P & R CONTROLLERS

All controllers have cast aluminum housings.
The housing contains a microprocessor, a motor, rechargeable battery and solar panel.
The program automatically sets timed intervals to turn the butterfly valve.
The controllers are energy self-sufficient.

All models feature ONE NUMBER EASY SETTING

• Enter one number to automatically set a program that figures how many cycles and how long each will run to get water across the field most efficiently and uniformly.
• The program automatically shortens cycle times for soaking without runoff once the water has advanced across the field.
• The number set can be changed mid-watering and will automatically correct all cycles to fine tune the program.
• Simple Off/On restarts the program held in memory.

The PRO JR II Controller

Features rotary switches to select automatic advance settings and to adjust automatic soak cycles to avoid runoff red flashing diode to indicate program is running manual "change side" toggle switch for directing water See How to Operate the Pro Jr. II for details

The STAR Controller

Features simple, single function keys for setting a constant read out display English or Spanish key for readout in display manual "change side" key for directing water setting for different percentage of water going left and right constant display of total running time and time until next change display of all cycle times in program on demand timer for startup or mid-watering pause battery voltage readout adjustable setting for side change speed from 1 to 60 seconds automatic fertigation See Star Operating Instructions for easy, quick startup

Fertigation

The Star controller has built-in software and connectors to control an external fertilizer injection pump. P & R also offers a Surge Fertigation Pump System. The Star is programmable to set the volume of fertilizer to be injected through a P & R surge valve. The controller displays the minimum time it will take to complete the desired application, and signals the pump to dose the fertilizer in short time increments during the soak cycles of the irrigation. See Star Fertigation Instructions for details.

P & R VALVES

P & R has five valve sizes including 4", 6", 8", 10" and 12". All controllers can be used on any size P & R valve. The valves are T shaped, cast aluminum diverters which take water in on one port and deliver it left or right to the other two ports. The butterfly valve is activated by a motor in the controller. All valves have a male port at the entry and female ports at the two exits.
