Q - Do these devices work around corner of a building? What if there is a wall or some trees and shrubs? Or it has to be line of sight?
A - The devices will operate even if they are NOT in line of sight. The distance would highly be dependent on what is between the transmitter and receiver. A stucco wall (with the "chicken wire" in it) or steel framed building would reduce the range quickly, every wall would reduce the range by about 100 yards based on what we have experimented, but it won't kill it. A wooden wall or some trees and shrubs would have almost no effect.
Q - How can we extend the range?
A - We used a Yagi antenna for the receiver and manged to get close to 3 miles of range. The Yago antenna was placed about 16 feet above ground. We can customized the box for an external antenna and ship the antenna and box to you with needed hardware to mount them.
Q - Do you do custom solutions if we need modification?
A - Yes, we can.
Q - Can these devices be places under ground in a valve box and not have them exposed?
A - Yes, we can place them under a lid with a thick polycarbonate plexiglass and a custom antenna and will ship the completed unit to you.
Q - Do I need to have direct sun light all the time on receiver?
A - No, but they do need sun light. For WB-100 and WB-124 we recommend an hour of sun light for every 30 minutes of operation. For WB-200 we recommend 1 hour of sun light daily.
Q - Is there a battery inside the receiver?
A - Yes, the battery runs the valve and it would be trickle charged by the solar panel. Solar panel is NOT running the valve.
Q - How long the batteries are good for?
A - They are rated for 10 years of operation and do not to be changed, only charged with Sun. After 10 years the batteries will be at 70% of their original condition, so even after 10 years they are NOT dead and useless. There is no need to change the battery.
Q - Are the batteries available in the market?
A - Yes, they are sold in many outlets online and in stores. But, they do not need to be replaced.
Q - How long is the warranty on each device?
A - Three years. Return them within the first year and we either refund your money or replace it, no question asked. After the first year, we will repair or replace the unit for up to two additional years if they fail to operate.
Q - Do I need to buy different controller for WB-200 vs. WB-100 (or WB-124)?
A - No. All of our devices work with any standard 24V controller. So, all of the DC valves (aka Nodes or hockey-pucks) and standard 24V valves can be controlled with the one controller.
