3.0 Hello Modes and Automatic Default Program
When the controller is first powered up, the display will show HELLO. In the HELLO mode the
Automatic Default Program (ADP) will run every station every day for 10 minutes. Should you have a power failure and not have a good battery plugged in which would keep the controller’s information and time intact, the ADP program ensures that your landscape will be watered when powered returns.
In the HELLO mode, the ADP will begin the first watering cycle 6 hours after power is reapplied and then continue at 24-hour intervals until the controller is reprogrammed.
Pressing any key will automatically clear the HELLO mode and ADP.
The controller is in the Automatic mode whenever time is displayed and the day of the week indicator is lit.
Pressing QUIT will always return the controller to the Automatic mode.
When a program is watering in the Automatic mode, the program number will be displayed as a convenience.
To stop and cancel a program that is watering.
Press:
CLEAR QUIT
The clock goes back to the Automatic mode.
The controller has a rain switch. The switch must be in the AUTO position any time watering is desired. In the AUTO position, watering will occur if the controller is programmed to do so.
The switch should be placed in the OFF position when no watering is desired, such as when it is raining, etc. In the OFF position, no watering will occur because the switch prevents power from going to the valves.
Rain Master Irrigation Systems 8
3.3 Battery Backup and Power Failures
The controller uses a 9-volt alkaline battery (not included) to keep your program information and time intact during power failures. When power goes out, the display of the controller will go blank to converse battery power. When power returns the display will light up and, after one minute, show the correct time and day.
If HELLO appears in the display, the battery is dead and all program information has been lost.
The controller will run the ADP, as explained in 3.0, until you reprogram it.
Following return of power, should anything other than HELLO or the time and day appear in the display, remove and discard the battery, press the RESET button for approximately 5 seconds, reprogram the controller and install a new battery.
The battery connector is located in back of the lower front panel of the controller.
Battery Type: 9 volt Alkaline “Transistor” such as Eveready #522.
4.0 Basic Programming Examples
Shown below are examples of how to program the controller as well as how to review and clear information.

4.6 Start Times and Automatic Program Overlap Protection
There are four start times available for each of the three programs. They are referred to as
START TIME 1 … START TIME 4.
Additionally, the controller features Automatic Program Overlap Protection (APOP). This ensures that even if start times overlap, only one program will run at a time. Simply stated, any time a program is watering and a start time for a program comes up, the conflicting start time will be delayed until the current program completes its watering.
Rain Master Irrigation Systems 14
For example, if program 1 is one hour long due to the stations and watering lengths placed in it, and you set three of its start times to 7:00 AM, the program will water three times – from 7:00 to
8:00, 8:00 to 9:00, and 9:00 to 10:00 thereby providing two repeat cycles.
Another example, if Program 1 was again one hour long and was set to start at 7:00 AM Mon., and Fri. and Program 3 was set to start at 7:30 AM Mon. and Tue. Then on Mon. Program 3 would begin at 8:00 AM, when Program 1 ended, but on Tue. It would begin at 7:30 AM.
APOP assures you that you will always get the number of watering cycles you desire and at the same time your system will never be under pressurized because two programs are running simultaneously.
4.6.1 Start Time

Rain Master Irrigation Systems 16
To stop and cancel the watering station,
Press:
CLEAR QUIT
The clock goes back to the Automatic mode.
This is used to run only the MV/P for a selected time. The MV/P is a station 1 higher than the number of stations in the controller. For example on a seven station unit, the MV/P would be referred to as station 8. Use MANUAL STATION to run it.
5.4 Manual System Check/Syringe Cycle
This will water each station, from the first to the last, for 1 minute and 45 sec.
Press:
MANUAL
0
Do not press ENTER.
CH will appear in the display indicating check mode. When the last station has watered, the clock will go back to the Automatic mode.
To stop and cancel this cycle,
Press:
CLEAR QUIT
The clock goes back to the Automatic mode.
CAUTION: This mode sequentially runs every station in the controller. For example, you have a
7 station unit but only use 5 stations, it will still apply power to the terminals for station 6 and then to 7 and while doing so will apply to the Master Valve/Pump terminal. This may damage a system using a pump because during the period that stations 6 and 7 are activated, the pump will be pumping against a closed system.
If the system uses a master valve, it will be activated during the period that stations 6 and 7 are active and this could cause heating of the master valve’s solenoid if the valve depends on water flow to cool it. So, if all stations are not used, it is strongly recommended that the user cancel the
System Check/Syringe cycle after the last used station has watered.
Rain Master Irrigation Systems 17

Addendum Instructions for all RMB Series Irrigation Controllers
Document #500027-4 REV. A
This unit functions in the exact same way as our RM series controllers and so you may use the enclosed RM Instruction Booklet for this unit. For convenience, the unit is suitable for outdoor mounting.
Note that the lower row of LED indicators, labeled WATERING STATIONS, is used only to indicate the station watering.
All holes for mounting the unit are provided. Do not drill additional holes in the case. Metal shavings will mix the electronics and damage will result.
To install the controller:
Lay the controller on its back on a flat surface and remove its lower panel. Take the 115/24v transformer and place it in the bottom of the box with its label against the bottom of the controller where the holes are located.
Run the black and white wires through the hole for the transformer located in the bottom of the controller at the right.
Carefully tilt the transformer up such that its threads extend out the hole. Do not let the transformer slide further up into the controller – damage could result.
Thread the ½” C electrical conduit (included) onto the transformer.
Connect each of the two yellow 24v wires to the two left most terminals (labeled 24 VAC) of the terminal strip.
