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. 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.
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.
Determine the Mounting Location
Install the thermostat away from direct sunlight, drafts, doorways, skylights, and windows. Also, make sure that the thermostat is conveniently located for control access and setup.
Follow the mounting requirements below:
The following tools and hardware are required for mounting the thermostat.
New Electrical Box or Low Voltage Mounting Bracket
Equipment included:
Equipment not included
Existing Electrical Box or Low Voltage Mounting Bracket
Equipment included:
Equipment not included:
Phillips screwdriver
Drywall
NOTE: A low-voltage mounting bracket is recommended for retrofit drywall installations.
Equipment included:
Equipment not included:
Mount the HZ-THSTAT
When mounting directly to drywall, use the included cutout template, a level (not included), and a utility knife (not included) to cut the mounting hole in the drywall
Cutout Template
NOTE: For drywall installations, use the included drywall anchors. Make sure to use the outer screw holes on the back plate. For electrical box and low voltage mounting bracket (not included) installations, use the inner screw holes on the back plate.
Mount to an Electrical Box or Low Voltage Mounting Bracket
For applications with an existing electrical box or low-voltage mounting bracket:
Mount the thermostat to an electrical box or low-voltage mounting bracket:
NOTE: Use a stud finder to avoid any studs behind the wall.
Mount to Drywall
For retrofit applications replacing an existing thermostat, turn the HVAC system power off and take a picture or label the current wire configuration before dismantling the current thermostat.
NOTES: When replacing a thermostat that was mounted to drywall with anchors, consider the following options: l move the installation up or down 1 in. from the existing position to avoid interference between the new and old anchor positions or
Make the necessary connections as called out in the illustrations. 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. Apply power after all connections have been made.
CAUTION: To avoid a possible short circuit, ensure the excess wire is pushed back through the hole in the backplate.
NOTES:
R CONNECTIONS Switch
The thermostat pulls power from both the R terminal and the C terminal. The position of the R Connections switch decides which R connection is routed to the heat calls (W/W2).
NOTES:
Before attaching the thermostat, note the position of the R CONNECTIONS switch.
Thermistor Curve
The thermostat is compatible with Crestron remote sensors and 10K thermistors. Refer to the table for information on the supported thermistor temperature curve.
Temperature | k-ohm |
-30°F (-34.4°C) | 185.42 |
0°F (-17.8°C) | 81.72 |
40°F (4.4°C) | 26.11 |
80°F (26.7°C) | 9.37 |
90°F (32.2°C) | 7.41 |
110°F (37.8°C) | 4.75 |
120°F (48.9°C) | 3.98 |
The following diagrams are a sampling of possible wiring solutions and do not represent all wiring options.
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.
Single Stage Heat/Cool System
2-Stage Heat Pump with 2-Stage Aux Heat
Wiring a Local Power Source
NOTE: If the HVAC system only requires one reference, a 24VAC power source can be used to power the device locally.
Before using the thermostat, ensure it is using the latest firmware. Check for the latest firmware at www.crestron.com/firmware. Load the firmware onto the thermostat using Crestron Toolbox™ software or a web-based user interface.
Configure the Device
