Pump Start Relay

To prevent pump damage,
connect a jumper wire from
any unused station terminal
to a station terminal with a
control valve installed. If
there is a power failure and
the back up battery fails, a
default program will operate
all stations for 10 minutes.
Unused stations will still
attempt to operate the pump,
potentially causing damage
to the pump. If connected to
an operational valve, the
result would be an over
watered station instead of a
damaged pump.
Connecting a Pump Start Relay
NOTE:
Complete this section
only if you have a pump start
relay installed. A pump start
relay is an electronic device
that uses a current from the
controller to actuate a separate
electrical circuit to energize
a pump to provide water to
your system.
The controller should be mounted at least
15 feet (4.5m) away from both the pump
start relay and the pump. When a pump
start relay comes on it sends out surges
that may potentially cause damage to a
controller that is mounted to close. When
a pump is to be operated by the controller,
a pump start relay must be used. Hunter
offers a full range of pump start relays for
most applications.
1. Route a wire pair from the pump relay
into the controller housing.
2. Connect common wire to the screw
slot C (Common) and the remaining
wire from the pump relay to the MV
screw slot.
Relay current draw must not exceed
.35 Amps.
Do not connect controller
directly to pump – damage to controller
can result.
NOTE:
If a rain sensor is
installed with your SRC
along with a pump start relay,
the relay common must be
connected to the RS terminal.
