Freeze Temperature (threshold): The freeze sensor activation
threshold can be adjusted from 39 °F, (default) down to 35 °F,
or increased to 45 °F, in 2° increments.
Important: Freeze sensor operation should be used only when the
watered area can be visually monitored. While the Freeze Sensor is
designed to cancel watering when air temperature is near freezing,
automatic watering can occur in certain circumstances. For example,
the air temperature may rise slightly above the sensor threshold, while
the temperature of the adjacent walkways remains below freezing.
Watering in this condition can result in unsafe walkway conditions. The Freeze Sensor feature is not intended to
replace any winterization procedures normally used to prevent freeze-related irrigation system damage.
Dry-out Days: This setting determines the minimum length of time that must elapse after the release of
a rain/freeze hold, and automatic watering can resume. By default, the dry-out period is 1/2 day (12 hours),
and is adjustable from 0 to 3 days in 1/2-day increments.
