HARDIE RAINJET RJC-66 (01) PDF Document

The following are definitions for the various modes and settings on your controller:

Manual – Used to initiate unscheduled watering. Will continue to water until turned off by the user.

Auto – Will initiate the programmed schedule when the program switch is in RUN mode.

Rain/Off – Interrupts the watering schedule without interfering with the set program.

Set Time – Used to program the current time of day.

Program A – Used for programming or initiating the primary watering schedule.

Program C – Used for programming or initiating the secondary watering schedule.

Run – Will operate programs when the mode switch is set to AUTO.

Run Time 1-6 – Amount of watering time in minutes for the indicated station.

Select-A-Day – Used to program watering at specific intervals (every third day, etc.).

Set Today – Used to program the current day of the week.

Sun 1-Sat 7 – Used to program watering on specific days of the week.

Time 1-3 – Time(s) of day that the watering cycle is to begin.

+ / – – Increase or decrease the displayed number.

Your HARDIE RAINJET RJC-66 controller is designed to allow two independent watering schedules for different parts of your yard.

Your primary watering schedule (for lawns, etc.) should be set on Program A. Areas of your yard that require a different frequency of watering (like shrubs, vegetable gardens, or hillsides) can be scheduled on Program C.

For example, you could program your lawn valves 1 and 2 (Run Time 1 and Run Time 2) to water every day on Program A. Then, you could set valves 3 and 4 (Run Time 3 and Run Time 4) to water only on Monday and Thursday on Program C.

Valves scheduled for Program C should display “00” on Program A. Valves scheduled on Program A should display “00” on Program C. Usually, a valve is only scheduled to run on one program.

Follow these steps to install your controller:

1. Mount the Controller

Install the controller near a 117VAC outlet, preferably in a weather-protected area. Drive the provided screw into a wall stud, leaving about 1/4″ of the screw exposed. Hang the controller from the keyhole slot located in the back of the case. For further security, you can add an additional screw to the bottom of the case where indicated.

2. Connect the Valves

CAUTION: Never connect the valves while the transformer is plugged in.

Route one wire from each valve through the hole at the left bottom of the case. Insert this wire under a numbered screw and tighten. The ground wire from each valve should be attached to a single “common” wire. Route this common wire through the same hole as the valve wires and connect it to the screw marked “COM.”

NOTE: This controller is for use with 24VAC, 5VA solenoid operated valves. A maximum of two valves per station and no more than three valves (or solenoids) should be on at any one time. This includes the master valve, if used. Current requirements should not exceed .32 Amp for each solenoid.

3. Connect the Transformer

CAUTION: Do not plug in the transformer until after the transformer leads are connected.

Route the two transformer leads through the small hole at the right bottom of the case. Insert one lead under each screw marked with a “T” and tighten the screws. Now, plug in the transformer. In areas where power surges occur, install a surge protector between the transformer and outlet (supplied by the user).

4. Connect the Backup Battery (Optional)

Using a nine-volt alkaline battery (supplied by the user), connect it to the battery terminal. In case of a power outage, this battery will provide backup power to retain the program and advance the clock. The battery does not contain enough power to operate the valves. A typical alkaline battery contains enough power for 6 to 12 hours of power loss.

NOTE: The circuitry for a master valve or pump is optional and found only on the -1 model.

To use a master valve, connect one solenoid lead wire to the terminal screw marked “M” and the remaining lead to the terminal screw marked “C.” The master valve must be equipped with a 24VAC, 5VA solenoid.

If a pump is to be used, connect a relay lead to the same terminal used for the master valve connection. The pump relay should have a nominal coil voltage of 24VAC at .25A maximum.

CAUTION: If you are using a pump start circuit, the “fail safe” program will activate the pump for each of the six stations for 10 minutes each. If you are using fewer than six stations, the pump will run against a “dead head” on each unused station, which can cause a burn-out of the pump. To avoid this, connect a jumper wire from the unused station terminal over to a station terminal that is being used.

Before you begin programming watering schedules, set the current time and day:

1. Set the MODE switch to AUTO.

2. Set the program switch to PROGRAM A/SET TIME.

3. Push + or – until the current time of day appears. NOTE: This controller is based on military time (Hours 1-12 are a.m.; hours 13-24 are p.m.).

4. While pressing SET TODAY, press + or – to indicate the current numerical day of the week in the display (SUN = 1, MON = 2, etc.).

The controller is now set to the current time and day.

Be sure the program switch is set to either Program A or C. This controller has two types of watering cycles: specific days of the week or specific intervals.

To Water on Specific Days of the Week:

1. Press SELECT-A-DAY and press either + or – at the same time to indicate “OFF” in the display.

2. While pressing each day of the week button in turn (e.g., SUN 1, MON 2), press either + or – to indicate on the display which days are to water. The display will read “ON” when watering will occur and “OFF” when watering is not needed.

To Water at Specific Intervals (e.g., Every Third Day):

1. Select SELECT-A-DAY to “ON.”

2. Determine the interval you wish watering to occur. For example, to water every third day, press TUE 3 and the + or – until “ON” is indicated in the display. The number under the day of the week indicates the interval.

3. Now press all remaining days (numbers) so they display “OFF.” Only the desired interval number should display “ON” when pressed.

This controller can start up to three times for each program during the same day.

1. While pressing START TIME 1, depress + or – until the time of day you wish to water appears in the display.

2. Repeat this procedure for START TIME 2 and 3. If you do not need three start times, set START TIME 2 and 3 to “OFF” (Not 0:00, which represents midnight.)

This is called “run time.” The HARDIE RAINJET RJC-66 has six watering zones or “stations.” Each zone can water from one minute to 99 minutes per start time. Set all stations not being used to “00.”

1. While pressing RUN TIME 1, depress + or – until the desired watering time is displayed.

2. Repeat for each station.

Return the PROGRAM switch to RUN and you’re done!

If you’re using both programs (A and C), repeat the programming steps for those stations on Program C. Usually, you will have a valve operate on only one of the programs.
