Heat/Cool Thermostat
The CHV-TSTATEX is designed for heating and cooling control of baseboard,
forced air, heat pump and dual-fuel heat pump HVAC systems. The large backlit
LCD display provides a clear view of current temperature, setpoint, system mode,
fan mode, system status and setup functions. Climate-control features include
separate heat and cool setpoints and adjustable anticipators to prevent overshooting
the desired temperature. Continuous fan operation can be selected when needed for
increased circulation.
infiNET EX Communications
Built on steadfast infiNET 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 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 to be controlled from touch screen s, 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 will remain operable to control the HVAC system.
Easy Installation
System design and installation using infiNET EX thermostats could not be easier.
Because no control wires are required, the CHV-TSTATEX 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 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 D3Pr o
device. Even firmware updates are performed over the wireless network.

By default, the CHV-TSTATEX 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).
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 RH and W terminals. When the unit is making a call
for heat, it will draw power through the RC and Y terminals. (This will not work if
the thermostat has been wired for a cool only application.). The CHV-TSTATEX
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
one minute (based on the infiNET EX Sleep Time setting) to exchange data with the
control system. Refer to “Remote Operation” on page 26 for details.
10 • infiNET EX™ Thermostat: CHV-TSTATEX Operations & Installation Guide – DOC. 6989A
Crestron CHV-TSTATEX infiNET EX™ Thermostat
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 DIP 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 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.

Crestron CHV-TSTATEX infiNET EX™ Thermostat
Operation
System Mode
The MODE button on the CHV-TSTATEX will cycle the unit through all available
system modes in the following order: Off, Heat, Emergency Heat (for heat pump and
dual-fuel systems), Cool and Auto (if enabled in Setup).
The system mode will change upon release of the MODE button and the selected
mode will become operational five seconds after the mode has been entered.
Off Mode
In Off mode, all HVAC systems are disabled.
Heat Mode
In Heat mode, the thermostat uses the heating system to maintain the setpoint
temperature.
AUX Heat Mode
In Aux Heat mode, the thermostat uses only the auxiliary heat output on heat pump
or dual-fuel systems to maintain the setpoint temperature.
NOTE: Aux Heat mode can only be accessed when heat/cool type has been set to
“Heat pump” or “Dual-Fuel Heat pump”. This setting can be useful when the heat
pump is being serviced or when there is an unexpected problem with it. The display
will flash the “flame” icon when the system is in Aux Heat mode.
Cool Mode
In Cool mode, the thermostat uses the cooling system to maintain the setpoint
temperature.
Auto Mode
In Auto mode, the thermostat allows the system to switch between Heat and Cool
automatically as needed to maintain the setpoint temperature. By default, the
CHV-TSTATEX has been configured with Auto mode disabled, meaning it is not
available from the thermostat itself or via another interface such as a touch screen.
In order to enable Auto mode, you must enter Setup mode and change the “AU”
setting from “--” to either “d” (dual setpoint) or “S” (single setpoint). Refer to “Setup
Mode” which starts on page 19 for details.
Once Auto mode has been enabled, you can access it from the CHV-TSTATEX
controls as follows:
1. Press the MODE button until both the flame
appear in the display. This indicates Auto mode is now active.
2. Use the

The flashing icon will time out after five seconds of no button activity.
b. In single setpoint Auto mode, use the buttons to adjust the setpoint as
usual.
Dual Setpoint Auto Mode (“AU” = “d” in Setup Mode)
In dual setpoint Auto mode, separate heat and cool setpoints are used. When the
ambient temperature drops below the heat setpoint, the unit will call for heat to
maintain the heat setpoint. When the ambient temperature rises above the heat
setpoint, the unit will not call for cooling until the temperature exceeds the cool
setpoint. When the ambient temperature drops below the cool setpoint, the unit will
not call for heating until the temperature is below the heat setpoint.
When dual setpoint Auto mode has been enabled, the Auto Dead Band is used to
maintain a minimum separation between the heat and cool setpoints. If this
separation is violated by a setpoint adjustment, the other setpoint will be
automatically adjusted.
and buttons will adjust that setpoint.
For example, if the heat setpoint is at 68 degrees, the cool setpoint is at 72 degrees
and the Auto Dead Band is set to 4 degrees, if you lower the cool setpoint to 71
degrees, the heat setpoint will automatically be adjusted to 67 degrees to maintain
the 4 degree Auto Dead Band separation.
In dual setpoint Auto mode, the CHV-TSTATEX display will indicate whichever
setpoint is closer to the ambient temperature. Both the heat and cool setpoints can be
viewed simultaneously using a touch screen.
Single Setpoint Auto Mode (“AU” = “S” in Setup Mode)
In single setpoint Auto mode, a single setpoint is used for regulation at all times,
regardless of whether the system is heating or cooling. The Auto Dead Band (“db”)
setup parameter is used to determine when to switch between heating and cooling.
For example, if the setpoint is at 70 degrees and the Auto Dead Band is set to 2
degrees, if the system is cooling, it will not start heating until the ambient
temperature drops below 68 degrees (setpoint – Auto Dead Band). Once the unit has
switched to heating, it will not resume cooling until the ambient temperature rises
above 72 degrees (setpoint + Auto Dead Band).
A larger value for the Auto Dead Band setting will result in less cycling between
heating and cooling but can result in large temperature swings during the course of
the day. Smaller values for the Auto Dead Band setting will result in tighter
temperature regulation but more frequent cycling between heating and cooling.
NOTE: When using a single setpoint, the CHV-TSTATEX has a 20-minute change
limiter to prevent system toggling.
Fan
The FAN button toggles the fan setting between fan AUTO and fan ON. When set to
AUTO, a fan call will be made whenever the system makes a cool call or when the
system makes a heat call or auxiliary heat call (if the DIP switch is set to “Enabled”).
When set to ON the fan will always run.

Crestron CHV-TSTATEX infiNET EX™ Thermostat
Setpoints
The setpoint is the user selectable temperature you want the system to maintain.
The
and buttons will change the current setpoint by one degree F or C (if
Temperature Scale is set to “F” or “C1”) or by one half degree C (if Temperature
Scale is set to “C2”).
NOTE: While the setpoint is being adjusted, if it is set to a half-degree increment,
the integer portion of the number will be displayed and will alternate with “_5” every
quarter second for a period of four seconds after the last adjustment. After four
seconds, only the integer portion of the number will be displayed.
If the or button is held down for two seconds, the unit will enter an auto-repeat
state and the setpoint will adjust rapidly until the button is released or until the upper
(or lower) limit is reached.
Some users will want to have setpoints change automatically based on the day of the
week and the time of day. For example, in the winter they may want to lower the
heat setpoint while they sleep to lower heating costs. To accommodate this, the
CHV-TSTATEX provides a “Scheduled Heat Setpoint” and a “Scheduled Cool
Setpoint” which can be specified by the control system program. This is handled
automatically by the “Crestron CHV-TSTATEX w/5-2 Scheduler” module provided
with the Crestron Database. Refer to the SIMPL Windows help file for details.
For dual setpoint operation, refer to “Auto Mode” which starts on page 23.
Hold
Hold allows the user to adjust the setpoint and will maintain that setpoint until the
unit is taken out of Hold. This means that any change to the scheduled heat or cool
setpoint that occurs while in Hold will be ignored until the unit is taken out of Hold.
Pressing the MODE and FAN buttons simultaneously will cause the unit to enter
Hold if Hold is not yet active and the system mode is Heat, Emergency Heat or Cool.
Pressing the MODE and FAN buttons simultaneously when Hold is active will
cause the unit to exit from Hold and recall either the scheduled heat setpoint or
scheduled cool setpoint as appropriate to the system mode.
If the system is in single setpoint Auto mode, exiting from Hold will recall the
scheduled auto setpoint. If the system is in dual setpoint Auto mode, upon exiting
from Hold, the auto cool setpoint becomes the scheduled cool setpoint and the auto
heat setpoint becomes the scheduled heat setpoint.
Pressing the MODE and FAN buttons simultaneously when the system mode is Off
will have no effect.
When Hold is active, the unit will continue to adjust the current setpoint when the
or
buttons are pressed. The unit will also continue to adjust the current setpoint
when the setp oint signal from the control system changes.
When the system mode changes to Heat or Emergency Heat, the current setpoint will
be set to the scheduled heat setpoint.
When the system mode changes to Cool, the current setpoint will be set to the
scheduled cool setpoint.

infiNET EX™ Thermostat Crestron CHV-TSTATEX
Remote Operation
As an infiNET EX device, the CHV-TSTATEX can be controlled remotely via a
Crestron control system. Most often, control of the thermostat will be achieved via a
touch screen or Web-based graphical interfa ce. In order to extend battery life, the
thermostat will only communicate with the control system once every 30 seconds or
one minute, based on the infiNET EX Sleep Time setting. Because of this, there will
be a noticeable delay between the time a button is pressed on a touch screen and
when the thermostat reacts to the command. To account for this, the
CHV-TSTATEX modules written by Crestron and provided in the Crestron Database
will mimic the feedback from the thermostat so that the user will see an immediate
response on the touch screen.
Likewise, pressing a local button on the thermostat (for example, setpoint raise or
lower) will not cause an immediate change to the corresponding display on a touch
screen. Instead, the thermostat will wake up shortly after the last button press to send
its updated status to the control system.
If the thermostat is wired to have the optional 24 VAC at the 24C terminal and the
power switch is set for 24V, there will not be a delay in feedback.

Uploading and Upgrading
Crestron recommends using the latest programming software and that each device
contains the latest firmware to take advantage of the most recently released features.
However, before attempting to upload or upgrade it is necessary to establish
communication. Once communication has been esta bl i shed, files (for example,
programs or firmware) can be transferred to the control system (and/or device).
Finally, program checks can be performed (such as changing the device ID or
creating an IP table) to ensure proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the CHV-TSTATEX; refer to the
Crestron Toolbox help file for details. There is a single method of communication:
indirect communication.
Indirect Communication
CEN-RFGW-EX
LAN
Control System
The CHV-TSTATEX connects to the CEN-RFGW-EX (gateway), which connects to
control system via Ethernet.
Establish communications between the PC and the control system as described in the

Appendix: About Heat Pumps
A heat pump extracts available heat from one area and transfers it to another. Even
cold air contains some heat and heat pumps can extract heat from the outside air on a
cold day and transfer it indoors to maintain a comfortable temperature. A heat pump
also works in reverse during the summer, extracting heat from indoors and
transferring it outdoors.
In the heating mode, the efficiency of a heat pump decreases as the outdoor air
temperature decreases.
Heat flows naturally from a warm area to a cooler area and the heat pump takes
advantage of this principle. The heat pump essentially consists of a compressor, an
inside coil and fan and an outside coil and fan. A refrigerant flows inside the coils,
under pressure applied by the compressor.
The refrigerant boils at a very low temperature (as low as -15° F) and becomes a
vapor, just as water becomes a vapor (steam) when boiled. This vapor is sucked into
the compressor where it becomes a high pressure, high temperature vapor.
When heating, the refrigerant is then forced through a coil within part of the heat
pump located indoors. A fan blows cool air over the coil, the vapor cools, turns back
to a liquid, releasing heat that is blown through a duct system to heat the house.
The cycle begins again as the cooled liquid refrigerant is pumped back outside after
releasing it’s heat. On the way, it passes through an expansion valve, lowering the
refrigerant's pressure and temperature again so it can boil more easily in the outdoor
coil.
In its cooling mode, the heat pump system works in reverse, extracting available heat
from indoors and transferring it outside.
Heat pumps are most economical when they can be used year-round for both winter
heating and summer cooling.
The efficiency of a heat pump varies significantly with the outdoor temperature.
While a heat pump may be twice as efficient as a conventional heating system at
50°F. When the outdoor temperature drops to less than 30°F, the heat pump must be
supplemented with an auxiliary heating system such as electric resistance. At
temperatures of 15°F or less the heat pump may shut off and the backup heating
system takes over. This is the heat pump balance point.
In a dual-fuel system, the heat pump is supplemented with a standard furnace, which
takes over when it becomes more efficient than the heat pump at very low
temperatures. The heat pump type setting (HP) of the Heat/Cool Type (HC) setup
parameter will allow aux heat to stage with the heat pump. A dual-fuel type setting
(dF) will not allow both systems to run at the same time.

Glossary
Anticipators
Used to anticipate the drop or rise in temperature and energize the
appropriate system before reaching the set point. Anticipators affect how
tightly the setpoint temperature is maintained.
Auto Dead Band
Sets the minimum separation in auto mode between heat and cool setpoints
(with dual setpoints) or maximum drift before system latches alternate
mode (with single setpoint).
Balance Point
At low outdoor temperatures, the refrigeration cycle of a heat pump will not
be able to supply the heating requirements without the aid of a
supplementary heat source. At higher outdoor temperatures, it is inefficient
to use supplementary heat.
The heat pump balance point sets the minimum outdoor temperature
required to allow operation of the heat pump. Additionally, for conventional
heat pump system types (Heat/Cool Type setup parameter = HP), the AuxHeat Balance Point sets the maximum outdoor temperature to allow
operation of the auxiliary heat.
Since dual fuel system types only allow operation of one system at a time,
only one balance point is available.
Blower (Fan)
An air-handling device for moving air in a distribution system.
Call
A call is the action taken by the thermostat when it sends a signal to turn on
the heating or cooling system.
Dual Fuel
A heat pump used in conjunction with an existing fossil fueled furnace.
Emergency Heat (Supplementary Electric Heat)
The auxiliary (AUX) or emergency heat provided at temperatures below a
heat pump's balance point. It is usually electrical resistance heat.
Extended Cool
Extends the cool setpoint range to the full auto range of 38 to 99°F.
Forced Air
A type of heating system that uses a blower motor to move air through the
furnace and into the ductwork.
Furnace
Equipment used to convert heating energy, such as fuel, oil, gas or
electricity, to usable heat. It usually contains a heat exchanger, a blower and
the controls to operate the system.
Heat Pump
A unit that both cools and heats. A heat pump system can be either a split
system or a packaged system. A heat pump can be used in conjunction with
a gas/oil/LP furnace (using the furnace instead of electric resistance heat
when temperatures fall below about 35º F).

Humidity
The total amount of moisture in air. Relative humidity (RH) is the amount
of moisture in air, relative to its total capability based upon its temperature
(dew point). Moisture will condense on surfaces that are below this dew
point.
HVAC
Heating, ventilation and air conditioning.
Interstage Differential
The proportional temperature error (0.5 to 3.0º) to trigger the second stage
(2-stage only), such as the aux heat for a heat pump type system.
Run Fan in Heat Calls
A device setting that activates the fan output during heat (W ) calls . (F or
heat pump or dual fuel system types, this setting activates the fan during
calls for auxiliary heat.
Setpoint
The user selectable temperature you want the system to maintain.
Time Delay (Timer Guards)
Refers to a safety device or circuit that will not allow restart for three
minutes.
