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
