Installation Instructions

CONNECTING STATION WIRES

Each ICC2 Controller is supplied with a factory-installed
base module for up to 8 stations (ICM-800). Multiple
additional modules may be added in increments of four
(ICM-400), eight (ICM-800), or one 22-station expansion
module (ICM-2200). Each station module has its own
common terminal, which runs in conjunction with the
corresponding station terminals within the module. Each
station output is rated for 0.56 A maximum, which can
safely operate up to two Hunter solenoids simultaneously.
1. Route station/valve wires between the control valve
and the controller.
2. At the valve(s), attach the common wire to either
solenoid wire for each individual valve. This is most
commonly a white-coloured wire. Attach a separate
control wire to the second remaining solenoid wire of
each valve. All wire splice connections should be made
using waterproof connectors.
3. Route all common and valve control wires through an
incoming conduit to the controller. The conduit can
attach to any of the knockout openings at the bottom of
the cabinet.
4.
Strip 13 mm of insulation from the ends of all wires.
Secure the valve common wires to corresponding "COM"
terminals. Attach all individual valve control wires to the
appropriate station terminals.

CONNECTING A MASTER VALVE (OPTIONAL)

Complete this section only if you have a Master Valve
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
Master Valve is typically installed at the supply point of the
main line and opens only when the automatic system is
activated. The purpose of a Master Valve is to shut off the
water to the irrigation system when none of the station
valves are operating. It's also beneficial for shutting off a
system when a zone or mainline develops a leak or break.
The P/MV output is rated for up to 0.56 A.
1.
Route the Master Valve 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 ICC2 Controller.
3. Connect either wire from the Master Valve to the
P/MV terminal, and connect the remaining wire to
the common "COM" terminal.
4. The Master Valve can be activated in accordance with
any particular station. The controller default setting is
on to activate the Master Valve output with all stations;
however, it can also be programmed to be enabled or
disabled with any individual station.
