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 three-speed fan applications. The CHV-TSTATEX-FCU supports on/off control of the valves and the fan in four-pipe fan coil applications, eliminating the need for an additional device dedicated to controlling the fan coil unit itself.
infiNET EX Communications
Ultra-reliable infiNET EX wireless technology provides steadfast two-way RF communications throughout a residential or commercial structure without the need for physical control wiring. Employing a 2.4 GHz mesh network topology, each infiNET EX device functions as an expander, passing command signals through to every other infiNET EX device within range (approximately 150 feet or 46 meters indoors), ensuring that every command reaches its intended destination without disruption[3].
The CHV-TSTATEX communicates with a Crestron control system via an infiNET EX Wireless Gateway (model CEN-RFGW-EX, DIN-AP3MEX, or MC3[4]). Up to 100 infiNET EX devices may coexist on a single wireless network, and every non-battery-powered device that is added to the network effectively increases the range and stability of the entire network by providing multiple redundant signal paths[3]. Built-in Dynamic Frequency Allocation continuously monitors RF conditions, automatically selecting the clearest channel to prevent interference from neighboring networks, cordless phones, and microwaves.
Automation System Integration
The wireless connection to the control system allows the functions of the CHV-TSTATEX to be controlled from touch screens, keypads, wireless remotes, computers, or even a mobile device. It supports unlimited flexibility for remote control, scheduling, and integration with other devices and systems. 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
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.
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.
