PRO-C 400i does not work. Differences to 300i?
Hello,
I wanted to install a solar sync on my PRO-C (300i from 2013). Since it does not have the setting for it on the dial, I ordered a new PRO-C Controller (400i from 2021).
I used the same wiring and programmed it. Even it showed everything fine on the display - it never acitvated the sprinkler system.
Then I removed the solar sync, tried it again and got the same result.
I recognized the Base Modules coming with the Controllers are not compatible. (Mechanical blocking the fitting).
My question is:
-Are the Controllers compatible with the old system?
- What is the difference and how can I make it work?
I am glad for every hint.
Thank you winklef
