I discovered this by accident and its really causing grief with my schedules. Especially since I have this type of logic on almost everything in my house.
I have 2 irrigation schedules both at 6pm. The one who's conditions are met should be running, but they are BOTH running.
This should be satisfied for temps 100-101-102-103-104-105-106-107-108-109 [as they are between 99 and 110]
This should be satisfied for temps 110-111-112... [as they are greater than 109]
Why are they both being satisfied?
