Thermostats: CHV-TSTAT and CHV-THSTAT
Introduction
Functions and Features
The CHV-TSTAT and CHV-THSTAT series are wall-mounted universal thermostats
that can be part of a Crestron Home
capable of controlling one or two-stage heating and cooling systems. Each
thermostat is available in three colors: almond, black and white. The suffix ‘A’, ‘B’,
and ‘W’, respectively denotes color, e.g., CHV-TSTATB is a black unit. For
simplicity within this guide, color suffix is omitted and the designations CHVTSTAT and CHV-THSTAT are used except where noted.
Functional Summary
• User adjustable temperature and/or humidity control of one and two-stage
heating and cooling systems
• 128 x 64 transflective 2.75 inch (6.99 cm) LCD display
• Fahrenheit or Celsius indication
• Four-front panel buttons for setup, configuring and temperature/humidity
adjustments
• Back light (with each button press) for night viewing
• Supports up to two remote temperature and/or temperature/humidity sensors.
Future firmware releases will support up to four remote sensors per thermostat
• Operates as a stand-alone device or in a Cresnet
• Extended functionality as a Cresnet device for lighting control, alarms, etc.
The CHV-TSTAT provides temperature control, while the CHV-THSTAT provides
temperature and humidity control. Temperature and humidity information is
provided through a transflective LCD display. Four front panel buttons and the LCD
display provide temperature and/or humidity indication and control, current system
status, and current fan mode. The LCD also provides status indicators denoting when
heat, cool, humidity or fan outputs are energized; a message indicator, so users know
when a message is waiting to be read; a net indicator to denote when the network is
active and a hold indicator that identifies when the thermostat is overriding the
Cresnet temperature set point commands.

Thermostats Crestron CHV-TSTAT and CHV-THSTAT
Remote Sensors
The current firmware release supports the addition of two optional remote sensors:
temperature only (CHV-RTS) and/or temperature/humidity (CHV-RTHS), for both
thermostats.
Outdoor conditions can be imported from the optional external sensors CHV-RTS or
CHV-RTHS, temperature and temperature/humidity respectively.
Subsequent firmware releases will support the addition of up to four optional remote
sensors, in any combination, for each thermostat. For additional information about
the sensors, refer to the latest revision of the CHV-RTS & CHV-RTHS Installation
Guide (Doc. 8189), which is available from the Crestron website
(www.crestron.com).
NOTE: The CHV-TSTAT and CHV-THSTAT allow the user to set a temperature
that the heating and/or cooling system maintains. This is called the “Set Point”. Refer
to “Operating the Thermostat” on page 21 for more information.
NOTE: Crestron sensors are suitable for mounting in dry or damp locations as
defined by the National Electrical Code.
NOTE: Installers should have a strong working knowledge of HVAC systems.
Heating and Cooling Systems
The CHV-TSTAT can control the following heating and cooling systems:
• One stage heat
• One stage heat, one stage cool
• One stage heat, one stage cool: heat pump with auxiliary heat
• Two stage heat
• Two stage heat, one stage cool
• One stage heat, two stage cool
• Two stage heat, two stage cool
• Two stage heat, two stage cool: heat pump with auxiliary heat
NOTE: Two Stage Heating – Unlike traditional furnaces that turn on and run at full
capacity with each demand for heating, two-stage heat operates like two separate
furnaces to maintain more consistent comfort in your home. The unit starts out
running in its first stage, and operates at a fraction of its heating capacity. This
reduced capacity is sufficient to warm your home on mild winter days. But when the
temperature outside goes very low, the furnace adjusts to full capacity (second stage)
to meet the demand for heat within the home.
Two Stage Cooling – In warm weather, the first stage of the cooling equipment
operates at a fraction of the total cooling capacity. On very hot days, the second stage
of the cooling equipment energizes, and the cooling system operates at full capacity.

Setup
Network Wiring
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Downloads | Product Manuals | Wiring Diagrams section of the Crestron website
(www.crestron.com)
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the power factor of
each unit to be daisy-chained must be added together to determine the power factor
of the entire chain. If the unit is a home-run from a Crestron system power supply
network port, the power factor of that unit is the power factor of the entire run. The
length of the run in feet and the power factor of the run should be used in the
following resistance equation to calculate the value on the right side of the equation.
Resistance Equation
R <
40,000
L x PF
.
R = Resistance (refer to table below).
Where:
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the table below.
Wire Gauge Values
RESISTANCE WIRE GAUGE
4 16
6 18
10 20
15 22
13 Doubled CAT 5
8.7 Tripled CAT 5
NOTE: All Cresnet wiring must consist of two twisted-pairs. One twisted pair is the
+24V conductor and the GND conductor and the other twisted pair is the Y
conductor and the Z conductor.
NOTE: For larger networks (i.e., greater than 28 network devices), it may be
necessary to add a Cresnet Hub/Repeater to maintain signal quality throughout the
network. Also, for networks with lengthy cable runs or varying types of network
devices, it may be desirable to add a hub/repeater after only 20 network devices.
Identity Code
Every equipment and user interface within the network requires a unique Cresnet
identity code (NET ID). These codes are assigned a two-digit hexadecimal number
from 03 to FE. The NET ID of the unit must match the NET ID specified in the
SIMPL Windows or D3 Pro program. Refer to “Device Options” on page 18 for a
description of assigning the NET ID to the thermostat and “Setting the Net ID in
Device Settings” on page 26 for an example of the SIMPL Windows procedure.

Inquiries" on page 38.
The CHV-TSTAT and CHV-THSTAT thermostats do not require programming
when used as stand alone devices. Programming as part of a Cresnet system allows
additional functionality, including:
Global Update and Global Page display – Allows viewing and setting the
temperature/humidity for an entire house in a multi-thermostat system.
Remote Function pages – Allows system control of other functions (lighting,
alarms, etc.). Two pages, two functions per page.
System Messaging – Allows the control system to send text messages to the
thermostat.
Setup is easy thanks to Crestron’s Windows
-based programming software. The
Crestron D3 Pro Software creates a complete project, with no special programming
required. D3 Pro completes all necessary programming for a base system including
the control system program. Once D3 Pro creates the project, the system interfaces
and program logic can be customized. It can also be modified with Crestron
development tools (i.e., SIMPL Windows
) software, although this should rarely be
necessary.
The program output of D3 Pro is a SIMPL Windows program with much of the
functionality encapsulated in macros. Therefore, extending the capabilities of the
system is very easy. Crestron D3 Pro and SIMPL Windows are intended for users
with different levels of programming knowledge. The flexibility of each is
proportional to the degree of programming expertise (i.e., the more flexible, the
more a programmer needs to know and account for). Of course, one can begin
programming using the easiest method (Crestron D3 Pro) and use advanced
techniques that are available from SIMPL Windows to customize the job.
D3 Pro comes with templates for all supported interfaces. If a user wishes to create a
touchpanel project using templates with a different look-and-feel this can be
accomplished by making a custom template. This custom template can then be used
by D3 Pro to create the final project files. The following are recommended software
version requirements for the PC:
• [Optional] D3 Pro version 1.1 or later (scheduled for May 2003). Requires
SIMPL Windows.
• SIMPL Windows version 2.03.18 or later. Using D3 Pro will require
SIMPL Windows 2.04 or later.
• Requires SIMPL+ Cross Compiler version 1.1.
• Crestron Database version 15.9.3 or later if using D3 Pro. If only using
SIMPL Windows, Crestron Database 15.8.8 is required.

Programming with Crestron D3 Pro
The easiest method of
rogramming, but does not
offer as much flexibility as
SIMPL Windows.
Crestron D3 Pro offers automatic programming for residential and commercial
systems. The interface of this tool guides you through a few basic steps for
designating rooms and specifying the control system, devices, and functionality.
Crestron D3 Pro then programs the system, including all control system logic.
Crestron D3 Pro is fully integrated with the Crestron suite of software development
tools and accesses these tools behind the scenes, enabling you to easily create robust
systems.
Programming with SIMPL Windows
NOTE: The following assumes that the reader has knowledge of SIMPL Windows.
If not, refer to the extensive help information provided with the software.
NOTE: In the following description, the PRO2 control system is used.
SIMPL Windows is Crestron's software for programming Crestron control systems.
It provides a well-designed graphical environment with a number of workspaces
(i.e., windows) in which a programmer can select, configure, program, test, and
monitor a Crestron control system. SIMPL Windows offers drag and drop
functionality in a familiar Windows® environment.
PRO2 System View
This section describes a sample SIMPL Windows program that includes a CHVTSTAT.
Configuration Manager is where programmers “build” a Crestron control system by
selecting hardware from the Device Library. In Configuration Manager, drag the
PRO2 from the Control Systems folder of the Device Library and drop it in the upper
pane of the System Views. The PRO2 with its associated communication ports is
displayed in the System Views upper pane.
The System Views lower pane displays the PRO2 system tree. This tree can be
expanded to display and configure the communications ports.

To incorporate a CHV-THSTAT or CHV-TSTAT into the system, drag one of the
symbols for the thermostat from the Crestron Sensing Modules folder of the Device
Library and drop it on C2-NET Device slot in System Views. The PRO2 system tree
displays the thermostat symbol in Slot 9, with a default NET ID of 2A as shown in
the example graphic below.
C2Net Device, Slot 9
Setting the Net ID in Device Settings
Double-click the thermostat icon in the upper pane to open the “Device Settings”

Basic and Advanced Symbols in Programming Manager
Programming Manager is where programmers “program” a Creston control system
by assigning signals to symbols.
You may choose between two different symbol sets for the thermostats, advanced
and basic. The advanced symbol allows a broader range of functions, including the
ability to control other devices (lighting, alarms, etc.), interact with other
thermostats, receive messages from the Crestron system, import and export
temperature and humidity information. The basic symbol, while simpler, still
provides all the necessary connections to operate and control a Heating Ventilation
and Air Conditioning (HVAC) system.

Appendix A: Glossary
Anticipators – Used to anticipate the drop or rise in temperature and energize the
appropriate system before reaching the set point.
Balance Point – The lowest outdoor temperature at which the refrigeration cycle of
a heat pump will supply the heating requirements without the aid of a
supplementary heat source.
Blower (Fan) – An air-handling device for moving air in a distribution system.
BTU - British Thermal Unit – In scientific terms, it represents the amount of
energy required to raise one pound of water one degree Fahrenheit. One
BTU is the equivalent of the heat given off by a single wooden kitchen
match.
Call – A call is when the thermostat requests the heating or cooling system to turn
on.
Damper – Found in ductwork, this movable plate opens and closes to control
airflow. Dampers are used effectively in zoning to regulate airflow to
certain rooms.
Dead Band – The minimal differential between Heating and Cooling.
Dual Fuel – A heat pump used in conjunction with an existing furnace.
Emergency Heat (Supplementary Electric Heat) – The auxiliary or emergency heat
provided at temperatures below a heat pump's balance point. It is usually
electrical resistance heat.
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 Exchanger – A device for the transfer of heat energy from the source to the
conveying medium of air or water. Most common combinations are:
Refrigerant to air or Refrigerant to water (DX), Water to air (hydronic),
Steam to air, Steam to water.
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 (dewpoint). Moisture will condense on surfaces that are below
this dewpoint.
HVAC – Heating, ventilation and air conditioning.
Setpoint – The thermostat temperature set to begin heating or cooling.
Time Delay (Timer Guards) – Refers to a safety device or circuit that will not allow
restart for 5 minutes.
Two Stage Heating –The heating unit starts out running in its first stage, and
operates at about 68% of its capacity. When the temperature outside goes
very low, the system adjusts to full capacity (second stage) to meet the
demand.

Appendix B: 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 Pump Operation
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.
