TEST ALL STATIONS The Pro EX 2.0 allows the user a quick and simple method for checking all available stations by running a test program. This feature operates each station individually in numerical order starting with the lowest available station. Station operation is preset for a two minute run time which the user can alter at anytime during the test. NOTE: Changing the test run time can be done at anytime and for any station during the test.
SPECIAL FEATURES SEASONAL ADJUST STATION DELAY/OVERLAP PUMP ON / OFF The seasonal adjust feature allows the user to increase or decrease station run times globally, for all stations, without re-programming each individual station. Run times can be reduced to as little as 10% or as high as 200%. The station delay / overlap feature allows the user to insert a global time delay or overlap between the end of any station’s watering cycle and the beginning of the next station’s watering cycle.
SENSOR OPEN CIRCUIT DETECTION CLEAR The SENSOR on/off feature allows the user to enable or disable the SENSOR terminals for each individual station. The open circuit detection feature prevents pump and station operation when the controller detects an open circuit. The on/off feature is used in irrigation systems where it is desirable for a Rain Sensor to operate or not operate for a specific station(s).
SPECIAL FEATURES SAVE RESTORE DISPLAY CONTRAST The SAVE feature allows the user to save all current programing. This allows the user to quickly and easily restore any saved program(s) should they be changed. The “RESTORE” feature allows the user to restore any previously saved programs.

Then press the NEXT button until FLOWMTR is displayed. Push NEXT to select. flow mtr 5.
SET OPTIONAL HI/LO FLOW LIMITS Using the Hi/Lo flow limits feature allows you to fine tune your flow sensing. Setting these limits helps in diagnosing or pinpointing where you may have a water management issue, a line break, a broken head or even a clogged line, for example. You can either keep them very general and set the limits by program or be very specific and set the limits by individual zone. 2. Press the NEXT or BACK button until SET MTR is displayed.
SPECIAL FEATURES SETTING BY PROGRAM 1. Push NEXT to select BY PROGRAM. by prgm 2.
