DESCRIPTION
The BU – 6 system allows for automatic backup
of the computer system.
The Real-Temp
backup lets the computer operate independent
from the backup thermostats. Backup
thermostats are automatically energized
whenever the controller losses power. Power
for the backup system utilizes its own isolated 24
VAC transformer. Since this transformer is not
connected until the failure occurs, it is not easily
damaged by surges. Power for the backup
system is taken from the minimum ventilation
240 VAC power line and is independent of the
controller AC supply. This unit is supplied in a
gasketed fiberglass enclosure.
