Crestron CHV-TSTATEX infiNET EX Thermostat infiNET EX Thermostat: CHV-TSTATEX Introduction 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.
Crestron CHV-TSTATEX infiNET EX Thermostat 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 is never missed, resulting in faultless operation - something that is of the utmost importance when it comes to HVAC control and home automation.

Crestron CHV-TSTATEX infiNET EX Thermostat Uploading and Upgrading 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 (or device).
Crestron CHV-TSTATEX infiNET EX Thermostat Crestron Studio / SIMPL Windows If a Crestron Studio (or SIMPL Windows) program is provided, it can be uploaded to the control system using Crestron Studio (or SIMPL Windows) or Crestron Toolbox. Firmware Check the Crestron Web site to find the latest firmware. (New users must register to obtain access to certain areas of the site, including the FTP site.) Upgrade CHV-TSTATEX firmware via Crestron Toolbox. 1.
Crestron CHV-TSTATEX infiNET EX Thermostat Problem Solving Troubleshooting The following table provides corrective action for possible trouble situations. If further assistance is required, please contact a Crestron customer service representative. CHV-TSTATEX Troubleshooting TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION No power from system. Check for +24 V on 24C connector. Check circuit breaker powering furnace or boiler. Check thermostat wiring. Check batteries (if running on battery power).
Crestron CHV-TSTATEX infiNET EX Thermostat CHV-TSTATEX Troubleshooting (Continued) TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION System cycles too quickly. Anticipator setting is too low. Reprogram anticipator setting (refer to “Setup Mode Parameters/Functions” which starts on page 24). Poor battery life. Ensure that the power switch selection position is proper for the expected conditions.
Crestron CHV-TSTATEX infiNET EX Thermostat CHV-TSTATEX Troubleshooting (Continued) TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION Heat or cool call occurs but device does not indicate a heat or cool call. Steal power function may be causing problems with HVAC system. Change Power DIP Switch to 24VAC and ensure two AA batteries are installed. Improper wiring connections. Recheck wiring connections. Auto mode is disabled in setup.
Crestron CHV-TSTATEX infiNET EX Thermostat Appendix: 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.
Crestron CHV-TSTATEX infiNET EX Thermostat Glossary Anticipators Used to anticipate the drop or rise in temperature and energize the appropriate system before reaching the set point. Anticipators affect how tightly the setpoint temperature is maintained. Auto Dead Band Sets the minimum separation in auto mode between heat and cool setpoints (with dual setpoints) or maximum drift before system latches alternate mode (with single setpoint).
Crestron CHV-TSTATEX infiNET EX Thermostat 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 (dew point). Moisture condenses on surfaces that are below this dew point. 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), such as the aux heat for a heat pump type system.
