Pump Start Relay
4.5 Meters Minimum (15')
To Pump
CONNECTING A PUMP START RELAY
NOTE: Complete this section only if you have a pump
start relay installed. A pump start relay is a device that
uses a signal 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 4.5 m away from both the
pump start relay and the pump.
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 P screw slot.
Relay holding current draw must not exceed .28 amps. Do not connect
controller directly to pump—damage to controller can result.
CONNECTING A WEATHER SENSOR
A Hunter weather sensor or other type of micro-switch weather sensor
can be connected to the EC. The purpose of this sensor is to stop
watering when weather conditions dictate.
1. Remove the jumper that is attached across the SEN terminals of
the controller.
2. Connect one wire to the SEN terminal and one to the other
SEN terminal.
NOTE: If the rain sensor is interrupting irrigation you can
bypass it by using any of the following: MANUAL-ONE
STATION, MANUAL-ALL STATIONS, or ONE TOUCH START
AND ADVANCE. See section “Rain Sensor Bypass” for
more information.
POWER FAILURES
Due to the possibility of power failures, the controller has non-volatile
memory. Programmed information will never be lost. The controller
will keep the correct time for up to 1 month without power. Normal
watering will resume when AC power is restored.
