Introduction
The Crestron® HZ-THSTAT is a versatile, wall-mounted heating and cooling thermostat with
integrated humidistat capable of controlling two stage heat/cool systems, two stage heat pump
systems with two auxiliary heat stages, floor warming systems, and humidity systems. A Wi-Fi®
thermostat, the HZ-THSTAT delivers enhanced functionality when combined with a complete
Crestron automation system.
The 3.5 in. LCD touchscreen display is used to configure the system type, radiant floor, system
performance, sensor setup, and thermostat control settings.
Integrated proximity and ambient light sensors ensure the thermostat display looks perfect in
any room lighting condition. The RGB backlit status light bar indicates HVAC calls. The
thermostat behavior can be customized separately for day and night operating modes.
With Crestron Toolbox® software, the thermostat can be configured and debugged remotely,
and the thermostat configurations can be saved and accessed for reference. Detailed system
logging offers the opportunity to diagnose HVAC, sensor, or network issues. Several HZ-THSTAT
thermostats can be configured simultaneously or one at a time.
When the HZ-THSTAT is paired with the HZA-CONV-THSTAT-2WIRE Common Wire Adapter
accessory (sold separately), the thermostat can be used in installations without a common wire.
The HZ-THSTAT has local temperature and humidity sensors and accommodates up to four
remote temperature sensors (CHV-RTS, CHV-RSS, CHVI-RTS-1G-N-W, and
CHVI-RTS-1G-SM-W, sold separately) and up to two remote temperature/humidity sensors
(CHV-RTHS, sold separately) for optimized performance and flexibility. The HZ-THSTAT is also
compatible with 10k thermistors.
Supported Systems
The HZ-THSTAT can control the following heating and cooling systems with or without Humidity
control:
l 1 or 2-stage heat
l 1 or 2-stage cool
l 1 or 2-stage heat, 1 or 2-stage cool
l 1 or 2-stage heat, 1 or 2-stage cool heat pump with 1 or 2 stage auxiliary heat
l 1 or 2-stage heat, 1 or 2-stage cool dual fuel heat pump with 1 or 2 stage auxiliary heat
l Radiant floor only (floor warming and or space heating)
l 1 or 2 stage heat (stage 1 radiant floor with or without floor warming), 1 or 2 stage cool
l 1, 2, or 3 stage heat (stage 1 radiant floor with or without floor warming), 1 or 2 stage cool
heat pump with 1 stage aux heat
2 • HZ-THSTAT Product Manual — Doc. 8622A
l 1, 2, or 3 stage heat (stage 1 radiant floor with or without floor warming), 1 or 2 stage cool
dual fuel heat pump with 1 stage aux heat
NOTES:
l 2-stage heating: Unlike traditional furnaces that turn on and run at full capacity with
each demand for heating, 2-stage heat operates like two separate furnaces to maintain
a more consistent temperature in the 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 the 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.
l 2-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.

Installation
NOTE: Installers should have a strong working knowledge of HVAC systems.
The thermostat can be mounted directly to drywall, a low voltage mounting bracket (not
included), or to an electrical box (not included) for new or old work applications.
For mounting and installation instructions, refer to the HZ-THSTAT Quick Start.

Product Manual — Doc. 8622A HZ-THSTAT • 7
CAUTION: To avoid a possible short circuit, ensure excess wire is pushed back through the hole
in the backplate.
NOTES:
l This device is rated for 24VAC operation.
l For installations without a common wire, the HZA-CONV-THSTAT-2WIRE 2-wire power
adapter (sold separately) may be used. Refer to the Wiring Diagrams (on page9) section
for wiring details.
l A miniature flathead screwdriver (not supplied) may be required to attach thinner
gauged wires to the backplate terminals. Press the terminal release with the flathead
screwdriver while inserting the wires.
8 • HZ-THSTAT Product Manual — Doc. 8622A
R CONNECTIONS Switch
The thermostat pulls power from both R terminals and the C terminal. The position of the R
Connections switch decides which R connection is routed to the heat calls (W/W2).
NOTES:
l When using the HZA-CONV-THSTAT-2WIRE, always make connections to the R/RC
terminals and set the switch to R/RC ONLY.
l When power is not available from the HVAC system, a separate 24VAC transformer can
be connected between the RH and C terminals to provide power to the thermostat. Set
the R Connections switch to R/RC ONLY to ensure all calls use the R/RC reference.
Before attaching the thermostat, note the position of the R CONNECTIONS switch.
l For one R connection (24VAC reference), wire to the R/RC terminal and set the switch to
R/RC ONLY.
l For two R connections (24VAC reference), wire to the R/RC and RH terminals and set the
switch to SEPARATE.
The thermostat pulls power from both R connections and the C connection. The R Connections
switch dictates which R connection is routed to the heat calls (W/W2). When power is not
available from the HVAC system, a separate 24VAC transformer can be connected between the
RH and C terminals to provide power to the thermostat, and the R Connection must be set to
R/RC ONLY to ensure all calls use the R/RC reference.
NOTE: When using the HZA-CONV-THSTAT-2WIRE, always use R/RC terminal and set the R
Connections switch to R/RC ONLY.

After wiring the thermostat, plug the wire hole on the back of the thermostat with the included
foam insulation. The insulation prevents drafts and ensures accurate temperature readings.
NOTE: For Radiant Floor, if the Radiant type is Floor Warming, Space Heating, or Floor
Warm/Space Heat, always connect the radiant floor call wire to W2. Space Heating or Floor
Warm/Space Heat will always use the radiant floor as the first stage of heat.
