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 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. For simplicity within this guide, color suffix is omitted and the designations CHVTSTAT and CHV-THSTAT are used except where noted.

Functional Summary

• User adjustable temperature and/or humidity control of one and two-stage heating and cooling systems

• Supports seven slab system configurations

• 128 x 64 transflective 2.75 inch (6.99 cm) LCD display

• Fahrenheit or Celsius indication

• Four-front panel buttons for setup, configuring and temperature/humidity

adjustments

• Back light (with each button press) for night viewing

• Supports up to four remote temperature and/or temperature/humidity sensors.

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 2.0 and later supports up to four optional remote sensors, two for each input channel: temperature only (CHV-RTS), temperature/humidity (CHVRTHS), and slab sensor (CHV-RSS) for both thermostats. Information from two sensors that share an input channel is averaged together in the temperature/humidity calculations.

Outdoor conditions, -40º to 170º F (-40º to 77º C), can be imported from the CHVRSS slab sensor.

For additional information about the sensors, refer to the latest revision of the CHVRTS & CHV-RTHS Installation Guide (Doc. 8189), and the CHV-RSS Installation Guide (Doc.6229) which are available from the Crestron website (www.crestron.com).

NOTE: The CHV-TSTAT and CHV-THSTAT allow the user to set a temperature that the heating and/or cooling system maintains. This is called the “Set Point”. Refer to “Operating the Thermostat” on page 55 for more information.

Heating and Cooling Systems

The CHV-TSTAT can control the following heating and cooling systems:

• One stage heat

• One stage heat, one stage cool

• One stage heat, one stage cool (heat pump with auxiliary heat)

• Two stage heat

• Two stage heat, one stage cool

• One stage heat, two stage cool

• Two stage heat, two stage cool

• Two stage heat, two stage cool (heat pump with auxiliary heat)

• Wide range cool option suitable for wine cellars or other chilling processes*

• Slab settings for heating and floor warming systems*

*Firmware version 2.0 or higher.

NOTE: Two Stage Heating – Unlike traditional furnaces that turn on and run at full capacity with each demand for heating, two-stage heat operates like two separate furnaces to maintain more consistent comfort in your home. The unit starts out running in its first stage, and operates at a fraction of its heating capacity. This reduced capacity is sufficient to warm your home on mild winter days. But when the temperature outside goes very low, the furnace adjusts to full capacity (second stage) to meet the demand for heat within the home.

Two Stage Cooling – In warm weather, the first stage of the cooling equipment operates at a fraction of the total cooling capacity. On very hot days, the second stage of the cooling equipment energizes, and the cooling system operates at full capacity.

Setup

Network Wiring

NOTE: When installing network wiring, refer to the latest revision of the wiring diagram(s) appropriate for your specific system configuration, available from the Downloads | Product Manuals | Wiring Diagrams section of the Crestron website (www.crestron.com)

When calculating the wire gauge for a particular Cresnet run, the length of the run and the power factor of each network unit to be connected must be taken into consideration. If Cresnet units are to be daisy-chained on the run, the power factor of each unit to be daisy-chained must be added together to determine the power factor of the entire chain. If the unit is a home-run from a Crestron system power supply network port, the power factor of that unit is the power factor of the entire run. The length of the run in feet and the power factor of the run should be used in the following resistance equation to calculate the value on the right side of the equation.

Resistance Equation

R <

40,000

L x PF

R = Resistance (refer to table below).

Where:

L = Length of run (or chain) in feet . PF = Power factor of entire run (or chain).

The required wire gauge should be chosen such that the resistance value is less than the value calculated in the resistance equation. Refer to the table below.

Wire Gauge Values

RESISTANCE WIRE GAUGE

13 Doubled CAT5

8.7 Tripled CAT5

NOTE: All Cresnet wiring must consist of two twisted-pairs. One twisted pair is the +24V conductor and the GND conductor and the other twisted pair is the Y conductor and the Z conductor.

NOTE: For larger networks (i.e., greater than 28 network devices), it may be necessary to add a Cresnet Hub/Repeater to maintain signal quality throughout the network. Also, for networks with lengthy cable runs or varying types of network equipment, it may be desirable to add a hub/repeater after only 20 network devices.

Identity Code

Every equipment and user interface within the network requires a unique identity code (Net ID). These codes are two-digit hexadecimal numbers from 03 to FE. The Net ID of each unit must match an ID code specified in the SIMPL Windows program. Refer to “Setting the Net ID in Device Settings” on page 61 for details of

8 • Thermostats: CHV-TSTAT and CHV-THSTAT Operations and Installation Guide – DOC. 8163C

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. The Viewport utility performs multiple system tasks, primarily via an RS-232 or TCP/IP connection between the control system and a PC. It is used to observe system processes, upload new operating systems and firmware, change system and network parameters, and communicate with network device consoles and touchpanels, among many other tasks. Viewport can function as a terminal emulator for generic file transfer. All of these functions are accessed through the commands and options in Viewport menus. Therefore, for its effectiveness as a support and diagnostic tool, the Crestron Viewport may be preferred over development tools when uploading programs and projects.

NOTE: For detailed information on establishing communication between the PC and control system, refer to “Communication Settings” in the Operations Guide of the control system. If communication cannot be established, refer to the “Troubleshooting Communications” section in the respective Operations Guide for the control system.

NOTE: The NET ID can also be changed using the setup screens.

NOTE: Firmware version 2.40 and later supports Touch Settable ID.

There are two different methods—Method A or Method B—for setting the Net ID:

Method A (Cresnet address-settable ID), described as follows, applies to devices in a Cresnet system with a 2-Series control system and requires that a single unit be the only network device connected to the control system.

Method B (Touch Settable ID or TSID), which begins on page 10, applies to all TSID-ready devices in a Cresnet system with 2-Series control system upgrade file (CUZ) version 3.029 or later. TSID functionality makes it possible for the control system to recognize a network device via its serial number, which is stored in the device’s memory. This method does not require that any devices be disconnected from the network; Net IDs may be set with the entire Cresnet system intact. This method requires the use of the Crestron Viewport version 3.35 or later.

Use the appropriate method to set the Net ID.

Method A (Cresnet address-settable ID)

1. Ensure that the device requiring a Net ID change is the only unit connected to the control system.

2. Open the Crestron Viewport.

3. From the Viewport menu, select Functions | Set Network ID. The software checks the baud rate and then opens the "Set Network ID" window.

4. In the "Set Network ID" window, select the device requiring a Net ID change from the Current Network Devices text window.

5. Select the new Net ID for the device from the Choose the new network ID for the selected device (Hex): text box.

Operations and Installation Guide – DOC. 8163C Thermostats: CHV-TSTAT and CHV-THSTAT • 9

Thermostats Crestron CHV-TSTAT and CHV-THSTAT

6. Click Set ID to initiate the change. This will display the "ID command has been sent" window.

7. In the "Command Complete" window, click OK.

8. 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. Repeat this procedure for each additional network device requiring a Net ID change.

Method B (Touch Settable ID)

Before using this method, you should have a list of all current network devices and their Net IDs, to avoid assigning duplicate IDs.

Set Net ID by TSID

These procedures are for TSID-enabled network devices during the initial configuration of a Cresnet system or when such devices are being added/replaced.

1. Ensure that all network devices are connected to the control system.

2. Open the Crestron Viewport version 3.35 or later.

3. From the Viewport menu, select Functions | Assign Cresnet ID by Serial Number. The “Set Net ID by TSID” window appears. The window is first displayed with the data fields empty.

4. Click on the Search for Touch Settable Devices button. The system searches the network and lists all TSID-enabled devices found. The list is similar to the report produced by pressing F4 (Report Network Devices); the first eight digits of each line constitute the TSID number (hexadecimal form of the serial number).

“Set Net ID by TSID” Window

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

10 • Thermostats: CHV-TSTAT and CHV-THSTAT Operations and Installation Guide – DOC. 8163C

Crestron CHV-TSTAT and CHV-THSTAT Thermostats

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. Be sure to check current assignments before entering the desired Cresnet ID number.

Serial Number to TSID Conversion

This utility is useful in a case where there are multiple devices of the same type on a network, you need to locate a particular one, you know the TSID but not the serial number, and your site installation list is based on device serial numbers. In this (or the reverse) situation, do the following:

1. Open the Crestron Viewport.

2. From the Viewport menu, select Functions | Serial Number ÅÆ TSID Conversion Tool. The “Serial Number ÅÆ TSID Conversion Tool” window is displayed.

“Serial Number to TSID Conversion Tool” Window

3. Enter the serial number or TSID number as instructed; press the appropriate button to obtain the corresponding number.

NOTE: Enter serial numbers, including spaces, exactly as they appear on the unit label. Alpha characters in serial numbers or TSID numbers may be entered in upper or lower case.

Thermostats Crestron CHV-TSTAT and CHV-THSTAT

Wiring Diagrams

The wiring diagrams that follow show connections for the CHV-TSTAT and CHVTHSTAT. 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.

The P4 jumper internally connects either the RH (Reference Heat system) or RC (Reference Cooling system), relieving the installer from connecting a jumper from the 24(R) terminal to the RH or RC terminal.

If power is available from the HVAC system, follow the diagrams for the proper P4 jumper connection.

When power is not available from the HVAC system, a separate transformer, connected between 24(R) and 24(C) terminals, can provide power to the thermostat. When powered by a separate transformer, ensure that the P4 jumper is connected across pins 2 and 3 (No Connection) to prevent damage to the thermostat and the HVAC system.

CAUTION: The P4 Jumper Position on the Circuit Board is critical to proper operation. Improper P4 jumper position can cause equipment damage. The P4 jumper connects the 24(R) terminal to the RH, or RC connector. Refer to the following illustration.

Connects 24(R) to RH

No Connection

3 4

NOTE: Ensure that the power circuits are shut off at the source before connecting the thermostat. Provide disconnect means and overload protection as required for the power supply.

NOTE: Ensure that the transformer has sufficient power for all the thermostats in the system, or use multiple transformers. Refer to the power requirements in “Specifications” on page 3.

The following diagrams are examples of connections for heat, heat/cool and onestage and two-stage heat pump systems, and various slab systems.

NOTE: Use either connector O or B as required, for changeover control.

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 single-gang box.

Thermostats and sensors are mounted 60 inches (152.4 cm) above the finished floor (HVAC industry standard).

Refer to the following illustrations. Do the following to install the CHV-TSTAT or the CHV-THSTAT.

NOTE: When installing directly on drywall, use anchoring screws and hardware. Make sure the back of the thermostat is flush with drywall and the unit is level.

Required Hardware

• Thermostat

• Phillips screwdriver (not supplied)

• Two 6/32 x 1 inch panhead screws (supplied) for mounting to a

single-gang box

• Single-gang box (not supplied)

• Wall anchors (not supplied) and screws (not supplied) for

mounting directly to drywall

1. Separate thermostat front plate from back plate (you may need to exert force when removing the faceplate).

2. Turn off the circuit breaker when connecting power to the thermostat, and connect wiring as required (wiring goes through center hole on back plate).

NOTE: Ensure the correct position of the P4 jumper; refer to pages 12 through 21.

3. Attach back plate to drywall with screws and anchors (anchor hardware not provided) 60 inches above the finished floor. Thermostat may also be mounted to a single-gang box mounted horizontally, using the two 6/32 x 1 inch panhead screws provided. If using a five-sided single-gang box, fill with insulation material to minimize wall air ingress. Ensure that the thermostat is level and the ventilation holes in the backplate are not blocked.

4. Note orientation of front plate connection leads and reattach the front plate on the back plate (make sure front plate snaps in place and no wires are pinched).

NOTE: If replacing an existing thermostat, make note of the wire colors and positions before removing the old thermostat.

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. Press and hold the MODE and VIEW buttons simultaneously for five seconds to access the setup menus.

2. Press VIEW to select the parameter. A box appears around the selected parameter.

3. Press the Arrow keys (▲▼) to choose the value of the selected parameter.

4. Use the MODE button to advance to the next setup screen.

Setup Notes

The following are general setup notes.

NOTE: Refer to “System Connections” on page 8 for remote sensor connections to the thermostat.

NOTE: The Offset option permits recalibration of the room temperature sensor. There are various reasons why users may want to adjust the temperature. The selection number is the number of degrees added or subtracted to the actual temperature. The range is -6° to +6°F. Factory default is 0°. This adjustment changes the actual regulated temperature, not just the display.

NOTE: The sensors are used for temperature and humidity averaging. Choose USE to include each sensor, or OMIT to exclude each sensor in the averaging equation. Sensors that have the same designation (for example, outdoor) are averaged together.

NOTE: The thermostat will not leave the setup mode unless a valid sensor selection is made.

NOTE: When the Reverse SMODE Dir (reverse system mode direction) selection is set to Yes on the Screen Options page, the arrow keys (▲ ▼) can be used to select

Operations and Installation Guide – DOC. 8163C Thermostats: CHV-TSTAT and CHV-THSTAT • 25

system mode functions in both directions.

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. Heat Pump, 1 or 2 Stages, Auxiliary Heat or Dual Fuel

3. Slab System (Slab1 through Slab 5B)

1. Heat/Cool Systems Definitions

Radiant Heat systems: Radiant heat is a form of hydronic (hot water) heat

that circulates hot water through pipes (baseboard radiation systems) or special tubing and installs on the perimeter of the house or underneath floors. Forced Air systems: In a ducted heating/cooling system, a large fan (blower) forces heated air from the furnace into the ducts and enters the rooms through a register or grill in the floor or wall. One or Two Stages: Unlike traditional furnaces that turn on and run at full capacity with each demand for heating, two-stage furnaces operate like two separate furnaces. The unit begins to run in its first stage, and operates at a fraction of its heating capacity. This reduced capacity is sufficient on mild winter days. On very cold days, the furnace adjusts to full capacity (second stage) to meet the demand for heat.

Heat/Cool system setup begins on page 28.

2. Heat Pump Systems Definitions

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. Dual Fuel: A dual fuel system combines an energy-efficient air-source heat pump with a new or existing oil, gas or propane furnace. The furnace runs in place of the heat pump in cold weather. Aux (Auxiliary) Heat: When the a heat pump can no longer efficiently transfer heat from the outside air, the thermostat automatically turns on a secondary heat source, such as electric resistive heat.

Heat pump system setup begins on page 31.

3. 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. Slab is maintained at the slab setpoint temperature value. Connection to the slab output relay is terminal W1. Refer to setup on page 34.

SLAB 2: One stage space heat with slab maximum. Maintains a particular air

temperature using the slab to heat the space. Will not heat over the slab maximum temperature even if this results in the space being under-heated. Connection to the slab output relay is terminal W1. Refer to setup on page 37.

SLAB 3: One stage space heat with slab maximum and slab minimum.

Performs the same operation as SLAB 2, and also keeps the slab at least as warm as slab setpoint. This may result in the space being overheated to maintain the slab minimum temperature. Connection to the slab output relay is terminal W1. Refer to setup on page 40.

SLAB 4A: Two-stage space heat with slab maximum and one stage cool.

Maintains the air temperature using the slab for heat, up to the slab maximum. Augments the air heating by using a second stage of heat (generally a forced air system). Allows the second stage to operate by itself should the slab reach is maximum temperature and shut off. Cools the space with cooling call. Intended for heat-cool type forced air systems, with relay output connections to terminal W1 for slab, terminal W2 for 2

stage heat, and terminal Y1 for cooling. Refer to

setup on page 43.

SLAB 4B: Same operation as SLAB4A, but intended for a heat pump type

second stage. Relay output connections are terminal W1 for slab heat, with heat pump-type connections on terminals Y1/O/G for cooling and heating calls. Aux heat is on terminal W2. Refer to setup on page

46.

SLAB 5A: One stage space heat and cool with floor warming. Combines the

operation of a space heating/cooling thermostat with a floor-warming thermostat. Maintains the slab at slab setpoint, and maintains the space at the heat, cool, or auto setpoints. Systems effectively operate independently. Heat/Cool/Auto/Off sets the space control modes, and Floor Warming HEAT/OFF sets the slab mode. Intended for heatcool style systems, with slab connection on terminal W1, space heat on terminal W2, and space cool on terminal Y1. Refer to setup on page 49.

SLAB 5B: Same as SLAB5A, but for heat pump space systems, with slab heat

on terminal W1, and space heat/cool on terminals Y1/O/G. Aux heat is on terminal W2. Refer to setup on page 52.

The CHV-TSTAT and CHV-THSTAT thermostats do not require programming when used as stand alone devices. Programming as part of a Cresnet system allows additional functionality, including:

Global Update and Global Page display – Allows setting the temperature/humidity for an entire house in a multi-thermostat system.

Remote Function pages – Allows system control of other functions (lighting, alarms, etc.). Two pages, two functions per page.

System Messaging – Allows the control system to send text messages to the thermostat.

Setup is easy thanks to Crestron’s Windows Crestron D3 Pro software creates a complete project, with no special programming required. D3 Pro completes all necessary programming for a base system including the control system program. Once D3 Pro creates the project, the system interfaces and program logic can be customized. It can also be modified with Crestron development tools (i.e., SIMPL Windows) software, although this should rarely be necessary.

-based programming software. The

The program output of D3 Pro is a SIMPL Windows program with much of the functionality encapsulated in macros. Therefore, extending the capabilities of the system is very easy. Crestron D3 Pro and SIMPL Windows are intended for users with different levels of programming knowledge. The flexibility of each is proportional to the degree of programming expertise (i.e., the more flexible, the more a programmer needs to know and account for). Of course, one can begin programming using the easiest method (Crestron D3 Pro) and use advanced techniques that are available from SIMPL Windows to customize the job.

D3 Pro comes with templates for all supported interfaces. If a user wishes to create a touchpanel project using templates with a different look-and-feel this can be accomplished by making a custom template. This custom template can then be used by D3 Pro to create the final project files. The following are recommended software version requirements for the PC:

• [Optional] D3 Pro version 1.1 or later. Requires SIMPL Windows.

• SIMPL Windows version 2.05.22 or later with library update 297.

• Requires SIMPL+ Cross Compiler version 1.1.

• Crestron Database version 16.3.0 or later if using D3 Pro.

rogramming, 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 D3 Pro is fully integrated with the Crestron suite of software development tools and accesses these tools behind the scenes, enabling you to easily create robust systems. Both the older and newer versions of the thermostat models are supported.

Programming with SIMPL Windows

NOTE: The following assumes that the reader has knowledge of SIMPL Windows. If not, refer to the extensive help information provided with the software.

NOTE: In the following description, the PRO2 control system is used.

NOTE: The slotted thermostat symbol described in this section is for 2-Series only.

SIMPL Windows is Crestron's software for programming Crestron control systems. It provides a well-designed graphical environment with a number of workspaces (i.e., windows) in which a programmer can select, configure, program, test, and monitor a Crestron control system. SIMPL Windows offers drag and drop functionality in a familiar Windows® environment.

PRO2 System View

This section describes a sample SIMPL Windows program that includes a CHVTHSTAT.

Configuration Manager is where programmers “build” a Crestron control system by selecting hardware from the Device Library. In Configuration Manager, drag the PRO2 from the Control Systems folder of the Device Library and drop it in the upper pane of the System Views. The PRO2 with its associated communication ports is displayed in the System Views upper pane.

The System Views lower pane displays the PRO2 system tree. This tree can be expanded to display and configure the communications ports.

Thermostat Symbol in Programming Manager

Programming Manager is where programmers “program” a Creston control system by assigning signals to symbols.

This is a slotted symbol in which the functions are grouped together in six slots.

Slot 1 – Heat Cool Control

Slot 2 – Humidity Control

Slot 3 – Slab Control

Slot 4 – Current System State

Slot 5 – Display Functions

Slot 6 – System Configuration

NOTE: Because of changes to the symbol and other improved features, this version of the SIMPL Windows symbol is not compatible with previous firmware versions.

Program View of Slotted Symbol

NOTE: All temperatures, including setpoint values, are expressed in tenths of degrees. For example: sending 703 means 70.3.

The following are detail views of the six thermostat slots in the SIMPL windows symbol. Definitions of the symbol inputs and outputs follow each diagram.

Raises (+) or lowers (-) the temperature regulating setpoint for heat-only, cool-only and single point auto mode, on the rising edge of the input. The setpoint is adjusted in whole degrees Fahrenheit or Celsius, or half degrees Celsius if that option is selected. Thus if the analog value of the heat setpoint equals 700 (for 70°), a rising edge of <HeatSetpoint+> will raise the heat setpoint value to 710 (for 71°). Similarly, if the analog value of the cool setpoint equals 200 (for 20°) and the halfdegree Celsius option is selected, a rising edge of <CoolSetpoint-> will lower the cool setpoint value to 195 (for

19.5° C). Continuing to assert the up or down inputs at the limits of each setpoint will not affect the setpoint. That is, the setpoint will hold at its maximum or minimum setting.

High/1 (rising edge) = Setpoint up or down; Low/0 = no effect

Heat-only Cool-only Auto (auto selects heat or cool) Off (no HVAC operation) Auxiliary heat-only mode for heat pump systems (no effect on a heat/cool system). The staging for a particular mode does not affect these inputs.

High/1 (rising edge) = Select system mode; Low/0 = no effect

High/1 = System mode running; Low/0 = System mode not running

In On mode, the fan runs continually. In Auto mode, the fan runs only when the system calls for heat or cool.

High/1 (rising edge) = Select fan mode; Low/0 = no effect

High/1 = Fan mode selected; Low/0 = Fan mode not selected

Input that allows the outdoor temperature value to be retrieved from Cresnet for display on the "outdoor" page, This value is ignored when a thermostat has a remote-outdoor sensor connected to it. The temperature value is in tenths of a degree with no Fahrenheit or Celsius conversion. That is, the value is assumed to be in the native unit of the thermostat that is transmitting the temperature reading. Thus a value of 30 would display a temperature of 3° regardless of the temperature scale. If a heat pump thermostat does not have its own outdoor sensor, it may use this value for balance point action.* This is useful for multi-thermostat heat pump systems without discrete sensors.

*The heat pump balance point is the outdoor temperature below which heat pump operation is locked out, and auxiliary heat runs in place of it. The auxiliary balance point is the outdoor temperature above which auxiliary heat is locked out.

Sets the temperature regulating setpoint for heat-only, coolonly and single point auto mode in tenths of a degree. The scale (Fahrenheit or Celsius) is based on the current setting in the unit. The displayed setpoint value is rounded to whole degrees Fahrenheit or Celsius, or half degrees Celsius if that option is enabled. This means that if the value 721 is presented on the heat setpoint input, the thermostat LCD will display a setpoint of 72°. Similarly, if the value 204 is presented on the cool setpoint input and the half degree Celsius option is enabled, the thermostat LCD will display a setpoint of 20.5°.

Valid analog values are as follows:

Heat setpoint: 380 to 890 (38° to 89°F); or 30 to 320 (3° to 32°C).

Cool setpoint: 590 to 990 (59° to 99°F); or 150 to 370 (15° to 37°C).

Cool setpoint (if wide-range cool mode is enabled): 380 to 990 (38° to 99°F); or 30 to 370 (3° to 37°C).

Auto (1pt) setpoint: 380 to 990 (38° to 99°F); or 30 to 370 (3° to 37°C).

The setpoints will saturate in both directions. Thus sending 0 will set the setpoint to its minimum value, while sending 1000 will set the setpoint to its maximum value.

Reports the temperature regulating setpoint for heat-only, coolonly and single point auto mode, in tenths of a degree.

Output Digital 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.

Readings from local and remote sensors that have the same designator are averaged together. Thus two temperature sensors set to Use are averaged for the air temperature control, while two humidity sensors set to Use are averaged to determine the humidity.

A sensor designated as “Omit” signifies that the reading will not be included in such averaging.

Output Digital

Reports the designator assigned to the remote sensors. The CHV-TSTAT and CHV-THSTAT provide two remote channels. Each channel supports two sensors, for a maximum of four remote sensors. Crestron manufacturers three sensor models:

CHV-RTS: temperature sensor CHV-RTHS: dual temperature/humidity sensor CHV-RSS: slab sensor

Each sensor must be designated as Use, Omit, OD (Outdoor) or Slab.

Readings from local and remote sensors that have the same designator are averaged together. Thus two sensors set to Use are averaged for the air temperature control, while two OD readings are averaged to determine the outdoor temperature, and two Slab readings are averaged for the floor temperature.

A sensor designated as "Omit" signifies that the reading will not be included in such averaging.

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).

Reports the heat pump balance point and auxiliary balance point in tenths of a degree. The scale (Fahrenheit or Celsius) is based on the current setting in the unit.

HP values range from 0 to 890 (0 to 89 ˚F); 0r –180 to +310 (-18˚C to 31˚C).

The heat pump balance point is the outdoor temperature below which heat pump operation is locked out, and auxiliary heat runs in place of it.

The auxiliary balance point is the outdoor temperature above which auxiliary heat is locked out. Aux values range from 0 to 900 (0˚to 90˚F); or –170 to +320 (-17˚C to 32˚C).

Values range from 1 (lightest) to 10 (darkest).

Reports the temperature offset in tenths of a degree. The offset is the number of degrees added or subtracted from the actual sensed temperature. The scale (Fahrenheit or Celsius) is based on the current setting in the unit.

Values are as follows:

Fahrenheit: -60 to +60 (-6˚ to +6˚F) Celsius: -30 to +30 (-3.0˚to +3.0˚C)

This temperature offset changes the actual regulated temperature, not just the displayed temperature. The offset is set to “0” as shipped from the factory.

Reports the auto mode deadband value in tenths of a degree. The scale (Fahrenheit or Celsius) is based on the current setting in the unit.

Values are as follows:

Fahrenheit: 20 to 60 (2˚ to 6˚F)

Celsius: 10 to 30 (1˚ to 3˚C)

Half degrees Celsius mode: 10 to 35 (1˚ to 3.5˚C)

The deadband sets the minimum separation in auto mode between the heat and cool setpoints, or the changeover band in single point auto mode.

Reports the slab temperature regulation value. Values range from 1 to 6.

A lower number signifies more frequent cycles and faster response (tighter regulation), while a higher number signifies less frequent cycles and slower response (looser regulation).

Viewport Error Log Message Formats

When a remote sensor that has been designated as USE, SLAB, or OD in the Setup Sensors screen generates an error, a message is sent to the error log. Retrieve this message using Viewport, Function | 2-Series | Error Log | Show Error Log.

Error Message Format

Sensor <channel> type <designator> <CHA errors>, <CHB errors> Errors @ <cycle count>

Where:

channel is the sensor channel string designator is the sensor setup designation CHA errors/CHB errors are the number of errors on each sub-channel cycle count is the number of read cycles that have occurred.

NOTE: Both sub-channels have their error count reported, regardless of the sensors connected.

This message is sent upon the first error on the channel, as well as every 100 errors thereafter. The following is an example output, as seen in Viewport, when a single OD sensor on channel one fails.

Local Error Messages

When a critical sensor fails and prevents the safe or intended operation of the HVAC equipment, an error message flashes on the main screen.

This error message appears as a text message under the line that normally reads ON LINE and VIEW MSG. The thermostat messages are shown as follows in descending priority.

ERROR DESCRIPTION

ERR! NO AT SRC

ERR! NO SB SRC

ERR! NO HM SRC

ERR! NO OD SRC

Indicates that no air temperature source is present, because all available sensors designated USE have generated errors during the current read cycle. HVAC operation is suspended and relays are cleared, except on SLAB1 type. SLAB1 type cannot generate this error because it does not have an air temperature USE type.

Indicates that no slab temperature source is present, because all available sensors designated SLAB have generated errors during the current read cycle. HVAC operation is suspended on all slab modes (1, 2, 3, 4A, 4B, 5A, 5B).

Indicates that no humidity sources are present, because all available sensors designated USE have generated errors during the current read cycle. Humidifier operation is suspended and HUM relay is cleared.

Indicates that no outdoor source is present and the setup says at least one remote is supposed to be providing OD data (designated OD). This error does not disable HVAC operation because it is not absolutely essential. All heatpump modes that use outdoor temperature for balance point operation will eventually stage or switch to auxiliary heat and thus prevent the space from freezing.

NOTE: All of these conditions are self-healing if the sensor begins sending valid data.

auto mode between the heat and cool setpoints, or the changeover band in 1-point auto mode.

Balance Point – The lowest outdoor temperature at which the refrigeration cycle of

a heat pump will supply the heating requirements without the aid of a supplementary heat source.

Blower (Fan) – An air-handling device for moving air in a distribution system.

BTU - British Thermal Unit – In scientific terms, it represents the amount of

energy required to raise one pound of water one degree Fahrenheit. One BTU is the equivalent of the heat given off by a single wooden kitchen match.

Call – A call is when the thermostat requests the heating or cooling system to turn

on.

Damper – Found in ductwork, this movable plate opens and closes to control

airflow. Dampers are used effectively in zoning to regulate airflow to certain rooms.

Dead Band – The minimal differential between Heating and Cooling.

Dual Fuel – A heat pump used in conjunction with an existing furnace.

Dual Setpoint Auto – Enables the two-point auto mode.

Emergency Heat (Supplementary Electric Heat) – The auxiliary (AUX) or

emergency heat provided at temperatures below a heat pump's balance point. It is usually electrical resistance heat.

Forced Air – A type of heating system that uses a blower motor to move air through

the furnace and into the ductwork.

Furnace – Equipment used to convert heating energy, such as fuel, oil, gas or

electricity, to usable heat. It usually contains a heat exchanger, a blower and the controls to operate the system.

Heat Exchanger – A device for the transfer of heat energy from the source to the

conveying medium of air or water. Most common combinations are: Refrigerant to air or Refrigerant to water (DX), Water to air (hydronic), Steam to air, Steam to water.

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).

Appendix B: About Heat Pumps

In the heating mode, the efficiency of a heat pump decreases as the outdoor air temperature decreases.

Heat Pump Operation

Heat flows naturally from a warm area to a cooler area, and the heat pump takes advantage of this principle. The heat pump essentially consists of a compressor, an inside coil and fan, and an outside coil and fan. A refrigerant flows inside the coils, under pressure applied by the compressor.

The refrigerant boils at a very low temperature (as low as -15° F) and becomes a vapor, just as water becomes a vapor (steam) when boiled. This vapor is sucked into the compressor where it becomes a high pressure, high temperature vapor.

When heating, the refrigerant is then forced through a coil within part of the heat pump located indoors. A fan blows cool air over the coil, the vapor cools, turns back to a liquid, releasing heat that is blown through a duct system to heat the house.

The cycle begins again as the cooled liquid refrigerant is pumped back outside after releasing it’s heat. On the way, it passes through an expansion valve, lowering the refrigerant's pressure and temperature again so it can boil more easily in the outdoor coil.

In its cooling mode the heat pump system works in reverse, extracting available heat from indoors and transferring it outside.

Heat pumps are most economical when they can be used year-round for both winter heating and summer cooling.

The efficiency of a heat pump varies significantly with the outdoor temperature. While a heat pump may be twice as efficient as a conventional heating system at 50°F. When the outdoor temperature drops to less than 30°F, the heat pump must be supplemented with an auxiliary heating system such as electric resistance. At temperatures of 15°F or less the heat pump may shut off and the backup heating system takes over. This is the heat pump balance point. In a dual-fuel system, the heat pump is supplemented with a standard furnace, which takes over when it becomes more efficient than the heat pump at very low temperatures.
