Acclima manufactures both Suspended Cycle™ and Water on Demand controllers (see
Suspended Cycle™ Controller). A Water on Demand Controller applies water immediately
when the soil moisture level falls below the watering threshold - provided it is not
restricted from watering at that time. It does not use Programs. Allowable watering
windows are set up in which the controller can apply water when it is needed.
Watering Threshold
A watering threshold is the soil moisture level at which watering is permitted/allowed. It
is normally the Management Allowable Depletion level or a little above that level.
Watering Program
A watering program (or schedule) is the information store in the controller memory that
determines when an automatic water cycle will occur and how long each zone will water.
The controller requires three basic instructions to operate automatically. A watering
program consists of four data points:
· What days to water—watering days
· What time to water—start time
· How long to water—run time
· Sensor threshold (for sensor programs)
NOTE: Sensor programs may or may not water. They are dependant on soil moisture
levels.
Watering Day
The days of the week selected to water.
Zone
Each solenoid valve controls a specific group of sprinkler heads called a watering zone.
The zones are generally laid out and installed according to the type of plant material to be
watered, such as lawn or flower bed and sprinkler head type. Each valve is connected to
a numbered terminal within the controller, identifying it as Zone 1, Zone 2…Zone 36.
Zone Run Time
The length of time a zone will operate during a watering cycle. Run time can be set from
1 minute to 18 hours.
