Day 4 to “- -” by pressing and holding Display changes to: OFF WATER DAYS for 3 seconds.
STEP 3: SET THE TIME OF DAY TO WATER This button determines the time of day when the cycle will start watering. The timer can be set to water once, twice, or three times per day. All stations will start in sequence at each start time (for example, if this is a four station timer, and the start times are set at 8:00 AM, 1:00 PM, and 6:00 PM, all four stations will go on sequentially at 8:00 AM, 1:00 PM, and 6:00 PM). Start #1 is preset at 8:00. Starts #2 and #3 are blank unless programmed.
STEP 4: SET THE WATERING TIME FOR EACH STATION This button sets how long each station (zone) will run. Each station can be separately adjusted between 0-99 minutes in one minute increments. This “watering time” is always the same for that station, every time the system waters. The PC-106/106 series is preset to water each station for ten minutes.
STEP 6: TO INTERRUPT WATERING FOR RAIN The “AUTO/OFF” button allows the watering and programming to be interrupted until pressed again. it does not affect the program, but it does prevent power from going to the valves. Press Display will show: The Current Time AUTO OFF Last Digit Blinks i.e. the current time is 8:00 a.m. Press “AUTO/OFF” again to return to normal. TROUBLE-SHOOTING Sometimes when problems occur they can be easily solved by rechecking some often overlooked possibilities.
Programming limitations of this timer The PC-104/106 series are very flexible timers available at a very economical price. However, there are some things it will not do: -It will not run more than one valve per station (i.e. two valves can't be connected to one terminal/station); -It will not run some stations on one set of days and some stations on another set of days. This feature is called dual programmability. -It will not run stations on separate start times.
What should be done in the winter? If you live in an area where you don't use the timer for an extended period of time, we recommend unplugging and possibly storing the timer. The "Auto/Off " rain shutdown mode is a short-term shutdown only, not a winterization mode. In addition, if you're in a freezing area, be sure your sprinkler lines don't have any water left in them. NOTE: This Rain Clock Timer generates radio frequency energy and may cause interference to radio and television reception.
