Master Valve and Pump Set-up Tips
To supply water to the various valves located throughout an irrigation
area, systems may use either a master valve or master pump. By
recognizing a specific
Address
and switch code, the controller sends a
signal telling the decoder when to activate the master valve or pump.
The switch code can vary depending on how your system was installed.
Below, we will cover some of the more common installations.
Using a Field Decoder With a Pump Start Relay
In this installation, a field decoder attaches to a pump using a pump
start relay. When setting up the controller, enter the field decoder
Address
in the master valve
Address
field.

NOTE:
Rain Bird recommends use of a FD-101 for small pump
start relays and a FD-102 for pumps 3/4 HP or greater.
