Weather Reach Receiver Operating FAQ's



Do I need to connect my Weather Reach Receiver to a computer to make settings changes?

No. You do not need to connect your Weather Reach Receiver to a computer to make settings changes; it can simply be done directly within the Weather Reach Receiver. Please see Chapter 4, General Operation, page 12 in the Users Guide.


What happens if I need to turn the sprinklers off for a day?

Set the sprinkler controller to not allow watering on the unavailable day. The Receiver will suspend watering until the next available watering day.


Is there a manual override for testing valves or spot watering?

Yes. Press the Manual Override button on your Weather Reach Receiver and this will allow you to manually turn on your sprinklers for an hour. To get additional time press the manual override again, each time the button is pushed an hour of override is added.


How will my Weather Reach Receiver work with a remote control?

Your sprinkler controller remote will not control your Weather Reach Receiver. If you change settings in your sprinkler controller with your remote, the Weather Reach Receiver will need to be adjusted to the changes.


How would the Weather Reach Receiver work with my pump start?

If using the ET Enable output these instructions need to be followed: If the pump is started from the controller using a pump start circuit it typically uses the same valve common that goes through the WR-7. The WR-7 will keep the pump off just as it keeps the valves from operating. But, when both the A and B common is used an isolation relay needs to be installed. Contact Irrisoft for more details.


Why does the Crop Coefficient change?

The Weather Reach Signal Provider broadcasts a Crop Coefficient value and it may change through the year. The Crop Coefficient is used to adjust ET to more accurately represent regional conditions, and regional weather conditions change as seasons change.


How vulnerable is the Weather Reach Receiver to power bumps, and lightning?

All electronic devices are vulnerable to power bumps and lightning. The WR-7 Weather Reach Receiver has built-in surge protection. For protection to work the WR-7 must be properly grounded.


What happens if the power goes out, will it loose any settings?

The WR-7 Weather Reach Receiver has non-volatile memory. If power is lost it will resume where it was. The time of day will be updated the next time a signal is received.


How can I use Weather Reach when I don't have enough time to water my site in a single night of watering?

Use "A then B mode" which limits only one of the ET Enable circuits from watering in the same night. Valves connected to common A circuit would water through one ET Time Window cycle and the next night the valves connected to common B circuit would water. Please see Chapter 5, ET Enable, page 41 in the Users Guide for more details, link.


Will my Weather Reach Receiver turn on my sprinklers in the middle of the day?

Your Weather Reach Receiver only allows watering to happen. The sprinkler controller is programmed with start times.


How do Weather Reach Receivers deal with excessive rain?

Rainfall amount and intensities can vary widely. A heavy, hard pounding down pour may be prone to run-off, whereas a gentle rain will soak into the ground. Heavy accumulations may soak well below the roots, and would no longer be available to the plants. To restrict the amount of rain recognized by the system two effective rainfall limits can be programmed.

1. Maximum Hourly Rain - Rain that falls faster than the soil can absorb may become run-off and may not be available to the plants. Enter the maximum amount of rain that should be accepted each hour in the ET balance.

2. Extra Rain A (or B) - Heavy rainfall may percolate below the root zone making it unavailable to the plants. Enter the number of inches of extra rain that the soil can hold beyond the ET Threshold. The value could be approximately 50% of the ET Threshold. This value controls the maximum amount of extra rain allowed in the ET balance. As rainfall amounts accumulate the ET Balance can go below zero and become a negative number. This setting creates a negative limit to the ET Balance. A Soil Holding setting of .25 would limit the ET Balance to negative .25.


Will the Weather Reach Receiver reduce run-off?

Run-off occurs when sprinklers apply water that cannot be absorbed by the soil. The Weather Reach Receiver will only allow watering after soil moisture has been depleted. Because the soil is not saturated the water can soak in. Sprinklers may apply water faster than the soil can absorb. If the application rate cannot be reduced then the water can be applied in multiple cycles. The sprinkler controller should be programmed with the number of start times needed to manage the run-off. The Weather Reach Receiver will allow all cycles to run to satisfy the watering requirement
