Introduction

Congratulations on choosing the UbiquiSTAT™ room controller! The UbiqiSTAT series of controllers are feature rich, 

multifunction touchscreen devices providing extensive controls across a wide range of HVAC applications. 
This manual includes all the information necessary to install and wire your UbiquiSTAT room controller. It includes a 

breakdown of the input and output wiring for each type of connection. 
After installing your UbiquiSTAT, refer to the 

UbiquiSTAT Quick Setup Guide

 for instructions on the basic setup of the 

device. Refer to the 

UbiquiSTAT Configuration Guide

 for instructions on configuring the device, the communications 

network and other devices connected to this controller. 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.
If you have any questions regarding your UbiquiSTAT room controller, do not hesitate to 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).

Opening the UbiquiSTAT

The UbiquiSTAT consists of a base containing wiring terminal blocks and relays, and a front cover containing the 

touchscreen and all other circuitry. It is shipped unassembled. Each base and cover pair are serialized together; if you are 

installing multiple UbiquiSTATs, do 

NOT

 mix and match bases and covers. 

To remove the UbiquiSTAT cover once assembled, insert a small plastic pry tool or flathead screwdriver between the front 

cover and base on the bottom of the thermostat. Carefully run the tool along the seam until the halves separate. 

Mounting the UbiquiSTAT

Mount the base of your UbiquiSTAT room controller on a vertical wall using two #6 sheet metal screws, either over a 2" 

x 4" or 4" x 4" junction box, or directly to the wall. For best results, select an interior wall that represents a normal room 

environment, at a height of about 48" from the floor. Mount the unit in a location which is accessible for adjusting settings.

For best temperature measurement accuracy, avoid areas that are exposed to direct sunlight, unusual heating or cooling 

sources, open doors and windows, unventilated locations, and hot or cold air from diffusers. If you are using a remote 

room sensor, mount it in the same manner. 

Powering the UbiquiSTAT

The UbiquiSTAT is powered from 24 VAC +15%/–5% and draws up to 10VA. If wiring for communications, you must use 

dedicated power (transformer) to the unit. Several TCS controllers may be powered from the same transformer, provided 

the transformer has sufficient power and you maintain proper polarity. While the UbiquiSTAT may be powered from the 

HVAC unit controller, using a dedicated power source will avoid any potential ground loop issues between equipment 

transformers. 

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” (Packaged Unit Terminations) and “+24” (Power) terminals. 

The “–24” (Power) terminal must then be connected to the common side of the equipment transformer.
