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 display. The up/down arrows will change color to indicate the current setpoints are being overridden
(blue for cooler, orange for warmer). The arrows change the heat and cool setpoints (User Setpoint Adjust) together
incrementally, to a deafault value of +/– 5°F from the programmed setpoint.
Setpoint Override Indication: Warmer Setpoint Override Indication: Cooler
DI Setpoint Setback Active Indicator
The Digital Input (DI) Setpoint Setback feature allows the user to adjust the effective heat and cool 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
The two line text eld displays outside air when a remote temperature sensor is connected to the UbiquiSTAT. It can also
be congured to display other system information.
Settings Screens
NOTE: Several of the settings described here were assigned during the initial setup of the UbiquiSTAT via the Startup
Wizard (refer to the UbiquiSTAT Quick Setup Guide). Follow these instructions if you need to change those settings.
Access to this menu can be controlled by the use of an access code, which can be assigned via the Startup Wizard (refer
to the UbiquiSTAT Quick Setup Guide) or via the Advanced section.
Touching the SETTINGS button at the bottom of the HOME screen brings up the Settings section, from which you can
congure all settings.

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 a total of 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 in the Settings display.
Setpoint pairs are in effect when their corresponding schedules are active. To adjust an occupancy pair, touch 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 five degrees by default, TCS
recommends a deadband of at least two degrees for most conditions.
Schedule Settings
Before creating occupancy schedules, make sure you have congured your desired occupancy setpoint pairs, as you must
assign a setpoint pair to each schedule setting. While all UbiquiSTAT models allow you to congure weekly schedules
from the touchscreen, holiday schedule settings are only available on wired models (4010, 4020, 4040, 4050). To create
holiday schedules on wireless models (4110, 4120, 4140, 4150), use Ubiquity Cloud or TCS Insight software.
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 in the Settings display, then selecting between weekly
and holiday schedules.(On wireless models, touching the SCHEDULE button in the Settings display will take you directly to
the Occupancy Schedule screen).
Schedule Settings Selection: Weekly or Holiday

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 [A] Occupied setting at 8:00 AM Weekdays
setting, and an Unoccupied setting 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.

Additional Congurations
This section describes how to congure many of the advanced options built into the UbiquiSTAT. Conguring these
advanced options calls for an understanding of the use of BACnet objects, which are accessible through the BACnet
Explorer (see ADVANCED 2/2 screen in the “Advanced Settings” on page 10 .) Each subsection describing the advanced
congurations includes the relevant BACnet object number(s). Refer to the UbiquiSTAT BACnet Explorer Guide for screen
identication and other information.
NOTE: Explanation of BACnet and BACnet objects is beyond the scope of this manual.
Adding Heating and/or Cooling Stages
By default, UbiquiSTATs ship with either one or two stages of heating and/or cooling enabled. However, the B/O and
TC relays can be congured as additional stages of heating and/or cooling when the UbiquiSTAT is congured as a
conventional thermostat. Reference BACnet IDs: MSV-316, MSV-317.
Scaling Analog Inputs ‘40 ‘50
The analog inputs (AI1, AI2) measure signals from sensors wired to the inputs. The scaling of those signals can be
independently adjusted to match the ranges of the sensors. Because the input signals are scalable, the UbiquiSTAT must
be congured to the sensors’ input ranges, signal minimums, and signal maximums:
• Input Range: Set the expected input range to 0 – 20mA or 4 – 20mA. Reference BACnet IDs: MSV-170, AV-171
• Scaled Minimum: Denes the sensor value when its signal is at the minimum range (0 or 4mA). Reference BACnet
IDs: AV-161, AV-163
• Scaled Maximum: Denes the sensor value when its signal is at the maximum range (20mA). Reference BACnet IDs:
AV-162, AV-164
In addition, there are four read-only analog BACnet objects which display the raw readings and the engineering scaled
values. Reference BACnet IDs: AI-151, AI-152, AV-181, AV-182.
Setpoint Setback
The Setpoint Setback feature allows the user to increase the cool setpoint and decrease the heat setpoint by a
predetermined amount based on the state of a Digital Input (DI). Reference BACnet ID: AV-1254.
Economizer ‘40 ‘50
The Economizer (also called “free cooling”) uses outdoor air for cooling, when appropriate, to reduce the need for
mechanical cooling. Reference primary BACnet IDs: AO-200, AV-240; MSV-210, MSV-220, MSV-230, AO-201, AV-241,
MSV-211, MSV-221, MSV-231, AV-1500, MSV-1501, MSV-1511, AV-1512. Reference secondary BACnet IDs relevant to your
application: AV-1510, AV-1513, AV-1514, AV-1515, BV-1516, BV-1517.
Commissioning the UbiquiSTAT
When commissioning the UbiquiSTAT for the rst time, do the following:
• Verify all wiring connections to the mounting plate are secure, with no loose strands. Check all screws for tightness
• Ensure the front cover is lined up properly and snapped into place
• Ensure the UbiquiSTAT is connected to an appropriate power source. The screen should be lit
• Ensure you have completed all programming correctly
• Navigate to the System Test Mode (refer to “System Test Mode” on page 16) and ensure the heating and cooling
modes are functioning properly by turning on and off all outputs
• Verify and test modulating outputs changing and then resetting the milliamp output (refer to “Scaling Analog Inputs ”
on page 20)
• If the UbiquiSTAT is to be networked, verify it has the proper network address, baud rate, mode, and device ID. If the
network is active, conrm the RS-485 link status is “Connected”: (refer to “Network Screen” on page 18)
