I recently purchased the OSPI board to mount the Raspberry Pi. I am looking to replace my hunter sprinkler system.
My system has 6 zone valves and one Main valve. For a zone to be turned ON, the zone valve and main valve must be ON.
I am not sure how i can connect the Main valve to the OSPi. Should it just be connected as one of the ports ? Then how do i configure the programs (say the interval program) to turn ON this valve too every time a zone valve is activated ?
I could not find this info the OSPi manual.
I would appreciate any help.
Hi rkovvur ,
What you are referring to as the “main valve” is know as the master valve in OpenSprinkler terminology.
You can hook up the master valve to any of the first 8 stations on the OS. Then go into options and select that station as the master.
You will also need to go to the Stations page. When a master has been selected, you will see a column of check boxes next to each station for activating the master.
On the options page you can also set an optional delay for the master.
