SENSOR WIRING
Most sensors, either Rain or Moisture type, are generally 2 or 3 wire.
The 2 wire sensors are connected to terminal 1 and 2 on the sensor terminal block (See
Figure 7)
Most 3 wire sensors will work if connected as follows: (See Figure 7)
Common wire to terminal #2
Valve common connects to terminal #1
24 VAC wire connects to terminal #3
Please check sensor wiring instructions for further details.

TAPPING WIRES TO LOCATE VALVES IN THE FIELD
DON'T – Do not turn a station on and tap a wire to the controller's station
terminal/wire to see what valve in the field is connected to it. This is damaging to
both mechanical and solid state controllers and will cause the controller to go into a field
wire fault detection mode. The simple method shown below is safe and will work for
both types of controllers.
1. Use Manual Station to turn on Station 1, perhaps for 1 hour.
2. Flip the Rain Switch to the “No Watering” position.
3. Touch the wire from the unknown field valve to the controller's Station 1 terminal/wire.
4. Flip the Rain Switch to the “Automatic Watering” position and the valve on that wire
will be activated.
5. When you know what valve it is, flip the Rain Switch off before removing the field
wire from the controller's station terminal/wire.
6. Choose the next field wire and start the process over at Step 2.
7. When all done, turn off Station 1.
