CHV-TSTAT
Thermostat
 

The CHV-TSTAT and CHV-THSTAT are wall-mounted universal thermostats designed for seamless integration into a Crestron HomeŽ control network.

The CHV-TSTAT and CHV-THSTAT provide total control of single-stage and multi-stage heating and cooling systems, including conventional fossil fuel systems and heat pumps with auxiliary heat. The CHV-THSTAT offers all the functionality of the CHV-TSTAT, with humidity control.

Features include easy pushbutton selection of heating and cooling set points, with optional automatic changeover between heating and cooling modes; adjustable anticipator that prevents overshooting the set temperature; and optional continuous fan operation to keep air circulating for better comfort. The CHV-THSTAT can also provide outdoor low-temperature compensation to prevent condensation on windows during cold weather.

The CHV thermostats accept input from up to four remote sensors to ensure accurate monitoring; climate can be regulated according to the built-in sensors, the remote sensors, or any combination of sensor readings. The CHV thermostats can even be programmed to perform remote functions not possible with third-party thermostats, such as turning on lights or controlling window coverings.

The easy-to-read, backlit LCD display can show the current temperature and set point in either Fahrenheit or Celsius, outdoor temperature, and relative humidity. System mode and fan status indicators show when the equipment is running, while a message indicator displays maintenance notifications and filter change reminders.

The CHV-TSTAT and CHV-THSTAT can operate as standalone thermostats independent of the control system. When integrated into the Cresnet network, readings such as temperature, humidity, and operating mode can be seamlessly displayed on Crestron touch panels, allowing users to control and adjust the thermostats from any room in the Crestron Home. Users can also create their own convenient daily or weekly climate-control schedules from a touch panel, to maintain the desired level of comfort automatically while saving energy when the home is unoccupied.
