Mv Settings; Set Up Master Valve (Optional) - Rain Bird ESP-LXME Installation, Programming & Operation Manual

MV Settings

The MV Settings option tells the ESP-LXME controller what type of
master valve (MV) is used by your irrigation system.
The ESP-LXME supports one master valve which must be set up in the
controller. Both Normally Open master valves (NOMVs) and Normally
Closed master valves (NCMVs) are supported.
Since Normally Open master valves (NOMVs) are always open, it's
sometimes helpful to cycle them closed for a minute in order to
maintain the continuity of your valve diaphragms and solenoids. The
controller can be programmed to perform this task automatically.
