Thanks for the reply, I had already set the master stations are checked as “Active” and expansion board marked as “1” in Options.
I have still only the master and first 4 stations working….
Input voltage 29vac, master valve shows the same with stations showing 28.7vac (due to distance??).
So the problem still remains that stations 6,7 and 8 showing 28.7vac when system is on and master valve showing 29vac but no water flow. However when I manually turn the master valve on I get water flow. It also show it all working in the LCD display.
3) On the controller, clicking pushbutton B3 will change the display to expansion board 1 (E1).
Whoops missed this one.
