    CHV-THSTAT Introduction Functions and Features The CHV-TSTAT and CHV-THSTAT series are wall-mounted universal thermostats that can be part of a Crestron Home 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.

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 55 for more information.

    Thermostats Physical Description Refer to the following illustrations. The CHV-TSTAT and CHV-THSTAT are in a plastic enclosure with four buttons and an LCD display on the front. The back of the unit has ventilation slots, and holes for mounting the unit and wiring. The ventilation slots must be unobstructed for airflow to the unit.
  • Page 11 Connection View (Backplate, view from the front with cover removed) Ports The CHV-TSTAT and CHV-THSTAT have four types of connections on the inside back plate (refer to graphic above). NETWORK (Optional) – provides communication to the control system and Cresnet power to the CHV-TSTAT and CHV-THSTAT.
