The CHV-TSTATRF is a wireless networked thermostat featuring infiNET™ wireless technology. The CHV-TSTATRF is designed to be installed easily in place of a conventional thermostat without requiring additional control wiring. Although it can be used as a standalone thermostat, the CHV-TSTATRF delivers enhanced functionality as part of a complete Crestron Home® automation system communicating via the infiNET wireless control network. The thermostat is available in three colors: the CHV-TSTATRFA in almond, the CHV-TSTATRFB in black and the CHV-TSTATRFW in white. For simplicity within this guide, these thermostats are referred to as CHV-TSTATRF. The features and specifications for all three thermostats are identical.
Features and Functions
Auto mode support requires firmware version 1.005.0005 or later.
Heat/Cool Thermostat
The CHV-TSTATRF 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™
Creston’s groundbreaking infiNET wireless technology affords reliable two-way communications throughout a home or office structure without the need for physical control wiring. Numerous infiNET thermostats and other devices can be linked to a control system via a single RF gateway. Employing a 2.4 GHz mesh network topology, every infiNET device functions as an RF repeater, increasing effective range and reinforcing the complete network by providing multiple redundant signal paths within the mesh network. In addition, a dedicated repeater (C2N-MNETRPT, sold separately) can be added to increase the system range.
NOTE: The CHV-TSTATRF must be powered by 24 Volt AC source and have its power setting on “24” to allow it to function as a repeater.
Automation System Integration
Its wireless connection to the control system allows the functions of the CHV-TSTATRF to be controlled from touchpanels, keypads, wireless remotes and computers to support 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-TSTATRF will remain operable to control the HVAC system.
Easy Installation
System design, installation and upgrade using infiNET thermostats along with lighting dimmers and other devices could not be easier. Since there is no control wiring required, the CHV-TSTATRF can be installed just like any conventional thermostat. Setting up a complete network of infiNET devices is simple, utilizing dynamic discovery (self-install) to locate and acquire each RF device automatically. Setting the RF ID of each device employs the same convention as Crestron’s familiar TSID method. The RF ID can also be set manually from the local display. Each device is programmable using Crestron SIMPL™ Windows®, SystemBuilder™ or D3 Pro™ 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 network.
Each device assigned to a common gateway automatically behaves as a repeater for any other device within range (approximately 150 feet indoors) and additional repeaters may be added if necessary. At all times, the infiNET gateway monitors each device on the network, ignoring any other 2.4 GHz signals and reconfiguring the entire network automatically in response to new sources of interference and other changes in RF conditions.

NOTE
CHV-TSTATRF in Heat Only Application
CHV-TSTATRF in Heat Only with Fan Application
NOTE: To run fan during heat calls, be sure to enable the HF parameter by setting it to “Y”. Refer to “Advanced Setup” which starts on page 19 for details.
CHV-TSTATRF in Cool Only Application
CHV-TSTATRF in Heat-Cool Application with Separate Systems
CHV-TSTATRF in Heat-Cool Application with Integrated Control Unit
CHV-TSTATRF in Heat Pump System Application with Integrated Controller
NOTE: Heat pump and dual-fuel heat pump systems require an outdoor temperature sensor (e.g. Crestron’s C2N-RTHS, sold separately) to function properly. In SIMPL Windows, connect the “Temp” output of the sensor to the “OutdoorTemp” input of the CHV-TSTATRF. For details, refer to the SIMPL Windows help file. If using D3 Pro or SystemBuilder refer to “Programming with Crestron D3 Pro or SystemBuilder”.
CHV-TSTATRF in Dual-Fuel Heat Pump Application
NOTE: The diagram above applies where furnace control is not integrated into the heat pump system.
Basic Thermostat Setup
NOTE: When first setting up the CHV-TSTATRF, batteries are required, even if you plan to power it from a constant 24 VAC supply.
Place the CHV-TSTATRF in the Setup mode by doing the following:
By default, the CHV-TSTATRF is configured to be powered by two AA alkaline batteries. In addition, in order to extend battery life, the device is able to steal power from the HVAC system by drawing a small amount of current through the heat or cool terminals. It 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.)
NOTE
If you have wired the thermostat so that 24 Volts AC will always be present on the “C” terminal (refer to “Wiring the CHV-TSTATRF to the HVAC System” which starts on page 10), you can set the unit to run from this power supply, thus eliminating the need for batteries (except during initial setup). The thermostat will run on battery power if 24 VAC is not present. In addition, when the unit detects 24 VAC is present, it will no longer “sleep”, meaning that it will offer real-time communication with the control system. When shipped from the factory, the CHV-TSTATRF will have a steal power setting. If you plan to power the device from a constant 24 VAC supply, you must still install batteries in order to access Setup mode and change the power setting to “24”.
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 “SP” to “24”. This is normal and the discrepancy will disappear within approximately 10 minutes.
The MNET ID of the CHV-TSTATRF has been factory set to 01. After an infiNET device is added to an infiNET network, its MNET ID must be changed to a value that can be addressed by the control system program (03 to 20). The MNET IDs of multiple CHV-TSTATRF devices on the same gateway must be unique. MNET IDs are changed locally using the setup parameter ability of the CHV-TSTATRF (refer to “Setup Mode Parameters/Functions” which starts on page 20). They can also be changed from a personal computer (PC) via the Crestron Toolbox™.
When setting the MNET ID, consider the following:
NOTE: An infiNET device can be acquired by only one gateway.
To acquire the CHV-TSTATRF, perform the following procedure:
NOTE
After the process is complete, take the C2N-MNETGW out of the Acquire mode by pressing ACQUIRE on the gateway. Refer to the latest revision of the C2N-MNETGW guide (Doc. 6317). To exit from Setup mode, press the FAN button on the CHV-TSTATRF.
The Fan icon will indicate the status of infiNET communication:
Setup Mode
After the CHV-TSTATRF is installed, it is necessary to set it up for a particular heating/cooling system. Please note that some of the setup parameters listed below will not always be available. Refer to “Setup Mode Parameters/Functions”, which starts for details. Place the CHV-TSTATRF in the Setup mode by doing the following:
Once in Setup mode, the display will indicate the currently selected setup parameter/function. Press and release the MODE button quickly (must be released within one second) to change to the next parameter/function in the list.
NOTE: Holding the MODE button for more than one second will reset the currently selected parameter/function to its default value.

| Auto Dead Band (will only appear when Auto mode is enabled) | db | 2 – 4 (for Fahrenheit) or 1 – 3 (for Celsius) | 2 | Used to set minimum separation between heat and cool setpoints (with dual setpoints) or maximum drift before system latches alternate mode (with single setpoint). |
| Temperature Offset | to | -9 to +9 (for Fahrenheit) or -5 to +5 (for Celsius) | 0 | Permits recalibration of room temperature sensor. This is the number of degrees added to or subtracted from the actual temperature. This adjustment changes the actual regulation temperature, not just the display. |
| Wide-range Cool Mode (Extended Cool) | EC | Enabled (Y) or Disabled (no) | no | Useful for wine chiller applications; extends the cool setpoint range down to the minimum used for Heat mode (38ºF/3ºC). |
| Heat Anticipator | HA | 1 – 6 | 3 | Lower setting results in more frequent cycles and faster response (tighter regulation). Higher setting results in less frequent cycles and slower response (looser regulation). The default value should suffice in nearly all installations. |
| Cool Anticipator | CA | 1 – 6 | 3 | Lower setting results in more frequent cycles and faster response (tighter regulation). Higher setting results in less frequent cycles and slower response (looser regulation). The default value should suffice in nearly all installations. |
| Heat pump Balance Point (will only appear for Heat pump and Dual- Fuel Heat pump systems) | Hb | 16 to 90 (for Fahrenheit) or -9 to 32 (for Celsius) or Disabled (–) | — | Heat pump systems have performance restrictions based on outdoor temperature. This setting is the minimum outdoor temperature at which the heat pump (or dual-fuel heat pump) system will run. |
| Aux-Heat Balance Point (will only appear for Heat pump type systems) | Ab | 16 to 90 (for Fahrenheit) or -9 to 32 (for Celsius) or Disabled (–) | — | Aux heat operation is locked out when outdoor temperature exceeds the Aux Heat Balance Point. Dual-fuel systems do not allow both the heat pump and the aux to run at the same time. |

System Mode
Off Mode
Heat Mode
Emergency Heat Mode
NOTE: Emergency 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 Emergency Heat mode.
Cool Mode
Auto Mode
NOTE: Auto mode support requires firmware version 1.005.0005 or later.
Dual Setpoint Auto Mode (“AU” = “d” in Setup Mode)
Single Setpoint Auto Mode (“AU” = “S” in Setup Mode)
NOTE: When using a single setpoint, the CHV-TSTATRF has a 20-minute change limiter to prevent system toggling.
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 HF setup parameter is set to “Y”). When set to ON the fan will always run.
Setpoints
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.
Hold
As an infiNET device, the CHV-TSTATRF can be controlled remotely via a Crestron control system. Most often, control of the thermostat will be achieved via a touchpanel or web-based graphical interface. 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 Sleep Time setting. Because of this, there will be a noticeable delay between the time a button is pressed on a touchpanel and when the thermostat reacts to the command. To account for this, the CHV-TSTATRF 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 touchpanel.
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 touchpanel. Instead, the thermostat will wake up approximately 10 seconds after the last button press to send its updated status to the control system.
NOTE: When the CHV-TSTATRF is powered via a constant 24 VAC supply, it will not go to sleep.

Earliest Version Software Requirements for the PC
NOTE: Crestron recommends that you use the latest software to take advantage of the most recently released features. The latest software is available from the Crestron website.
Crestron has developed an assortment of Windows-based software tools to develop an infiNET system. For the minimum recommended software versions, visit the Version Tracker page of the Crestron website (www.crestron.com/versiontracker).
Programming with Crestron D3 Pro or SystemBuilder
Crestron D3 Pro or SystemBuilder is the easiest method of programming but does not offer as much flexibility as SIMPL Windows. For additional details, download D3 Pro or SystemBuilder from the Crestron website and examine the extensive help files.
NOTE: Heat pump and dual-fuel heat pump systems require an outdoor temperature sensor (e.g. Crestron’s C2N-RTHS, sold separately) to function properly. Use a “Connect” step to attach the sensor’s “Temp” output to the “OutdoorTemp” input of the CHV-TSTATRF.
Programming with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the CHV-TSTATRF, it is recommended to use SystemBuilder or D3 Pro for configuring a system.
SIMPL Windows is Crestron’s premier software for programming Crestron control systems. It is organized into two separate but equally important “Managers”.
Configuration Manager
Configuration Manager is the view where programmers “build” a Crestron control system by selecting hardware from the Device Library.
NOTE: It is not recommended to add the CHV-TSTATRF directly. Instead, add one of the available “modules” listed underneath it as shown below.
Locating the C2N-MNETGW in the Device Library
C2Net Device, Slot 9
“CHV-TSTATRF Device Settings” Window
Program Manager
Program Manager is the view where programmers “program” a Crestron control system by assigning signals to symbols. The symbol can be viewed by double clicking on the icon or dragging it into Detail View. Each signal in the symbol is described in the SIMPL Windows help file (F1).
Example Program
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 established, 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) to ensure proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the CHV-TSTATRF; refer to the Crestron Toolbox help file for details. There is a single method of communication: indirect serial communication.
Indirect Serial Communication
Programs and Firmware
Program or firmware files may be distributed from programmers to installers or from Crestron to dealers. Firmware upgrades are available from the Crestron website as new features are developed after product releases. One has the option to upload programs via the programming software or to upload and upgrade via the Crestron Toolbox. For details on uploading and upgrading, refer to the SIMPL Windows help file or the Crestron Toolbox help file.
SIMPL Windows
Check the Crestron website to find the latest firmware. (New users may be required to register to obtain access to certain areas of the site, including the FTP site.) Upgrade CHV-TSTATRF firmware via Crestron Toolbox.
Since the CHV-TSTATRF might be “asleep”, there may be a delay of one minute or less before the update starts.
Program Checks
Using Crestron Toolbox, display the network device tree (Tools | Network Device Tree) to show all network devices connected to the control system and all infiNET devices that have been acquired by the CHV-TSTATRF (C2N-MNETGW). Right-click on the CHV-TSTATRF (C2N-MNETGW) to display actions that can be performed on the CHV-TSTATRF (C2N-MNETGW).
Troubleshooting
The following table provides corrective action for possible trouble situations. If further assistance is required, please contact a Crestron customer service representative.
CHV-TSTATRF Troubleshooting
| TROUBLE | POSSIBLE CAUSE(S) | CORRECTIVE ACTION |

Bootloader
The bootloader is a low-level version of the CHV-TSTATRF’s firmware that will become active in the event an upload of the standard firmware fails. This lets you perform some basic functions with the goal of getting the CHV-TSTATRF back to normal operation.
If the CHV-TSTATRF goes into bootloader, the large seven-segment display will show “Ld”, except when in Setup mode. All other LCD segments will be off. All button presses will be ignored, except for the sequence which enters Setup mode (refer to “Setup Mode” which starts).
From the bootloader, Setup mode will support only the following functions:
To restore functionality, try cycling power to the CHV-TSTATRF. If unit remains in bootloader, you should resend the latest firmware using Crestron Toolbox.
NOTE: To manually enter bootloader, press and hold the MODE button for 10 seconds during unit power up.
