I have a 1 1/4" white rodger zone valve that I am trying to hook to blt controller. I do not think it will work, but before I remove I want to see if anyone had any ideas. I can power the valve fine and have it stay closed however I trying to get it to open is the challenge. I currently have the 1 and 2 terminal hook to the 24" volt power source in the blt and that keeps it closed. Now to open, should terminal 4 on the blt complete the circuit and open the valve? Do I need to send power to the terminal 4 on the zone valve or do I need to close the circuit (which is all I think the blt does (no power).
