Astronomical Clock
General
The WRT3540 ASTRONOMICAL
CLOCK is a system level device used to
schedule loads, or combinations of
loads on a daily, weekly, monthly, or
yearly basis. This unit features simple
keypad programming that does not
require the use of any other external
programmer. The WRT3540 can be
mounted remotely from the lighting
panel, and only requires the NexLight 2wire bus plus a 24Vac supply to
operate.
Features
•
•
Schedules up to 30 separate
channels.
Seamless integration with NexLight
lighting control system allowing
access to all loads and combination
of load groupings that are defined
•
Includes automatic Daylight Savings
Time function with user definable
start and stop date.
•
Lights can be controlled with sunrise
or sunset by entering longitude and
latitude coordinates.
•
Sunrise and sunset times can be
before or after by +/- 90 minutes.
•
Time-of-day setting will remain
backed for 24 hours during a power
outage. Scheduled programs are
stored in EEPROM and retained
without power for 7 years.
•
Information is displayed using a
clear, easy-to-read LCD display with
backlighting available.
•
Programmable to automatically
consider holidays and other special
days.
•
Includes ability to create 2 ‘Special
Day’ programs that can be used for
holidays, activated via NexLight wall
switch.
•
Astronomical Clock programs can be
placed on standby function via
NexLight wall switch.
•
Can link up to 6 Astronomical Clocks
together thereby creating a total of
180 time managed time schedules.
•
Linked clocks are time synchronized
every hour to the designated 'Master'
clock.
•
Backward compatible and Integrates
with WRT2000 and WRT2040
Transmission Units
•
Fully compatible with Honeywell
LiteCom® system.
