My new Orbit WiFi 12 zone controller works great. One thing I have not been able to test is my existing Rainbird RSD rain sensor. It had been working fine with my Rainbird controller.
I’m curious if anyone has the Rainbird wired RSD sensor working with the Orbit b-hyve WiFi controller.
The past 2 weeks I have used the weather delay feature and it works. But then it rains and I don’t know if the physical rain sensor would have also triggered a delay. I don’t have a hose that can reach where the sensor is located to manually test it and it is high on my roof.
I will try turning off the weather delay and see if the sensor by itself creates a delay. We may get some rain this weekend.Spread the love!June 22, 2018 at 10:26 pm #3871
As luck would have it I was able to get a hose over to that side of the house today. I sprayed the sensor with a deluge of water for a good 10 minutes. The Orbit controller did not show a rain sensor delay on the controller screen or on the iPhone application. And I do have the sensor turned on in the controller.
Any idea on how to get this to work or will I need to buy an Orbit rain sensor so it is compatible?Spread the love!June 26, 2018 at 8:04 pm #3977StevenParticipant
RandallFosler, Orbit timers are set up to work with rain sensors that operate as a normally closed circuit, and then send a rain delay signal when there is a break in the circuit. I cannot say how your current sensor operates, but it will need to be a normally closed operation to be compatible. If it is a two-wire sensor then it needs to be hooked up in series with your common wire, not to the rain sensor terminals which are used for wireless rain sensors.Spread the love!June 26, 2018 at 8:51 pm #3984
Steven – thank you. I bet that is my problem. My Rainbird sensor is a wired (2 wire) sensor that is normally closed.
So I would disconnect the Com wire that goes to my valves. Connect one wire of the sensor to the Com wire and connect the other wire of the sensor to the Com terminal.
That is different than my Rainbird controller. It had me connect both sensor wires to the 2 sensor terminals.
This was from the Rainbird controller manual:
“Most sensors have two wires or two terminals designed to be connected to the valve common wire. Instead of connecting to the valve common wire, connect these wires or terminals to the “SENS” terminals on the ESP Modular controller.”
Thanks again for your help. I would have never guessed the sensor terminals on the Orbit were for wireless sensors only.Spread the love!June 27, 2018 at 11:51 am #3998
One final question… do I put a jumper wire on the 2 sensor terminals or leave them empty?
I forget if this controller had a jumper wire originally in place or not. I am thinking it did.Spread the love!
