Model Number Denitions – A Key to Understanding UbiquiSTAT Series Model Versions
TCS offers 16 different UbiquiSTAT versions based on four Models: the US4010, US4020, US4040, and US4050 (refer to
the UbiquiSTAT Product Data sheet for more information on the specic features of each Model).
Each UbiquiSTAT series is represented in the documentation by the following color icons:
Each Model in the series is available in several versions which can include wireless capability and an on-board
dehumidication sensor. These versions are identied in the color icons following the code below:

Introduction
Congratulations on choosing the UbiquiSTAT™ room controller! The Ubiquistat series of controllers are feature rich,
multifunction touchscreen devices providing extensive controls across a wide range of HVAC applications.
This manual covers all 16 variations of Ubiquistats including wired, wireless, and built-in dehumidication. It includes all
the information necessary to congure your UbiquiSTAT room controller, the communication network, and other devices
via the touchscreen.
Complete the conguration after installation (refer to the UbiquiSTAT Installation Manual and after completion of the
Startup Wizard (refer to the UbiquiSTAT Quick Setup Guide). Refer to the UbiquiSTAT BACnet Explorer Guide for advanced
information on using the built-in BACnet Explorer to edit the device’s BACnet programming objects directly.
Your conguration settings will be uploaded to Ubiquity Cloud the rst time you make a connection to the site.
Alternatively, you can skip conguring the UbiquiSTAT via the touchscreen and perform all congurations via Ubiquity
Cloud or TCS Insight software, which is available for download on the TCS website.
If you have any questions regarding your UbiquiSTAT room controller, contact TCS Technical Support at 800.288.9383,
ext. 2. Our Technical Support Department hours are Monday – Friday, 7:00 a.m. to 7:00 p.m. (CST).
Conguring Via the Touchscreen Interface
Home Screen
The Home screen displays at-a-glance system information and
basic user controls. The display automatically returns to the
Home screen and the display dims after 10 minutes of inactivity.
From the Home screen, you can congure many parameters for
the UbiquiSTAT. You can also change any initial settings you
made when following the UbiquiSTAT Quick Setup Guide.
For conguration options using the built-in BACnet Explorer, refer
to the UbiquiSTAT BACnet Explorer Guide.

Room Temperature and Setpoints
The room temperature is rounded to the nearest whole number. The active heat and cool setpoints will appear in place
of the room temperature when using the up/down arrows to adjust the temperature value or when touching the Room
Temperature numbers. The up/down arrows will change color to indicate the current setpoints are being overridden (blue
for cooler, orange for warmer). Touch the arrows to change the heating and cooling setpoints (User Setpoint Adjust)
together incrementally, to a maximum of +/– 5°F from the programmed setpoint.
Setpoint Override Indication: Warmer Setpoint Override Indication: Cooler
Digital Input Setpoint Setback Active Indicator
The Digital Input (DI) Setpoint Setback feature allows the user to adjust the effective heating and cooling setpoint values
based on the state of a DI. This allows the controller to increase the cooling setpoint and decrease the heating setpoint
by a predetermined amount and effectively create a setback response to an energy demand. The indicator becomes
visible then the DI Setpoint Setback feature is active. Touch the symbol to bring up a brief explanation of the feature.
Information Text Fields
The rst line displays outside air when a remote temperature sensor is connected It can also be congured to display
other system information. The second line displays the indoor relative humidity. 4X11 4X21 4X41 4X51

Fan Mode
Set/change the fan’s operation mode for occupied and unoccupied status by touching the FAN MODE button on the
SETTINGS screen. Select from the following modes:
• Auto: The fan runs only when there is a call for heating or cooling.
• On: The fan runs continuously.
• Auto + Recirc: The same as Auto but with additional run time, if necessary to satisfy minimum air circulation
requirements.
• Cool: The fan runs only when there is a call for cool (available only when thermostat type is conventional).

Occupancy Setpoints
Occupancy Setpoints work in conjunction with Schedule Settings to determine when heating and cooling takes place on a
given day. TCS recommends setting up occupancy setpoint parameters before creating occupancy schedules.
The UbiquiSTAT has ve heating and cooling occupancy setpoint pairs: four for occupied status, and one for unoccupied
status. Access the occupancy setpoint parameters by touching the SETPOINTS button on the SETTINGS screen.
Setpoint pairs are in effect when their corresponding schedules are active. To adjust an occupancy pair, select the
Occupancy Setpoint button you wish to adjust and use the up/down arrows to change its heating or cooling setpoints.
Occupancy Setpoints Screen Heating and Cooling Setpoints Example
NOTE: While the minimum “deadband” between heat and cool setpoints is set to one degree by default, TCS
recommends a deadband of at least two degrees for most conditions.
Occupancy Schedule Settings
NOTE: While all UbiquiSTAT models allow you to configure weekly schedules from the touchscreen, holiday schedule
settings are only available on wired models. To create holiday occupancy schedules on wireless models, use Ubiquity
Cloud or TCS Insight software, which is available for download on the TCS website.
Regardless of which schedule settings you use, the UbiquiSTAT will automatically default to Unoccupied mode and begin
using the Unoccupied setpoints at midnight each day. If no subsequent schedule changes are made for that day, the
UbiquiSTAT will remain in Unoccupied mode until the next schedule change.
If you need to create a schedule that requires an Occupied mode to begin at midnight, you must create a schedule change
for 12:00 AM in order to override the default.
Access the schedule settings by touching the SCHEDULE button on the SETTINGS screen, then selecting between weekly
and holiday schedules.(On wireless models, touching the SCHEDULE button on the SETTINGS screen will take you
directly to the WEEKLY SCHEDULES screen).
Schedule Settings Selection: Weekly or Holiday 401X 402X 404X 405X

Weekly Schedules
The UbiquiSTAT has a total of eight customizable schedule settings that can be used to create daily, weekly, or holiday
schedules. (By default, the UbiquiSTAT includes two schedule settings: an Occupied setting [A] at 8:00 AM Weekdays
setting, and an Unoccupied setting [B] at 5:00 PM Weekdays setting.) You can link schedules to the any of the ve
occupancy setpoints available. You can also combine schedules with different occupancy setpoint pairs to produce up to
eight schedule settings per day.
To create a schedule setting:

STEP 1 Touch the EDIT button on the Occupancy
Schedule Entries screen.
Edit Schedule Days Screen
STEP 2 Select the days of the week you wish to assign
the schedule to. (If desired, touch one of the
Quick Select buttons to quickly select the
respective days.) Touch the NEXT> button to
bring up the EDIT SCHEDULE screen.
STEP 3 The EDIT SCHEDULE screen will display any
previously created schedules assigned to the
selected days. From this screen you can select
a setpoint pair and assign it to the weekdays
you selected, or you can touch the NEW button
to create a new setpoint pair for the selected
days. You can also delete a previously selected
setpoint pair by pressing and holding the button
for three seconds.

Holiday Schedules
UbiquiSTATs can hold up to 30 holiday schedule settings. In most cases, holiday scheduling is managed via Ubiquity
Cloud. However, you can set up holiday schedules when using a wired, stand-alone UbquiSTAT that is not connected to
Ubiquity Cloud.
STEP 4 On the START TIME screen, use the up/down
arrows to select the time you want the new
schedule to start. Select the Occupancy Setpoint
pair you wish to assign. (OPTIONAL: you can edit
the setpoints for the setpoint group you selected,
but this will change the values wherever that
setpoint pair is assigned.) Touch DONE to save
your entry. On the EDIT SCHEDULE screen, touch
SAVE to save the changes.
NOTES: The first time you connect the UbiquiSTAT to
Ubiquity Cloud, the schedule settings will be automatically
uploaded to Ubiquity Cloud. After that, schedule settings
must be changed in Ubiquity Cloud. This prevents
unauthorized manual changes to the UbiquiSTAT.
Schedule periods stay in effect until the next schedule
period start time assigned to that day or until midnight,
at which point the UbiquiSTAT will revert to the default
Unoccupied setpoint pair
