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 9). • Separately Powered (Refer to page 9). • Three Wire Heat Only with Fan (Refer to page 10).
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, e.g., 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.

Crestron CHV-TSTAT and CHV-THSTAT Thermostats 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.
Thermostats Crestron CHV-TSTAT and CHV-THSTAT 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.
