The ET90000 365-Day Astronomic Time Switch injects a powerful presence into the energy controls market with eyebrow-raising memory that accommodates up to 4,000 events, plus holiday and exception programming.
A convenient USB connection and Ethernet capabilities enable in-field schedule updates and firmware upgrades to be installed in one central location. The intuitive time switch automatically detects and adjusts voltage between 120 and 277 VAC, at 50 or 60 Hz to eliminate manual voltage adjustments during installation.
The ET90000 meets the demanding needs of most facility schedules with availability in 1, 2, 4, 8, 12, and 16-circuit configurations. It can also be used with external devices, such as wall switches and occupancy sensors, to manually turn on and time off.
