Valve, Pump Relay and Sensor Installation

Step 1 – Route valve wires from the valves, master valves, pump
relay and/or sensor into the controller cabinet.
Note: 18 AWG (1.0 mm
connection cable can be used.
direct burial and is color-coded to simplify installation.
It can be routed directly into the controller through the
access hole provided for valve wire conduit (if conduit is
not used).
Step 2 – Connect valves, master valves and pump start relay
to the valve wires - Connect the white color-coded wire
from the cable to one wire from each valve solenoid and/
or pump relay. (Either of the two wires from the solenoid
or pump relay can be used for this connection.)
connection will be designated as the valve common wire
(COM).
Connect a separate cable wire to the remaining wire
from each valve solenoid. Note the wire color-code used
for each valve and the valve it controls. You will need
this information when connecting the valve wires to the
controller.
Step 3 – Secure all wire splices using wire nut connectors. To
prevent corrosion and possible short circuits, always use
an insulated wire nut, grease cap or similar waterproo ng
method.
Step 4 – Connect valve wires to the controller - Secure the valve
common wire (white) to either of the two terminals
labeled COM. Secure the individual valve wires to the
appropriate valves they control, Valve 1 to terminal 1,
Valve 2 to terminal 2, etc.
– Connect master valve/pump relay wires to the
Step 5
controller - Secure the valve common wire (white) to
either of the two terminals labeled COM. Secure the
Master Valve or Pump Relay wire to the terminal labeled
MV/PUMP.
Caution: To prevent controller damage, do not
connect the pump motor starter directly to the controller.
Step 6 – Connect sensor wires to the controller - Remove the
jumper wire from the SENSORS terminals. Secure the
two sensor wires to the sensor terminals. Refer to the
provided sensor instructions for further installation
instructions.
