Controllers are the brains of a sprinkler system. They activate and deactivate designated irrigation zone valves according to programmed run times. Properly programmed controllers ensure a landscape is receiving the right amount of water at the optimal watering time.
Programs are used to divide up areas in your landscape that have different watering needs.
A Start Time is the designated time of day when a Program will begin watering. More information
It is a section of an irrigation system served by a single control valve. Stations are also commonly referred to as valves, circuits, or zones. They are made up of plant material that has similar water requirements.
A run time is the amount of time entered into the controller for a station. More information
Water Days are the days you input into the controller to tell it what days of the week you want it to water. More information
Seasonal Adjustment is used to make global run time changes without the need to reprogram every station's run time. More information
The goal of the run time calculator is to use information you provide to calculate a peak season, or "hottest month" schedule that you can enter into your controller. More information
A basic understanding of your landscape, and your irrigation system is all you need to get started with the application. More information
A complete watering schedule (Program) includes the following:
1. Watering Start Time(s)
2. Station Run Time(s)
3. Water Days More information
The Hunter Run Time Calculator will provide you with a programming schedule for the hottest month of the year in your area. Once you have that schedule in your controller check the seasonal adjustment percentage for your area in the calculator. More information
Rain is not used in the calculation of your schedule, so if you live in an area that receives precipitation during the irrigation season you should make sure your system has at the very least a rain shut off device attached to the controller. More information
The Hunter Run Time Calculator uses your location to determine the amount of water your landscape may need based on the hottest time of year. More information
There are three different Plant Types for you to select from in this section: Turfgrass, Trees/Shrubs/Mixed, and Other. Inside each of these categories are more specific selections. More information
This factor is subjective, but the guidelines shown by each of the 3 options should help you to make an educated guess. More information
The guidelines shown on each of the 4 options should help you to make a decision about which to choose. More information
This is another subjective factor, so make a reasonable guess on the most common condition for the area in question. More information
Soil type is best determined in a lab, but we've simplified the number of types down to 5. Use the description by each type to help you come up with a likely type. More information
This is another subjective factor, so make a reasonable guess based on the descriptions given for the different slope percentages. More information
There are three different Sprinkler Types for you to select from in this section: Sprays, Rotors, and Multi-Stream Rotors. If you choose a vegetation type other than turf, you will get a fourth option: PLD/Drip More information
There are a wide variety of drip emitters on the market, as well as bubbler-type sprinklers, and micro-spray sprinklers. There are so many variables involved with these products, and their installation that it is extremely difficult to calculate generalized run times for them. It is best to consult with your local irrigation professional to determine what type of product you have, and how best to set an accurate schedule.
These two controllers were not specifically included in this version of the calculator, but we do intend to add them in the future. More information
The Hunter Run Time Calculator uses your location to determine the amount of water your landscape may need based on the hottest time of year.
When you are on the Programming Guide page, you can select edit next to the station number to go back and make changes to the information you entered.
Select Edit Controller on the programming guide to go back to the controller information. You will then be able to add more stations.
We ask you when you would like to start watering before we build your schedule. You may have reasons for wanting to water early in the morning, or you may want the sprinklers running when you are awake and can see them. More information
One of the first things you are asked when you begin the process of setting up your schedule is if you have watering restrictions in your area. More information
You may already be watering at levels needed for your landscape. More information
Yes and No. Your free account allows you to setup as many controllers as you want. However, watering restriction options are tied to each account and each account is tied to a unique email. So, if you are a professional with customers who have different watering restrictions, you need to create an account with a unique email for each area you are dealing with.
We suggest setting up a gmail account for the areas needed. A short video tutorial is here http://youtu.be/cfO_iRv9Jro
No, the Run Time Calculator is really meant to be used for ornamental landscape plantings. Vegetable gardens have different watering needs, so it is best to rely on other sources for information on how to properly water them.
The Run Time Calculator asks you to place different types of plant material in different programs because each general type of plant material can have different watering requirements. Having separate programs for the different types of plants allows you to have better control over the watering schedule, and more readily meet each plant's needs. More information
Currently, there is one way to rename your controller. More information
Seasonal Adjust, also known by municipalities as Water Index, is used to make global run time changes without reprogramming the entire controller and is perfect for making small changes that are necessary as the weather changes throughout the year.
Please keep in mind that these run times are based on your area's hottest month. You will need to adjust water usage as temperatures cool and heat up. You can either do this manually, through your seasonal adjustment feature on your controller (select models only) or through a weather sensor, such as the Solar Sync.
Climate data for
For instance, during hotter times of the year, the landscape may require a bit more water. Seasonal Adjust can be increased so the stations run longer than the programmed time. Conversely, as fall approaches the Seasonal Adjust can be reduced to allow for short watering durations. This overall percentage based change applies globally to all Run Times on the controller. For example: If your Run Times in the summer are set for 1 hour and you adjust the Seasonal Adjust to 50%, your Run Times will now change to 30 minutes.
