When a CDC switch is connected to the main board
terminal strip, the unit can be turned on and off
from a remote location. Up to 2000 feet of wire may
be used to connect a remote CDC switch to the unit.
A separate wire pair must be run from each CDC
switch to each Zoneline. Multiple units cannot be run
from the same CDC switch.
The remote CDC switch will be closed when the unit
is off.
REMOTE CDC SWITCH CLOSED = UNIT OFF
REMOTE CDC SWITCH OPEN = UNIT ON
Note: The Freeze Sentinel is still operational when
the remote CDC switch has turned the unit off. The
room air sensor must be installed and Freeze Senti-
nel dip switch must be in the down position for the
Freeze Sentinel to operate.
