How long does it take for a Hunter rain sensor to dry out?

Troubleshooting

The dry out time could be as little as 4 hours depending on the weather conditions (temperature and humidity) and the rain threshold that is set. If the weather conditions remain cold and damp, your sensor could be active for months.

Hunter rain sensors and Solar Syncs have two seperate options for setting a rain shutdown threshold:

The Mini Clik uses a spindle adjustment to set the amount of rain you want the sensor to witness before it shuts down the system. This amount can be set by adjusting the spindle on top of the sensor and the range is 1/8" (3.17mm) to 1" (25.4mm).

A vent ring around the base of the Mini Clik's spindle assembly can be used to prolong the sensor's dryout time. Exposing more of the internal dryout rings will naturally dry the sensor out faster than if the vents are closed.

The Rain Clik and Solar Sync models come equipped with a Quick Response feature that shuts the system down upon contact with the first increments of rainfall.

The adjustment you make will be to the sensor's dry time ( + Dryout Time - ); How long do I want it to take before the sensor allows the system to run again?
