CONNECTING VALVE WIRES
Connecting Station Valve Wires
Each station module that has been inserted has a grouping of six station 
screw terminals corresponding to that particular expansion slot. Once a 
station module is installed in a module slot, the station screw terminals 
assigned to that module, which are located directly below the station 
module, become active.
Each station output is rated for 0.56A max, or enough to operate two 
Hunter AC solenoids simultaneously. 
1.   Route valve wires between control valve location and the controller.
2.   At the valves, attach a common wire to either solenoid wire of all the 
valves. This is most commonly a white colored wire. Attach a separate 
control wire to the remaining wire of each valve. All valve wire splice 
connections should be done using waterproof connectors.
3.  Open the faceplate at the controller to expose the numbered station 
terminals.
4.   Route valve wires through the conduit and attach the conduit to the 
controller at the 1 ½" (37.5 mm) opening at the bottom of the cabinet.
5.   Strip ½" (13 mm) of insulation from the ends of all the wires. Secure 
the valve common wire to one of three C (Common) terminals located 
of the Power and Accessory terminals. All three common terminals are 
active, so the valve common wire may be connected to either one. 
Attach all the individual valve control wires to the appropriate station 
terminals.

Connecting a Master Valve or Pump Start Relay
Complete this section only if you have a Master Valve or Pump Start Relay 
installed. The I-Core controller works with a normally closed master valve 
that is typically installed at the supply point of the main line that opens only 
when the automatic system is activated. A pump start relay is an electrical 
device that uses the irrigation controller to activate a pump to provide 
water to your system.
The Master Valve or Pump Start Relay connection is located on the 
bottom row of the Power and Accessory Terminals, and is labeled P/MV. 
This terminal will supply 24 VAC, 0.32A max, for a single Master Valve 
solenoid. For a Pump Start Relay, the relay holding current draw must 
not exceed 0.28 amps. If using a Pump Start Relay, it is recommended 
that the controller be mounted at least 15' (4.5 m) away from both the 
pump start relay and the pump. 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 — damage to controller will result.
1.   Route valve wires between Master Valve or Pump Start Relay location 
and the controller.
2.   At the Master Valve, attach a common wire to either solenoid wire of 
the valve. Attach a separate control wire to the remaining solenoid 
wire. At the Pump Start Relay, attach either wire to one of the yellow 
wires coming from the Pump Start Relay. Attach the remaining wire to 
the other yellow wire at the Relay. All wire splice connections should 
be done using waterproof connectors.
3.  Open the inner facepack door at the controller.
4.   Route the valve wires into the controller via the eld  
wire conduit.
5.   Connect either wire from the Master Valve or Pump start Relay to the 
P/MV terminal located on the bottom row of the Power and Accessory 
terminals. Connect the remaining wire to the C (Common) terminal 
that is located directly to the left of the P/MV terminal.
The Master Valve or Pump Start Relay can be activated according to a 
particular station. The conguration of assigning the Master Valve or Pump 
Start Relay according to a particular station will be covered in the Set Pump 
Operation (pg. 18).
