HPC - Connecting Station Wires
1. Route valve wires between control valve location and controller.
2. At valves, attach a common wire to either solenoid wire of all valves. This is most
commonly a white colored wire. Attach a separate control wire to the remaining wire of
each valve. All wire splice connections should be done using waterproof connectors.
3. Route valve wires through the conduit and attach conduit to one of the openings on the
bottom of the cabinet.
4. Strip ½" (13 mm) of insulation from ends of all wires. Secure the valve common wire to
“COM” (Common) terminal. Attach all individual valve control wires to the appropriate
station terminals.
HPC - Connecting Sensors or
Flow Meters (Optional)
HPC Controllers with date codes of JAN 2023 and newer include two sensor inputs. The
SEN-SEN terminals from the original HPC Controllers have been split into SEN and SEN-2
to allow for two separate sensor installations (i.e., flow + rain sensor). Sensors now wire
separately across the Common terminal (COM).
