Remove the lower cover. Place the unit on the wall using the top screw slot. Level the controller, then insert screw into the lower screw hole 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. Connect the transformer wires to the 24 VAC terminal. Note: A 9 VDC battery must be installed for proper operation of the controller. The 9 volt battery compartment is located on the right side of the case. It is marked “Push”. Push it to release the battery drawer. 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.

INSTALLATION INSTRUCTIONS - OUTDOOR MODELS:
Remove the lower cover of the Junior Max controller by sliding it down. Place the unit on the wall using the top keyhole screw slot. Level the controller and then insert screws into one or more of the three lower screws holes at the cabinet bottom. Drive the screws through the plastic flashing that keep the cabinet weather resistant. If installing the controller on drywall or masonry, install screw anchors to prevent the screws from loosening. Connect the solenoid wires to the terminal block through the 12mm (1/2”) hole in the right side of the cabinet bottom. If the solenoid wires are being installed in conduit, there is a knock-out on this hole that will accept a 24mm (1”) male conduit adapter. Connect the wires as shown for the indoor model. Next connect the power wires.
Warning: AC power wiring must be installed and connected by qualified
personnel only. All electrical components and installation procedures must comply with all local and national electrical codes. Some codes may require a means of disconnection from the AC power source installed in the fixed wiring and having a contact separation of at least 3mm (0.120”) in the line and neutral poles.
Make sure the power is OFF prior to connecting the controller.
The hole on the left side of the cabinet bottom accepts a 12mm (1/2”) male conduit adapter. Route the power and equipment ground wires from the power source, through the conduit and into the transformer connector compartment. Note: The terminal block accepts wire size up to 4mm2 (12 AWG). Remove 10mm (3/8”) of insulation from the wire ends. Using a small flat bladed screwdriver, secure the wires as follows: Line or Line 1 (L1) to L, Neutral or Line 2 (L2) to N and Equipment Ground to G. Install compartment cover. Apply power to the controller.
9 VDC Battery. The 9 volt battery compartment is located below the 24VAC terminals. The 9 volt battery powers the LCD display in the absence of AC power and allows programming without AC power. Program information is retained during power outages by an on-board lithium battery.

To connect a rain sensor, remove the jumper wire from the sensor terminal and connect one wire of the Irritrol Rain Sensor to the C-common terminal and the other wire to the N.C. (normally closed) terminal. As soon as the Rain Sensor 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 Sensor dries and its contacts return to the N.C. position.
When irrigation is suspended due to the Rain Switch, the display shows: OFF

The “%” icon will also be displayed whenever that program is operating or being reviewed to alert you that the run time has been adjusted from the initial setting.
To set a program to "OFF"
If you wish to stop irrigation of a program, set percentage scaling to 0%. The display will show that program is OFF. To resume normal operation of that program, advance to "% SCALING" and increase the percentage to your desired value. Increasing to 100% will set RUN TIME to its original value.

Program C – Looping Program
Program C runs as a regular program if only one start time is used. Entering a second and third start time changes program C to a looping program. The controller recognizes this and displays “LOOP” in the LCD display. A looping program allows the station assigned to program C to be run repeatedly throughout a 24 hour period. A loop program is desirable for seed germination, asexual propagation, misting and cooling. Sensors such as thermostats, humidity sensors, etc., can be incorporated into the looping program.
NOTE: Important Differences
1. If only one start time is entered, the controller considers Program C as a regular program and run times are set and displayed in hours and minutes.
2. When a second start time is entered, the controller recognizes that program C is being set as a looping program. Run times are now set and displayed as minutes and seconds. The second and third start times are still set and displayed in hours and minutes. As an example, the third start time is the loop delay. You want a delay of 120 minutes. The display will show 2:00 or two hours.
3. Loop delay includes the station Run Times
4. Loop delay default time is 5 minutes
Example: You are germinating a seed lawn and wish to irrigate every half-hour between 7:00 AM and 6:00 PM. Station run time is 2 minutes.
Run Time = 2:00 = 2 minutes “Start 1” = 7:00 AM = Time the loop will start “Start 2” = 6:00 PM = Time the loop will stop “Start 3” = 0:30 = 30 minute loop delay
