GBD-X Controller
SS1029
DESCRIPTION: The GBD-X Controller has the ability to monitor up to 12 temperature
sensors and broadcast the average of those sensors to a VCM or
VCM-X controller. It also includes the ability to read CO2 sensors and
either average or find the highest reading to be broadcast to the same
controllers. It also provides a 0-10 VDC proportional reset voltage on
Analog Output #1 based on the level of CO2 as it rises from an
adjustable minimum setting to an adjustable maximum level.
Analog Output #2 provides a 10.0 VDC signal whenever the CO2 is
above the minimum setpoint.
Relay #1 is activated whenever the CO2 rises above the minimum
setting and de-activates when it falls 5 PPM below the setpoint.
Relay #2 is activated whenever the CO2 rises above the maximum
setting and de-activates when it falls 5 PPM below the setpoint.
LIMITATIONS: When using the GBD-X controller you must have the following
minimum equipment installed on your controls system:
Single Loop System requires either a CommLink or a MiniLink to allow
broadcasting to and from the GBD-X controller.
Multiple Loop Systems require both a CommLink and a MiniLink to
allow broadcasting to and from the GBD-X controller.
Only 6 sensors can be connected to a single GBD-X controller. If more
than 6 sensors are needed then a second GBD-X controller board for
sensors 7 to 12, is required. The global analog broadcast channels are
user selectable.
Celsius temperatures are not supported.
Only the VCM and VCM-X Controllers can read the CO
for IAQ
2
operations.
Any VCM or VCM-X on a loop can have broadcast devices sending
it data since the global receive channel is fixed at Global Analog
#13 for temperature (if no space sensor installed) and #14 for CO
2
(if no sensor is installed).

SOFTWARE: PRISM II version 3.1.1 or higher is required to program and monitor
the GBD-X controllers.
APPLICATIONS: Up to 6 Space Temperature Sensors
One GBD-X controller with up to 6 Space Temperature Sensors
wired in. Set the GBD-X controller to broadcast on channel 13.
7 to 12 Space Temperature Sensors
Two GBD-X controllers with up to 6 Space Temperature Sensors
wired in on each. Set one of the GBD-X controllers to broadcast on
channel 13. Set this one to also receive on channel 23. Set the
other GBD-X controller to broadcast on channel 23.
Up to 6 CO2 Sensors
One GBD-X controller with up to 6 CO2 Sensors
wired in. Set the GBD-X controller to broadcast on channel 14.
7 to 12 CO2 Sensors
Two GBD-X controllers with up to 6 CO2 Sensors
wired in to each. Set one of the GBD-X controllers to broadcast on
channel 14. Set this one to also receive on channel 24. Set the
other GBD-X controller to broadcast on channel 24.
CAUTION: You cannot mix Space Temperature Sensors with
CO2 Sensors on the same controller!
