VCB-X Confi guration
VCB-X Confi guration
Touch the < Confi guration> button to access the Confi gu-
ration Setpoints Screens.
For screens that contain radio buttons, touch the radio
button next to your selection. For screens with square
buttons, touch one or more square buttons to make your confi guration
selections for the unit.
 Check this Box for Celsius Temperature Scaling— Touch
the square button to select Celsius Temperature Scaling. Default
is Fahrenheit.
Installed Sensors
Touch the square button to select the sensors that are installed:
 Carbon Dioxide Sensor Installed
 Suction Pressure Sensor Installed
 Communicating Indoor Sensor Installed —This is the
E-BUS Digital Room Temperature Sensor or Digital
Temperature and Humidity Sensor.
 Communicating Outdoor Sensor Installed
—This is
the E-BUS Outdoor Air Temperature and Humidity Sensor.
Installed Expansion Boards and Modules
Touch the square button to select the Expansion Board(s) and Modules
that are installed. The available selections are as follows:

Config
HVAC Mode Enable Source
Touch the radio button to select the Temperature Sensor/Application that
will determine the Heating, Cooling, or Vent Mode of operation. Default
is Single Zone VAV. The available selections are as follows:

Single Zone VAV
—Recirculating unit using the Space
Temperature Sensor to determine the mode of operation.
Heating and Cooling are controlled to a Leaving Air
Setpoint. Space Temperature resets the Supply Fan VFD
speed to maintain the Space Temperature. Modulating
Heating and Cooling must be used for VAV operation.
Can be confi gured for CAV Heating using staged Heat.

Space Temperature —Typical recirculating unit using a
Space Temperature Sensor to determine the Heating,
Cooling, and Vent Modes of operation.

Outdoor Air Temperature
—This is for a 100% Outdoor
Air Unit (MUA) using the Outdoor Air Temperature Sensor
to determine the Heating, Cooling, and Vent Modes of
operation. Dehumidifi cation utilizes an Outdoor Air
Dewpoint Setpoint

Supply Air Cooling Only —This is for a standard Cooling
Only VAV unit with optional Morning Warm Up. In the
Occupied Mode, the unit will be in the Cooling Mode
controlling to the Cooling Supply Air Setpoint.

Return Air Temperature —Optional recirculating unit
confi guration using the Return Temperature Sensor to
determine the Heating, Cooling, and Vent Modes of
operation.
Static Pressure Control
This confi guration option is available if expansion module EM1 is
installed and confi gured. Default is Fan VFD. The options are:

None
—This unit is not controlling Duct Static Pressure.

Fan VFD or Single Zone VAV
—This unit has a Supply
Fan VFD that modulates to control the Duct Static Pressure.

Bypass Damper
—This unit uses a Bypass Damper to
control the Duct Static Pressure.
