GENERAL `

The three sensors combined on this product

are for wind speed, rainfall and temperature(near-freezing conditions). Each sensor operatesindependently of the other; therefore, any or allof them may be switching at a given moment.See the enclosed separate product installationinstructions for details on each sensor's operationand settings. Use only the “mounting” detailscontained on this sheet.

MOUNTING

The weather station is designed to mount on apost of 2" PVC pipe. However, any combinationof pipe and fittings can be used to tailor aninstallation. The enclosed “reducer” fitting has twopurposes: 1) It allows for the use of 1 / 2" PVC pipefor shorter mounts, and 2) Screwed down ontosurface (wood post or deck), it acts as a base forthe weather station to fit onto.

Important: For most accurate temperature sens-ing, rotate the weather station so the thermostatportion points north.

WIRING

Wiring to the Hunter SRC Controller

The Mini-Weather Station connects directly to theSRC. This allows you to easily override the sensorby using the RUN (BYPASS SENSOR) positionon the dial.

1. Route the wires from the Mini-Weather Stationup through the same opening used for valvewiring.

2. Connect one wire to the RS terminal and otherto the C terminal (See Figure 1).

3. Connect the valve common to the RS terminal.

Wiring to the Hunter ICC Controller

The Mini-Weather Station connects directly to the

ICC. This allows you to easily override the sensorby using the Sensor switch on the front panel.

1. Remove the jumper from the two “SEN”terminals.

2. Route the wires from the rain sensor upthrough the same conduit opening used forvalve wiring.

3. Connect one wire to the terminal labeled“SEN” and the other wire to the other “SEN”terminal (See Figure 2).

Other 24 VAC Controllers

All three sensors are electrically connected ina series, so only two wires need to be used toconnect to the irrigation controller. Use the green

and silver (clear insulation) wires to hook up tonormally-closed logic situations (See Figure 3).Follow the wiring instructions in any of the sepa-rate sensor manuals, or place the two wires onthe controller's “sensor input” screw terminals ifavailable (See Figure 4). For controllers withnormally-open sensor inputs (most Toro models),please consult factory.

Note: For extending wires, use wire 18AWGor heavier.
