NOTE: If The Sensor Is Used
With The Digital Room Sensor, The
CO Sensor Always Connects To The
VCM-X Or RNE Controller First Using
A TSDRSC Cable Of The Required
Length. The Digital Room Sensor
Then Connects To The CO Sensor
With Another TSDRSC Cable.

Wall Mounted Space CO

Sensor Wiring to HVAC Unit Controller
Wall Mounting
The OE256-01 Wall Mounted Space 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 8, page 10 for dimensions.
Wiring to the HVAC Unit Controller
The OE256-01 Wall Mounted Space CO
2
Sensor connects to the VCM-X
E-BUS or RNE Controller with the TSDRSC modular cable. It can be
daisy-chained
with the Digital Room Sensor (OE217-00 or OE217-01)
or used separately from a Space Temperature Sensor (OE210, OE211,
OE212, or OE213) for applications requiring both a room CO
2
sensor
and room temperature sensor. Refer to Figure 2 for instructions (VCM-X
E-BUS Controller shown).
