Description
Depending on the desired
configuration, connect the relay cables
to either N.O. or N.C. Relays 1 and 2
are controlled by either internal events
or by BACnet; relays 3 and 4 are
driven only by internal events.
Place the jumper over the Shutdown
header pins to reset or restart the
system.
Place the jumper over the header pins
to include resistors to attenuate
communication echoes.
