INSTALLATION INSTRUCTIONS
Terminal Strip
All zone, pump and sensor wire connections made inside the EZ Pro
™
Jr. utilize
screw type connectors that require a small screwdriver. The terminal strips in
the controller accept 12 AWG (2.1mm) wire or smaller.
Connecting Master Valve or Pump-Start Relay
The EZ Pro
™
Jr. is equipped with a shared circuit to operate either a pump-
start relay or a master valve. Connect one wire from the pump-start relay to
COM (common) on terminal strip, the other to PMP/MV (pump/master valve)
on the terminal strip. Refer to the pump-start relay manufacturer’s instructions
for specific installation details.
Connecting Rain/Moisture Sensor
The EZ Pro
™
Jr. is equipped to operate a sensor with normally-closed leads.
To install a sensor, remove the factory-installed jumper wire from the sensor
connector on the terminal strip and insert the sensor wires. Refer to the
sensor manufacturer’s instructions for specific installation details.
(See figure 2)
If a sensor has suspended watering, the sensor indicator segment will
appear on the LCD. The symbol will go off when the sensor has dried out. The
EZ Pro
™
Jr. will resume operation based on the selected program.
NOTE: Manual operations will ignore the rain sensor
