Freeze Sensor Site Selection

In addition to the rain sensor site conditions listed on page 10, the following conditions are necessary to ensure optimum freeze sensor operation. For best results, the sensor should be:

•Located in the coldest portion of the landscape.

•Away from direct exposure to morning sunlight.

•Away from any heat producing or storing device, equipment or appliance such as a pool/spa, heater, water heater, chimney or hot air vent pipe.

CAUTION: The rain/freeze sensor module should be regularly inspected for damage and manually tested to ensure proper operation.

The Toro Wireless Rain/Freeze sensor system is NOT intended for farm/crop freeze protection and must not be used for this purpose.

Important: Visual checks and prudent manual watering suspension must be used in conjunction with any freeze sensor. A freeze sensor should only be relied upon as an aid to conscientious watering practices, including frequent visual checks. Air temperatures may be above freezing while the ground and vegetation temperatures remain below freezing. Due to sensor location and sunlight exposure, actual air temperature may be lower than measured by the sensor. Operation of the sprinkler system during these conditions may cause icing. Freeze sensor response time may not coincide with extremely rapid temperature drop, enabling automatic irrigation to occur.
