3.2.1.2 Normally Closed Master Valve Operation
If you have a Master Valve, which requires power to open the valve, but uses no pump, then
connect the Master Valve solenoid to the MV pin and the common wire to the white wire of J4, as
depicted in Figure 5 - Master Valve Electrical Connection.
If more than one controller will control the Master Valve, then the controllers must be isolated from
one another. Contact your local distributor or Rain Master Irrigation Systems for the pamphlet on
how to install multiple controllers (RMIS Technical Bulletin 018). Using the SETUP function,
select the NC (Normally Closed) Valve type for all programs (1, 2, 3, and 4).
Figure 5 - Master Valve Electrical Connection
WARNING: ALWAYS TURN-OFF POWER before changing or modifying field, senor
or power wiring within the controller. Dangerous voltage and current exist
within the controller which may damage the controller if improperly
connected or shorted.
3.2.1.2.1 Simultaneous Use - Normally Closed Master Valve and Pump
If you have a Master Valve which requires activation to open, and a Pump which is always needed
when irrigating, connect BOTH the Master Valve solenoid and Pump starter to the MV and Master
Valve common terminals as shown in Figure 6 – Master Valve and Pump Electrical Connections.
If the Pump starter operates on 24 volts AC and the combination of the Master Valve Solenoid and
Pump starter require more than 1 ampere of current, you will need an isolation relay (RMIS part #
RLY1 or equivalent) and an additional source of 24 volts AC, as depicted in Figure 7 – Master
