Crestron CHV-TSTATEX-FCU infiNET EX™ Thermostat (Fan Coil Unit)
infiNET EX™ Thermostat
(Fan Coil Unit):
CHV-TSTATEX-FCU
Introduction
The CHV-TSTATEX-FCU is a wireless thermostat featuring infiNET EX™
technology. The CHV-TSTATEX-FCU installs just like a conventional thermostat
because no extra wires are needed to connect to the control system. Although
functional as a standalone thermostat, the CHV-TSTATEX-FCU delivers enhanced
functionality as part of a complete Crestron®automation system. Integrating HVAC
with a Crestron system can help lower energy bills and increase user friendliness.
The CHV-TSTATEX-FCU is designed for fan coil unit HVAC systems. The large
backlit LCD display provides a clear view of temperature, set point, system mode,
fan mode, system status, and setup functions. Climate control features include
separate heating and cooling set points, and adjustable anticipators to prevent
overshooting the desired temperature. Continuous fan operation can be selected
when needed for increased circulation.
Features and Functions

infiNET EX™ Thermostat (Fan Coil Unit) Crestron CHV-TSTATEX-FCU
Fan Coil Unit Support
The CHV-TSTATEX-FCU model of the infiNET EX™ thermostat provides the
functionality of controlling fan coil units*. Aesthetically identical to the base model,
the CHV-TSTATEX-FCU has custom firmware, display programming and terminal
labels designed for 3-speed fan applications. The CHV-TSTATEX-FCU supports
on/off control of the valves and the fan in 4-pipe fan coil applications, eliminating
the need for an additional device dedicated to controlling the fan coil unit itself.
infiNET EX Communications
Built on steadfast infiNET EX technology, infiNET EX is the new standard in 2-way
wireless connectivity that can handle installations in even the most urban settings.
The redundant nature of its mesh networking technology means that a command will
never be missed, resulting in faultless operation - something that is of the utmost
importance when it comes to HVAC control and home automation. The
CHV-TSTATEX-FCU harnesses this cutting edge wireless connectivity which
affords it a level of robustness and dependability above other solutions.
Automation System Integration
The wireless connection to the control system allows the functions of the
CHV-TSTATEX-FCU to be controlled from touch screens, keypads, wireless
remotes, computers, or even a mobile device. It supports unlimited flexibility for
remote control, scheduling, and integration with other devices and systems.
However, in the event that communication with the control system is disrupted for
any reason, the CHV-TSTATEX-FCU will remain operable to control the HVAC
system.
Easy Installation
System design and installation using infiNET EX thermostats could not be easier.
Since no control wires are required, the CHV-TSTATEX-FCU can be installed just
like any conventional thermostat.
To simplify installation, physical switches are provided for the most critical
configuration options, including heat/cool type, heat pump behavior, power settings,
number of heating/cooling stages, and fan options. These settings allow HVAC
contractors to install and test the thermostats prior to the appearance of a Crestron
system integrator.
An infiNET EX gateway such as the CEN-RFGW-EX or MC3 is needed for
communications. Setting the ID of each device employs the same convention as
Crestron's familiar TSID method, and each device is programmable using Crestron
SIMPL Windows, SystemBuilder™ or D3Pro®software just like any wired Cresnet®
device. Even firmware updates are performed over the wireless network.
No further action is required to configure the infiNET EX network. Each device
assigned to a common gateway automatically behaves as a wireless expander2for
any other devices within range (approximately 150 feet (~46 meters) indoors), and
additional expanders may be added if necessary. The infiNET EX gateway monitors
each device on the network at all times, ignoring any other 2.4 GHz signals. It
reconfigures the entire network automatically in response to new sources of
interference and other changes in RF conditions.
1. Four pipe fan coil units are supported.
2. CHV-TSTATEX-FCU must be powered by a 24 volt source to enable repeater functionality.

DIP Switch Setup
The following describes the CHV-TSTATEX-FCU DIP switch settings.
1. Install two AA batteries (supplied) in the battery compartment.
2. Locate the DIP switches inside the unit and configure the following
parameters:
DIP Switch Settings

# DESCRIPTION ON OFF
4 Heat mode Enabled Disabled
3 Cool Mode Enabled Disabled
2 Auto mode Enabled Disabled
1 Auto mode behavior Single setpoint Dual setpoint
By default, the CHV-TSTATEX-FCU is configured to be powered by two AA
alkaline batteries. To extend battery life, the device also receives power from the
HVAC system by drawing a small amount of current through the heat or cool
terminals. This is known as Steal Power mode.
To enable this feature, locate the POWER slide switch inside the unit and slide it to
STEAL (This is the default factory setting on the CHV-TSTATEX-FCU).
POWER Slide Switch
NOTE: Steal Power mode will not draw enough current to cause the external heat
or cool relays to close. More specifically, when the unit is not making a call for heat,
it will draw power through the R and W terminals. When the unit is making a call for
heat, it will draw power through the R and Y terminals. (This will not work if the
thermostat has been wired for a cool only application.). The
CHV-TSTATEX-FCU must be wired for heat control in order to take advantage of
Steal Power mode.
NOTE: In Steal Power mode, even when an auxiliary power source is available, the
unit will continue to enter a communications sleep state, waking every 30 seconds or
10 •infiNET EX™ Thermostat (Fan Coil Unit): CHV-TSTATEX-FCU Operations & Installation Guide – DOC. 7206A

Crestron CHV-TSTATEX-FCU infiNET EX™ Thermostat (Fan Coil Unit)
one minute (based on the infiNET EX Sleep Time setting) to exchange data with the
control system. Refer to “Remote Operation” on page 22 for details.
NOTE: Steal Power mode may cause problems with some types of HVAC systems,
such as indicating a false heat or cool call. If this occurs, do not use Steal Power
mode.
If the thermostat will be wired so that 24 Volts AC will always be present on the 24C
terminal, slide the POWER switch to 24VAC. No batteries will be required in this
mode (except during initial setup).
NOTE: When the unit detects 24 VAC is present, it will no longer “sleep”, meaning
it will offer real-time communication with the control system.
NOTE: When the unit is powered from a constant 24 VAC supply, there may be a
slight discrepancy between the ambient temperature displayed on the thermostat and
the actual room temperature. This discrepancy will also be seen when switching from
STEAL to 24VAC. This is normal and the discrepancy will disappear within
approximately 10 minutes.
Wiring the CHV-TSTATEX-FCU to the HVAC
System
Make the necessary connections as called out in the illustrations that follow. A flat
head screwdriver (not supplied) is required to attach the control wires from the
HVAC system. Apply power after all connections have been made.
The illustrations on the following pages show examples for connection to various
types of HVAC systems. If your system does not match any of the systems described
below, contact Crestron Technical Support for assistance.
