Table 8 - Program Data Entry
Operation Description Reference
Step 1 - Enter the
Program Number Select a program number from 1 thru 4. Section 5.1
Step 2 - Enter the Water
Days The days the program will start irrigation. Section 5.2
Step 3 - Runtimes Enter the station length of time. Section 5.3
Step 4 - Start Times Time(s) of the day the program will start. Section 5.4
NOTE: Even though you may have entered the summer reference schedule, once
the RME EAGLE has been setup for ET operation, it will always reduce
the station runtimes accordingly to save water regardless of what time of
year it happens to be.
NOTE: Establishing a spring, fall, or winter schedule can be accomplished in a
similar fashion as depicted above.
8.4 ESTABLISH THE ET REFERENCE VALUE
The ET Reference value is utilized by the RME EAGLE in order to calculate the adjusted station
runtime each time a station is turned on. The calculation compares the ET Reference value with the
daily ET source (i.e. Historical, Internet, or Weather Station). When the source value is less than
the reference value, the RME EAGLE adjusts all station runtimes downward in order to conserve
water.
The ET reference value is directly tied to the ET reference program established in section 8.3
GENERATE THE REFERENCE PROGRAM. If the reference program that you entered into the
RME EAGLE was established for the month of August, then your reference month will be August.
Using RMIS Part Number 500048, Historical ET Data Tables, obtain the ET value associated with
the month of August. Refer to section 7.3 ENTERING THE ET REFERENCE VALUE to enter the
reference value into the controller.
WARNING: Once established, the reference value should not be changed arbitrarily, i.e.
on a daily, weekly, or monthly basis. The reference ET value works hand
in hand with the reference program. The RME EAGLE adjusts station
runtimes by comparing the daily ET versus the ET reference value.
WARNING: If the reference program changes to establish a new program that is
representative of an irrigation schedule for a different time of the year,
THEN the reference value MUST also change.
