Connect Pump Start Relay
Connect an optional Pump Start Relay to the ESP-
RZ controller.
Pumps are used in some places to draw water from a
well or other source. If you are activating a pump from
the controller, 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 dierently
at the water source.

NOTE: the ESP-RZ 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 terminal block.

 Connect the common wire from the pump start

NOTE: 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)
