In the Zone Summary and Setup, you can configure some global parameters, as well as details each zone.

In Zone Configuration:

• Enter the number of zones to configure
  • Note that this will only affect how many zones appear in the Zone Summary and Setup screen; it will not affect the number of zones in the Controller “Thing” page where you can manually toggle zones.  At this time it is not possible to select zones individually which are not in sequential order.
• Increase or decrease all water times by a set percentage
  • Input positive or negative values here to globally adjust all watering times for all zones based on this value.  This adjustment is on top of the seasonal adjustment to watering times.
• Moisture sensor learn mode
  • Learning mode enabled:
    • In learning mode, when it is time to water, Spruce will compare the current moisture value for that zone vs. the moisture sensor target value.  Spruce will use the difference in these values to adjust watering times for the upcoming watering event.
  • Learning mode disabled:
    • When learning mode is disabled, Spruce will use the moisture sensor readings to delay watering. At the next scheduled watering time, Spruce will check the current moisture values and compare it to the Moisture Sensor Target value.  If the current moisture is above the threshold value, Spruce will skip watering for this zone and check again on the next scheduled watering day.   If the current moisture is below the threshold value, Spruce will water as scheduled.

In each individual zone of interest:

• Name your zone
• Sprinkler type:  Select the sprinkler type associated with that zone (Spray, Rotor, Drip, Master Valve, Pump).
  • Setting different sprinkler types will adjust the watering time for each zone based on typical water flow rate differences.
  • A list of eligible sprinkler types are shown below (these are descriptive only, you can’t select from that list)
• Landscape Type:  Select the landscape type associated with that zone (Lawn, Garden, Flowers, Shrubs, Trees, Xeriscape, New Plants).
  • Setting different landscape types will adjust the watering time for each zone based on typical water flow rate differences.
  • A list of eligible landscape types are shown below (these are descriptive only, you can’t select from that list)
• Options (for cycling)
  • In this section you can select options that affect cycling during watering.  See article Irrigation cycles for additional information for why water cycling is important.
  • The Spruce SmartApp provides some cycling presets for sloped landscapes, sandy and clay soil types – select any one of these if they apply to you.
  • The default for cycling is 2x.  It is recommended to cycle a minimum of 2x.
• Select Moisture Sensor to associate a Spruce Sensor with this zone and enable automatic scheduling based on soil moisture data.
  • It is possible to assign a single sensor to multiple zones.  See also, Can I assign the same sensor to multiple zones?
• Minimum Moisture Sensor Target Value: This is the target value for soil moisture immediately before the next watering event.
  • This value does different things, depending on whether the sensor learning mode is enabled in the Water and Moisture Settings.  The default value for this setting will also change depending on the soil type.
    • Learning mode enabled:
      • In learning mode, this is the value that Spruce uses to determine if it watering too much or too little.  At the next scheduled watering time, Spruce will compare the current moisture value for that zone vs. the moisture sensor target value.  Spruce will use the difference in these values to adjust watering times for the upcoming watering event.
    • Learning mode disabled:
      • When learning mode is disabled, Spruce will use the moisture sensor readings to delay watering. This value is essentially a threshold moisture value. At the next scheduled watering time, Spruce will check the current moisture values and compare it vs the Moisture Sensor Target value.  If the current moisture is above the value in this setting, Spruce will skip watering for this zone and check again on the next scheduled watering day.   If the current moisture is below the threshold value, Spruce will water as scheduled.
• Water Time per Week (optional):
  • Leave this field blank if you do not wish to make changes.
  • If you feel that the zone needs more or less water, you can set the week’s total watering duration in this field.  The time represented here is before all adjustments, such as seasonal adjustments or global adjustments in the Water and Moisture Settings.
• Guideline value for dividing Time Per Week into days. A higher value means more water per day.
  • This is a guideline value for your preferred  duration to water each day.  Spruce internally determines a target watering duration for each week, and will use this setting to determine how many days per week to water.  As this value increases, Spruce will generally water longer each day, but fewer days per week.
  • It’s recommended to keep this setting at it’s default value initially, and adjust it later if you want Spruce to water more or less frequently.
  • For example, in the summer, as necessary watering time per week increases, Spruce will factor in this setting and increase the number of watering days per week.  As an example, if Spruce determines that the total watering time needed is 60 minutes, at a default setting of 20 minutes per day, Spruce will water 3 times per week. As the season progresses into winter and total watering decreases, Spruce will decrease the days to water.  As an example, if the total watering time is 20 minutes, Spruce will water 1 time per week.
    • Alternatively if you set the guideline value to 5, the result would be 60/5=12 days.  Let’s say you have only 4 days selected as eligible watering days. Then 60/4 = 12 minutes and Spruce will water on each of the 4 days
