Thermostats Crestron CHV-TSTAT and CHV-THSTAT
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.
Use the appropriate wiring diagram:
• Heating or Cooling System Powered (Refer to page 9).
• Separately Powered (Refer to page 10).
• Three Wire Heat Only with Fan (Refer to page 11).
• Five Wire Heat/Cool Systems (Refer to page 12)
• Single Stage and Two Stage Heat Pump (Refer to page 13).
2. Separate the thermostat from the backplate to expose the connections and mounting holes.
3. Mount the thermostat backplate (60 inches above the finished floor) directly to the wall with wall anchors (not
provided) and screws (not provided) or to a single-gang box (not provided) mounted horizontally, and connect
the wiring. Refer to page 15 for detailed mounting instructions and page 8 for detailed connector information. If
using a five-sided box, fill with insulation material to minimize wall air ingress.
4. Install the thermostat on the backplate (Refer to page 15).
5. Setup the thermostat (Refer to page 17).
6. Configure the thermostat (Refer to Operating the Thermostat on page 22).

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. For
simplicity within this guide, color suffix is omitted and the designations CHV-
TSTAT 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
• 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 two remote temperature and/or temperature/humidity sensors
• Operates as a stand-alone device or in a Cresnet®system
• Extended functionality as a Cresnet device for lighting control, alarms, etc.
NOTE: Because of the addition of new features and changes in the SIMPL Windows
symbol programming, firmware release 2.0 is not backward compatible with
firmware release 1.1 and earlier. Upgrading from 1.1 to 2.0 will require complete
reprogramming of the thermostat. In addition, version 2.0 is only compatible with
2-series control processors. Refer to Doc. 8163C for complete descriptions and
procedures concerning firmware version 2.0.
The CHV-TSTAT provides temperature control, while the CHV-THSTAT provides
temperature and humidity control. Temperature and humidity information is
provided through a transflective LCD display. Four front panel buttons and the LCD
display provide temperature and/or humidity indication and control, current system
status, and current fan mode. The LCD also provides status indicators denoting when
Operations and Installation Guide – DOC. 8163B Thermostats: CHV-TSTAT and CHV-THSTAT •1

Thermostats Crestron CHV-TSTAT and CHV-THSTAT
heat, cool, humidity or fan outputs are energized; a message indicator, so users know
when a message is waiting to be read; a net indicator to denote when the network is
active and a hold indicator that identifies when the thermostat is overriding the
Cresnet temperature set point commands.
Remote Sensors
Firmware release 1.1 and earlier supports the addition of two optional remote
sensors: temperature only (CHV-RTS) and/or temperature/humidity (CHV-RTHS),
for both thermostats.
Outdoor conditions can be imported from the optional external sensors CHV-RTS or
CHV-RTHS, temperature and temperature/humidity respectively.
For additional information about the sensors, refer to the latest revision of the CHV-
RTS & CHV-RTHS Installation Guide (Doc. 8189), which is 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 22 for more information.
NOTE: Crestron sensors are suitable for mounting in dry or damp locations as
defined by the National Electrical Code.
NOTE: Installers should have a strong working knowledge of HVAC systems.
Heating and Cooling Systems
The CHV-TSTAT, in conjunction with firmware release 1.0, 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
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.
