Crestron CHV-TSTAT and CHV-THSTAT Thermostats Setup Network Wiring When wiring the Cresnet network, consider the following: • Use Crestron Certified Wire. • Use Crestron power supplies for Crestron equipment. • Provide sufficient power to the system. CAUTION: Insufficient power can lead to unpredictable results or damage to the equipment. Use the Crestron Power Calculator to help calculate how much power is needed for the system (www.crestron.com/calculators).
Crestron CHV-TSTAT and CHV-THSTAT Thermostats System Connections NOTE: Installers should have a strong working knowledge of HVAC systems.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats 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.

Crestron CHV-TSTAT and CHV-THSTAT Thermostats Installation The location of the thermostat can affect its performance and efficiency. Install the thermostat away from direct sunlight, drafts, doorways, skylights, and windows. Also make sure the thermostat is conveniently located for programming, and do not mount on an exterior wall. The thermostats may be mounted directly to drywall or to a 1-gang box. Thermostats and sensors are mounted 60 inches (~1.

Crestron CHV-TSTAT and CHV-THSTAT Thermostats Thermostat Setup Setup Procedure After the thermostat is installed, it is necessary to set it up for a particular heating/cooling system. There are nine types of heating and cooling systems. The available choices displayed on the setup screens depend on the type of system selected. Follow these directions to access the setup screens. 1. Press and hold the MODE and VIEW buttons simultaneously for 5 seconds to access the setup menus. 2.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats NOTE: When the Reverse SMODE Dir (reverse system mode direction) selection is set to Yes on the “SCRN OPTIONS” (screen options) setup screen, the arrow keys (▲ ▼) can be used to select system mode functions in both directions. NOTE: If an out of range setpoint is entered, it is ignored. NOTE: The screen options selected during setup are seen when the View key is pressed in normal operation.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats 3. Slab Systems Definitions 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.

Crestron CHV-TSTAT and CHV-THSTAT Thermostats 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-TSTAT and CHV-THSTAT Thermostats 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 Web site 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.

Crestron CHV-TSTAT and CHV-THSTAT Thermostats chained must be added together to determine the Cresnet power usage of the entire chain. If the unit is 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 wire gauge and the Cresnet power usage of the run should be used in the following equation to calculate the cable length value on the equation’s left side.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats Future Updates As Crestron improves functions, adds new features and extends the capabilities of the CHV-TSTAT/CHV-THSTAT, additional information may be made available as manual updates. These updates are solely electronic and serve as intermediary supplements prior to the release of a complete technical documentation revision. Check the Crestron Web site periodically for manual update availability and its relevance.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats Appendix A: 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-TSTAT and CHV-THSTAT Thermostats Glossary Anticipators Used to anticipate the drop or rise in temperature and energize the appropriate system before reaching the setpoint. 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.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats 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).
