4. Activate the rain sensor within Cyber-Rain by selecting the Rain Sensor Installed check box on the Controller page, indicating that you have connected a
rain sensor to your controller.
5. Set the rain sensor type and desired delay hours. The default is set to 24 hour delay after the rain sensor has dried.
Rain sensors are sold in two different varieties, normally open, and normally closed. Normally open controllers have two wires connected to a switch which does
not provide a path for electrical current when dry. When rain is detected, the sensors close the circuit and allow a path for electrical current. Normally closed
sensors provide a path for electrical current until rain is detected, at which point the switch is opened and an open circuit is produced.
It is important to choose the correct sensor configuration. Choosing the wrong configuration will cause rain sensor holds. Cyber-Rain’s default setting is normally
closed. Please determine your sensor type from your sensor’s documentation. To verify the correct sensor type has been chosen, check the Run Status panel on
the Controller page. If there is a Rain Sensor Hold and the rain sensor has not been activated by actual rain, the wrong sensor type may have been selected in the
Rain Sensor Settings panel on the Controller page.
