Regulation (EC) No 1907/2006
According to Article 33 of Reach Regulation, be informed that the substances listed
below may be contained in these products above the threshold level of 0.1% by
weight of the listed article.
Important Safety Information and Installation Precautions
Read all instructions.
Failure to follow all instructions may result in equipment damage or a hazardous
condition. Read all instructions carefully before installing equipment.
When performing any work (installation, mounting, start-up), all manufacturer
instructions and in particular the TC300 Commercial Thermostat Mounting
Instructions (31-00642) are to be observed.
• TC300 Thermostat may be installed and mounted only by authorized and trained
personnel.
• It is recommended that devices be kept at room temperature for at least 24 hours
before applying power. This is to allow any condensation resulting from low
shipping/storage temperatures to evaporate.
• Do not open TC300 Thermostat, as it contains no user-serviceable parts inside!
• Investigated according to United States Standard UL- 60730-1, and UL60730-2-
9.
• Investigated according to Canadian National Standard(s) C22.2, No. 205-M1983
(CNL-listed).
• CE declarations according to LVD Directive 2014/35/EU and EMC Directive
2014/30/EU.
• Product standards are EN 60730-1 and EN 60730-2-9.
• TC300 Thermostat is Class B digital apparatus and complies with Canadian ICES-
003.
Local codes and practices
Always install equipment in accordance with the National Electric Code and in a
manner acceptable to the local authority that have jurisdiction.
Electrostatic sensitivity
This product and its components may be susceptible to electrostatic discharge
(ESD). Use appropriate ESD grounding techniques while handling the product.
When possible, always handle the product by its non-electrical components.

High voltage safety test
Experienced electricians, at first contact, always assume that hazardous voltages
may exist in any wiring system. A safety check using a known, reliable voltage
measurement or detection device should be made immediately before starting work
and when work resumes.
Lightning and high-voltage danger
Most electrical injuries involving low-voltage wiring result from sudden, unexpected
high voltages on normally low voltage wiring. Low voltage wiring can carry hazardous
high voltages under unsafe conditions. Never install or connect wiring or equipment
during electrical storms. Improperly protected wiring can carry a fatal lightning surge
for many miles. All outdoor wiring must be equipped with properly grounded and
listed signal circuit protectors, which must be installed in compliance with local,
applicable codes. Never install wiring or equipment while standing in water.
Wiring and equipment separations
All wiring and controllers must be installed to minimize the possibility of accidental
contact with other potentially hazardous and disruptive power and lighting wiring.
Never place 24 VAC or communications wiring near other bare power wires, lightning
rods, antennas, transformers, or steam or hot water pipes. Never place wire in any
conduit, box, channel, duct, or other enclosure containing power or lighting circuits
of any type. Always provide adequate separation of communications wiring and
other electrical wiring according to code. Keep wiring and controllers at least six feet
from large inductive loads (power distribution panels, lighting ballasts, motors, etc.).
Failure to follow these guidelines can introduce electrical interference and cause the
system to operate erratically.

Setting up BACnet MS/TP 13
Setting up BACnet MS/TP
The BACnet MS/TP network can be configured while setting up the thermostat.
Refer to the TC300 Commercial Thermostat User Guide - 31-00644 or follow the
steps below.
To connect thermostat via BACnet MS/TP
1. Swipe left from the Home page.
2. On the Quick access page, tap > Connection.
The Connection page appears.
Fig 1. BACnet MS/TP connection
3. Tap the BACnet MS/TP.
The BACnet MS/TP page appears.
Fig 2. BACnet MS/TP
4. Tap BACnet MS/TP and enable it.
The BACnet MS/TP configuration page appears.

Fig 3. BACnet MS/TP
5. The device automatically adapts to the baud rate of the MS/TP network. You can also
manually select the baud rate.
6. Enter a unique Device ID for the thermostat. It should be different from other TC300
thermostats.
7. Auto MAC addressing is enabled by default. The installer can also manually set a unique
MAC address for the TC300.
8. To do manual configuration, tap Manual.
A text box appears below to enter the MAC address.

12. Set the desired parameters and tap the back arrow button to navigate back to the
connection page.
Note: The TC300 will attempt to adapt to the baud rate of the MS/TP network in the first
four minutes after startup or when MS/TP is enabled. If the baud rate could not be
determined, for example, there is a single device on the network, then the TC300 will
choose the default baud rate of 76,800 Kbps. The installer can manually change the
baud rate to another value if desired.
