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® total control system. The thermostats are
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
CHV-TSTAT and CHV-THSTAT are used except where noted.

Crestron CHV-TSTAT and CHV-THSTAT
Firmware Versions
The new features, and consequent changes to the SIMPL Windows symbol
programming, for firmware version 2.0 and later make it incompatible for use with
X-generation control processors. In addition, upgrading to release 2.0 and later from
a previous release will require a complete re-programming of the thermostat.
Remote Sensors
Firmware version 2.0 and later supports up to four optional remote sensors, two for
each input channel: temperature only (CHV-RTS), temperature/humidity
(CHV-RTHS), and slab sensor (CHV-RSS) for both thermostats. Information from
two sensors that share an input channel is averaged together in the
temperature/humidity calculations.
Outdoor conditions, -40º to 170º F (-40º to 77º C), can be imported from the
CHV-RSS slab sensor.
For additional information about the sensors, refer to the latest revision of the
CHV-RTS & CHV-RTHS Installation Guide (Doc. 8189), and the CHV-RSS
Installation Guide (Doc.6229) which are 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 55 for more information.
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)
•
Wide range cool option suitable for wine cellars or other chilling processes*
•
Slab settings for heating and floor warming systems*
*Firmware version 2.0 or higher.
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.

Network Wiring
CAUTION: In order to ensure optimum performance over the full range of your
installation topology, Crestron Certified Wire, and only Crestron Certified Wire,
should be used. Failure to do so may incur additional charges if support is required to
identify performance deficiencies as a result of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to
do so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient power can lead to
unpredictable results or damage to the equipment. Please use the Crestron Power
Calculator to help calculate how much power is needed for the system.
<http://www.crestron.com/dealer-tech_resources/power_calculator.asp>
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Crestron website (www.crestron.com).
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the Cresnet power usage of each network unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the Cresnet power
usage of each unit to be daisy-chained must be added together to determine the
Cresnet power usage of the entire chain. If the unit is a home-run from a Crestron
system power supply network port, the Cresnet power usage of that unit is the
Cresnet power usage of the entire run. The length of the run in feet and the Cresnet
power usage 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
LxP
Where: R = Resistance (refer to the following table).
L = Length of run (or chain) in feet.
P = Cresnet power usage 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.

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
equipment, 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 identity
code (Net ID). These codes are two-digit hexadecimal numbers from 03 to FE. The
Net ID of each unit must match an ID code specified in the SIMPL Windows
program. Refer to “Setting the Net ID in Device Settings” on page 61 for details of
8 • Thermostats: CHV-TSTAT and CHV-THSTAT
Operations and Installation Guide – DOC. 8163C
Crestron CHV-TSTAT and CHV-THSTAT
Thermostats
the SIMPL Windows procedure. The Net ID of the Thermostats has been factory set
to 2A. The Net IDs of multiple thermostats in the same system must be unique. Net
IDs are changed from a personal computer (PC) via the Crestron Viewport.
NOTE: The Crestron Viewport is available as a pull-down command from SIMPL
Windows and VisionTools® Pro-e (Tools | Viewport) or as a standalone utility. The
Viewport utility performs multiple system tasks, primarily via an RS-232 or TCP/IP
connection between the control system and a PC. It is used to observe system
processes, upload new operating systems and firmware, change system and network
parameters, and communicate with network device consoles and touchpanels, among
many other tasks. Viewport can function as a terminal emulator for generic file
transfer. All of these functions are accessed through the commands and options in
Viewport menus. Therefore, for its effectiveness as a support and diagnostic tool, the
Crestron Viewport may be preferred over development tools when uploading
programs and projects.
NOTE: For detailed information on establishing communication between the PC and
control system, refer to “Communication Settings” in the Operations Guide of the
control system. If communication cannot be established, refer to the
“Troubleshooting Communications” section in the respective Operations Guide for
the control system.
NOTE: The NET ID can also be changed using the setup screens.
NOTE: Firmware version 2.40 and later supports Touch Settable ID.
There are two different methods—Method A or Method B—for setting the Net ID:
Method A (Cresnet address-settable ID), described as follows, applies to devices in
a Cresnet system with a 2-Series control system and requires that a single unit be the
only network device connected to the control system.
Method B (Touch Settable ID or TSID), which begins on page 10, applies to all
TSID-ready devices in a Cresnet system with 2-Series control system upgrade file
(CUZ) version 3.029 or later. TSID functionality makes it possible for the control
system to recognize a network device via its serial number, which is stored in the
device’s memory. This method does not require that any devices be disconnected
from the network; Net IDs may be set with the entire Cresnet system intact. This
method requires the use of the Crestron Viewport version 3.35 or later.
Use the appropriate method to set the Net ID.
Method A (Cresnet address-settable ID)
1.
Ensure that the device requiring a Net ID change is the only unit connected
to the control system.
2.
Open the Crestron Viewport.
3.
From the Viewport menu, select Functions | Set Network ID. The software
checks the baud rate and then opens the "Set Network ID" window.
4.
In the "Set Network ID" window, select the device requiring a Net ID
change from the Current Network Devices text window.
5.
Select the new Net ID for the device from the Choose the new network ID
for the selected device (Hex): text box.

6.
Click Set ID to initiate the change. This will display the "ID command has
been sent" window.
7.
In the "Command Complete" window, click OK.
8.
In the Current Network Devices text window, verify the new Net ID code.
9.
In the "Set Network ID" window, click Close.
NOTE: The new Net ID code may also be verified by selecting Diagnostic | Report
Network Devices in the Viewport (alternately, select F4).
10. Repeat this procedure for each additional network device requiring a Net ID
change.
Method B (Touch Settable ID)
Before using this method, you should have a list of all current network devices and
their Net IDs, to avoid assigning duplicate IDs.
Set Net ID by TSID
These procedures are for TSID-enabled network devices during the initial
configuration of a Cresnet system or when such devices are being added/replaced.
1.
Ensure that all network devices are connected to the control system.
2.
Open the Crestron Viewport version 3.35 or later.
3.
From the Viewport menu, select Functions | Assign Cresnet ID by Serial
Number. The “Set Net ID by TSID” window appears. The window is first
displayed with the data fields empty.
4.
Click on the Search for Touch Settable Devices button. The system
searches the network and lists all TSID-enabled devices found. The list is
similar to the report produced by pressing F4 (Report Network Devices);
the first eight digits of each line constitute the TSID number (hexadecimal
form of the serial number).

5.
Enter either the serial number or TSID number of the device that requires a
change. The list scrolls to and highlights the device listing. The listing
should show the device’s default Cresnet ID (a.k.a. Net ID).
6.
Enter the Cresnet ID that the device should be set to and click OK. The
number you enter should appear on the list.
CAUTION: This function does not prevent you from setting duplicate IDs. Be sure
to check current assignments before entering the desired Cresnet ID number.
Serial Number to TSID Conversion
This utility is useful in a case where there are multiple devices of the same type on a
network, you need to locate a particular one, you know the TSID but not the serial
number, and your site installation list is based on device serial numbers. In this (or
the reverse) situation, do the following:
1.

Crestron CHV-TSTAT and CHV-THSTAT
Wiring Diagrams
The wiring diagrams that follow show connections for the CHV-TSTAT and
CHV-THSTAT. The heating or cooling system can supply power to the thermostat,
or a separate transformer can supply it. In many installations, spare conductors are
available to supply 24 VAC to the thermostat, using the C (24 VAC common)
connection on the HVAC equipment.
The P4 jumper internally connects either the RH (Reference Heat system) or RC
(Reference Cooling system), relieving the installer from connecting a jumper from
the 24(R) terminal to the RH or RC terminal.
If power is available from the HVAC system, follow the diagrams for the proper P4
jumper connection.
When power is not available from the HVAC system, a separate transformer,
connected between 24(R) and 24(C) terminals, can provide power to the thermostat.
When powered by a separate transformer, ensure that the P4 jumper is connected
across pins 2 and 3 (No Connection) to prevent damage to the thermostat and the
HVAC system.
CAUTION: The P4 Jumper Position on the Circuit Board is critical to proper
operation. Improper P4 jumper position can cause equipment damage. The P4
jumper connects the 24(R) terminal to the RH, or RC connector. Refer to the
following illustration.

NOTE: Ensure that the power circuits are shut off at the source before connecting
the thermostat. Provide disconnect means and overload protection as required for the
power supply.
NOTE: Ensure that the transformer has sufficient power for all the thermostats in
the system, or use multiple transformers. Refer to the power requirements in
“Specifications” on page 3.
The following diagrams are examples of connections for heat, heat/cool and onestage and two-stage heat pump systems, and various slab systems.
NOTE: Use either connector O or B as required, for changeover control.

Setup Notes
The following are general setup notes.
NOTE: Refer to “System Connections” on page 8 for remote sensor connections to
the thermostat.
NOTE: The Offset option permits recalibration of the room temperature sensor.
There are various reasons why users may want to adjust the temperature. The
selection number is the number of degrees added or subtracted to the actual
temperature. The range is -6° to +6°F. Factory default is 0°. This adjustment changes
the actual regulated temperature, not just the display.
NOTE: The sensors are used for temperature and humidity averaging. Choose USE
to include each sensor, or OMIT to exclude each sensor in the averaging equation.
Sensors that have the same designation (for example, outdoor) are averaged together.
NOTE: The thermostat will not leave the setup mode unless a valid sensor selection
is made.
NOTE: When the Reverse SMODE Dir (reverse system mode direction) selection
is set to Yes on the Screen Options page, the arrow keys (▲ ▼) can be used to select
system mode functions in both directions.

System Types and Definitions
The first setup choice is the heat system type. There are three main types of
heating/cooling systems.
1.
Heat/Cool, Radiant Heat or Forced Air Heating/Cooling, 1 or 2 Stages
2.
Heat Pump, 1 or 2 Stages, Auxiliary Heat or Dual Fuel
3.
Slab System (Slab1 through Slab 5B)
1.
Heat/Cool Systems Definitions
Radiant Heat systems: Radiant heat is a form of hydronic (hot water) heat
that circulates hot water through pipes (baseboard radiation systems) or
special tubing and installs on the perimeter of the house or underneath
floors.
Forced Air systems: In a ducted heating/cooling system, a large fan
(blower) forces heated air from the furnace into the ducts and enters the
rooms through a register or grill in the floor or wall.
One or Two Stages: Unlike traditional furnaces that turn on and run at full
capacity with each demand for heating, two-stage furnaces operate like two
separate furnaces. The unit begins to run in its first stage, and operates at a
fraction of its heating capacity. This reduced capacity is sufficient on mild
winter days. On very cold days, the furnace adjusts to full capacity (second
stage) to meet the demand for heat.
Heat/Cool system setup begins on page 28.
2.
Heat Pump Systems Definitions
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.
Dual Fuel: A dual fuel system combines an energy-efficient air-source heat
pump with a new or existing oil, gas or propane furnace. The furnace runs
in place of the heat pump in cold weather.
Aux (Auxiliary) Heat: When the a heat pump can no longer efficiently
transfer heat from the outside air, the thermostat automatically turns on a
secondary heat source, such as electric resistive heat.
Heat pump system setup begins on page 31.

Slab Systems
Slab heating works from the ground up. The heating components are installed
below the floor or are embedded in a concrete slab. Heat radiates from the floor
to warm the space above. The CHV-TSTAT and CHV-THSTAT support seven
variations of slab heat systems.
SLAB 1: Floor warming only. Operates the slab heat to maintain a particular
slab temperature. System mode is enabled/disabled with Floor
Warming Heat and OFF inputs. Slab is maintained at the slab setpoint
temperature value. Connection to the slab output relay is terminal W1.
Refer to setup on page 34.
SLAB 2: One stage space heat with slab maximum. Maintains a particular air
temperature using the slab to heat the space. Will not heat over the
slab maximum temperature even if this results in the space being
under-heated. Connection to the slab output relay is terminal W1.
Refer to setup on page 37.
SLAB 3: One stage space heat with slab maximum and slab minimum.
Performs the same operation as SLAB 2, and also keeps the slab at
least as warm as slab setpoint. This may result in the space being
overheated to maintain the slab minimum temperature. Connection to
the slab output relay is terminal W1. Refer to setup on page 40.
SLAB 4A: Two-stage space heat with slab maximum and one stage cool.
Maintains the air temperature using the slab for heat, up to the slab
maximum. Augments the air heating by using a second stage of heat
(generally a forced air system). Allows the second stage to operate by
itself should the slab reach is maximum temperature and shut off.
Cools the space with cooling call. Intended for heat-cool type forced
air systems, with relay output connections to terminal W1 for slab,
terminal W2 for 2nd stage heat, and terminal Y1 for cooling. Refer to
setup on page 43.
SLAB 4B: Same operation as SLAB4A, but intended for a heat pump type
second stage. Relay output connections are terminal W1 for slab heat,
with heat pump-type connections on terminals Y1/O/G for cooling
and heating calls. Aux heat is on terminal W2. Refer to setup on page
46.
SLAB 5A: One stage space heat and cool with floor warming. Combines the
operation of a space heating/cooling thermostat with a floor-warming
thermostat. Maintains the slab at slab setpoint, and maintains the
space at the heat, cool, or auto setpoints. Systems effectively operate
independently. Heat/Cool/Auto/Off sets the space control modes, and
Floor Warming HEAT/OFF sets the slab mode. Intended for heatcool style systems, with slab connection on terminal W1, space heat
on terminal W2, and space cool on terminal Y1. Refer to setup on
page 49.
SLAB 5B: Same as SLAB5A, but for heat pump space systems, with slab heat
on terminal W1, and space heat/cool on terminals Y1/O/G. Aux heat
is on terminal W2. Refer to setup on page 52.

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 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. Requires SIMPL Windows.
•
SIMPL Windows version 2.05.22 or later with library update 297.
•
Requires SIMPL+ Cross Compiler version 1.1.
•
Crestron Database version 16.3.0 or later if using D3 Pro.

Programming with Crestron D3 Pro
The easiest method of
programming, 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. Both the older and newer versions of the thermostat models are supported.
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.
NOTE: The slotted thermostat symbol described in this section is for 2-Series only.
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.
This section describes a sample SIMPL Windows program that includes a
CHV-THSTAT.
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.
PRO2 System View
The System Views lower pane displays the PRO2 system tree. This tree can be
expanded to display and configure the communications ports.

heat setpoint value to 710 (for 71°). Similarly, if the analog
value of the cool setpoint equals 200 (for 20°) and the halfdegree Celsius option is selected, a rising edge of
<CoolSetpoint-> will lower the cool setpoint value to 195 (for
19.5° C). Continuing to assert the up or down inputs at the

Input that allows the outdoor temperature value to be retrieved
from Cresnet for display on the "outdoor" page, This value is
ignored when a thermostat has a remote-outdoor sensor
connected to it. The temperature value is in tenths of a degree
with no Fahrenheit or Celsius conversion. That is, the value is
assumed to be in the native unit of the thermostat that is
transmitting the temperature reading. Thus a value of 30 would
display a temperature of 3° regardless of the temperature
scale. If a heat pump thermostat does not have its own outdoor
sensor, it may use this value for balance point action.* This is
useful for multi-thermostat heat pump systems without discrete
sensors.
*The heat pump balance point is the outdoor temperature
below which heat pump operation is locked out, and auxiliary
heat runs in place of it. The auxiliary balance point is the
outdoor temperature above which auxiliary heat is locked out.

CoolSetpoint
Auto(1pt)Setpoint
DEFINITION
Sets the temperature regulating setpoint for heat-only, coolonly and single point auto mode in tenths of a degree. The
scale (Fahrenheit or Celsius) is based on the current setting in
the unit. The displayed setpoint value is rounded to whole
degrees Fahrenheit or Celsius, or half degrees Celsius if that
option is enabled. This means that if the value 721 is presented
on the heat setpoint input, the thermostat LCD will display a
setpoint of 72°. Similarly, if the value 204 is presented on the
cool setpoint input and the half degree Celsius option is
enabled, the thermostat LCD will display a setpoint of 20.5°.
Valid analog values are as follows:
Heat setpoint: 380 to 890 (38° to 89°F); or 30 to 320 (3° to
32°C).
Cool setpoint: 590 to 990 (59° to 99°F); or 150 to 370 (15° to
37°C).
Cool setpoint (if wide-range cool mode is enabled): 380 to 990
(38° to 99°F); or 30 to 370 (3° to 37°C).
Auto (1pt) setpoint: 380 to 990 (38° to 99°F); or 30 to 370 (3° to
37°C).
The setpoints will saturate in both directions. Thus sending 0
will set the setpoint to its minimum value, while sending 1000
will set the setpoint to its maximum value.

Slab(min)Setpoint-
DEFINITION
Raises (+) or lowers (-) the slab regulating setpoint on
the rising edge of the input.
The setpoint is adjusted in whole degrees Fahrenheit or
Celsius, or half degrees Celsius if that option is selected.
Thus if the analog value of the slab setpoint equals 700
(for 70°), a rising edge of <Slab(min)Setpoint+> will
raise the slab setpoint value to 710 (for 71°). Similarly, if
the analog value of the slab setpoint equals 200 (for 20°)
and the half-degree Celsius option is selected, a rising
edge of <Slab(min)Setpoint-> will lower the setpoint
value to 195 (for 19.5°C).
Continuing to assert the up or down inputs at the limits
of each setpoint will not affect the setpoint. That is, the
setpoint will hold at its maximum or minimum setting.
High/1 (rising edge) = Slab setpoint up or down;
Low/0 = no effect

Digital
FloorWarmSysModeOff_F
SlabSetpoint
Reports the status of the floor-warming system.
High/1 = Floor-warming system On/Off
Input
Analog
Sets the slab regulating setpoint in tenths of a degree.
The scale (Fahrenheit or Celsius) is based on the
current setting in the unit.
The displayed setpoint value is rounded to whole
degrees Fahrenheit or Celsius, or half-degrees Celsius if
that option is enabled. This means that if the value 721
is presented on the slab setpoint input, the thermostat
LCD will display a slab setpoint of 72°. Similarly, if the
value 204 is presented on the slab setpoint input and the
half-degree Celsius option is enabled, the thermostat
LCD will display a slab setpoint of 20.5°.
Valid analog values range from 380 to 1210 (38° to
121°F); or 3 to 495 (3° to 49.5°C).
The setpoints will saturate in both directions. Thus
sending 0 will set the setpoint to its minimum value,
while sending 1300 will set the setpoint to its maximum
value.
SlabSetpoint_F

Analog
Reports the slab regulating setpoint in tenths of a

Viewport Error Log Message Formats
When a remote sensor that has been designated as USE, SLAB, or OD in the Setup
Sensors screen generates an error, a message is sent to the error log. Retrieve this
message using Viewport, Function | 2-Series | Error Log | Show Error Log.
Error Message Format
Sensor <channel> type <designator> <CHA errors>, <CHB
errors> Errors @ <cycle count>
Where:
channel is the sensor channel string
designator is the sensor setup designation
CHA errors/CHB errors are the number of errors on each sub-channel
cycle count is the number of read cycles that have occurred.
NOTE: Both sub-channels have their error count reported, regardless of the sensors
connected.
This message is sent upon the first error on the channel, as well as every 100 errors
thereafter. The following is an example output, as seen in Viewport, when a single
OD sensor on channel one fails.
Error: Message from device Slot-09.ID-2A: Sensor R1T

Local Error Messages
When a critical sensor fails and prevents the safe or intended operation of the HVAC
equipment, an error message flashes on the main screen.
This error message appears as a text message under the line that normally reads ON
LINE and VIEW MSG. The thermostat messages are shown as follows in
descending priority.
ERROR
DESCRIPTION
ERR! NO AT SRC
Indicates that no air temperature source is present,
because all available sensors designated USE have
generated errors during the current read cycle. HVAC
operation is suspended and relays are cleared, except on
SLAB1 type. SLAB1 type cannot generate this error
because it does not have an air temperature USE type.
ERR! NO SB SRC
Indicates that no slab temperature source is present,
because all available sensors designated SLAB have
generated errors during the current read cycle. HVAC
operation is suspended on all slab modes (1, 2, 3, 4A,
4B, 5A, 5B).
ERR! NO HM SRC
Indicates that no humidity sources are present, because
all available sensors designated USE have generated
errors during the current read cycle. Humidifier operation
is suspended and HUM relay is cleared.
ERR! NO OD SRC
Indicates that no outdoor source is present and the setup
says at least one remote is supposed to be providing OD
data (designated OD). This error does not disable HVAC
operation because it is not absolutely essential. All
heatpump modes that use outdoor temperature for
balance point operation will eventually stage or switch to
auxiliary heat and thus prevent the space from freezing.
NOTE: All of these conditions are self-healing if the sensor begins sending valid
data.

Appendix A: Glossary
Anticipators – Used to anticipate the drop or rise in temperature and energize the
appropriate system before reaching the set point.
Auto Dead Band Degree (Auto DdBand Deg) – Sets the minimum separation in
auto mode between the heat and cool setpoints, or the changeover band in
1-point auto mode.
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.
Dual Setpoint Auto – Enables the two-point auto mode.
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.
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.
Interstage Differential – The proportional temperature error (0.5 to 3.0º) to trigger
the second stage (2-stage only).

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.
