The DS-5 is essentially a DS-2B fitted with a dual 30A @ 240 VAC load control contact set. It is primarily designed for larger satellite antenna/broadcast tower deicing and pavement snow melting applications. Specifically, any job that a DS-2B can perform a DS-5 can perform with double the load handling capability.

A new feature has been added to the DS-5. If the switch is placed in "Manual On" for less than 2 seconds, then switched back to "Automatic" the controller will execute one delay off cycle. The delay off cycle is determined by the DEL switch setting and the DEL adjustment, i.e., 2 minutes in "sensor" mode, 30-90 minutes in "controller" mode. This can be used to clear surfaces with a frost or hail buildup without the danger of leaving the system in a continuous "Manual On" condition. "Standby/Reset" can still be used to clear this delay off cycle. The DS-5 is also compatible CDP-2 remote control/status panels.
