Product Description
The UbiquiSTAT product family is a feature rich, multi-purpose BACnet thermostat with a touchscreen interface. It can be
congured for conventional heating and cooling, heat pump, or modulating control applications; it has a number of heat/
cool setpoint groups and a number of output stages (specic 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.

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" from the oor. For best temperature measurement accuracy, avoid ar-
eas 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 wiring terminal blocks and relays and a front cover containing the touch-
screen and all other circuitry. Each base and cover pair is factory calibrated and serialized together. To remove the Ubiqu-
iSTAT cover, insert a small plastic pry tool or athead screwdriver between the front cover and base on the bottom of the
thermostat. Run the tool along the seam until the halves separate.
The following process ensures correct assembly when mating the front cover with the base. Check that no wiring inter-
feres with the cover, and no bare wires are exposed before assembly.

WIRING
2 Wiring
The UbiquiSTAT uses standard terminal designations for wiring. See the wiring diagrams on the following pages that cor-
respond 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 sens-
ing, discharge air temperature, outdoor air temperature or mixed air temperature. See Sections 3.1 and 3.2 for information
on conguring temperature inputs.
Use 18 AWG shielded twisted-pair wire grounded at the sensor mounting location. Sensor wiring runs of 250 feet are at-
tainable if properly shielded wire is used and the installation environment is free of electrical noise. Sensor wire should be
kept at least ve feet away from line voltage wiring. The UbiquiSTAT accepts 2-wire platinum 1000 Ohm RTD temperature
sensors. TCS provides a wide assortment of temperature sensors. Consult www.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 up to two current sensing inputs (AI1, AI2) congurable 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 ve
feet away from line voltage wiring. TCS provides a wide assortment of 4-20mA sensors and transmitters. Consult www.
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.
Caution: Do not connect to 120 VAC. Doing so will damage the UbiquiSTAT.
The UbiquiSTAT may be powered from the unit transformer, however if the UbiquiSTAT is wired for communications, a
dedicated power source (transformer) will avoid any potential ground loop issues between equipment transformers.
Several thermostats may be powered from the same dedicated transformer, provided that the transformer has sufcient
power and the power polarity is maintained.
Caution: When multiple TCS Basys Controls devices are using a single transformer, the polarity of the power wir-
ing must be maintained or damage will occur. All TCS devices are half-wave rectied 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.
