Sensor Wiring to VCB-X Controller
Wall Mounting
The OE256-05 Wall Mounted E-BUS CO
2
Sensor utilizes a sub-base
mounting plate with a modular phone jack providing quick and easy
mounting and wiring. The wall-mounted sensor’s sub-base is compat-
ible with standard junction boxes. A locking screw secures the assembly
to the wall.
Optional Mounting Plate
Included with the Digital Room Sensor is a mounting plate that
can be used, if necessary, to cover the sensor sheet rock opening.
This mounting plate screws onto the back of the housing base.
The mounting plate is then mounted and covers the recessed space
in the wall. A locking screw secures the sensor to the wall. See
Figure 6, page 7 for dimensions.
Wiring to the VCB-X Controller
The OE256-05 Wall Mounted E-BUS CO
2
Sensor connects to the
VCB-X or VCC-X Controller with an EBC E-BUS expansion cable. It
can be daisy-chained
with the Digital Room Sensor (OE217-02, OE217-
03, OE217-04) for applications requiring both a space CO
2
sensor and
space temperature sensor. Refer to Figure 2 for instructions (VCB-X
Controller shown).
