What does the DEL Dip Switch mean on the DS8?
DEL or Dip Switch 3 activates the Delay-Off feature on the DS8. This feature allows the DS8 controller to continue to operate even after it senses the precipitation has stopped. This will prevent any residual moisture from re-freezing into ice. When this switch is turned OFF, the system will only have a delay off cycle of only two minutes. If this switch is ON the system will continue to operate for the length of time determined by the LD (long delay) switch. This can range anywhere from 30 minutes to 6 hours and be tailored to your specific installation.
Please refer to the instruction manual for further instructions.
