I am trying to convert my Rainbird to the ImoLaza 3 and I am having some trouble trying to figure out what to do with the S1, S2. I don't have a rain sensor, they told me to keep the yellow sensor jumper wire according to the instruction. You can see the picture attached below. Now, I wonder if I need to transfer this jumper to ImoLAZA? S1 and S2. Once again, I don't have a rain sensor and I get no plan to buy one now.
What say you?
