  • Page 7: Overview

    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.

  • Page 11: Installation

    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.

  • Page 12: System Connections

    System Connections Use the connections on the backplate to wire the thermostat to the HVAC system. Connections and Controls Description (1) Common from HVAC system 24VAC transformer. Used to power the device. (1) Reference for heat calls (W/W2) when using two separate reference connections. Used to power the device.
  • Page 13 CAUTION: To avoid a possible short circuit, ensure excess wire is pushed back through the hole in the backplate. NOTES:   This device is rated for 24VAC operation.   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.

  • Page 14: R Connections Switch

    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:   When using the HZA-CONV-THSTAT-2WIRE, always make connections to the R/RC terminals and set the switch to R/RC ONLY.
