Question
I have the following irrigation components installed:

- Hunter Pro-C Controller w/2 add-on 3-station modules for a total of 9 stations

- Hunter PGV valves w/master valve

- Hunter wireless rain / freeze sensor

Problem: Master valve will not activate for stations 1-3 (No audible solenoid click) but, will activate for stations 4-9 (Audible click of solenoid). Individual valves for 1-3 will activate (Audible click of the solenoid)and stations 1-3 will flow water if master valve relief valve is manually opened.

Background: Stations 4-9 have been working fine for over a year with no problem and continue to work fine. I recently tried to setup and use stations 1-3 which had been off up until this time since the planting beds were not complete. As mentioned above master valve is not turning on but station valves are turning on.

Answer
Have you programmed the PRO-C to turn the MV on for zones 1-3? Just asking since you mentioned the zones were activated after the other zones had been running.

Please make sure to follow the instructions to ensure the module is locked into position and it did not come loose.

Another option would be is the module is not functioning properly.


Please update with answers when you are able.
