The CHV-TSTATEX is a wireless thermostat featuring infiNET EX™ technology. The CHV-TSTATEX 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 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 is designed for one- or two-stage heating and one- or two-stage cooling control of baseboard, forced air, heat pump[1], and dual-fuel heat pump[1] 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.

Fan Coil Unit Support
The CHV-TSTATEX-FCU model of the infiNET EX™ thermostat provides the functionality of controlling fan coil units[2]. 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™ 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 touchpanels, 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 up a complete network of infiNET EX devices is simple, utilizing dynamic discovery (self-install) to locate and acquire each RF device automatically. 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 expander[3] for any other devices within range (approximately 150 feet 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.

Remote Sensors
Optional remote temperature sensors can be connected to the CHV-TSTATEX for enhanced flexibility and optimized performance. Climate can be regulated according to an average of multiple sensors, or the built-in sensors can be disabled entirely to allow the CHV-TSTATEX to be installed out of view. For heat pump-type systems, outdoor temperature can be monitored to optimize system performance. Compatible sensors include the CHV-RTS and the CHV-RSS.
