Connecting the Power Source (cont.)Toro WirelessRain Sensor566Connecting a Rain Sensor (optional)A rain sensor is an optional control device that connectsdirectly to the TMC-212 to automatically interrupt automaticcontroller operation during rain.A sensor bypass switch is provided to enable sensoroperation to be disabled as needed.A sensor configuration switch enables the controller to workwith a normally-open or a normally-closed rain sensor.When the rain sensor absorbs moisture it signals theTMC-212 to suspend automatic watering operations.The No Watering symbol is displayed until the sensordrys out and automatically resets.When the No Watering symbol disappears, controlleroperation will resume as programmed.1. Route the sensor wires from the device into the controllerhousing through the access hole provided.2. Remove the plastic insert from the Sensor terminal connectors.Connect sensor wires per the instructions providedwith the device.3. Set the Sensor Configuration Switch (5) to NC(Normally Closed) or NO (Normally Open) operationas required by the type of sensor connected.4. Set the Sensor Control Switch (6) as required: ENB(enable) allows the rain sensor to interrupt watering;DIS (disable) bypasses the rain sensor input.IMPORTANT: Do not use the ENB switch positionwith the NC switch position unless a normallyclosedrain sensor is connected. Watering operationwill be suspended if this condition occurs.5. Refer to the instructions provided with the rain sensorfor operating information.13
