Connecting A Pump Start Relay (Optional) - Hunter ICC2 Owner's Manual

CONNECTING A PUMP START RELAY
(OPTIONAL)
Complete this section only if you have a Pump Start Relay
installed. The ICC2 Controller has one Pump/Master
Valve (P/MV) output, which is capable of activating either
a normally closed Master Valve or a Pump Start Relay.
A Pump Start Relay is an electrical device that uses the
irrigation controller to activate a pump, when used to supply
water to a system. When a pump is to be operated by the
controller, a Pump Start Relay must be used. Do not connect
the controller directly to the pump as it will result in damage
to the controller. The P/MV output is rated for up to 0.56 A.
1. Route the Pump Start Relay wire pair into and out of the
cabinet similarly to the station wires.
2. The P/MV output is located on the power output module
in the upper left corner of the controller.
3. Hunter Pump Start Relays come with two yellow 24 VAC
flying leads, one of which will connect to the common
"COM" terminal and the other to the P/MV terminal.

Installation Instructions
4. Hunter recommends that the controller be mounted
at least 4.5 m away from the Pump Start Relay. While
most of the time the distance between the controller
and Pump Start Relay does not create any problems,
sometimes the wires on the 24 VAC coil can allow
electromagnetic noise to travel back to the controller.
The 4.5 m distance between controller and Pump Start
Relay helps dampen any potential electromagnetic
noise.
5. The Pump Start Relay can be activated in accordance
with any particular station. The controller default setting
is on to activate the Pump Start Relay output with all
stations; however, it can also be programmed to be
active or disabled with any individual station.
