LOSS OF CONTROL
WARNING
LOSS OF CONTROL
• The designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control
functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are
emergency stop and over travel stop.
• Separate or redundant control paths must be provided for critical control functions.
• System control paths may include communication links. Consideration must be given to the implications of anticipated
transmission delays or failures of the link.1
• Each implementation of equipment utilizing communication links must be individually and thoroughly tested for proper operation
before being placed into service.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
ELECTROSTATIC DISCHARGE

through BACnet will not have the same outcome. If changes need to be done remotely through BACnet, use priority 1, 2 or 3, or
write to relinquish default (priority 17).
Introduction
This guide shows the user interface instructions for the VT8350 Series Room Controller (RC) rmware revision 2.4 for users and
integrators.
User and Integrator Screens
The VT8350 Room Controller has dynamic screens that show adjustable parameters and read-only status information. Some
screens and parameters only show when a corresponding parameter is selected. Some screens only show on models with
onboard ZigBee, optional ZigBee add-on module (VCM8000), optional Wi-Fi module (VCM8002) or paired ZigBee wireless sensor
end devices (SED). The LUA selection on the Setup screen only shows if a LUA script is uploaded to the Room Controller.
See below legend screen details.

VT8350 [ User Interface Guide ]
Disclaimer
Standby screen: The Room Controller incorporates TFT-type LCD technology, and therefore,
necessary precautions are required to prevent the phenomenon of image retention (residual
image) from occurring.
Image retention may occur when a static image is displayed on the screen for a prolonged
period of time. This can cause a faint outline of the image to remain visible on the screen when
the screen is changed via the user menu, or a different image is uploaded and selected to be
displayed. To minimize and prevent image retention, it is recommended to select the Screen
Save setting on the Standby screen selection from the setup menu Display 1/2. This setting
switches the display during periods of inactivity from the Home Screen.
It is recommended to use a black or medium gray image, or one with light color contrasts as
the screen saver to prevent this phenomenon from occurring. If the display still exhibits this
phenomenon, loading an all-black or all-medium gray image as the screen saver and displaying it
for upwards of 5 hours continuously minimizes this effect.
NOTE: Avoid placing the Room Controller in poorly ventilated areas, or in areas that may
create excess heat around the display.

Setpoint Adjustment for Automatic Mode
In automatic mode, setpoint showing at the top of the set point bar located directly under the red line represents the actual
occupied cooling setpoint.
During occupied setpoints adjustment, large digits are temporarily used to display the occupied Cooling Setpoint or occupied
Heating Setpoint. The actual setpoint is dependent on the last effective demand (heating or cooling). The setpoint on top of the
blue line represents the actual occupied heating setpoint. The differential between the occupied heating and cooling setpoint is
dened by the minimum deadband conguration parameter.

NOTICE
UPGRADE OF ZIGBEE 2.4 TO 3.0
The upgrade from ZigBee 2.4 to 3.0 will not support the Green Power Sensor (SED-CO2-G-5045 or SED-TRH-G-5045). It will
therefore need to be recommissioned.
There is also a new “Security Levels” parameter for the Zigbee network (see page 20):
Low (default value) is fully backwards compatible with ZigBee Home Automation 1.2 devices, and therefore compatible with
all of our sensors.
Normal (needs to be selected by user) is only compatible with Green Power and ZigBee 3.0 (Leedarson sensors).
If the Normal Security Level is selected with old NYCE or Centralite sensors, they will be removed from the network.
Failure to follow these instructions can result in equipment being disconnected from the network.

ZIGBEE NETWORK 1/2
The ZigBee Network screen shows only in models with onboard ZigBee or optional ZigBee add-on module.
When creating a ZigBee network, there must be one and only one device with its Node Type set to Coordinator.
For a ZigBee network with a single Room Controller (RC), the RC is set as Coordinator to pair with the Sensor End Devices (SED).
Setting the RC back to Router will remove the paired SEDs.
For a ZigBee network with a Multi-Purpose Manager (MPM) paired to multiple RCs, the MPM is set as Coordinator and the RCs
are set as Router. The Coordinator MPM controls the pairing of the Router RCs to the SEDs
Note: Before pairing any ZigBee devices, the network must rst be created by the Coordinator.

Node type
Default: Router
Node Type
Sets device to act as Router or Coordinator in a network.
Coord.: Creates the network and manages the binding of wireless devices.
Router: Joins a network created by a coordinator (Coordinator permit join must
be set to ‘ON’).
Choices: Coord. or Router
PAN ID
Default value: 0
ZigBee Pan ID
Personal Area Network Identication that links specic Room Controllers to spe-
cic ZigBee coordinators. For every Room Controller reporting to a coordinator,
set the SAME PAN ID value both on the coordinator and the Room Controller.
Note: The default value of 0 is NOT a valid PAN ID and causes ZigBee to be
disabled.
Range: 1 to 65535
Channel
Default value: 10
ZigBee Channel
The channel (wireless frequency) on which the ZigBee network transmits and
receives data. The channel of the Coordinator must match that of the routers to
exchange data.
The default value of 10 is NOT a valid channel and causes ZigBee to be disabled.
The valid range of available channels is from 11 to 25.
Using channels 15, 20, and 25 is recommended. Channel 25 is considered as be-
ing the best one because it is furthest from the Wi-Fi channels.
Range: 10 to 25
