Delta Network Thermostat: BACstat II
DNT-T103 (Rev 4.1)
Document Edition 1.9
Product Description
The DNT-T103 is an intelligent room thermostat with a custom 3-
value, 96 segment LCD display. The DNT-T103 can communicate on
a BACnet MS/TP network or on Delta’s proprietary LINKnet network.
The DNT-T103 can display a wide-range of digital or analog values,
including setpoints, temperature, air flow, heating and cooling status,
fan speed, valve and damper position, and more.
When connected on a BACnet MS/TP network the DNT-T103
functions as an independent BACnet thermostat. When connected to a
controller, on a LINKnet network, it provides a programmable remote
sensor and expanded I/O capabilities. This version’s firmware can be
flash loaded over the network, and has a termination resistor that is
jumper selectable.

The binary triac outputs can be selected to use either an internal or
external power source by placing the two jumpers in the correct locations.
The diagram to the left shows the factory default selection of Internal
Power Source.
Internal 24 VAC Power is provided internally from within the board
right to the output terminals. No external transformer is
required. The associated triac outputs are “hot” contacts. Note
that the power supply should be sized appropriately to handle
the additional loading.
External Power needs to be provided externally to the board from a
nearby transformer appropriately connected to the output wiring.
The associated triac outputs are
not
“hot” contacts, except by
means of the external transformer.
NOTE: Triacs are solid-state components that are only appropriate for
switching 24 VAC. They cannot be used to switch DC voltage. They also
have a small leakage current and may not be appropriate for certain “dry
contact” applications.

Wiring Diagram
Warning:
The network shield and any other bare wires should be bent back and taped to ensure that they
do not come into contact with the board electronics and cause a short. Otherwise you run the
risk of damaging the BACstat.

Delta Controls
Notes:
1. Ensure you use the recommended balanced cable for the network and follow and follow the documented
procedures within
Delta Controls Wiring and Installation Guidelines
for MS/TP or LINKnet networks.
2. Do
not
use 4-wire multi-conductor cable for network and power, as it will not meet the balanced cable
requirements for the MS/TP or LINKnet networks. Use two separate cables: one for the network and the
other for power.
3. Do not terminate the network shield on the BACstats, but ensure shield conductivity is maintained along the
network from end-to-end with wire nuts as necessary.
4. If the same power source is used for more than one device, ensure that the transformer is properly sized for the
rated VA and that the same polarity is observed from device to device.
Power
The DNT-T103 requires a 24V AC Class 2 power supply. The VA requirements vary depending on the
output configuration as follows:
41 VA maximum (with internally powered triacs at full load)
3 VA (with triacs externally powered)
More than one device – not including DCUs or V2 products – may be connected to the same transformer, if
the transformer is properly sized (including line losses), and the polarity is observed between controllers (in
regards to 24~ and GND). The transformer must
ONLY
be used to provide power to other MS/TP
or
LINKnet devices and field devices powered through its outputs. Auxiliary field devices (i.e., 4-20 mA
devices) that don’t use ½ wave rectification must be powered separately.
For more information refer to the
Delta Controls Wiring and Installation Guidelines
.
Network & Cabling Requirements
Adhere to the following network and cabling requirements to ensure network stability and reliable communications,
particularly at high speeds on the RS-485 MS/TP or LINKnet networks.
Item
Description
Cabling
For MS/TP and LINKnet networks it is recommended that you use network cabling that
matches the following specifications:
•
Balanced 100 to 120
Ω
nominal impedance Twisted Shielded Pair (TSP) Cable
•
Nominal capacitance of 16 PF/FT or lower
•
Nominal velocity of propagation of 66% or higher
Topology
For MS/TP and LINKnet networks, ensure the cable is installed as a
daisy-chain
from one
device to the next.
Max. Nodes
•
MS/TP: The maximum number of devices per MS/TP network without any repeaters is
50
.
•
LINKnet: Up to a maximum of 12 Devices (depending on the controller), only two of
which can be DNT or DFM devices. (Refer to the Appendix called
Working with MS/TP
and LINKnet
in the
Technical Reference Manual
for more information.)
Termination
•
MS/TP: A termination resistor must be jumper selected at each end of each MS/TP network

Boards
segment. Ensure you do not overlook this in laying out your network architecture.
•
LINKnet: Jumper select a termination resistor on each end of the network when there
are more than 2 nodes. Termination resistors do not need to be installed for one or two
nodes.
Repeater
•
MS/TP: A repeater (RPT-768) is not necessary unless more than 50 nodes will be installed
on a network
or
you need to extend the network beyond 4000 ft (1220 m).
•
LINKnet: Repeaters should not be necessary. Ensure the maximum distance is no
more than 1000 ft (300 m).

Delta Controls Wiring and Installation Guidelines

Network Topology
1. BACstats Configured as MS/TP Subnet Devices
With V3.21 firmware or higher, one possible MS/TP network architecture has the MS/TP devices configured as
Subnet devices, which allows BACstats to reside on the MS/TP network with other Subnet devices. Note that
V3.21 requires a DCU, while V3.22 or higher may use any System Controller instead.
2. BACstats Configured as LINKnet Devices
The BACstat may reside on LINKnet instead of MS/TP. However, this requires a controller that supports a
LINKnet network for I/O expansion. The maximum LINKnet devices with or without I/O depends on the
controller. All built-in applications must be disabled, but the I/O may be muxed (with V3.22 firmware).

2. Ensure the cable is installed as a daisy-
chain from one device to the next. (1000'
or 300m maximum).
3. *Ensure you jumper select a MS/TP
termination resistor when you have more
than 1 or 2 devices.
4. Depending on the controller, up to 12
devices are supported on a LINKnet
network, with limitations on how many of
these may have I/O. (Refer to the
Technical Reference Manual.)

Cautions and Warnings
The DNT-T103 BACstat II is an electrostatically sensitive device. An ESD protection (ground
strap) should be unnecessary if sufficient care is taken in handling because the electronics are
contained within the product housing.
UL 864 Specific Considerations
•
Use the transformer by Core Components Inc., Model No. 120-024-100-2TF-CB to power the device.
•
Use only UL Listed Class 2 Power Supplies for auxiliary field devices.
