CoNNECTING a HUNTEr solar syNC ET sENsor
region
For accurate Solar Sync measurements, the controller needs to
be programmed for the average peak season ET for your region.
Use the table below to determine your region.
The table will assist you in identifying the type of region you live
in. There are four basic ET regions, each with descriptions of the
region, along with typical ET and temperature characteristics. It is
recommended that, if possible, the region be chosen based upon
average July ET or peak summer ET (inches/mm per day).
Use the following table for choosing your region (reference below).
You can use methods A, B or C to help you choose which region is
best for your area:
A: Based upon the ET of your region using the average July ET
or peak summer ET (inches/mm per day). This is the preferred
option when selecting your region.
B: Based upon the temperature for your region using the average
July or the driest month high temperature (not the highest
temperature for July).
C: Based upon the general description of your region.
• U.S. Northern States
• Coastal Regions If the average July ET is
< 0.17" (4.3 mm) per day
If the average temperature for July is
65°– 75° (18°C – 24°C)
If the average temperature for July is
75° – 85° (24°C – 29°C)
• Mountains
• U.S. Northern Inland States If the average July ET is 0.18" – 0.23"
(4.6 mm – 5.8 mm) per day
• U.S. Southern States
• Inland/High Desert If the average July ET is 0.24" – 0.29"
(6.1 mm – 7.4 mm) per day
If the average temperature for July is
85° – 95° (29°C – 35°C)
• Deserts If the average July ET is > 0.30"
(7.6 mm) per day
If the average temperature for July is
95° – 105° (35°C – 41°C)
* For Southern hemisphere locations, use the month of January.
