Crestron CHV-TSTAT and CHV-THSTAT Thermostats Quick Installation Reference 1. Select a suitable location and run the connecting wires from the heating/cooling system and the Cresnet system. Refer to page 5 for a description of the thermostat connectors. Refer to page 7 for Network wiring details.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats Thermostats: CHV-TSTAT and CHV-THSTAT Introduction Functions and Features The CHV-TSTAT and CHV-THSTAT series are wall-mounted universal thermostats that can be part of a Crestron Home® total control system. The thermostats are capable of controlling one or two-stage heating and cooling systems. Each thermostat is available in three colors: almond, black and white. The suffix ‘A’, ‘B’, and ‘W’, respectively denotes color, e.g., CHV-TSTATB is a black unit.
Thermostats Crestron CHV-TSTAT and CHV-THSTAT Firmware Versions The new features, and consequent changes to the SIMPL Windows symbol programming, for firmware version 2.0 and later make it incompatible for use with X-generation control processors. In addition, upgrading to release 2.0 and later from a previous release will require a complete re-programming of the thermostat. Remote Sensors Firmware version 2.

Crestron CHV-TSTAT and CHV-THSTAT Thermostats Setup Network Wiring CAUTION: In order to ensure optimum performance over the full range of your installation topology, Crestron Certified Wire, and only Crestron Certified Wire, should be used. Failure to do so may incur additional charges if support is required to identify performance deficiencies as a result of using improper wire. CAUTION: Use only Crestron power supplies for Crestron equipment.

Crestron CHV-TSTAT and CHV-THSTAT Thermostats the SIMPL Windows procedure. The Net ID of the Thermostats has been factory set to 2A. The Net IDs of multiple thermostats in the same system must be unique. Net IDs are changed from a personal computer (PC) via the Crestron Viewport. NOTE: The Crestron Viewport is available as a pull-down command from SIMPL Windows and VisionTools® Pro-e (Tools | Viewport) or as a standalone utility.

In the Current Network Devices text window, verify the new Net ID code. 9. In the "Set Network ID" window, click Close. NOTE: The new Net ID code may also be verified by selecting Diagnostic | Report Network Devices in the Viewport (alternately, select F4). 10.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats 5. Enter either the serial number or TSID number of the device that requires a change. The list scrolls to and highlights the device listing. The listing should show the device’s default Cresnet ID (a.k.a. Net ID). 6. Enter the Cresnet ID that the device should be set to and click OK. The number you enter should appear on the list. CAUTION: This function does not prevent you from setting duplicate IDs.
Thermostats Crestron CHV-TSTAT and CHV-THSTAT 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 Thermostat Setup and Operation 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. Each system type is setup using nine screens. The available choices displayed on the setup screens depend on the type of system selected. Follow these directions to access the setup screens. 1.
Thermostats Crestron CHV-TSTAT and CHV-THSTAT NOTE: If an out-of-range setpoint is entered, the setpoint is assigned its limit value in that direction. NOTE: The Screen Options selected in setup are seen when the view key is pressed in normal operation. System Types and Definitions The first setup choice is the heat system type. There are three main types of heating/cooling systems. 1. Heat/Cool, Radiant Heat or Forced Air Heating/Cooling, 1 or 2 Stages 2.
Crestron CHV-TSTAT and CHV-THSTAT 3. Thermostats Slab Systems 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.

Thermostats Crestron CHV-TSTAT and CHV-THSTAT Programming with Crestron D3 Pro The easiest method of programming, but does not offer as much flexibility as SIMPL Windows. Crestron D3 Pro offers automatic programming for residential and commercial systems. The interface of this tool guides you through a few basic steps for designating rooms and specifying the control system, devices, and functionality. Crestron D3 Pro then programs the system, including all control system logic.

Crestron CHV-TSTAT and CHV-THSTAT Thermostats Slot 6 – System Configuration SIGNAL HeatCoolType I/O Output SIGNAL TYPE Digital HeatPumpType Slab1Type DEFINITION Indicates the heat/cool or slab system type that has been selected. Remains high for as long as the corresponding system is selected. The thermostats support single-stage and multi-stage heating and cooling systems, including conventional fossil fuel systems, heat pumps with auxiliary heat and slab heating systems.
Thermostats Crestron CHV-TSTAT and CHV-THSTAT Slot 6 – System Configuration (continued) SIGNAL ColdWeatherComp I/O Output SIGNAL TYPE Digital DEFINITION Indicates that cold weather compensation has been enabled. Remains high for as long as the mode is enabled. Outdoor low-temperature compensation modifies the humidifier output to prevent condensation on windows in cold weather.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats Slot 6 – System Configuration (continued) SIGNAL UseLocalTemp I/O SIGNAL TYPE Output Digital DEFINITION Reports the designator assigned to the local (internal) sensors. The CHV-TSTAT provides one internal temperature sensor; the CHV-THSTAT provides internal sensors for temperature and humidity. Each sensor must be designated as Use or Omit.
Thermostats Crestron CHV-TSTAT and CHV-THSTAT Slot 6 – System Configuration (continued) SIGNAL InterstageDifferential I/O SIGNAL TYPE Output Analog DEFINITION Reports the interstage differential in tenths of a degree. This is the proportional temperature error to trigger the second (Auxiliary) stage. The scale (Fahrenheit or Celsius) is based on the current setting in the unit. Values range from 0.5 to 8.0 (5°F to 30°F); or 0.25 to 4.5 (3° to 4.5°C).
Crestron CHV-TSTAT and CHV-THSTAT Thermostats Viewport ID String Using the Diagnostics | Report Network Devices (F4) command in Viewport, the thermostats output a string of characters that describe the setup and configuration of the thermostat. Refer to the following table for an explanation of this string. A semicolon separates each element of the setup string. Strings are contained within parenthesis, and follow one space after the PPN in the ID string. Refer to the following two examples of ID strings.

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 Main Screen Lower Object (Main Screen Lwr Obj) – Selects the data item displayed at the bottom of the main screen. Choice of: none, slab temperature, outdoor temperature, or indoor humidity. Run Fan in Heat Calls (Run Fan in Ht Calls) –A device setting that activates the fan output with W1/W2 heat calls. Does not enable operation on slab systems on the slab (W1) call. Setpoint – The thermostat temperature set to begin heating or cooling.
Thermostats Crestron CHV-TSTAT and CHV-THSTAT Appendix B: 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.
