TB7300 Series Communicating
Fan Coil Thermostats
24 VAC/FOR COMMERCIAL AND LODGING HVAC
APPLICATIONS
APPLICATION
The TB7300 PI thermostat family is specifically designed for
fan coil control. The TB7300 Series are communicating
thermostats with models available in BACnet® MS/TP and
ZigBee® wireless mesh protocols and can be easily
integrated into a WEBs-AX building automation system based
on the NiagaraAX® platform.
Thermostats equipped with an occupancy sensor cover
provide advanced active occupancy logic, which will
automatically switch occupancy levels from Occupied to
Stand-By and Unoccupied as required by local activity being
present or not. This advanced occupancy functionality
provides advantageous energy savings during occupied
hours without sacrificing occupant comfort. All thermostats
are PIR ready and can be ordered with or without Honeywell
occupancy sensor. The occupancy sensor cover is available
to order separately if a PIR is needed at a later time.
FEATURES
• Available in BACnet MS/TP and Zigbee wireless protocols
• Backlit LCD display with dedicated function menu keys for simple operation
• Internal humidity sensing for increased occupant comfort through dehumidification on some models
• Fully integrated advanced occupancy functionality with a PIR cover provides energy savings opportunity on
select models; all other models are PIR ready and can have an optional occupancy sensor cover added
• Configurable sequences of operation
• Configurable fan button allows thermostat to meet more applications with a single model
• Password protection to minimize parameter tampering
• Six levels of keypad lockout to limit access to change user parameters such as setpoints, system mode, etc.
• Auto Fan speed mode increases occupant comfort in cooling mode by reducing humidity and reduces fan
noise
• Available for 24 Vac on/off, floating or analog control meets advanced applications requirements
• Three inputs for monitoring and other advanced functions
• SPST auxiliary output that can be used for lighting or auxiliary reheat
• All wiring connections are made to removable terminal blocks simplifying installation

needed.
More Information
We recommend downloading the appropriate integration reference document (wireless or BACnet) and if installing
thermostats with occupancy sensor covers, then also downloading the PIR Application Guide before you begin
installation. All documentation is available on http://customer.honeywell.com.
— BACnet Integration Manual for TB7200 and TB7300 Series Thermostats (Form No. 63-4524)
— Wireless Installation and Integration Reference Guide for TB7200, TB7300, and TB7600 Thermostats
(Form No. 63-4522)
— PIR Application Guide for TB7200 and TB7300 Series Thermostats (Form No. 63-4526)

INSTALLATION AND WIRING
Mounting Locations
• Do not install on an outside wall.
• Must be installed away from any heat source.
• Should not be installed near an air discharge grill.
• Should not be mounted in direct sun radiation.
• Nothing must restrain vertical air circulation to the thermostat.
• Wall surface must be flat and clean.
IMPORTANT
• If replacing an old thermostat, label the wires before removal of the old thermostat.
CAUTION
• Electronic controls are static sensitive devices. Discharge yourself properly before manipulation and installing
the thermostat.
• Short circuit or wrong wiring may permanently damage the thermostat or the equipment.
• Anti-short cycling can be set to 0 minutes for equipment that has an anti-cycling timer. Do not set to 0 unless
the equipment has internal anti-cycling timer or damage to equipment can occur.
• All TB7300 Series thermostats are to be used only as operating controls. Whenever a control failure could
lead to personal injury and/or loss of property, it becomes the responsibility of the user to add safety devices
and/or alarm system to protect against such catastrophic failures.

THERMOSTAT USER INTERFACE
The thermostat features a two-line, eight-character display. There is a low level backlight level that is always active and
can only be seen at night. To turn on the back light to high level, press any key on the front panel. The back lit display
will return to low level when the thermostat is left unattended for 45 seconds
When left unattended, the thermostat has an auto scrolling display that shows the actual status of the system. Use the
MenuScro in the configuration menu to lockout the scrolling display and to only present the room temperature and
conditional outdoor temperature to the user. With this option enabled, no local status is given on the system mode or
occupancy.
Each item is scrolled one by one with the back lighting in low level mode. Pressing any key will cause the back light to
come on to high level. When left unattended for 10 seconds after changes are made, the display will resume automatic
status display scrolling.
Table 3. Sequence and possible display options for the auto-scroll display
* Network value only
**If humidity display is enabled
***If humidity display is not enabled
% RH DISPLAY IS CONDITIONAL TO:
• Models with RH sensor built in.
• Display function can be enabled with RH display parameter. Displayed range is 10 to 90% RH.
OUTDOOR AIR TEMPERATURE
• Display is only enabled when outdoor air temperature network variable is received.
OCCUPANCY STATUS
• Occupied, Stand-By, Unoccupied and Override status are displayed on the scrolling display.
ALARMS
• If alarms are detected, they will automatically be displayed at the end of the status display scroll.
• During an alarm message display, the backlit screen will light up at the same time as the message and shut off
