APPLICATIONS

The UbiquiSTAT product family is a feature rich, multi-purpose BACnet thermostat with a touchscreen interface. It can
be configured for conventional heating and cooling, heat pump, or modulating control applications, and has a number
of heat/cool setpoint groups, and a number of output stages (specific to UbiquiSTAT model). It contains many standard
features from the TCS SZ series thermostats, as well as enhancements and new features.
PRODUCT DESCRIPTION
MOUNTING AND ASSEMBLY
Product Description
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 five feet from the floor. For best temperature measurement accuracy,
avoid areas exposed to direct sunlight, unusual heat or cool sources, open doors and windows, unventilated locations,
and hot or cold air from diffusers. If using a remote room sensor, the sensor should be mounted in the same manner. The
thermostat should be mounted in an area which is accessible for adjusting settings.
The UbiquiSTAT™consists of a base (containing relays and terminal blocks) and a front cover (containing touchscreen
and all other circuitry). These two components are tethered together in order to prevent accidentally dropping of the front
cover and to prevent combining the base and front cover of two different UbiquiSTATs ™(each pair is factory calibrated
and serialized together).
When mating the front cover with the base, be sure to check that no wiring interferes with the cover, and no bare wires are
exposed. Check that the tether is clear of the snap, and is completely inside the enclosure.
To remove the UbiquiSTAT™cover, insert a small plastic pry tool between the front cover and base on the bottom of the
thermostat. Run the tool along the seam until the halves separate.

2 Wiring
The UbiquiSTAT™uses standard terminal designations for wiring. See figures 1a - 1d for the wiring diagram
corresponding to your UbiquiSTAT™model.
2.1 REMOTE TEMPERATURE SENSOR WIRING
There are three remote sensor inputs (T1, T2, T3) with a range of -40F to 160F. These can be used for remote room
sensing, discharge air temperature, outdoor air temperature, and mixed air temperature. See sections 3.1 and 3.2 for
information on configuring temperature inputs.
Use 18 AWG shielded twisted-pair wire grounded at the sensor mounting location. Sensor wiring runs of 250 feet are
attainable if properly shielded wire is used and the installation environment is free of electrical noise. Sensor wire should
be kept at least five feet away from line voltage wiring. The UbiquiSTAT™accepts 2-wire platinum RTD temperature
sensors. TCS provides a wide assortment of temperature sensors. Please consult tcsbasys.com for a full product listing.
When using remote sensors, the calibration may need to be adjusted. See section 4.5.2.2 for more information.
2.2 REMOTE ANALOG SENSOR WIRING
Depending on UbiquiSTAT model, there are uo to two current sensing inputs (AI1, AI2) configurable as 0-20mA or
4-20mA for connecting remote sensors. These inputs can be used for any current-based sensors such as CO² and
humidity.
Use 18 AWG shielded twisted-pair wire grounded at the sensor mounting location. Sensor wire should be kept at least
five feet away from line voltage wiring. TCS provides a wide assortment of 4-20mA sensors and transmitters. Please see
tcsbasys.com for a full product listing.
2.3 POWERING THE UBIQUISTAT™
The UbiquiSTAT is powered from 24 VAC +15% / -5% and draws up to 10 VA.
A dedicated power source (transformer) must be used when the UbiquiSTAT™is wired for communications to avoid
ground loop issues between equipment transformers. Several thermostats may be powered from the same transformer,
provided that the transformer has sufficient power and the power polarity is maintained.
Caution: Do not connect to 120 VAC. Doing so will damage the UbiquiSTAT™.
Caution: When multiple TCS Basys Controls devices are using a single transformer, the polarity of the power
wiring must be maintained or damage will occur. All TCS devices are half-wave rectified and have common
return paths.
When the UbiquiSTAT™is used as a stand-alone thermostat without communications, the equipment
transformer may be used to power it. To do this, install a jumper between the “R” and “+24” terminals. The “24-”
terminal must then be connected to the common side of the equipment transformer.
