Thermostats Crestron CHV-TSTAT and CHV-THSTAT Quick Installation Reference 1. Select a suitable location and run the connecting wires from the heating/cooling system and the Cresnet system. Refer to page 5 for a description of the thermostat connectors. Refer to page 7 for Network wiring details. Use the appropriate wiring diagram: • Heating or Cooling System Powered (Refer to page 8). • Separately Powered (Refer to page 9). • Two Wire Heat Only (Refer to page 9).
Crestron CHV-TSTAT and CHV-THSTAT Thermostats Thermostats: CHV-TSTAT and 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™ total control system. The thermostats are 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, i.e., CHV-TSTATB is a black unit.
Thermostats Crestron CHV-TSTAT and CHV-THSTAT Remote Sensors The current firmware release supports the addition of two optional remote sensors: temperature only (CHV-RTS) and/or temperature/humidity (CHV-RTHS), for both thermostats. Outdoor conditions can be imported from the optional external sensors CHV-RTS or CHV-RTHS, temperature and temperature/humidity respectively. Subsequent firmware releases will support the addition of up to four optional remote sensors, in any combination, for each thermostat.

Thermostats Crestron CHV-TSTAT and CHV-THSTAT Installation The location of the thermostat can affect its performance and efficiency. Install the thermostat away from direct sunlight, drafts, doorways, skylights, and windows. Also make sure the thermostat is conveniently located for programming, and do not mount on an exterior wall. The thermostats may be mounted directly to drywall or to a single-gang box. Refer to the following illustrations. Do the following to install the CHV-TSTAT or the CHV-THSTAT.

Thermostats Crestron CHV-TSTAT and CHV-THSTAT Appendix A: Glossary Anticipators – Used to anticipate the drop or rise in temperature and energize the appropriate system before reaching the set point. Balance Point – The lowest outdoor temperature at which the refrigeration cycle of a heat pump will supply the heating requirements without the aid of a supplementary heat source. Blower (Fan) – An air-handling device for moving air in a distribution system.
Crestron CHV-TSTAT and CHV-THSTAT Thermostats Appendix B: About Heat Pumps A heat pump extracts available heat from one area and transfers it to another. Even cold air contains some heat, and heat pumps can extract heat from the outside air on a cold day and transfer it indoors to maintain a comfortable temperature. A heat pump also works in reverse during the summer, extracting heat from indoors and transferring it outdoors.
