    (specific to UbiquiSTAT model). It contains many standard features from the TCS SZ series thermostats, as well as enhancements and new features. The UbiquiSTAT provides two network- ing options: TCSbus and BACnet.

  • Page 5: Mounting And Assembly

    MOUNTING AND ASSEMBLY 1 Mounting and Assembly The UbiquiSTAT™ is designed for wall mounting using two #6 sheet metal screws, either over a 2"x4" or 4"x4" junction box, or directly to the wall. For best results, the thermostat should be mounted on an interior wall that represents a normal room environment, at a height of approximately 48"...

    INITIAL SETUP These inputs must be configured using the corresponding mode objects in the internal BACnet explorer screen. See Sec- tion 4.5.2.6 for more information on the internal BACnet explorer screen. For an explanation of the features listed above, Section 3.5 Digital Outputs (DO) The various control outputs required by heat and cool stage control are mapped to physical terminal blocks on the con- troller via mechanical relays.

    USER INTERFACE Idle : Neither heating nor cooling is active. Warning : Heating or cooling lockout in effect. See Section 5 for more information on this feature. Disabled : The control is currently disabled and not heating or cooling. This is typically shown on startup during the power on delay, or when fan proving has failed.

Information on the system status screen is broken into three groups: • System (top) - State: The current system state. This is the same as the system state shown on the home screen. - Schedule: The currently active setpoint pair.

  • Page 19: Service Status

    Service Status is defined as a state of the controller or HVAC equipment that requires action by the end user to resolve. When a service status is active, a red badge is visible on the top of the home screen to the right of the TCS logo. Touching this badge presents the service status viewer, which shows all active service statuses and when they were detected.

Different from SZ Series Thermostats: Schedules no longer start and stop as they did on TCS SZ thermostats. Schedules now only transition from schedule to schedule.

Saturday and Sunday: The Unoccupied setpoints are in effect for the entire day. Setpoint Change Example: This schedule represents a business that opens at 10:00 AM and closes at 9:00 PM weekdays, and closes at 8:00 PM on weekends.

  • Page 26: Advanced Feature Summary

    ADVANCED FEATURE SUMMARY 4.5.2.12 Expert Settings By default, the UbiquiSTAT ships with two stages of heat and two stages of cool enabled (based on model feature avail- ability). Each stage may be independently disabled in order to prevent it from being considered by the control logic. This can be useful if, for example, the connected equipment does not support the stages, or to correct for a wiring error.

  • Page 27: Checkout And Troubleshooting

    CHECKOUT AND TROUBLESHOOTING • Fan Proving: The Fan Proving feature allows the controller to safely shut down the system in the case where the fan fails to operate correctly, avoiding damage to the heating or cooling units. The input to this feature is an external sensor that is connected to a Digital Input (DI) indicating that the fan is operating (closed) or not (open).

  • Page 28: Troubleshooting

    CHECKOUT AND TROUBLESHOOTING 6.2 Troubleshooting 6.2.1 No Display Remove cover and check for 24 VAC (22.8 to 27.6 VAC) on terminals labeled “+/- 24V”. Replace the cover and check for proper fit. Ensure the two internal board connectors snap in place. For more information on removing the cover, see Sec- tion 6.2.2 Fan Does Not Come On...

    Normally Closed. This causes the state of the relay to be closed (energized) when the status is “Off” and open (de-energized) when the status is “On”. The polarity can be changed using Ubiquity Cloud, TCS Insight or a third party BACnet configuration tool.

    Note: This method may be used to program all thermostats on a single network simultaneously. First, connect PC/laptop to the USB-to-RS-485 serial converter (TCS QD1010). Then wire the RS-485 network on the serial converter to the network on the UbiquiSTAT. The Communication Mode must be set to “TCSbus” on the UbiquiSTAT. The chosen baud rate in Insight must match the RS-485 network settings on the UbiquiSTAT.

  • Page 31: Backup/Restore

    USING INSIGHT WITH UBIQUISTAT STATs with earlier firmware may also be upgraded, but must be done so using third party BACnet tools. Call TCS techni- cal support for more information. • Firmware may be “downgraded” by choosing an earlier firmware version, but there is a risk of losing all programming, depending on the compatibility of the two versions.
