Rain Bird ESP-RZXe Installation Guide And Operation Manual

11
Connect Pump Start Relay
Connect an optional Pump Start Relay to the ESP-RZXe
controller.
Pumps are used in some places to draw water from a well or
other source. If you are activating a pump from the control-
ler, you must install a pump start relay.
A pump start relay connects to the controller in the same
way as a Master Valve, but connects differently at the water
source.

NOTE: the ESP-RZXe controller DOES NOT provide
main power for a pump.
 Connect the Relay Input wire from the pump start
relay to the master (M) terminal on the controller ter-
minal block.

 Connect the common wire from the pump start relay
to the COMMON (C) terminal.
NOTICE
To avoid possible pump damage when using a pump
start relay, connect a short jumper wire from any unused
Zone terminal(s) to the nearest Zone terminal in use.
For example, if a 4 Zone controller model is in use with
only two Zones connected, route the terminals for Zones
3 and 4 to the nearest active terminal (in this example,
Zone 2)
Connect Rain Sensor
Connect an optional rain sensor to the ESP-RZXe con-
troller.
 On the terminal board, remove the jumper wire from
the SENS terminals.
