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, 2‑pipe and 4‑pipe FCU systems, 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 touch screen 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.

Using Crestron Toolbox™ software, the Thermostat Configuration Tool can be used to create a thermostat configuration, retrieve logs, and test relays. It can be used to load the configuration onto one or more thermostats at the same time. If a person is onsite, they can accept the transfer of a new thermostat configuration that is initiated remotely.

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.
