NOMV Cycling
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.

NOTE:
Each NOMV will be cycled closed for 60 seconds on the

NOMV is shut, choose a time when irrigation is not scheduled for
this operation.
