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 CHVTSTAT and CHV-THSTAT are used except where noted.

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
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.

Thermostats

Crestron CHV-TSTAT and CHV-THSTAT
Remote Sensors
The current firmware release 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.
Subsequent firmware releases will support the addition of up to four optional remote
sensors, in any combination, for each thermostat. 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 21 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 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.

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

Where: R = Resistance (refer to table below).
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

Doubled CAT 5

8.7

Tripled CAT 5

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
devices, 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 Cresnet
identity code (NET ID). These codes are assigned a two-digit hexadecimal number
from 03 to FE. The NET ID of the unit must match the NET ID specified in the
SIMPL Windows or D3 Pro program. Refer to “Device Options” on page 18 for a
description of assigning the NET ID to the thermostat and “Setting the Net ID in
Device Settings” on page 26 for an example of the SIMPL Windows procedure.

CRESTRON

NOTE: Dual Setpoint Automatic – Selecting Yes allows the user to explicitly set
the heat and cool setpoints in auto mode. Selecting No shows one setpoint and the
thermostat automatically selects the operating systems to maintain that setpoint
temperature.
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°. Factory default is 0°. This adjustment changes
the actual regulated temperature, not just the display.

7. Sensors
Press the MODE button to access the SENSORS. Press VIEW to select each sensor
type. Press the Arrow keys (▲▼) to select the value of the parameter.
NOTE: The sensors are used for Temperature/Humidity Averaging. Choose USE to
include each sensor, or OMIT to exclude each sensor in the averaging equation.
Choose OMIT if the remote sensors are not installed.
NOTE: The thermostat will not leave the setup mode unless a valid sensor selection
is made. An omitted remote humidity sensor for a CHV-TSAT does not prevent
setup exit.
