365/7-Day Astronomic Electronic Control
The ET2800 Series 365/7-Day Astronomic Electronic Controls
feature independent 7-day programming for convenient exibility
when load switching differs daily. These electronic controls provide
dependable and uncomplicated performance, plus to-the-minute
programming for accurate load control and reduced energy costs.
Up to 48 ON and 48 OFF events can be preset to automatically repeat.
Each event can be applied to any combination of circuits and days.
Each circuit can be independently scheduled for Astronomic
(Dusk/Dawn) ON/OFF events. In addition, the programming can be easily
disabled by changing to the manual operating mode. An additional mode
of operation allows for ON/OFF buttons to be used as a 2-hour override,
in compliance with current regulations. Manual circuit control buttons
operate circuits independently, based on the mode of operation.
50 Holiday Block Scheduling exception dates are available to prevent
regularly scheduled events, or allow for a holiday schedule. All models
come equipped with a supercapacitor to provide time and date retention
for a minimum of 100 hours, and do not require batteries. Each
electronic control is housed in a lockable enclosure for vandalism
and tampering protection.
